Ingredients

Chocolate cupcakes

Peanut butter frosting

  • cup unsalted butter, softened at room temperature
  • 1⅓ cup creamy peanut butter
  • 2 cups powdered sugar
  • 1 tablespoon whole milk (heavy cream also works)

Garnish

  • ¼ cup dark chocolate, melted (optional)
  • ¼ cup salted roasted peanuts, chopped (optional)

Instructions

Chocolate cupcakes

  • Preheat the oven to 340°F (170°C) and line a cupcake tin with liners and set aside.
  • In a large bowl, sift together the sugar, cake flour, all-purpose flour, cocoa powder, instant espresso, salt, baking soda, and baking powder.
  • Add the egg, sour cream, whole milk, warm water, oil, vanilla and stir until just combined.
  • Pour the cupcake batter into a lined cupcake pan about ⅔ of the way up, and bake them for 15 to 18 minutes.
  • Let the cupcakes cool in the pan for a minute before transferring them to a wire rack to cool completely.

Peanut butter frosting

  • In a bowl, cream together the unsalted butter and peanut butter. Beat until pale and fluffy. If it looks too soft, stick it in the fridge for 10 minutes before beating again.
  • Add the sifted powdered sugar a little at a time and beat again. Add the milk if necessary.
  • Pipe or spread the peanut butter frosting onto the cooled chocolate cupcakes and garnish with chopped peanuts and melted chocolate.
