2 ounces (60 grams) unsweetened chocolate, chopped
2 tablespoons (15 grams) unsweetenedcocoa powder (not Dutch-processed)
1/2 cup (120 ml) boiling water
1 cup plus 2 tablespoons (150 grams) all purpose flour
1 teaspoon baking powder
1/2 teaspoon baking soda
1/4 teaspoon salt
1/2 cup (113 grams) unsalted butter, room temperature
1 cup (200 grams) granulated white sugar
2 large eggs
1 teaspoon pure vanilla extract
1/2 cup (120 ml) milk
Preheat oven to 350 degrees F (177 degrees C) and place rack in center of oven. Line 15 muffin cups with paper liners.
In a stainless steel or heatproof bowl place the chopped unsweetened chocolate and cocoa powder.
Pour the boiling water over the chocolate and cocoa powder and stir until they have melted. Set aside to cool while you make the batter.
In a separate bowl, whisk to combine, the flour, baking powder, baking soda, and salt.
In the bowl of your electric mixer, or with a hand mixer, beat the butter until smooth and creamy.
Gradually add the sugar and continue beating until the mixture is fluffy.
Add the eggs, one at a time, beating well after each addition. Scrape down the sides of the bowl as needed.
Add the vanilla extract and melted chocolate mixture and beat to combine.
Add the milk and flour mixtures in three additions, beginning and ending with the flour mixture. Beat only until the ingredients are incorporated.
Evenly divide the batter among the muffin cups, and bake for about 18 – 23 minutes or until a toothpick inserted in the center of a cupcake comes out clean.
Remove from oven and place on a wire rack to cool.
Place all ingredients except the vanilla essence into a bowl which you can place over a pot of simmering water.
Whisk the egg white mixture constantly over simmering water until the sugar dissolves and the mixture is hot to the touch.
It takes around 5 minutes.
Pour the mixture into a bigger bowl and beat with an electric mixer for 3 minutes. Add the vanilla while beating. After 3 minutes, the mixture will be lovely and fluffy.
Pipe (I used a Wilton 1M star tip) or spread frosting on each cupcake.
