Ingredients

3/4 cup unsweetened cocoa powder
1 1/2 cups all-purpose flour
1 1/2 cups sugar
1 1/2 teaspoons baking soda
3/4 teaspoon baking powder
3/4 teaspoon salt
2 large eggs
3/4 cup warm water
3/4 cup buttermilk
3 tablespoons safflower oil
1 teaspoon pure vanilla extract
2 1/2 cups sugar
10 large egg whites
4 cups (8 sticks or 2 pounds) unsalted butter, cut into pieces
2 teaspoons pure vanilla extract

Steps:

One-Bowl Chocolate Cupcakes: Preheat oven to 350 degrees. Line standard muffin tins with paper liners. Sift cocoa powder, flour, sugar, baking soda, baking powder, and salt into a large bowl. Add eggs, warm water, buttermilk, oil, and vanilla, and mix until smooth.
Divide batter among muffin cups, filling each 2/3 full. Bake until tops spring back when touched, about 20 minutes. Transfer cupcakes to wire racks, and let cool. Cupcakes will keep, covered, for up to 3 days.
Swiss Meringue Buttercream: Place sugar and egg whites in the heat-proof bowl of an electric mixer. Set bowl over a pan of gently simmering water, and whisk until sugar has dissolved and egg whites are hot to the touch, about 3 minutes. Test by rubbing the mixture between your fingers; it should feel completely smooth.
Transfer bowl to mixer stand. Using the whisk attachment, beat on high speed until mixture has cooled completely and formed stiff and glossy peaks, about 10 minutes.
Add the butter, one piece at a time, and beat until incorporated after each addition. Don't worry if the buttercream appears curdled after all the butter has been added; it will become smooth again with continued beating. Add vanilla, and beat just until combined.
Switch to the paddle attachment, and beat on the lowest speed to eliminate any air pockets, about 5 minutes. If using buttercream within several hours, cover bowl with plastic wrap, and set aside at room temperature in a cool environment. Or transfer to an airtight container, and store in the refrigerator, up to 3 days. Before using, bring buttercream to room temperature, and beat on the lowest speed with the paddle attachment until smooth, about 5 minutes.
To decorate, use a medium round tip (such as Ateco #12) to pipe a mound of buttercream in the center of cupcake, then outline and pipe a brain design over it.
