For those who own a Ninja Foodi, these instructions are equally applicable, though you might also enjoy our dedicated air fryer brownies recipe for a different texture.
Why Choose a Pressure Cooker for Brownies?
You might wonder why you would use a pressure cooker instead of your traditional oven for baking brownies. The answer lies in convenience and efficiency, especially during warmer months. When summer temperatures soar to 90 degrees Fahrenheit or higher, the last thing you want is to heat up your entire kitchen by running the oven. This is where countertop appliances like the Instant Pot or Ninja Foodi shine. They allow you to prepare delicious baked goods without contributing to indoor heat, making them a top choice for desserts during any season.
Beyond beating the heat, pressure cooking offers consistent moisture, resulting in incredibly fudgy brownies every time. The enclosed environment of the pressure cooker traps steam, preventing your brownies from drying out and ensuring that coveted dense, moist texture. It’s also remarkably hands-off once you set the timer, freeing you to focus on other tasks while your dessert cooks to perfection.
Getting Started with Pressure Cooking Desserts
If pressure cooking is a new venture for you, welcome! We offer a wealth of easy one-pot meal recipes, but let’s begin with a few fundamental tips crucial for any pressure cooking endeavor:
- Familiarize yourself with your specific pressure cooker model. While general principles apply, understanding your appliance’s unique features is vital.
- For consistent results, ensure accurate measurements of both ingredients and the water added to the pot for steaming.
- Consider investing in a non-stick inner pot. While not strictly necessary, it significantly simplifies cleaning and helps prevent food from sticking, particularly when sautéing ingredients before pressure cooking. A well-maintained pot also reduces issues like food residue that might require deglazing.
For context, the recipes shared here are typically developed using a 6-quart Instant Pot model. This size is versatile for a wide range of dishes, including this brownie recipe.

This method is particularly ideal when you’re cooking for a smaller household or simply craving a sweet treat after dinner without committing to a large batch. While I adore making homemade brownies in all forms, the inspiration for these pressure cooker delights came after experiencing the sheer joy of a perfectly made brownie in a mug. I realized the potential for a similarly quick and satisfying dessert on a larger, yet still manageable, scale.
The Magic of Fudgy Pressure Cooker Brownies with a Gooey Center
Imagine a rich, dark chocolate brownie with a hidden well of warm, gooey peanut butter that oozes out with every bite. This optional, yet highly recommended, addition transforms a fantastic brownie into an extraordinary culinary experience. While it’s certainly not a requirement, the indulgent burst of flavor and texture from a melted peanut butter core is simply unparalleled.
We’ve experimented with various fillings to find the ultimate combination. Beyond the classic peanut butter, we’ve tried caramel, often using Rolo candies for a delightful surprise. However, our team universally agrees: peanut butter reigns supreme! For the best results, stick with a creamy peanut butter – the specific brand is less important than its smooth consistency, which melts beautifully into the brownie.

Perfectly Timed: How Long to Cook Brownies in Your Instant Pot
For a family of five, a single batch of these brownies, cooked to perfection, provides a satisfying dessert that’s rich enough that a small piece is usually all you need. The entire process, from prep to cool-down, typically takes about an hour to achieve that desired decadent texture. This recipe was adapted from traditional baking methods to suit the pressure cooker, specifically for a smaller, 6-inch pan, as a standard square pan wouldn’t fit.
To create these mouth-watering quick and easy dessert recipes, we rely on a 6-inch springform pan. While Crockpot brownies are also a delightful option, the pressure cooker method offers a significantly faster cooking time. Given the compact size of an Instant Pot, a “regular” baking pan won’t fit, making a specialized 6-inch springform pan essential. Don’t worry, this pan is a versatile kitchen tool you’ll find yourself reaching for to make cheesecakes, small cakes, and other delightful treats long after you’ve mastered these brownies.
