Cake
- ¾ cup Dutch process cocoa powder (sifted)
- 1 cup boiling water
- 1¾ cups all purpose flour
- 1½ cups granulated sugar
- 2½ teaspoons baking powder
- ¾ teaspoon salt
- 2 large eggs (room temperature)
- ¾ cup whole milk
- ½ cup vegetable oil
- 1¾ teaspoons vanilla extract
Marshmallow Filling
- 2 large egg whites
- ⅔ cup granulated sugar
- 8 teaspoons water
Coating
- 4 cups melted or tempered chocolate
- Prepare the oven and pans: Preheat your oven to 350℉ and spray your baking molds with baking spray to ensure the cakes don’t stick.
- Mix cocoa and water: In a small bowl, whisk together the sifted Dutch process cocoa powder and boiling water until smooth and set aside to cool slightly.
- Combine dry ingredients: In a large bowl, whisk together the all-purpose flour, granulated sugar, baking powder, and salt until fully incorporated.
- Add wet ingredients: To the dry ingredients, add the eggs, whole milk, vegetable oil, and vanilla extract. Whisk everything together until the batter is smooth.
- Incorporate chocolate cocoa mixture: Stir the cocoa and boiling water mixture into the batter, combining fully but gently.
- Fill molds and bake: Spoon the batter into the prepared molds, filling each about two-thirds full. Place in the preheated oven and bake for 18-20 minutes or until a toothpick inserted into the center comes out clean.
- Make marshmallow filling – beat egg whites: While the cakes bake, beat the egg whites in a clean bowl until they reach stiff peaks, indicating they hold their shape firmly.
- Prepare sugar syrup: In a small saucepan, combine the granulated sugar and water. Cook over medium-low heat, stirring just until the sugar dissolves.
- Brush down pot sides: Stop stirring and use a pastry brush dipped in water to brush down the sides of the pot to prevent sugar crystals from forming.
- Cook syrup to soft-ball stage: Continue cooking the syrup without stirring until it reaches 246℉-250℉ on a candy thermometer, the soft-ball stage.
- Combine syrup with egg whites: With the mixer running on low, slowly pour the hot sugar syrup into the beaten egg whites in a thin stream, allowing it to incorporate gradually.
- Beat until cool and fluffy: Continue beating the mixture until it cools down and forms a thick, glossy marshmallow filling.
- Level and core cakes: Once the cakes are cool, level their tops with a knife. Using a cupcake corer or spoon, remove the center from each cake to create space for the filling.
- Fill cakes: Transfer the marshmallow filling into a piping bag and pipe it into each cored cavity inside the cakes.
- Replace cake tops: Place the cut-out lids back onto each filled cake, gently pressing to secure the filling inside.
- Dip cake bottoms: Dip the bottom of each filled cake into the melted or tempered chocolate to create a smooth chocolate base.
- Set dipped cakes: Place the dipped cakes on a parchment-lined sheet pan and allow the chocolate to set completely.
- Chocolate coat the cakes: Place the cakes onto a wire cooling rack and spoon melted chocolate over the tops and sides, fully coating each cake in a glossy chocolate shell. Allow the coating to set before serving.
Notes
- Ensure eggs are at room temperature for better incorporation and a smoother batter.
- Using Dutch process cocoa gives deeper chocolate flavor; sift it to avoid lumps.
- Be careful when cooking sugar syrup to the correct temperature for a stable marshmallow filling.
- Tempering the chocolate for coating ensures a shiny finish and crisp snap; alternatively, use high-quality melted chocolate.
- Allow each chocolate coat to fully set before adding the next layer to avoid melting or smudging.
- Store the finished cakes in an airtight container at room temperature or in the refrigerator if your kitchen is warm.
