Description

These Chocolate Peanut Butter Whoopie Pies are soft and moist chocolate cakes with a creamy peanut butter frosting sandwiched in between. It’s a classic, yet simple treat that is easy to make for any occasion!


Scale

Ingredients

whoopie pie cakes

peanut butter frosting

  • 1 cup (2 sticks) Unsalted Butter, room temperature
  • 1 cup Peanut Butter, creamy
  • 22 1/2 cups Confectioners Sugar, sifted
  • 23 tablespoons Heavy Whipping Cream
  • 2 teaspoons Vanilla Extract

Instructions

whoopie pie cakes

  1. Adjust oven rack to 2nd level position and preheat the oven to 375ºF. Line baking sheets with parchment paper and set aside.
  2. In a large bowl, whisk together the all-purpose flour, unsweetened cocoa powder, baking soda, and salt. Set aside.
  3. Using your hand-held mixer or a stand mixer fitted with the paddle attachment, beat the vegetable shortening and granulated sugar together on medium-high speed until nice and fluffy. Add in the egg and vanilla extract, then mix until completely blended. Scrape down the sides of the bowl as needed.
  4. Switch the mixer speed to low, then alternatively add a little of the whisked dry mixture, followed by a little of the milk and water. Repeat until all ingredients have been added and the mixture is completely blended. 
  5. Using a cookie scoop (I used my 1 1/2 tablespoon or medium size cookie scoop), drop a generous scoop of batter on to the lined baking sheet, spacing each cake about 1 1/2- to 2-inches apart. I got 6-8 cakes on each baking sheet. They will spread out, but not by a lot.
  6. Place in the oven and bake at 375ºF for 12-14 minutes or until the center of the cakes spring back when lightly pressed.
  7. Allow cakes to cool slightly on the baking sheet for about 5 minutes before transferring them to a cooling rack.

peanut butter frosting

  1. Using your hand-held mixer or a stand mixer fitted with the paddle attachment, beat the unsalted butter and peanut butter together until smooth. Add in the vanilla extract.
  2. Switch the mixer speed to low and gradually add in the sifted confectioners sugar, then add in the heavy whipping cream. Scrape down the sides of the bowl as needed.
  3. Using a small spatula or piping bag with a tip of your choice, add the peanut butter frosting to the bottom of a whoopie pie cake. Then top with another cake. 

Notes

  • To scoop out the batter I used my 1 1/2 tablespoon or medium size cookie scoop which gave me roughly a 3-inch diameter chocolate cakes. And I was definitely generous when I went to scoop out the batter to drop it onto the parchment lined baking sheet.
  • You could even get away with using the 2-inch cookie scoop if you wanted to make them a little bigger.
  • You can keep each whoopie pie tightly wrapped in plastic wrap out at room temperature for up to 2 days. Alternatively, you can can store them wrapped and kept in an airtight container in the fridge for up to about 5 days; or—my favorite—you can wrap them tightly in plastic wrap, place in a sealed freezer bag, and keep in the freezer where they can last about 3 months.
  • If you’re not going to fill the whoopie pie cakes that same day, you can keep the peanut butter frosting covered tightly in the mixing bowl with plastic wrap in the fridge overnight. When you’re ready, take out of the fridge and allow to come to room temp before filling the whoopie pie cakes. You may need to re-whip the frosting a little to bring it back to life.
  • You can easily double both the whoopie pie cake and peanut butter frosting recipes for more whoopie pies.
