The concept of desserts in jars has been a personal favorite for years.

This particular s’mores creation emerged from our desire to blend that easy cake-in-a-jar method with the ultimate campfire treat. The result? A fuss-free, intensely satisfying dessert that captures the essence of s’mores without needing a roaring fire. It’s a testament to how simple ingredients can come together to create something truly magical and memorable.

Essential Ingredients for Perfect Baked S’mores

Creating these delightful s’mores in a jar is surprisingly simple, especially with our smart ingredient choices. Here’s a closer look at what you’ll need and why:

  1. Devil’s Food Cake Mix: This is our secret shortcut to a rich, chocolatey cake base. While you could certainly bake from scratch or use a different cake flavor, Devil’s Food cake mix ensures a consistently decadent chocolate flavor and simplifies the preparation process significantly. It provides the perfect foundation for our s’mores creation.
  2. Dark Soda (Coke, Dr. Pepper, or Chocolate Soda): This might sound unconventional, but a can of dark soda is the magical ingredient that transforms the cake mix into a luscious batter with incredible depth of flavor. Coke or Dr. Pepper work wonderfully, but for the ultimate chocolate intensity, root beer truly stands out, enhancing the cocoa notes of the cake mix. If you can find chocolate soda, it’s an absolute game-changer for an extra layer of chocolate goodness.
  3. Chocolate Chips: No s’mores are complete without chocolate! We recommend using mini chocolate chips for an even distribution, ensuring you get a delightful burst of melted chocolate in every bite. For an extra touch of indulgence, you can also break up a chocolate bar into smaller pieces and press them into the top of the cake right out of the oven, allowing them to melt beautifully.
  4. Large Marshmallows: The star of any s’mores, large marshmallows are placed into the baked cake and lightly toasted in the oven to create that signature ooey-gooey center. While classic white marshmallows are perfect, feel free to use multi-colored ones for a fun twist. Alternatively, you can use marshmallow fluff spooned over the top, mini marshmallows to fill the center, or even a layer of chocolate ganache before adding your marshmallow topping for a truly luxurious experience.
  5. Graham Cracker Crumbs: To capture the full s’mores experience, a sprinkle of graham cracker crumbs is essential. Using crumbs instead of whole pieces ensures a delicate, crunchy texture that complements the soft cake and melted marshmallow perfectly.

Our philosophy revolves around making delicious desserts accessible and enjoyable. That’s why we lean on the genius of a two-ingredient soda cake recipe for the base of these incredible oven-baked s’mores. It’s truly as simple as combining a cake mix with a can of soda to create a moist, flavorful chocolate cake that forms the heart of this jarred delight. This simple approach means less time prepping and more time savoring!

Creative Variations and Substitutions for Your S’mores Jars

The beauty of this recipe lies in its versatility. While we love the classic combination, don’t hesitate to get creative! As mentioned, different sodas can dramatically change the flavor profile of your cake base. Experiment with Dr. Pepper for a distinct, spiced cherry note, or seek out chocolate soda for an ultra-chocolatey foundation. Amp up the chocolate factor even further by increasing the amount of chocolate chips, ensuring an extra gooey center. These s’mores are baked in 1/2 Pint Mason Jars, which are absolutely perfect for individual servings, making them a fantastic single-serving dessert option. They’re just the right size for a satisfying treat without overindulging.

Equipment

  • 12 small mason jars
  • 1 Mixing Bowl

Ingredients

  • 1 box chocolate cake mix (Devil’s food is recommended for best results)
  • 1 can dark soda (Coke, Dr. Pepper, or Chocolate soda; root beer for deepest flavor)
  • 1/2 cup chocolate chips (mini preferred for even distribution)
  • 10 large marshmallows
  • 10 bars chocolate bar (for melting on top, optional)
  • 1 cup graham cracker crumbs

Instructions

  1. In a large mixing bowl, thoroughly combine the can of soda and the chocolate cake mix until a smooth batter forms.
  2. Gently fold in the chocolate chips, ensuring they are well distributed throughout the batter.
  3. Arrange your mason jars on a cookie sheet. Lightly spray the inside of each jar with non-stick cooking spray.
  4. Carefully pour approximately 1/2 cup of cake batter into each prepared mason jar.
  5. Bake at 350°F (175°C) for about 20-23 minutes. The cakes are ready when the center is firm and springs back slightly when gently touched.
  6. Remove the jars from the oven. Using a fork, gently make a small indentation or hole in the center of each cake.
  7. Place one large marshmallow into the hole in the center of each cake.
  8. Return the jars to the oven for an additional 2-3 minutes, just long enough for the marshmallows to become soft and slightly gooey.
  9. Take the jars out of the oven. Immediately sprinkle a generous amount of graham cracker crumbs over the top of each marshmallow.
  10. If desired, place one piece of chocolate bar on top of the warm marshmallow in each jar, allowing it to melt into a luscious topping.
  11. Serve and enjoy these warm, delightful S’mores in a Jar immediately for the best experience!

For an extra layer of decadence, consider adding a dollop of peanut butter on top of the warm s’mores, or serve them à la mode with a scoop of your favorite vanilla bean ice cream. These baked s’mores are truly best enjoyed warm, right out of the oven, when the chocolate is molten and the marshmallow is perfectly toasted. However, if you have any leftovers (which is rare!), they can be stored at room temperature in airtight containers or freezer bags for a day or two. Kids especially adore this concept as it’s a perfectly portioned treat just for them, and you’ll love that there’s no slicing or serving fuss involved!

Is it Safe to Bake in Mason Jars? Your FAQs Answered

A common question when baking in glass is about safety. Yes, it is generally safe to bake in mason jars, but a few precautions are essential to ensure a successful and safe baking experience:

  • Choose Quality Jars: Always use mason jars from trusted brands like Ball or Kerr, which are designed to withstand temperature changes.
  • Inspect for Imperfections: Before baking, carefully check each jar for any cracks, chips, or imperfections. Even a tiny flaw can cause the glass to crack under heat.
  • Avoid Thermal Shock: To prevent thermal shock (which can cause glass to break), never place cold jars directly into a hot oven. It’s best to place the filled jars into a cold oven and then allow both to heat up together. Alternatively, warm the jars slightly before filling and placing them in a preheated oven.
  • Don’t Overfill: Leave adequate headspace in each jar to allow the cake to rise without overflowing.

By following these simple guidelines, you can safely enjoy the convenience and charm of baking in mason jars. They’re a fantastic choice for individual desserts, making cleanup a breeze and presentation a joy.

These individual s’mores jars are incredibly versatile for various occasions. They’re perfect for a s’mores-themed birthday party, a cozy “glamping” experience in your backyard without the fuss of a real campfire, or simply as a fun, decadent dessert to brighten up any weeknight. They offer all the beloved flavors of summer campfires, transformed into a chic and convenient treat for any time of year.
