S’mores Chocolate Cake

A decadent dessert that combines rich chocolatey goodness with childhood nostalgia, featuring layers of moist chocolate cake, creamy marshmallow frosting, and silky chocolate ganache.

Ingredients

Scale
  • 2 cups all-purpose flour
  • 2 cups granulated sugar
  • 3/4 cup natural unsweetened cocoa powder
  • 2 tsp baking soda
  • 1 tsp salt
  • 2 large eggs
  • 1 cup milk
  • 1 cup vegetable oil
  • 1 1/2 tsp vanilla extract
  • 1 cup hot water
  • 3/4 cup graham cracker crumbs
  • 1 1/2 tbsp granulated sugar (for crumbs)
  • 1/4 cup unsalted butter, melted
  • 1 3/4 cups unsalted butter (for frosting)
  • 3 1/4 cups marshmallow fluff
  • 6 cups powdered sugar (for frosting)
  • 1 1/2 cups mini marshmallows
  • 9 oz semi-sweet chocolate chips
  • 3/4 cup heavy whipping cream (for ganache)
  • 3/4 cup unsalted butter (for vanilla frosting)
  • 3 cups powdered sugar (for vanilla frosting)
  • 1 tsp vanilla extract (for vanilla frosting)
  • 1 tbsp milk or cream (for vanilla frosting)

Instructions

  1. Preheat your oven to 350°F (175°C). Grease and flour two 9-inch round cake pans.
  2. In a large mixing bowl, combine the flour, sugar, cocoa powder, baking soda, and salt. Mix thoroughly to incorporate.
  3. Add the eggs, milk, vegetable oil, and vanilla extract to the dry ingredients. Beat on medium speed for about 2 minutes until smooth.
  4. Carefully stir in the hot water. Note that the batter will be thin, which is normal.
  5. Divide the batter evenly between the prepared cake pans. Bake for 30-35 minutes or until a toothpick inserted into the center comes out clean. Allow the cakes to cool in the pans for a few minutes before transferring them to a wire rack.
  6. To make graham cracker crunchies, mix the graham cracker crumbs, 1 1/2 tablespoons of sugar, and melted butter in a bowl. Spread the mixture on a baking sheet and bake at 350°F for 10-12 minutes until golden. Let cool.
  7. For the marshmallow frosting, beat the unsalted butter until creamy. Gradually add the marshmallow fluff and powdered sugar until combined and fluffy.
  8. To prepare the ganache, heat the heavy cream until it simmers. Pour the hot cream over the chocolate chips and let it sit for 5 minutes, then stir until smooth.
  9. For the vanilla frosting, beat the unsalted butter until creamy. Add the powdered sugar, vanilla extract, and milk, continuing to mix until smooth.
  10. Assemble the cake: Place one layer on a serving plate, spread a generous layer of marshmallow frosting over the top, sprinkle with graham cracker crunchies and mini marshmallows, then add the second layer.
  11. Pour the chocolate ganache over the top of the cake, allowing it to drip slightly down the sides. Finish with vanilla frosting and additional decorations as desired.

Notes

Ensure ingredients are at room temperature for better mixing. Store leftover cake in an airtight container at room temperature for up to 3 days.
