Ingredients
  

For the cupcakes

  • 2/3 cup unsweetened cocoa powder
  • 1 teaspoon baking soda
  • 3/4 teaspoon salt
  • 1 cup boiling water
  • 1 3/4 cups granulated sugar
  • 1/2 cup unsalted butter melted (1 stick)
  • 1/3 cup vegetable oil
  • 1 teaspoon vanilla extract
  • 2 large eggs
  • 2 egg yolks
  • 1/2 cup whole milk
  • 1 3/4 cup all-purpose flour

For the chocolate buttercream frosting

  • 1 cup butter softened (2 sticks)
  • 1/2 cup cocoa powder unsweetened
  • 1 tablespoon milk for consistency
  • 2 teaspoons vanilla extract
  • 3 cups powdered sugar
  • 1 pinch salt for balance

Instructions
 

Cupcakes

  • Gather your tools and ingredients. Set out all of your butter to soften to room temp. Preheat oven to 350°F. Line 24 wells of muffin pans with cupcake liners or prep pan with nonstick spray; set aside.
  • You'll be boiling 1 cup of water, so get out a microwave safe measuring cup (like Pyrex) or an electric tea kettle for this. Also: The batter uses 1/2 c melted butter, and you can use the same microwave-safe measuring cup for this effort as well.
  • In a medium mixing bowl, whisk together the cocoa powder, baking soda, and salt. Carefully pour in the boiling water and whisk until well blended. Set the bloomed cocoa mixture aside.
  • In a large mixing bowl, combine the sugar, melted butter, vegetable oil, and vanilla. Using an electric mixer or a whisk, beat in the eggs and egg yolks one at a time.
  • Add the cocoa mixture and the milk, stirring just until combined.
  • Add the flour and stir the batter with a wooden spoon or whisk, just until the flour is incorporated. Don't overmix; it can affect the tender crumb.
  • Batter will be thin. Spoon the batter into the prepared pan, filling each cupcake about 2/3 full.
  • Bake at 350F for 18-20 mins, until a toothpick or tip of a butterknife inserted into the center comes out clean.
  • Leave the cupcakes in the pan for 5 mins, then remove to a plate or a wire rack to finish cooling completely. This is the patience we were trained for as children. We can do this.

Chocolate buttercream frosting

  • While the cupcakes cool: In a large mixing bowl, use an electric mixer to beat just the butter until smooth and light colored, about 45 seconds.
  • To the beaten butter, add cocoa powder, milk, and vanilla extract, then beat until creamy and incorporated.
  • Add the powdered sugar 1/2 cup or so at a time.
  • Spread or pipe the frosting onto the completely cooled cupcakes. If you want to save the frosting, add to a container with an airtight lid; it should be good in the fridge about two weeks if kept cold. Bring to room temp and stir well before topping cupcakes.
  • Note about the decoration on the cupcakes shown: The frosting pattern uses a petal or ruffle tip to achieve this look. Standard is a #104 Petal Tip (shown) or larger is #125 Petal Tip for wider, more dramatic ribbons.

Notes

Freeze unfrosted cupcakes for up to 3 months. Store leftover cupcakes in an airtight container for up to 5 days; refrigerate, then bring to room temperature before serving.