Once your brownie batter is poured into the springform pan and cooked, the pan’s design makes for an effortless release. After cooling, simply unlatch the side, and the outer rim lifts away, leaving your perfectly formed brownie ready for slicing and serving. If you’re new to using a springform pan, you’ll find it incredibly convenient and fun, especially when aiming for clean, elegant slices.

If you’re a fan of flourless chocolate cake with its characteristic dense, fudgy consistency, then you are going to adore these pressure cooker brownies. Their rich, indulgent texture is remarkably similar and utterly irresistible. This is a truly decadent treat that, while incredibly satisfying, I find myself making perhaps once a month, lest I become completely consumed by its deliciousness. It’s simply too good to resist!
Essential Ingredients for Decadent Pressure Cooker Brownies
Crafting these extraordinary brownies begins with a careful selection of common baking ingredients. Here’s a breakdown of what you’ll need and some tips for each:
- **All-Purpose Flour:** This provides the foundational structure for your brownies. While they will be dense, a small amount of baking powder helps achieve a slight lift and a tender crumb. Proper flour measurement is crucial; avoid packing it tightly into your measuring cup to prevent an overly dense or dry result.
- **Melted Butter:** I personally prefer Kerrygold salted butter for its rich flavor, but any quality butter will work. If you have dietary restrictions, a dairy-free alternative can be successfully substituted. Ensure your butter is melted and slightly cooled before mixing.
- **White Granulated Sugar:** This sweetens the brownies to perfection, contributing to their classic flavor and moist texture. While I haven’t personally tested it with sugar-free alternatives like Splenda, many bakers find such substitutes work well in similar recipes.
- **Unsweetened Cocoa Powder:** This is where the deep chocolate flavor comes from. The quality of your cocoa powder can significantly impact the final taste, so opt for a good quality brand, whether it’s regular unsweetened or a dark chocolate variety for a more intense flavor.
- **Vanilla Extract:** A touch of vanilla enhances the chocolate flavor and adds a layer of warmth and complexity to the brownies.
- **Baking Powder:** As mentioned, this leavening agent provides a subtle lift, giving the brownies a slight fluffiness while maintaining their characteristic fudgy density.
- **Large Eggs:** Eggs are essential for binding the ingredients, adding moisture, and contributing to the rich, dense texture. For the best results and a smoother batter, ensure your eggs are at room temperature before mixing.
Convenience with Boxed Brownie Mix
For those times when you’re short on time or simply prefer the convenience, using a boxed brownie mix is perfectly acceptable for this pressure cooker recipe. However, there are a couple of considerations to keep in mind. Depending on the brand, a standard boxed mix (like Ghirardelli, which often yields enough for two standard pans) might produce too much batter for a single 6-inch springform pan. You should never fill your pressure cooker pan more than two-thirds full to allow for expansion. This may mean cooking your brownies in two separate batches.
The cooking time for a single batch in the 6-inch springform pan would generally remain the same as with the homemade recipe. If you decide to make brownie bites using an egg mold, as explained below, the timing would need to be adjusted accordingly due to the smaller portion sizes.
Choosing the Right Pan: Springform or Molds
To achieve the beautiful, cleanly released brownies featured here, a metal 6-inch springform pan is indispensable. I’ve linked the specific pan I use for my 6-quart Instant Pot in the recipe card below, ensuring a perfect fit. Additionally, you’ll need pre-cut parchment paper circles to line the bottom of the pan, which guarantees an effortless release of your fudgy creation. A trivet is also crucial; this will keep your pan elevated above the water inside the pressure cooker, preventing it from boiling directly. A trivet with handles is particularly convenient for safely lowering and lifting the pan.

But wait, there’s another fun and charming way to prepare these brownies: as adorable mini brownie bites! These bite-sized delights are a huge hit with kids and make for perfect individual servings. They’re super easy to pop into your mouth, and a fantastic way to enjoy a small portion of this decadent dessert.
