  • 1.5 cups all-purpose flour
  • 1.5 cups granulated sugar
  • 0.75 cup unsweetened cocoa powder
  • 1.5 tsp baking powder
  • 1.5 tsp baking soda
  • 1 tsp salt

Wet Ingredients for Cupcakes

  • 2 large eggs
  • 0.75 cup buttermilk
  • 0.25 cup vegetable oil
  • 2 tsp pure vanilla extract
  • 0.75 cup hot water
  • 0.5 cup dark chocolate chips rich and melted

Peanut Butter Buttercream Frosting

  • 1 cup unsalted butter softened
  • 1 cup creamy peanut butter
  • 4 cups powdered sugar
  • 0.25 cup whole milk
  • 2 tsp pure vanilla extract

Instructions

Prepare and Bake Cupcakes

  • Preheat oven to 350°F (175°C). Line a 12-cup muffin tin with paper liners.
  • In a large bowl, sift together flour, sugar, cocoa powder, baking powder, baking soda, and salt.
  • In a separate bowl, whisk the eggs, buttermilk, vegetable oil, and vanilla extract until combined.
  • Slowly add the wet ingredients into the dry ingredients, mixing gently until just combined.
  • Carefully stir in the hot water until the batter is smooth and thin.
  • Fold in the dark chocolate chips.
  • Divide the batter evenly among the muffin cups, filling each about two-thirds full.
  • Bake for 20-25 minutes, or until a toothpick inserted in the center comes out clean or with moist crumbs.
  • Remove cupcakes from the oven and allow them to cool completely on a wire rack before frosting.

Prepare Frosting and Assemble

  • In a large mixing bowl, beat the softened butter and creamy peanut butter together until smooth and fluffy.
  • Gradually add powdered sugar, mixing on low speed to prevent sugar clouds, until fully incorporated.
  • Add whole milk and vanilla extract, then increase speed and beat until the frosting is light and spreadable.
  • Frost cooled cupcakes with the peanut butter buttercream using a spatula or piping bag as desired.

Notes

  • Use room temperature butter for the smoothest frosting.
  • Allow cupcakes to cool completely before frosting to prevent melting.
  • Store frosted cupcakes in an airtight container refrigerated for up to 4 days; bring to room temperature before serving.
