• Sugar – Granulated sugar for sweetness.
• Oil – Vegetable oil for moisture.
• Liquid – Buttermilk or whole milk thins the batter.
• Whole Eggs – Large eggs stabilize the homemade chocolate cake batter.
• Flavoring – Vanilla extract balances the flavor of the chocolate.
• Between the Layers – Graham cracker crumbs and marshmallow cream (marshmallow fluff).
• Marshmallow Buttercream – Marshmallow fluff, powdered sugar (confectioner’s sugar) and vanilla extract.
• Chocolate Ganache – Milk chocolate chips and heavy cream.
• Garnishes – Fun size Hershey candy bars, marshmallow creme, mini marshmallows, large marshmallows and broken or crushed graham crackers. To decorate with swirls of marshmallow creme as pictured see the Cook’s notes in the recipe card.

How to Make the BEST S’mores Cake Recipe

• Heat Oven and Prepare the Cake Pans – Prepare four 8-inch round cake pans with baking spray.
• Sift Dry Ingredients – Whisk to sift together the flour, cocoa powder, baking powder and salt.
• Combine the Wet Ingredients – Use a mixer to beat the butter, oil, and granulated sugar until smooth and light then add the eggs.
• Add the Flour Mixture to the Bowl – Gradually add the sifted flour mixture alternating with the milk until fully combined.
• Transfer Cake Batter to the Pans – Divide the batter evenly between the prepared cake pans.
• Oven – Bake per the ook time in the recipe or until a toothpick can be inserted into the center comes back clean.
• Cool Completely – Cool cake layers in the pans on a cooling rack while making the frosting.
• Make the Frosting –  Use an electric mixer on medium-high speed to beat together the butter, marshmallow creme, and vanilla extract. Gradually add the powdered sugar until completely combined.
• Make the Chocolate Ganache – Pour warm heavy cream over the chocolate chips. Let sit to let the chocolate melt. Stir until smooth.
• Assemble the Cake –  Stack layers with a generous layer of plain marshmallow creme between each layer and sprinkle with graham cracker crumbs.
• Marshmallow Buttercream – Frost the top and sides of the cake with marshmallow buttercream.
• Ganache – Pour the ganache over the top of the cake and use the tip of an icing spatula to gently spread into an even layer allowing some ganache to drip down the sides. Gently press reserved graham cracker crumbs around the bottom of the cake.
• Decorate the Top of the S’mores Cake: You can top the cake with toasted swirls of marshmallow cream (See Cook’s note as pictured.) or use mini marshmallows or large marshmallows piled on top. Decorate with chocolate candy bars (i.e. Hershey bars) or drop dollops of marshmallow creme adding graham crackers for decoration.

Kitchen Equipment to Make S’mores Layer Cake

• A stand mixer or hand mixer.
• Large bowl and medium bowl.
• Measuring cups and spoons.

• A large whisk for sifting the dry ingredients.
• Offset spatulas for frosting the cake.

Recipe Variations and Substitutions

• Chocolate – You can use semi-sweet chocolate chips or dark chocolate chips in place of milk chocolate for the ganache.
• Eyeball the Layers – When adding the graham cracker crumbs to the layers, you can use anywhere from 1/4-1/3 cup of crumbs. Have extra on hand and add more or less to suit your fancy.
• Garnishes – To garnish this cake you can have fun! To garnish as pictured, use a large open star tip (Wilton 1M) to pipe generous swirls of homemade marshmallow cream and then toast it using a pastry torch.
• Easy Marshmallow Topping – If you prefer, you can pile marshmallows on top and then toast them with a kitchen torch or pop the cake under the broiler just until they’re toasted. Don’t walk away! Drizzle the marshmallows with additional melted chocolate or arrange mini Hershey bars and graham crackers on top.
