3/4 cup flour
1/2 tsp baking soda
1/4 tsp baking powder
1/2 tsp salt
1/2 cup butter, at room temperature
1/2 cup homemade peanut butter
1/2 cup white sugar
1/2 cup brown sugar
1 tsp homemade pure vanilla extract
1 cup quick cooking oats
3 TBS butter, softened
1 cup powdered sugar
1/2 cup smooth peanut butter
2-1/2 TBS heavy cream
Preheat oven to 350 degrees. Grease cookie sheets with butter or cooking spray.
Cream together 1/2 cup butter or margarine, 1/2 cup peanut butter, white sugar, brown sugar, and vanilla in a large bowl. Add egg and beat well.
In another bowl, combine the flour, baking soda, baking powder, and salt. Add the dry ingredients into the creamed mixture in thirds, beating well after each addition. Add oatmeal and mix well.
Drop dough by teaspoons onto greased baking sheet, and press each mound down with a fork to form 1/4-inch thick cookies. Bake for 10 minutes, or until cookies are a light brown. Cool cookies in a rack.
To make the filling, cream 3 tablespoons butter or margarine with the powdered sugar. Add peanut butter and heavy cream and beat until smooth. Spread filling onto half of the cooled cookies, then top with the other half to form sandwiches.
