2 1/2 cups butter, softened
1 cup brown sugar
1 cup crushed banana
1 cup white sugar
1 teaspoon vanilla extract
3 egg whites
2 teaspoons banana extract
Preheat oven to 375 degrees F (190 degrees C). Grease cookie sheets.
In a large bowl, cream together the butter, brown sugar, banana, and white sugar until smooth. Pour the batter into the prepared cookie sheets.
Bake for 9 to 11 minutes in the preheated oven, or until a wooden toothpick inserted into the center of the cookie turned into a small brown spot. Cool completely on the baking sheet. While cookies are still warm, sprinkle with banana extract.
