Easy Recipe for Whoopie Pies

Start by combining the cake mix, egg, and butter in a medium bowl. Beat it together until it’s mixed well. I like using a hand mixer best, it’s easy to clean and gives a creamy batter versus just using a fork or spoon.

Gently stir in the sprinkles using a spoon adding as many as you would like.

Roll it into about 1-inch balls and place them on a cookie sheet. Lightly press the cookies down about halfway with the bottom of a cup, and bake them for 8-10 minutes on 350 degrees.

Divide the frosting and mix in 3 or 4 colors of your choice. Place each color of frosting into a plastic baggie, and snip the corner off to use for piping.

When your cake cookies are cooled down completely you are ready to add the icing.

Pipe a round mound of frosting on the bottom of one cookie and gently press another cookie on top of it. Repeat this until all the cookies are frosted and topped with another cookie.

Serve these pretty funfetti whoopie pies for a party, bridal shower, or a delicious snack.
