How To Make Oatmeal Peanut Butter Sandwich Cookies

yield about 16 sandwiches
For the cookies:

• 1/2 cup butter, softened
• 1/2 cup peanut butter
• 1/2 cup white sugar
• 1 egg
• 1 tsp vanilla extract
• 3/4 cup all-purpose flour
• 1/2 tsp salt
• 1/2 tsp baking soda
• 1/4 tsp baking powder
• 1 cup quick cooking oats

For the filling:

• 1 cup powdered sugar
• 1/2 cup peanut butter
• 3 tbsp butter, softened
• 3 tbsp whipping cream

Pre-heat the oven to 350 degrees. Begin by creaming the butter and sugars for the cookies. Beat in the egg and vanilla. In a small bowl mix together your flour, baking soda, baking powder, and salt. Mix into the creamed butter and sugars. Mix in the oats and stir until combined. Drop teaspoonfuls (or use a small cookie scoop) of dough onto a parchment lined baking sheet. Make a criss cross with a fork to flatten the cookies. Bake for 10 minutes and allow to cool.
To make the filling, beat all ingredients together until well mixed and smooth. Spread the filling on the bottom of one cookie and top with another to form a sandwich. Repeat with all the cookies.
