Ingredients Method

Ingredients
  

Peanut Butter Buttercream
  • 6 tablespoons butter, softened
  • 3 tablespoons peanut butter
  • 1 1/2 cups confectioner's sugar
  • 4 tablespoons heavy cream
  • 24 chocolate cupcakes
  • chocolate frosting

Method
 

  1. Bake cupcakes and let cool completely.
  2. If making chocolate frosting, make it now and set aside.
Make Peanut Butter Buttercream:
  1. Add peanut butter to softened butter in a large mixing bowl.
  2. Mix peanut butter and butter together until creamy and well combined.
  3. Gradually add confectioner's sugar and beat until sugar is completely incorporated.
  4. Add heavy cream, one tablespoon at a time, until frosting is desired consistency.
  5. This will make a little more frosting than you need for 24 cupcakes. You can keep the rest in the fridge for 3 days and use it to ice additional cupcakes. It will harden in the fridge - let it sit out at room temperature for about a half-hour and if necessary, mix in more heavy cream, one tablespoon at a time.
Fill, Frost and Decorate:
  1. Fill decorating bag about 1/2 full of peanut butter buttercream. Using a large round decorating tip (Wilton #10), push down into the cupcake to fill with peanut butter buttercream. As you squeeze the decorating bag, you should see the cupcake fill. Be careful not to squeeze too hard, or the cupcake can crack. If this happens, simply squeeze the two sides together around the filling. Repeat for each cupcake, refilling decorating bag as necessary.
  2. Fill a second decorating bag about 1/2 full of chocolate frosting. Using a large star tip (Wilton #1M), pipe a large star on top of each cupcake, covering the hole where the filling went in. Alternatively, you can just frost the entire top of each cupcake with chocolate frosting.
  3. Change the tip on the peanut butter buttercream decorating bag to a small star tip (I used Wilton #16, but any star tip smaller than the first one will work. Pipe a small star on top of each cupcake.
