Peanut Butter Caramel Cupcakes

Peanut butter cupcakes stuffed with caramel, topped with peanut butter buttercream and a drizzle of caramel.



  • ½ cup smooth peanut butter (135 grams)
  • 1 cup granulated sugar (200 grams)
  • 1 ½ cups all-purpose flour (200 grams)
  • 1 ½ teaspoon baking powder
  • ½ teaspoon baking soda
  • ¼ teaspoon salt
  • ¾ cup buttermilk (175 ml)
  • 2 large eggs
  • 1 teaspoon vanilla extract


  • 4 ounces cream cheese , at room temperature (113 grams)
  • ¼ cup unsalted butter , at room temperature (56 grams)
  • cup smooth peanut butter (90 grams)
  • 2 cups powdered sugar , sifted (450 grams)
  • ½ teaspoon vanilla extract
  • Pinch of salt
  • 1-2 tablespoons milk or cream

For assembly:

  • 1 cup caramel , see Note
  • ½ cup peanuts (70 grams)


To make the cake:

  • Preheat oven to 350° F. Line a muffin pan with cupcake liners or grease with butter or nonstick cooking spray.
  • In the bowl of a stand mixer fitted with a paddle attachment, or in a large bowl with a hand-held mixer, beat the peanut butter and sugar on high speed until light and fluffy, and the mixture sticks to the sides of the bowl. This should take about 4-5 minutes.
  • In a separate bowl, combine the flour, baking powder, baking soda, and salt. Whisk together the buttermilk, eggs and vanilla extract in a third bowl. Alternately add the wet and dry ingredients to the mixer in 3 additions, starting and ending with the dry ingredients.
  • Spoon the batter into the prepared cupcake liners, filling each only half way. Bake until tops spring back when touched and a toothpick inserted into the center comes out clean, 14-16 minutes. Let cool completely.

To make the frosting:

  • Beat the cream cheese, butter, peanut butter, powdered sugar, vanilla and salt together until smooth. Add enough milk or cream to get a spreadable consistency. Beat on high another 1-2 minutes until light and creamy.

To assemble the cupcakes:

  • Use a small knife to cut a small well 1 inch deep into the tops of each cupcake. Spoon about 1 teaspoon of the caramel into the well, it should not overflow.
  • Top each cupcake with the frosting, either with a knife or with a piping bag and tip. Drizzle the cupcakes with more caramel and top with peanuts.
  • Store cupcakes in the refrigerator.
Note: I used store-bought caramel ice cream topping, but you can also make your own.
