A Little History
Did you know s’mores have been around for over 100 years? The first written recipe showed up in a Girl Scouts guidebook in the 1920s. Since then, the combination of marshmallows, chocolate, and graham crackers has become an American camping classic. This cake is our way of honoring that tradition—with a delicious, modern twist!

- 8-inch springform pan (or a regular pan lined with plastic wrap)

Step-by-Step Instructions
1. Bake the Chocolate Cake
Preheat your oven to 350°F and prepare two 8-inch cake pans by greasing them and lining them with parchment paper. In a large mixing bowl, whisk together the dry ingredients: flour, sugar, cocoa powder, baking soda, and salt. Once combined, add the egg, buttermilk, vegetable oil, and vanilla extract. Stir until the batter is smooth and free of lumps. Now, carefully pour in the boiling water while continuing to mix. Don’t worry if the batter seems thin; that’s exactly as it should be! Divide the batter evenly between the two pans and bake for 25–30 minutes, or until a toothpick inserted into the center comes out with just a few moist crumbs. Once done, let the cakes cool completely on a wire rack before moving on to assembly.
2. Prepare the Marshmallow Ice Cream
Start by beating the cream cheese and sugar in a large bowl until the texture is nice and smooth. Add in the milk and vanilla extract, mixing until everything is well blended. In another bowl, whip the heavy cream and powdered sugar together until stiff peaks form (you’ll know it’s ready when the whipped cream holds its shape when you lift the whisk). To lighten the cream cheese mixture, fold in about a third of the whipped cream first, then gently fold in the remaining whipped cream. Be careful not to overwork the mixture to keep it fluffy. Finally, stir in the crumbled graham crackers and swirl the marshmallow fluff into the mixture. Be gentle here—you want visible streaks of marshmallow for that perfect gooey texture.
3. Assemble the Ice Cream Cake
Now comes the fun part: assembling the layers! Start by lining a springform pan with parchment paper, leaving the edges of the paper sticking out so you can easily remove the cake later. Use a serrated knife to trim the domes off the cooled cakes so they’re flat and even. Place one cake layer at the bottom of the pan.
For the fudge layer, heat heavy cream in the microwave until it’s hot (but not boiling) and pour it over the chocolate chips and corn syrup. Let the mixture sit for about 3–5 minutes, then whisk it until smooth and glossy. Spread half of this fudge over the cake layer, then sprinkle about half of the mini marshmallows on top. Gently spoon half of the marshmallow ice cream mixture over this and smooth it out evenly.
Repeat the process with the second cake layer. Place it over the ice cream, then add the remaining fudge, marshmallows, and ice cream. Smooth the top layer as much as possible. Cover the pan tightly and freeze the entire cake for at least 6–8 hours, or until it’s completely firm.
4. Decorate the Cake
Once the cake is frozen and set, it’s time to make it look as good as it tastes! In a mixing bowl, whip the heavy cream, powdered sugar, cocoa powder, and vanilla extract together until stiff peaks form. Remove the cake from the freezer and frost it evenly with the whipped cream. Press crumbled graham crackers into the sides of the cake for a bit of texture and crunch, then drizzle chocolate sauce over the top for a dramatic finish.
For the final touch, decorate with whole or halved marshmallows. If you have a kitchen torch, lightly toast the marshmallows for that authentic campfire vibe. And just like that, your S’mores Ice Cream Cake is ready to impress!
