Banana Peanut-Butter Sandwich Cookies

1/2 cup softened butter or margarine
1/2 cup solid vegetable shortening
1 cup plus 1/4 cup granulated sugar, divided
1/2 cup packed brown sugar
2 large ripe bananas, pureed or mashed (1 cup)
2 large eggs 2 teaspoons vanilla extract
3 cups all-purpose flour 1 teaspoon baking soda
1/4 teaspoon salt
1 teaspoon ground cinnamon
1 cup peanut butter

Preheat oven to 350F.

Beat together butter, shortening, 1 cup granulated sugar and brown sugar until creamy. Beat in bananas, eggs and vanilla.

Stir together flour, soda and salt until blended. Stir mixture into banana mixture until well blended. Drop mixture by heaping rounded teaspoonfuls onto ungreased cookie sheets.

Stir together remaining 1/4 cup granulated sugar and cinnamon; sprinkle mixture over cookies. Flatten each cookie with the bottom of a glass.

Bake 9 to 10 minutes, or until cookies are set, and light brown around the edges (cookie tops will not brown). Transfer cookies to a wire rack; cool.

Spread bottoms of half the cookies with peanut butter; top with a second cookie (bottoms together). Store cookies in a tightly covered container.
