These are one of my boyfriend's favorite cookies. Most of the time I don't bother to make them into sandwich-style cookies. Really yummy either way.
- 3/4 cup all-purpose flour
- 1/2 teaspoon baking soda
- 1/4 teaspoon baking powder
- 1/2 teaspoon salt
- 1/2 cup butter, softened
- 1/2 cup peanut butter
- 1/2 cup white sugar
- 1/2 cup packed light brown sugar
- 1 egg
- 1 teaspoon vanilla extract
- 1 cup quick cooking oats
- 3 tablespoons butter, softened
- 1 cup confectioners' sugar
- 1/2 cup smooth peanut butter
- 2 1/2 tablespoons heavy whipping cream
- In a large bowl, cream together 1/2 cup butter or margarine, 1/2 cup peanut butter, white sugar, brown sugar, and vanilla. Add egg and beat well.
- In another bowl, combine the flour, baking soda, baking powder, and salt. Add these dry ingredients to the creamed mixture. Stir. Add oatmeal and stir.
- Drop by teaspoons onto greased baking sheet, and press each mound down with a fork to form 1/4 inch thick cookies. Bake at 350 degrees F (175 degrees C) for 10 minutes, or until cookies are a light brown.They are PB cookies, so make sure to not overbake.
- To Make Filling: Cream 3 tablespoons butter or margarine with the confectioners' sugar, 1/2 cup smooth peanut butter, and the cream. Spread filling onto half of the cooled cookies, then top with the other half to form sandwiches.
