Steps / Instructions

Preheat the Oven: Preheat your oven to 350°F (175°C). Grease and flour two 9-inch round cake pans to ensure easy release after baking. Alternatively, you can line the bottoms with parchment paper for added convenience, which also helps prevent sticking.
Make the Graham Cracker Crust: In a medium bowl, combine the graham cracker crumbs, melted butter, and sugar. Mix until well combined, ensuring that the crumbs are fully coated with the butter. Press the mixture firmly into the bottom of each prepared cake pan to create an even layer that will hold its shape after baking. Bake for 10 minutes, then remove from the oven and set aside to cool while you prepare the cake batter. This crust will provide a delicious crunch that contrasts beautifully with the creamy frosting.
Prepare the Chocolate Cake Batter: In a large mixing bowl, whisk together the flour, sugar, cocoa powder, baking powder, baking soda, and salt until well mixed. Add the eggs, milk, oil, and vanilla extract. Mix on medium speed for 2 minutes until fully combined. Carefully stir in the boiling water; the batter will be thin, which is normal. This crucial step will create a moist cake texture that complements the graham cracker crust perfectly.
Bake the Cake: Pour the chocolate batter evenly over the cooled graham cracker crust in both pans. Bake for 30-35 minutes, or until a toothpick inserted into the center comes out clean. The cakes should have a slight spring when touched, indicating they are baked through. Allow the cakes to cool in the pans for 10 minutes before transferring to wire racks to cool completely. Cooling is crucial as it prevents the cake from becoming soggy when frosting.
Prepare the Marshmallow Frosting: In a large bowl, beat the softened butter until creamy and smooth, about 2-3 minutes. Gradually add the powdered sugar, mixing until smooth and well incorporated. Add the marshmallow fluff, vanilla extract, and a pinch of salt. Beat until fluffy and combined, which may take an additional 3-5 minutes. The frosting should be light and spreadable, perfect for decorating your cake with a generous layer that evokes the feel of toasted marshmallows.
Assemble the Cake: Once the cakes are completely cool, place one layer on a serving plate. Spread a generous layer of marshmallow frosting over the top, ensuring to reach the edges for a neat finish. Place the second cake layer on top and spread frosting over the top and sides of the cake. Make sure to smooth the frosting for an attractive finish; using an offset spatula can help achieve a professional look. This step is essential as it creates the perfect canvas for the garnishing.
Garnish the Cake: Top the frosted cake with mini marshmallows, chocolate chips, and a sprinkle of graham cracker crumbs for an authentic s’mores touch. For an extra special presentation, lightly toast the mini marshmallows with a kitchen torch to create a golden-brown appearance that invites your guests to dig in.
Serve: Slice the cake and serve immediately, or refrigerate until ready to enjoy. This cake is best served fresh, but can be stored in an airtight container in the refrigerator for up to 3 days. Allow it to come to room temperature before serving for the best texture, as this will ensure that the cake remains moist and the frosting soft.

Tips & Tricks

Storage: Keep the cake in an airtight container in the refrigerator to maintain its freshness. The frosting can become firmer when chilled, so allow it to sit at room temperature for a bit before serving to return it to a creamy consistency that enhances the cake’s enjoyment.
Make Ahead: The cake layers can be baked a day in advance. Wrap them tightly in plastic wrap and store in the refrigerator until you’re ready to frost and serve. This can help save time on the day you plan to enjoy the cake, making it a great option for busy bakers.
Avoiding Common Mistakes: Be sure to let the cakes cool completely before frosting to prevent the frosting from melting and sliding off, which can be frustrating. If your frosting is too thick, add a teaspoon of milk to achieve the desired consistency, ensuring it remains light and fluffy for the best finish.
Pro Technique: For an extra flavor boost, try adding a pinch of espresso powder to the chocolate batter to enhance the chocolate flavor, elevating the overall taste profile of your smores cake recipe. This subtle addition can deepen the chocolate’s richness, making your cake even more irresistible.
