1/2 cup sugar
1/2 cup brown sugar, packed
1/2 cup crunchy peanut butter
1/4 cup shortening
1/4 cup butter, softened
1 egg
1 1/4 cups all-purpose flour
1 teaspoon baking powder
1/4 teaspoon baking soda
1/4 teaspoon salt
Granulated sugar

Directions:

Combine the sugar, brown sugar, peanut butter, shortening and butter in a mixing bowl.  Mix until well combined.  Stir in flour baking powder, baking soda and salt.  Wrap the dough in plastic wrap and refrigerated until well-chilled, about 2 hours.

Preheat oven to 375ºF.

Roll the dough into balls about 1 1/4 inch wide.  Place about 3 inches apart on a baking sheet.  Flatten the balls using a potato masher or a fork that has been dipped in the extra granulated sugar.

Bake for 10-12 minutes, or until lightly browned.  Allow to cool for 1 minute on the baking sheet before removing to a cooling rack to cool completely.

Makes about 2 1/2 dozen cookies.
