Chocolate Peanut Butter Cupcakes with Chocolate Frosting

Last Saturday was a special anniversary.  An anniversary worthy of these Chocolate Peanut Butter Cupcakes made with chocolate cake, filled with peanut butter and topped with a fluffy chocolate frosting.  These cupcakes are light, decadent and perfect to celebrate this milestone anniversary.  This anniversary in question, or blog-o-versary as some call it, marks the 1 year anniversary of Alida’s Kitchen!

The chocolate/peanut butter combination is always a winner for any celebration.  I doubled the amount of peanut butter filling from the original recipe, which resulted in a generous amount of peanut butter.  It had a good peanut butter to chocolate ratio, which is key.  I used my go-to chocolate frosting, which is a classic and pipes really nicely. 

These Chocolate Peanut Butter Cupcakes were super easy to make and the result was the perfect treat to celebrate the 1 year blog-o-versary of Alida’s Kitchen.  I want to thank you all so much for visiting and for cooking and baking with me this past year! 

Chocolate Peanut Butter Cupcakes with Chocolate Frosting
Yields 24 cupcakes

6 ounces Neufchatel cream cheese (the 1/3 less fat kind), at room temperature
1/2 cup peanut butter
1/4 cup granulated sugar
2 tablespoons skim milk

2 cups sugar
1 3/4 cups all-purpose flour
1/2 cup unsweetened cocoa powder
1 1/2 teaspoons baking powder
1 teaspoon salt
1/4 teaspoon baking soda
2 eggs
1 cup water
1 cup skim milk
1/2 cup canola oil
2 teaspoons vanilla extract

1/2 cup (1 stick) butter

2/3 cup unsweetened cocoa powder
3 cups powdered sugar
1/3 cup skim milk
1 teaspoon vanilla extract


  1. Make Filling:  In a small bowl, beat cream cheese, peanut butter, sugar, and milk until combined.  Set aside.
  2. Make Cake: Preheat oven to 350 degrees.  Line 24 muffin cups with paper liners and set aside.
  3. In a large bowl, whisk sugar, flour, cocoa, baking powder, salt and baking soda.
  4. In a separate bowl, whisk the eggs, water, milk, oil and vanilla.  Fold into dry ingredients until just moistened.  (note: batter will be thin).
  5. Fill prepared muffin cups half full with batter. 
  6. Divide filling evenly amongst the 24 cups, dropping spoonfuls of filling in the center of each cup (Tip: using a scale is handy for measuring and even distribution.  If you don’t have a scale, The filling amounts to approx. a generous rounded tablespoon per cupcake). 
  7. Cover each cup with remaining batter.
  8. Bake for 20 to 25 minutes, or until a toothpick inserted into cake comes out clean.  Cool for 10 minutes in the pan and the move cupcakes to a wire rack to cool completely.
  9. Once cooled, frost with chocolate frosting and decorate as desired.  
  10. Make Frosting:  Melt the butter. Whisk in the cocoa powder, whisking until smooth.
  11. Stir in vanilla and alternately add powdered sugar and milk, using a hand mixer (or stand mixer) to beat to spreading consistency. Add small amount additional milk, if needed.
