Peanut Butter Banana Sandwich Cookies

Ingredients
1 cup brown sugar (packed)
1⁄2 cup sugar
1 1⁄2 cups butter (softened, 1/2 cup for filling)
1 cup bananas (mashed, about 2 large bananas)
1 egg
1 teaspoon vanilla extract
2 3⁄4 cups flour
1⁄2 teaspoon baking soda
1⁄4 teaspoon salt
1 cup peanut butter (all natural, creamy)
1 cup powdered sugar
Instructions

Heat oven to 350° F. Beat brown sugar, sugar, and butter in large mixer bowl until creamy; add banana, egg, and vanilla. Beat until well mixed. Combine flour, baking soda, and salt in medium bowl; mix well. Add flour mixture to banana mixture; mix until soft dough forms.

Drop dough by rounded teaspoonfuls onto greased cookie sheets. Bake 11 to 13 minutes or until lightly browned. Cool on wire racks.

Beat peanut butter, butter and powdered sugar until well mixed. Spread about one tablespoon filling on bottoms of half of cookies. Gently press bottoms of remaining cookies against filling to form sandwiches.

Tip: Cookies can be frosted. Add one to two tablespoons milk to peanut butter filling, stirring until smooth. Frost tops of cookies.
