Red, White, and Blue Whoopie Pies

"Ever since I was first allowed to purchase Whoopie Pies at the grocery store bakery, I have been hooked! They are like mini delicious cakes with a pillowy soft marshmallow frosting. They are totally poppable. One will never be enough! I jazzed these up for the fourth of July. I highly recommend using gel dyes to get the brightest color. This is especially true for red as typical food coloring usually gives a dark pink at best."
