Ingredients
Scale
- 1 cup plus 1 tbsp (150g) all-purpose flour
- ⅓ cup (28g) cocoa powder
- ½ teaspoon baking powder
- ½ teaspoon baking soda
- ¾ cup (150g) granulated sugar
- ¼ teaspoon salt
- 1 large egg
- ¼ cup (60ml) oil
- ⅓ cup (80ml) whole milk
- 1 teaspoon (5ml) pure vanilla extract
- ½ cup (120ml) hot coffee
- 5 oz (142g) marshmallows
- 3 tablespoon (42g) unsalted butter
- 1 cup (237ml) 35% heavy whipping cream
- 5 oz (142g) semisweet dark chocolate
- ⅓ cup plus 1 tbsp (95ml) 35% heavy whipping cream
- 1 teaspoon (7ml) honey or corn syrup
Instructions
- Preheat the oven to 325°F and prepare an 8×8-inch baking pan with parchment paper.
- Sift the flour, cocoa powder, baking powder, and baking soda into a medium bowl; then mix in the sugar and salt.
- Create a well in the dry ingredients and add oil, egg, milk, and vanilla, whisking until combined.
- Incorporate the hot coffee gradually into the batter until smooth; it will be thin.
- Spread the batter evenly into the pan and bake for 20-25 minutes, until a skewer comes out clean. Cool completely in the pan and trim the top if needed.
- For the filling, melt butter with marshmallows in a microwave, stirring until smooth; cool slightly.
- Whip cold cream until stiff peaks form, then mix a portion into the marshmallow mixture and fold in the remainder gently.
- Slice the cooled cake horizontally in half, spread most of the marshmallow filling on the bottom layer, and place the top layer on.
- Prepare the ganache by heating cream and whisking it over chopped chocolate until smooth. Pour it over the cake and let it set.
- Pipe the reserved marshmallow filling on top in decorative patterns before slicing and serving.
