Ingredients

For the chocolate cupcakes:

  • 160 g (1 ⅓ cups) all-purpose flour
  • 236 g (1 cup + 3 tbsp) granulated sugar
  • 42 g (½ cup) dutch process cocoa powder
  • 1 teaspoon baking powder
  • ½ teaspoon kosher salt
  • 150 g ( cup) whole milk, room temp
  • 100 g (½ cup) neutral oil
  • 2 eggs, room temp
  • 1 teaspoon vanilla extract
  • 75 g ( cup) freshly brewed hot coffee

For the peanut butter frosting:

  • 113 g (8 tablespoon) unsalted butter, room temp
  • ½ teaspoon salt
  • 405 g (1 ½ cups) peanut butter, thick & creamy
  • 170 g (1 ½ cups) powdered sugar, sifted
  • ½ tablespoon heavy cream
  • Large peanut butter cups, for topping

Instructions

For the chocolate cupcakes:

  • Preheat the oven to 325 degrees F. Add parchment cups to a cupcake pan.
  • In a medium bowl, whisk together the flour, sugar, cocoa powder, baking powder, and salt. Set aside.
  • In a large bowl, whisk together the milk, oil, eggs, and vanilla.
  • Add the dry ingredients to the wet and whisk until just combined.
  • Lastly, whisk in the hot coffee until fully combined.
  • Transfer the batter to the cupcake pan, filling each cup about ¾ full.
  • Bake the cupcakes for about 20 minutes or until a toothpick inserted comes out clean. Allow the cupcakes to cool in the pan for a few minutes before transferring to a wire rack to cool completely.

For the peanut butter frosting:

  • In the bowl of a stand mixer fitted with a paddle attachment, beat the butter and salt on high speed until smooth.
  • Add the peanut butter and mix until fully combined.
  • Slowly add the sifted powdered sugar and mix on low speed until fully combined.
  • Lastly, add the heavy cream and continue beating on low speed until no more lumps or pockets of air remain and the frosting is smooth.
  • Decorate the cupcakes as desired. Top each with half of a peanut butter cup, and enjoy!

Notes

  • Use a thick & creamy peanut butter. I recommend only using a thick, creamy peanut butter like Jif or Skippy.
