Banana Cookies

Preheat oven to 350°.

In a medium bowl, combine oats, flour, baking powder, baking soda and salt.

In a large bowl with mixer at medium speed, beat peanut butter and margarine until smooth. Beat in sugars until blended.

Beat in banana, egg and vanilla. Stir in flour mixture.

Drop dough by one-fourth cupfuls, about 5 inches apart, onto ungreased cookie sheets.

With spatula, spread dough into 3 1/2-inch circles.

Bake in a 350° oven for 10 to 12 minutes or until golden.

Let cool on cookie sheets for 4 minutes. Remove from cookie sheets; cool completely on a wire rack.

If desired, pipe a stars or stripes frosting design, using plain piping, onto each cookie.

Store in a tightly-covered container. Makes about 24 cookies.
