Vanilla Whoopie Pies with Chocolate Buttercream

Whoopie pies are one of my favorite bite size treats. These feature a soft vanilla cookie with a delectable chocolate buttercream in the center. If you want to make these truly indulgent you can add a little peanut butter on one of the cookies before you sandwich them together or roll them in sprinkles to add color and texture.

Ingredients:

Cookies-

2 1/2 cups all-purpose flour

1/2 cup vanilla protein powder

1 teaspoon baking soda

3/4 teaspoon baking powder

3/4 teaspoon salt

1 cup granulated sugar

1 stick unsalted butter at room temperature

2 teaspoons vanilla extract

1 large egg

2/3 cup buttermilk

Buttercream Filling-

1 1/2 pounds confectioners’ sugar

1 1/2 sticks unsalted butter at room temperature

1/4 cup cocoa powder

3. Beat the granulated sugar, butter, and vanilla in a large bowl on medium speed until light and fluffy.
4. Add the egg and beat until combined.
5. Reduce the speed to low and alternate adding dry ingredients and buttermilk in small batches.
6. Scrape the sides of the bowl and cover to refrigerate for at least 30 minutes.
