So this was a new recipe, and being a lover of both peanut butter and oatmeal, this was a must try. It's as good as anticipated! In reality, you could make these cookies without the filling/sandwiching and they are still terrific. Very easy to make, quick simple recipe!
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 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 mixing bowl, cream together butter and sugars. Add peanut butter, vanilla, and egg until all is well incorporated.
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 a parchment lined baking sheet, and press each mound down with a fork to form 1/4 inch thick cookies. Bake at 350 degrees F for 10 minutes, or until cookies are a light brown.
To Make Filling: Cream 3 tablespoons butter with the peanut butter and whipping cream. Add confectioners' sugar and stir together until a thick filling forms.
When cookies are complete cooled, spread 1/8 inch layer of filling on flat bottom of one cookie, top with a second flat bottom, forming a sandwich.
