Yield: 16 Cupcakes
Total Time: 55 minutes
Prep: 20-25 minutes
Bake Time: 20-30 minutes
Preheat the oven to 350F, spray the tops of 2 cupcake tins and trays with 16 liners (evenly spaced out because you will have empty spots).
Separate Egg Whites and Yolks. Be careful to not get any yolk in the whites, or the whites will not whip properly. The best way is to crack the egg over a separate small bowl and then transfer the white to your mixing bowl and the yolk to another bowl. It creates more dirty dishes, but prevents any yolks from getting into your whites.
Sift the Cake Flour, Cocoa Powder, Espresso Powder and 1/2 cup plus 4 tablespoons Sugar into a medium bowl and set aside.
In the bowl of your stand mixer, with the whip attachment, whip the Egg Whites, Salt, Cream of Tartar and Vanilla on high, until soft peaks form. While the mixer is still on high, gradually add in the remaining Sugar, a little at a time, and whip until stiff, glossy peaks form (2-3 minutes).
Gently fold the dry ingredients into the egg whites in three additions, making sure not to deflate the egg whites too much.
Fill each cupcake liner high with batter - two ice cream scoops full.
Dust each cupcake with Confectioners Sugar and sprinkle the tops with a few mini Chocolate Chips.
Bake for 20-30 minutes - depending on your oven - until the tops are puffed and dry.
Keep the cupcakes in the tin for an hour to cool and ensure they keep their shape. After one hour, gently remove the cupcakes and enjoy! They can be stored in an airtight container for up to 2 days - although I don't think they will last that long, they are too delicious!
