Ingredients

1 1/4 cup all-purpose flour
3/4 teaspoon baking powder
1/2 teaspoon baking soda
1/2 teaspoon salt
1 large egg
1/2 cup sugar
1/2 cup unsalted butter
1/2 cup creamy peanut butter
1/2 cup brown sugar

Directions

Sift together flour, salt, baking powder and baking soda. Cream butter with sugar, brown sugar and peanut butter, creaming after each addition until light and fluffy. Add egg and mix thoroughly. Add flour mixture gradually. Beat until smooth. Drop mixture, 1 teaspoon at a time and about 2″ apart on to an undressed baking sheet. Flatten with a fork 2 times to form a crisscross pattern on the cookie surface. Bake in a 350 F oven for 8-10 min. Remove from oven and cool.
