In another bowl, combine the flour, baking soda, baking powder, and oatmeal. Add to creamed mixture.
Drop by teaspoons onto greased baking sheet. Bake at 350 degrees F for 10 minutes, or until cookies are a light brown. After removing cookies from the oven, press flat with a spatula, place cookie on wire rack to cool.
To Make Filling: Cream 3 tablespoons butter or margarine with the confectioners’ sugar, 1/2 cup smooth peanut butter, and the cream. Add cream a tablespoon at a time until the mixture is smooth but not runny. You may not need all of the cream. Spread filling onto half of the cooled cookies, then top with the other half to form sandwiches.
