Halloween Funfetti with Vanilla Frosting

Preheat oven to 350 degrees (F).

Mix flour, baking powder, and salt together in a bowl. Add butter and sugar to another bowl and beat until creamy. Add eggs and egg whites one at a time, beating on low. Add extracts, beat another minute. To the creamed mixture, alternate adding the dry ingredients and the 1 cup milk, starting and ending with the dry ingredients. Stir in the sprinkles. Pour the batter into a greased and floured sheet pan.

Bake for 17-20 minutes or until toothpick inserted into the middle comes out clean. Cool on wire racks.

Beat one stick of butter until creamy. Add 4 cups powdered sugar, 1/8 cup of milk, and 1 teaspoon vanilla extract. Beat a few more minutes. For stiffer frosting, add more powdered sugar. For thinner frosting, add more milk. Once the cake is cool frost it and top with more sprinkles.
