Tempting Peanut Butter Whoopie Pies with Buttercream Filling
Did you know there was such a thing as National Peanut Month?? I definitely didn’t until I teamed up with a great group of bloggers to bring you a Unit Study on Peanuts. I am sharing a recipe for Peanut Butter Whoopie Pies with an amazing addition – mini Reese’s Pieces!
- 1-3/4 cups flour
- 1 tsp baking soda
- 1 tsp baking powder
- 1/2 tsp salt
- 4 tbs unsalted butter
- 4 tbs vegetable shortening
- 1/2 cup brown sugar
- 1/2 cup peanut butter
- 1 tsp vanilla
- 2 large eggs
- 1-1/2 cups buttermilk
- 1/2 cup mini Reese's Pieces (***my addition)
- Preheat the oven to 375.
- In a stand mixer - beat butter, shortening, brown sugar, peanut butter and vanilla until light and creamy (roughly 3 minutes).
- Add eggs one at a time and beat thoroughly after each addition.
- Scrape sides of bowl.
- Add baking soda, baking powder, salt and half of the flour - beat on medium speed until just combined.
- Add half of the buttermilk - beat on medium speed until just combined.
- Repeat with remaining flour and buttermilk. Beat until fully combined.
- Add Reeses Pieces and mix.
- Use a cookie scoop and scoop batter onto cookie sheets.
- Bake roughly 10 minutes - until cakes are firm to touch.
- Remove from oven and cool on the cookie sheet for 5 minutes and on a cooling rack until completely cooled.
- Fill with Wilton Buttercream.
- Put mini Reese's Pieces in a bowl and roll the outer edge of the whoopie pie until the filling is covered.
The recipe for Wilton Buttercream can be found here.
The kids and I made these amazing Peanut Butter Whoopie Pies together. They love helping me bake 🙂 They take turns helping to add the ingredients and of course love to help clean the bowl when we are done.
The most exciting part of this recipe to me is the addition of the mini Reese’s Pieces. We added them to the cake batter and garnished the finished whoopie pie with them.
We had a great time making our Peanut Butter Whoopie Pies and will also be trying out a few more great peanut themed activities this month in honor National Peanut Month. Take a look below at some other great peanut resources.