Delightful Brownie Bites: A Fun Alternative
If you’re looking for a fun, portion-controlled, or kid-friendly version of these fudgy brownies, making them into brownie bites using an egg mold is a fantastic option. You can use either the homemade brownie batter from this recipe (minus the peanut butter filling) or a boxed brownie mix.
Here’s how to make perfect pressure cooker brownie bites:
- Prepare your brownie batter as directed.
- Lightly spray your egg mold with non-stick cooking spray.
- Fill each cavity of the egg mold approximately three-quarters of the way full. Do not overfill, as the batter will expand during cooking.
- Once filled, cover the entire egg mold tightly with aluminum foil. This prevents condensation from dripping onto the brownies.
- Pour 1.5 cups of water into the inner pot of your pressure cooker.
- Place a trivet inside the pressure cooker, then carefully set your covered egg mold on top of the trivet.
- Secure the pressure cooker lid and set the steam release valve to the sealing position.
- Cook on high pressure for 22 minutes.
- After the cooking cycle is complete, allow for a natural release of pressure. This means you do not touch the steam valve; let the pressure release gradually on its own. This typically takes around 10-15 minutes.
- Once the pressure has fully released, carefully remove the egg mold from the pressure cooker.
- Remove the foil and let the brownie bites cool completely in the mold before attempting to pop them out. This is crucial for them to hold their shape and achieve their best texture.
- Serve and enjoy these delightful mini treats!
Ninja Foodi Pressure Cooker Brownies: The Same Delicious Results
For owners of a Ninja Foodi, you’ll be pleased to know that you can follow the exact same instructions as outlined above for the Instant Pot. When pressure cooking in the Ninja Foodi, simply ensure you are using the pressure cooking lid (the one that is not permanently attached) and set the valve to seal. The result will be the same wonderfully dense, ooey-gooey brownies with a consistency akin to a rich flourless chocolate cake.
As mentioned, the peanut butter-filled version is absolutely amazing, especially if you’re a fan of the classic chocolate and peanut butter combination! For a 6-inch springform pan, 50 minutes on high pressure has proven to be just the right amount of time for a perfectly fudgy brownie. However, if you prefer an even gooier consistency, you might experiment by reducing the cooking time by a few minutes. The first attempt is always a trial to discover your ideal texture, so don’t hesitate to make a note of your preferred cooking time when you print out this recipe for future reference.

Equipment
- 1 (6-inch) springform pan
- Parchment paper circles (to fit inside the bottom of the pan)
- Trivet with handles (for Instant Pot/Ninja Foodi)
Ingredients
- 5 tbsp butter, softened or melted (Kerrygold recommended)
- 1/4 cup unsweetened cocoa powder (high quality for best flavor)
- 1 cup granulated sugar (standard white sugar)
- 3/4 cup all-purpose flour (measured correctly, not packed)
- 1/4 tbsp vanilla extract (pure vanilla is best)
- 3/4 tsp baking powder
- 2 large eggs (at room temperature)
- 1 1/2 cup water (for inside the pressure cooker)
- 1 tbsp creamy peanut butter, optional (for filling)
Instructions
- In one bowl, combine all dry ingredients (cocoa powder, sugar, flour, baking powder). In another bowl, combine all wet ingredients (melted butter, vanilla, eggs). Stir each bowl separately until just combined.
- Add the wet ingredients to the dry ingredients and stir until just combined. Do not overmix. If adding nuts or chocolate chips, fold them into the brownie mixture at this stage.
- Generously spray the inside walls of your 6-inch springform pan with non-stick cooking spray.
- Lay a pre-cut parchment paper liner into the bottom of the pan. If adding a filling, place 1 tablespoon of peanut butter (or caramel pieces) directly in the center of the pan.
- Carefully pour the brownie batter over the filling (if using) and spread it evenly across the pan to ensure consistent thickness.
- Cover the top of the springform pan tightly with aluminum foil. This prevents any condensation from dripping onto the brownies during cooking.
