Ingredients
Scale
- 1 3/4 cups (220 g) all-purpose flour
- 3/4 cup (75 g) unsweetened cocoa powder
- 2 cups (400 g) granulated sugar
- 1 1/2 tsp baking powder
- 1 1/2 tsp baking soda
- 1 tsp fine sea salt
- 2 large eggs, room temperature
- 1 cup (240 ml) whole milk, room temperature
- 1/2 cup (120 ml) neutral oil
- 2 tsp vanilla extract
- 1 cup (240 ml) hot brewed coffee
- 2 cups (200 g) graham cracker crumbs
- 6 tbsp (85 g) unsalted butter, melted
- 2 tbsp light brown sugar
- 12 oz (340 g) marshmallow fluff
- 8 oz (225 g) semi-sweet chocolate, finely chopped
- 1 cup (240 ml) heavy cream
- 2 tbsp light corn syrup
- Extra graham crumbs for garnish
- Mini marshmallows for toasting
- Sea salt flakes (optional)
Instructions
- Preheat the oven to 350°F (175°C). Grease three 8-inch cake pans, line bottoms with parchment, and grease again.
- Whisk flour, cocoa powder, sugar, baking powder, baking soda, and salt in a large bowl. In another bowl, combine eggs, milk, oil, and vanilla.
- Add wet ingredients to dry, then gradually stir in hot coffee until just combined.
- Divide batter evenly between pans and bake for 22–28 minutes. Cool in pans for 10 minutes, then invert onto cooling racks.
- Pulse graham crackers into fine crumbs and combine with melted butter and brown sugar.
- Press two-thirds of the crumbs into two 8-inch rounds lined with parchment and chill until firm.
- Heat cream until simmering, then pour over chopped chocolate. Let sit and whisk until smooth.
- Toast marshmallows if using large ones, or mix fluff until spreadable.
- Assemble the cake by layering chocolate cake, ganache, marshmallow, and graham cracker discs.
- Chill briefly between layers and finish with additional marshmallow on top if desired.
Notes
For optimal flavor, use high-quality chocolate and allow cake layers to cool completely before assembly.
