Instructions

Whoopie Pies

Preheat oven to 350 degrees F. Using a whoopie pie pan, coat with butter or shortening and dust generously with flour. Tap out excess flour.
In a large mixing bowl, add in the 15.25 ounce box yellow cake mix, 3 large eggs, ½ cup water, and ½ cup vegetable oil. Beat with a hand mixer on medium until incorporated.
Once combined, fold in ½ cup sprinkles.
Using a ¼ measuring cup, drop batter into each floured cavity.
Bake for 12-15 minutes. Allow to cool for 5 minutes and turn out onto a wire rack to cool completely.

Frosting

In a medium bowl, add 1/2 cup butter, 2 cups powdered sugar, 1 teaspoon vanilla extract and 1 tablespoon of milk. Beat with hand mixer on low. If the frosting is too thick, add an extra tablespoon of milk. Once powdered sugar is incorporated, beat on medium/high for 30 seconds to a minute.
Fold in 1/3 cup sprinkles.
On the flat side of one whoopie pie, spread center filling and sandwich with another whoopie pie.
Store in an air tight container.

Notes

Storage: Store the whoopie pies in an airtight container for up to 5 days at room temperature. To transport them, wrap them tightly in plastic wrap.

Freezing: To freeze these whoopie pies, bake, cool, and frost them. Wrap each individual whoopie pie tightly in two layers of plastic wrap. Place them in a freezer-safe container or freezer bag and freeze for up to 3 months.

Thaw: Place on the counter and let thaw for 1 to 2 hours before serving.
