👨🍳 Preparation
- 1
Preheat your oven to 350°F. Grease and line two 8-inch round cake pans with parchment paper, then set aside.
- 2
In a medium bowl, sift together the graham cracker crumbs, all-purpose flour, and baking powder. Whisk to combine and set aside.
- 3
In a large bowl, beat the softened butter and granulated sugar together until the mixture is light and fluffy, about 5 minutes.
- 4
Add the eggs one at a time, beating well after each addition. Stir in the vanilla extract.
- 5
Alternately add the dry graham cracker mixture and the milk to the butter mixture, beginning and ending with the dry ingredients. Mix until just combined after each addition.
- 6
Divide the batter evenly between the prepared pans and smooth the tops.
- 7
Bake for 25 to 35 minutes, or until a toothpick inserted into the center comes out clean.
- 8
Let the cakes cool in the pans for 15 minutes, then transfer to a wire rack to cool completely.
- 9
While the cakes cool, prepare the fudge frosting: melt the chopped unsweetened chocolate over a double boiler until smooth. Remove from heat and let cool slightly.
- 10
Warm the sweetened condensed milk in the microwave for about 10 seconds until just warm to the touch. Stir the warm condensed milk into the melted chocolate until fully combined.
- 11
Refrigerate the frosting for about 10 minutes, stirring occasionally, until it firms up but is still spreadable. Before frosting, let it come to room temperature or gently warm over a double boiler while stirring to soften if needed.
- 12
To assemble, level the tops of the cakes by slicing off any domed parts to create flat surfaces.
- 13
Spread the marshmallow fluff evenly over one cake layer, leaving a small border around the edges to prevent spilling.
- 14
Place the second cake layer on top, flat side down.
- 15
Frost the entire cake with the chocolate fudge frosting.
- 16
Serve with extra marshmallows on the side for a fun finishing touch.
🧠 Why It Works
This s’mores layer cake achieves its unique texture and flavor through a careful balance of ingredients. Graham cracker crumbs replace much of the flour, lending a slightly crumbly yet tender crumb that echoes the classic s’mores taste. The baking powder provides reliable leavening, ensuring the cake rises evenly without becoming dense. Creaming the butter and sugar incorporates air, contributing to a light, fluffy structure. Marshmallow fluff adds gooey moisture and sweetness, while the two-ingredient chocolate fudge frosting—made from unsweetened chocolate and sweetened condensed milk—creates a rich, silky finish. Avoid overmixing to prevent toughness and ensure the cake remains soft and moist.
🛠️ Troubleshooting
Why is my s’mores cake dry after baking?
Dryness often results from overbaking or using too much flour relative to wet ingredients. Ensure you measure ingredients accurately, avoid overmixing, and check the cake at the minimum baking time with a toothpick.
What if my cake layers are dense and heavy?
Dense layers can occur if the butter and sugar aren’t creamed enough to incorporate air or if the leavening agents are expired. Beat the butter and sugar until light and fluffy and verify your baking powder’s freshness.
Can I substitute sweetened condensed milk in the frosting?
Sweetened condensed milk is key for the fudge frosting’s texture and sweetness. For a substitute, try evaporated milk with added sugar, but expect a slightly different consistency and flavor.
How do I prevent the marshmallow fluff filling from oozing out?
Leave a small border around the edges when spreading the fluff and chill the cake layers before assembly to help the filling set. Using a firmer homemade marshmallow buttercream can also reduce oozing.
What’s the best way to store leftover cake to maintain freshness?
Keep the cake refrigerated in an airtight container. To preserve moisture, wrap the cake loosely with plastic wrap before placing it in the container. Bring to room temperature before serving.

❓ FAQ
