Ingredients

  • Cupcakes:
  • 1 cup granulated sugar
  • 1 cup brown sugar - not packed
  • 1 ¾ cup all-purpose flour
  • ¾ cup unsweetened cocoa powder
  • 1 ½ teaspoons baking soda
  • 1 ½ teaspoon baking powder
  • ½ teaspoon salt
  • 2 large eggs room temperature
  • 1 cup milk room temperature
  • ½ cup vegetable or canola oil
  • 2 teaspoons vanilla extract
  • ¾ cup boiling water
  • Peanut Butter Frosting:
  • ½ cup 1 stick unsalted butter, softened
  • 1 cup peanut butter
  • 2-3 tablespoons milk
  • 3 cups powdered sugar

Instructions

  • Cupcakes:
  • Preheat oven to 350 degrees F
  • Fill cupcake pan with liners
  • In a medium bowl, whisk together sugar, brown sugar, flour, cocoa powder, baking soda, baking powder and salt
  • In a large bowl beat eggs, milk, oil and vanilla extract until well combined
  • Add dry ingredients to wet ingredients and mix until well combined and no lumps are left. Scrape down sides of the bowl occasionally
  • Add boiling water and slowly beat until combined. Batter will be thin.
  • Fill cupcake liners about ½ full - don’t overfill
  • Bake for 12-15 minutes or until a toothpick inserted in the center comes out clean
  • Remove from oven and cool on wire rack
  • Peanut Butter Frosting:
  • In a medium bowl, cream together butter and peanut butter until smooth and fluffy
  • Gradually add powdered sugar, alternating with milk, beating after each additional until desired consistency
  • Frost cupcakes and garnish with candy or sprinkles if desired
  • Store leftovers in airtight container

Notes

These are very moist cupcakes with a great chocolate flavor.
Only filling ½ full is important, as they will quickly overflow the liners.
