For the Toasted Topping

• 2 cups mini marshmallows

Instructions

Step 1: Prepare the Cake Layers

1. Preheat your oven to 350°F (175°C) and grease three 8-inch round cake pans.
2. In a large bowl, whisk together flour, cocoa powder, sugar, baking powder, baking soda, and salt.
3. Add eggs, milk, oil, and vanilla extract. Mix until smooth and well combined.
4. Slowly stir in hot coffee until the batter is thin but evenly blended.
5. Divide batter evenly between pans and bake for 25–30 minutes.
6. Allow cakes to cool completely on a wire rack before assembling.

Step 2: Make the Graham Cracker Crunch

1. Combine crushed graham crackers, melted butter, and brown sugar in a bowl.
2. Spread the mixture on a baking sheet and bake for 8–10 minutes at 350°F.
3. Let it cool completely—it will crisp up as it cools.

Step 3: Prepare the Marshmallow Filling

1. Beat softened butter until creamy and smooth.
2. Gradually add powdered sugar, mixing well after each addition.
3. Fold in marshmallow fluff, vanilla extract, and a pinch of salt.
4. Beat until light, fluffy, and spreadable.

Step 4: Make the Chocolate Ganache

1. Heat heavy cream until just simmering (do not boil).
2. Pour over chopped chocolate and let sit for 2–3 minutes.
3. Stir until smooth and glossy.
4. Allow to cool slightly before using.

Step 5: Assemble the Cake

1. Place one cake layer on a serving plate.
2. Spread a generous layer of marshmallow filling.
3. Sprinkle graham cracker crunch evenly over the filling.
4. Add a drizzle of chocolate ganache.
5. Repeat with the second layer.
6. Top with the final cake layer and lightly frost the outside with remaining marshmallow frosting.

Step 6: Add the Toasted Finish

1. Pile mini marshmallows on top of the cake.
2. Use a kitchen torch to toast them until golden brown (or broil briefly in the oven).
3. Drizzle with chocolate ganache and sprinkle graham crumbs.

Tips for the Perfect S’mores Cake

Use Coffee for Deeper Flavor

Adding hot coffee enhances the chocolate flavor without making the cake taste like coffee. It’s a secret ingredient that elevates the entire dessert.

Toast Carefully

When torching marshmallows, move the flame constantly to avoid burning. You want a golden, slightly crispy finish—not charred.

Chill Before Slicing

Refrigerate the assembled cake for 30 minutes before slicing. This helps the layers set and makes cleaner cuts.

Don’t Skip the Crunch Layer

The graham cracker crunch is essential—it adds texture and authentic s’mores flavor that sets this cake apart.

Variations to Try

Peanut Butter S’mores Cake

Add a layer of peanut butter frosting or drizzle peanut butter between layers for a nutty twist.

Salted Caramel Version

Drizzle salted caramel sauce between layers and over the top for a rich, sweet-salty contrast.

Mini S’mores Cakes

Use the same recipe to make individual mini cakes or cupcakes for parties and gatherings.

Dark Chocolate Upgrade

Swap semi-sweet chocolate with dark chocolate for a more intense flavor profile.
