Chocolate S’mores Cake: A Decadent Dessert for Every Occasion

There are desserts that simply bring joy, and then there’s the Chocolate S’mores Cake — a rich, gooey, and utterly irresistible treat that combines the nostalgic charm of campfire s’mores with the elegance of a layered cake. Whether you’re planning a family gathering, a cozy night in, or just looking for a sweet pick-me-up, this cake promises to satisfy every chocolate and marshmallow craving in one heavenly bite.

The History Behind the S’mores Cake

The classic s’more originated in the early 20th century, popularized by Girl Scouts as a campfire treat made of graham crackers, chocolate, and toasted marshmallows. The name itself is a contraction of “some more,” a nod to how addictive the snack can be. Over time, bakers and dessert lovers began to reinterpret the s’more in various forms — from bars and cookies to cupcakes and, eventually, the s’mores cake. The chocolate version, in particular, has become a fan favorite, blending the textures and flavors of the original with the sophistication of a multi-layered dessert.

Ingredients Breakdown: What Makes This Cake Special

At the heart of this Chocolate S’mores Cake are the three iconic components of a s’more: graham cracker crust, rich chocolate layer, and fluffy marshmallow topping. Here’s how each ingredient contributes to the magic:

  • Graham Crackers: Used for the crust and crumb layer, they add a buttery, slightly sweet base that contrasts beautifully with the rich chocolate.
  • Milk or Dark Chocolate: Melted into the filling or layered as ganache, chocolate brings the deep, indulgent flavor that s’mores lovers crave.
  • Marshmallows: Whether used in a meringue topping, a melted layer, or toasted on top, marshmallows provide that signature gooey texture and melt-in-your-mouth sensation.
  • Butter and Sugar: Essential for the crust and creamy layers, these ingredients enhance the richness and mouthfeel of the cake.
  • Heavy Cream or Condensed Milk: Often used to bind the layers or create a creamy texture in the filling or topping.

Step-by-Step Chocolate S’mores Cake Recipe

Ingredients

  • 1 ½ cups graham cracker crumbs
  • 6 tbsp unsalted butter, melted
  • ¼ cup brown sugar
  • 1 ½ cups all-purpose flour
  • ¾ cup unsweetened cocoa powder
  • 1 tsp baking soda
  • ½ tsp salt
  • 1 ½ cups granulated sugar
  • 2 large eggs
  • 1 tsp vanilla extract
  • 1 cup buttermilk
  • ½ cup vegetable oil
  • 1 cup hot water
  • 12 oz semisweet chocolate chips
  • 14 oz can sweetened condensed milk
  • 1 ½ cups mini marshmallows
  • Additional marshmallows for topping

Directions

  1. Preheat oven to 350°F (175°C). Grease and flour a 9×13-inch baking pan.
  2. Make the crust: Combine graham cracker crumbs, melted butter, and brown sugar. Press firmly into the bottom of the pan. Bake for 10 minutes. Let cool slightly.
  3. Prepare the cake batter: In a large bowl, sift together flour, cocoa powder, baking soda, and salt. In another bowl, whisk together sugar, eggs, and vanilla. Add oil and buttermilk, mixing until smooth.
  4. Gradually combine wet and dry ingredients. Stir in hot water until just mixed (the batter will be thin).
  5. Pour the batter over the baked crust. Bake for 25–30 minutes or until a toothpick inserted in the center comes out clean. Let cool completely.
  6. Layer the chocolate: Melt chocolate chips in a heatproof bowl over a double boiler or in the microwave. Spread evenly over the cooled cake.
  7. Add the marshmallow layer: Spread sweetened condensed milk over the chocolate layer. Sprinkle mini marshmallows evenly on top.
  8. Broil the topping: Place the cake under a preheated broiler for 1–2 minutes until the marshmallows are golden brown. Watch carefully to avoid burning.
  9. Cool completely before slicing. For best results, refrigerate for at least 1 hour before serving.

Pro Tips for Perfect Chocolate S’mores Cake

  • Use a kitchen torch to toast the marshmallows for a more authentic s’more experience.
  • Chill the cake overnight for a firmer texture and more intense flavor.
  • If using a cake pan with a removable bottom, it makes slicing and serving much easier.
  • For a smoother chocolate layer, add a splash of heavy cream to the melted chocolate before spreading.

Variations and Customizations

The beauty of this Chocolate S’mores Cake lies in its versatility. Here are some exciting ways to customize it:

  • Double Chocolate: Add a layer of chocolate ganache between the cake and the marshmallow topping.
  • Peppermint Twist: Stir a few drops of peppermint extract into the marshmallow layer or drizzle peppermint-flavored white chocolate on top.
  • Sea Salt Addition: Sprinkle a pinch of flaky sea salt over the marshmallow topping before broiling for a sweet-and-salty contrast.
  • Gluten-Free: Substitute graham crackers with gluten-free digestive biscuits and use gluten-free flour in the cake batter.
  • Vegan Version: Use vegan graham crackers, coconut oil instead of butter, and vegan marshmallows. Substitute eggs with flax eggs and use plant-based milk in place of buttermilk.

Health Considerations and Nutritional Value

While the Chocolate S’mores Cake is undeniably indulgent, understanding its nutritional profile helps you enjoy it responsibly:

  • Sugar Content: This cake is high in sugar due to the marshmallows, chocolate, and condensed milk. Consider reducing the sugar in the crust or using dark chocolate with a higher cocoa content to cut sweetness.
  • Fat Content: The butter, condensed milk, and oil contribute to the rich texture. For a lighter version, substitute some of the oil with applesauce or mashed banana.
  • Portion Control: Due to its density and richness, smaller slices are often more satisfying. Aim for 1-inch slices and savor each bite.
  • Calories per Serving (approx.): Around 350–450 calories per slice, depending on size and ingredients used.

Can I make this cake ahead of time?

Yes! This cake keeps well in the refrigerator for up to 3 days. In fact, chilling it overnight enhances the flavors and texture.

How do I store leftovers?

Store in an airtight container or tightly wrapped with plastic wrap in the refrigerator. Let sit at room temperature for 10–15 minutes before serving for the best texture.
