How to Add the Peanut Butter Filling

Once the cupcakes are finished baking, you will need to scoop out a small amount from the middle of each cupcake in order to add the melted peanut butter. I've found that using a small cookie dough scooper works perfectly for this!

Peanut Butter Buttercream Frosting Tips

Making a homemade buttercream frosting isn't always as simple as one thinks – especially if you've never made it before. I remember the first time I tried to make it, the frosting came out way too thick and wasn't as smooth as it should've been. So below I've included some tips on both making frosting and icing cupcakes that I've learned along the way. Hopefully, these tips will help you as well!

  1. When preparing the buttercream frosting, make sure the butter is soft, or it won't easily incorporate into the buttercream.
  2. While mixing the frosting, if powdered sugar pebbles form, simply add in little more heavy cream  (up to 1 to 2 additional tablespoons).
  3. If the frosting is too thin add in up to an additional ½ C powder sugar.
  4. No pastry bag or tip? Just fill a zip-lock bag with buttercream and then snip 1/2 inch off corner.
  5. Do not start frosting until the cupcakes are completely cooled.

Can These Cupcakes Be Stored?

Yes! If you are simply storing these for the next day, place them in a container then store them in a cool, dry place as this will help ensure the buttercream frosting stays creamy and soft. For longer keeping, cover and store the cupcakes in the refrigerator for up to 5 days.

Cupcake Ingredients

  • 1 cup unsalted sweet cream butter softened
  • 3 cups sugar
  • 3 cups flour
  • 1 cup cocoa
  • 2 tsp baking soda
  • ½ tsp sea salt
  • 4 eggs
  • 1 tsp vanilla
  • 1 cup buttermilk
  • 1 cup water
  • 1 cup peanut butter for the filling after cupcakes are made

Frosting Ingredients

  • 1 cup unsalted sweet cream butter unsalted
  • 3 cups powdered sugar
  • ½ cups peanut butter
  • 5 tbsp heavy whipping cream
  • 1 tsp vanilla
  • chocolate syrup for drizzling


Cupcake Instructions

  • Preheat oven to 350 degrees and fill a cupcake pan with cupcake liners.
  • In a large bowl, cream together the butter and sugar and cream until completely mixed.
  • Add in the eggs, one at a time, beating to combine.
  • Add in the vanilla.
  • In another large bowl, combine all of the dry ingredients.
  • In a third bowl, combine the milk and water.

  • Let cupcakes cool on wire racks before frosting.

Instructions To Make the Frosting

Putting It All Together

  • Add the remaining cup of peanut butter to a small, microwave-safe bowl, and put microwave for 1 minute. Stir.