- Pour 1 1/2 cups of water into the inner pot of your Instant Pot or Ninja Foodi. Place a trivet inside the pot, ensuring it is stable.
- Carefully place the foil-covered springform pan onto the trivet.
- Secure the pressure cooker lid and ensure the steam release valve is set to the sealing position.
- Set the pressure cooker to Manual or High Pressure for 50 minutes for a 6-inch pan.
- Once the cooking cycle is complete and the pressure cooker beeps, do not immediately release the pressure. Allow for a natural release for 10 minutes. This means you should leave the steam valve untouched until the display indicates “10” (or for 10 minutes if your model doesn’t show a timer). After 10 minutes, carefully open the steam release valve to quick release any remaining pressure.
- Carefully remove the springform pan from the pressure cooker. Allow the brownies to cool completely in the pan on a wire rack. This is crucial for achieving the perfect fudgy texture and ensuring they hold their shape.
- Once completely cool, release the clasp on the side of the springform pan and gently remove the outer rim. Carefully place a plate on top of the brownie, flip it over, then remove the bottom of the pan and the parchment paper. Slice and serve. These brownies will have a very dense, fudgy, flourless cake-like consistency.

Tips for the Best Pressure Cooker Brownies
- **Do Not Overmix:** Once the wet and dry ingredients are combined, stir only until no streaks of flour remain. Overmixing develops gluten, which can lead to a tougher, less fudgy brownie.
- **Natural Release is Key:** The 10-minute natural release period is crucial. It allows the brownies to continue cooking gently as the pressure slowly dissipates, preventing them from deflating and ensuring a moister, more tender texture.
- **Cool Completely:** Patience is a virtue when it comes to brownies! Allowing them to cool completely in the pan ensures they set properly, making them easier to slice and enhancing their fudgy consistency. Warm brownies tend to be crumbly.
- **Achieving Your Preferred Gooeyness:** The 50-minute cook time provides a perfectly fudgy brownie. If you prefer them even gooier, you can try reducing the cook time by 3-5 minutes. Remember to note your ideal time for future batches!
- **Preventing a Burnt Bottom:** Always use the specified amount of water (1.5 cups) in the inner pot and ensure your pan is elevated on a trivet. This creates a steam bath, preventing direct contact with the heating element and ensuring even cooking without burning.
Serving and Storage Suggestions
These pressure cooker brownies are fantastic on their own, but they truly shine with a few simple additions. Serve them warm with a scoop of vanilla bean ice cream that slowly melts into the fudgy goodness, or a dollop of freshly whipped cream. A dusting of powdered sugar adds a touch of elegance, especially to the peanut butter-filled variety. For those who love a bit of texture, a sprinkle of sea salt can beautifully balance the sweetness of the chocolate.
To store any leftover brownies, once completely cooled, cut them into individual squares. Place them in an airtight container at room temperature for up to 3-4 days. For longer storage, you can refrigerate them for up to a week. For an extra treat, try warming them slightly in the microwave for a few seconds before serving to reactivate that gooey texture!
Frequently Asked Questions About Instant Pot Brownies
- **Can I use a different size pan?** This recipe is optimized for a 6-inch springform pan. Using a different size would alter the cooking time significantly. A larger pan would likely require more time, and a smaller, deeper pan might need more time or could result in an undercooked center. It’s best to stick to the recommended size.
- **Can I make these gluten-free?** While this recipe uses all-purpose flour, many gluten-free all-purpose flour blends are formulated for 1:1 substitution in baking. However, results may vary slightly in texture.
- **My brownies seem too moist/wet after cooling. What went wrong?** This typically means they were slightly undercooked. Next time, add 3-5 minutes to the pressure cooking time. Ensure you’re always performing the 10-minute natural release, as this is part of the cooking process.
- **Can I use oil instead of butter?** Yes, you can substitute a neutral-flavored oil (like vegetable or canola oil) for melted butter in equal amounts. However, butter often adds a richer flavor to brownies.
