Banana and Strawberry Whoopie Pies

I obviously have a thing for bananas, and this time, strawberries too!

Banana Cakes         about 12 whole whoopie pies



    2 cups all-purpose flour
    1/2 teaspoon baking powder
    1/2 teaspoon baking soda
    1/2 teaspoon salt
    2 medium mashed bananas
    1/2 cup buttermilk
    4 ounces (1 stick) unsalted butter, softened
    1/2 cup granulated sugar
    1/2 cup packed light-brown sugar
    1 large egg
    1 teaspoon vanilla extract


Whip butter and sugars until fluffy, about 3 minutes.  Add 1 egg and vanilla, mix until combined.  Combine all dry ingredients in a bowl, set aside.  Combine bananas and buttermilk in bowl, set aside.  Add banana mixture into butter mixture, alternating with dry mixture.  Do this in 2-3 turns until well combined.  Pipe out batter onto tray about 1 1/4 inch dollops, keep cakes at least 1 1/2 apart (more if possible).  Bake for 12-14 minutes until golden.

Strawberry Buttercream Filling

    2 sticks butter, room temp
    1/3 cup strawberry puree (or preserves)
    1 teaspoon vanilla extract
    2 1/2 cups powdered sugar


Whip butter until fluffy, about 3-5 minutes. Add vanilla and puree, whip until combined.  Add powdered sugar slowly until combined.  Add more or less, depending on consistency.  Pipe onto cakes and sandwich.  Dust with powdered sugar or chocolate drizzle. Refrigerate until ready to serve.
