Ingredients
Chocolate Ganache
- Three 4-ounce bars (339g) semi-sweet or milk chocolate, finely chopped
- 1 and 1/2 cups (360ml) heavy cream
Marshmallow Meringue
- 6 egg whites, at room temperature
- 1 and 1/2 cups (300g) granulated sugar
- 3/4 teaspoon cream of tartar
- 1 teaspoon pure vanilla extract
Assembly
- 30-36 full-sheet graham crackers (a little over 1 standard box)
Instructions
- Prepare the pan: Line an 8-inch or 9-inch square baking pan with parchment paper, leaving an overhang on the sides to help lift the cake out for easy cutting and serving.
- Make the ganache: Place the chopped chocolate into a bowl. Heat the heavy cream in a small saucepan just until it begins to gently simmer—avoid boiling. Pour the hot cream over the chocolate and let it sit for 2-3 minutes to soften the chocolate. Stir slowly until fully combined and smooth. Cover and refrigerate while preparing the meringue. Ganache can be made up to 3 days ahead and refrigerated.
- Make the marshmallow meringue: In a heatproof bowl, combine egg whites, sugar, and cream of tartar. Place this bowl over a saucepan of simmering water (double boiler), making sure the bowl doesn’t touch the water. Whisk constantly until the sugar dissolves and the mixture is warm and slightly thinned, about 4 minutes. Add vanilla extract. Using a mixer with a whisk attachment, beat on high speed for 5-6 minutes until stiff, glossy peaks form. Remove 1 heaping cup of meringue for the topping; cover and refrigerate it up to 2 days.
- Assemble the cake: Spread a super thin, uneven layer of marshmallow meringue on the bottom of the parchment-lined pan to help the graham crackers stick. Layer graham crackers, then marshmallow meringue, then graham crackers, followed by chocolate ganache, then graham crackers, marshmallow meringue, graham crackers, chocolate ganache, graham crackers, marshmallow meringue, graham crackers, and finally a last layer of chocolate ganache on top—totaling 6 graham cracker layers, 4 marshmallow meringue layers, and 3 chocolate ganache layers.
- Chill the cake: Cover the cake tightly and refrigerate for at least 12 hours or up to 2 days to allow the layers to set and meld flavors.
- Prepare the topping: Remove the reserved marshmallow meringue from the fridge; if deflated, lightly whip it with a whisk or fork to restore fluffiness.
- Finish and serve: Lift the cake out of the pan using the parchment overhang. Peel off the parchment paper or leave it if you plan to torch the top carefully. Spread the reserved marshmallow meringue over the cake top, creating peaks and swirls with a spoon. Serve immediately as is, torch with a kitchen torch before serving, or refrigerate loosely covered for up to 1 hour before torching and serving.
- Storage: Store leftovers covered in the refrigerator or freezer for up to 2 days. Note that the marshmallow topping may begin to wilt during storage.
Notes
- Use full-sheet graham crackers for proper layering and easier assembly.
- Ganache can be prepared and refrigerated up to 3 days in advance for convenience.
- Reserve some marshmallow meringue to use as the topping; it improves presentation and texture.
- If you don’t have a kitchen torch, serve the cake without torching—still delicious!
- Allow at least 12 hours of chilling for the cake layers to set and meld flavors properly.
- Be cautious when torching the marshmallow topping to avoid igniting the parchment paper.
