Method
Preparation
- Preheat the oven to 350°F (175°C) and line two baking sheets with parchment or use a silicone mat.
- In a bowl, whisk the sifted Dutch cocoa into the boiling water until smooth and glossy. Allow it to cool slightly.
- In a large bowl, combine flour, 1½ cups granulated sugar, baking powder, and salt, whisking until even.
- In a separate bowl, whisk the eggs, milk, oil, and vanilla until luminous. Stir the wet ingredients into the dry, then fold in the cocoa mixture.
- Drop tablespoon-sized mounds of batter onto the prepared sheet, spaced about 2 inches apart.
- Bake for 9–12 minutes until the tops spring back to the touch and cool completely on a rack.
Filling
- In a clean, dry bowl, whisk the egg whites until foamy. Gradually add the ⅔ cup granulated sugar while whisking until soft peaks form.
- Heat 8 teaspoons of water and sugar in a small saucepan to dissolve; stream this into the whisking egg whites to stabilize the marshmallow.
- Beat until glossy and spreadable, then transfer to a piping bag.
Assembly
- Hollow a shallow well in the flat underside of each cooled cake or sandwich two rounds with marshmallow filling.
- Pipe marshmallow into each cavity and cap with another round.
- Melt or temper chocolate until smooth, then dip each assembled cake into the chocolate and allow excess to drip.
- Place on parchment and allow to set at room temperature or in the refrigerator until firm.
Notes
Serve at room temperature and store in an airtight container. Best consumed within 2 days at room temperature, or refrigerate for up to 5 days.
