Ingredients:
Cookies
1 cup flour
1 teaspoon baking powder
2 teaspoons baking soda
2 sticks butter, softened
1/2 cup creamy peanut butter
1/2 cup sugar
1/2 cup light brown sugar
1 egg
1 teaspoon vanilla
1 1/4 cup quick-cooking oats
Filling
1 stick butter, room temperature
1/2 cup creamy peanut butter
1 1/2 cups powdered sugar
Preheat oven to 350F. Sift together flour, baking powder and baking soda. Set aside. In a separate bowl, beat together butter and peanut butter. Add sugars and cream together for several minutes. Add egg and vanilla and mix until just combined. Fold in the oats. Use either parchment paper or cooking spray on baking pans. Scoop our small balls of dough and place on pan. Bake about 10 to 12 minutes. When slightly golden, remove and cool on a wire rack.
To prepare the filling, cream together the butter, peanut butter and powdered sugar–it should be the consistency of thick paste, not runny. If it needs to be thinned, add a small about of water. If the filling needs to be thickened, add a small amount of powdered sugar. Fill the cookies after completely cooled and serve.
