Funfetti Whoopie Pies

Funfetti Whoopie Pies

Cookies:

2 sticks softened butter
1 1/4 cup sugar
2 teaspoons vanilla
1 teaspoon imitation butter flavor
1 egg
2 cups cake flour
2/3 all-purpose flour
3/4 teaspoon baking soda
1/2 teaspoon salt
1/2 cup colored sprinkles (I used the long kind)
More sprinkles for rolling (I used the little round kind)

Beat the butter and sugar on high speed for about 5 minutes or until fluffy. Add the vanilla, butter flavor, and egg. Beat until well combined. Sift in the flours, soda, and salt. Mix to combine. Stir in the sprinkles. Chill the dough. If you're in a hurry, throw in in the freezer. I put it in a gallon ziploc bag and pounded it down flat so it would get cold faster. Preheat the oven to 375º. Take a small piece of the dough, dip in the sprinkles and roll into a ball and place on the baking sheet. Repeat until the sheet is filled. Bake about 7 minutes. Keep the remaining dough in the freezer while the other are baking. They will flatten out as the bake and puff up a little when they're done. Sandwich cooled cookies together with filling if desired (recipe below).

Filling:

1/2 cup heavy cream
1 teaspoon vanilla
2 cups powdered sugar
2 sticks cold butter, chopped into small cubes
2 tablespoons sprinkles (I used the little round ones)

Beat the cream and vanilla until slightly thickened. Beat in the powdered sugar until thick and smooth. Beat in about one fourth of the cold butter cubes at a time on high speed. Beat for about 10 minutes on high speed in your stand mixer until smooth. Don't be afraid if it looks weird at first. Just keep beating! Fold in the sprinkles. Use to fill cooled cookies.
