Make peanut butter filled chocolate cupcakes with your favorite chocolate cupcakes, a peanut butter fudge filling and homemade chocolate frosting. 

Peanut Butter Filled Chocolate Cupcakes

The classic combination of peanut butter and chocolate is amazing in these peanut butter filled chocolate cupcakes.  Just use your favorite chocolate cupcake – either store bought or homemade. You’ll easily fill it with a thick fudge like peanut butter filling similar to the filling in Chocolate Peanut Butter Cookie Cups. Then top it all off with velvety chocolate frosting. 

There are 3 different parts of these cupcakes: the chocolate cupcake, the peanut butter filling, and the chocolate frosting. A super easy short cut is to order plain chocolate cupcakes from your local grocery store bakery. Then you can make the filling and frosting and call them “homemade.” 

Peanut Butter Filled Chocolate Cupcakes Ingredients:

  • Chocolate cupcakes, baked and cooled
  • Butter, softened
  • Peanut butter
  • Powdered sugar
  • Unsweetened cocoa powder
  • Vanilla
  • Milk

Cupcake Directions:

Apple corer hollowing out a chocolate cupcake

 

Use an apple corer to cut a divot into the center of each cupcake. You want to go about 1/2″ into the cupcake and discard (or snack on later) the cake. If you do not have an apple corer, you can also use a teaspoon to carefully hollow out the middle of the cupcake. When all the cupcakes have been hollowed out, set them aside.

Next, you make the peanut butter filling. In a mixing bowl, beat together the butter, peanut butter and powdered sugar.

You want the mixture to be stiff. It is a lot like a fudge filling. 

Filling a chocolate cupcake with the peanut butter filling

Next, fill the cupcakes with the peanut butter filling. Use a teaspoon size amount of fudge mixture and shape into a cylinder with your fingers. Press the peanut butter filling into cupcake. The fudge filling should be level with the top of the cupcake. Repeat until you have all cupcakes filled.

Topping the chocolate cupcakes with peanut butter

Once the all the cupcakes are filled, you will top off the peanut butter filling. Take a small amount of peanut butter fudge mixture. Roll it into a 1/2″ ball and place on top of the fudge in the cupcake. Gently press it to adhere to the fudge inside. You will frost over the the fudge filling. 

Icing Directions:

Now that all the cupcakes are filled, it’s time to make the chocolate frosting. Add butter, cocoa powder and sugar to a mixer bowl and beat well. Next add vanilla and milk and beat until icing is spreadable. You can also use your favorite pre-made chocolate frosting. 

piping chocolate frosting on to a cupcake

To frost the cupcakes, place a 1m tip onto a pastry bag and add icing to bag. The 1M is the standard pastry tip for piping frosting on to cupcakes. If you like to frost your cupcakes, this is the tip to get.  Pipe the frosting around the peanut butter ball and then work your way to the outer edge each cupcake. Cover the peanut butter entirely. 

The cupcakes are ready to go! You can store in the fridge for a day but these are best eaten fresh.

    Your Peanut Butter-filled cupcakes are inspired! The “divots” are good for snacking but, imho, are just made to scatter over a dish of vanilla ice cream. Perfect plus! Thank you very much.
