PB Sandwich Cookies

• 1/2 cup butter, softened
• 1/2 cup white sugar
• 1/2 cup packed light brown sugar
• 1/2 cup peanut butter (I used extra chunky)
• 1 egg
• 1 teaspoon vanilla extract
• 3/4 cup all-purpose flour
• 1/2 teaspoon baking soda
• 1/4 teaspoon baking powder
• 1/2 teaspoon salt
• 1 cup quick cooking oats

Filling:

• 3 tablespoons butter, softened
• 1 cup confectioners’ sugar
• 1/2 cup creamy peanut butter
• 2 1/2 tablespoons heavy whipping cream

1. In  a small bowl, combine the flour, bs, bp & salt. Cream the butter and sugars together until fluffy. Add in the peanut butter until well-mixed. Beat in the egg and vanilla. Mix in the flour mixture. Stir in the oats. Refrigerate for two hours.
2. Preheat the oven to 325 degrees. Using a cookie scoop, make 24 uniform dough balls. Cut them in half and roll into balls (48 total). Place onto a lightly greased cookie sheet, and flatten slightly with a fork. They will be small cookies! That's okay! Bake for 8-10 minutes, until the cookies are a light golden brown. Allow the cookies to cool completely.
3. Cream 3 tablespoons butter with the confectioners’ sugar, 1/2 cup smooth peanut butter, and the cream until light and fluffy.
4. Fill the filling into a large ziplock bag, cut one of the corners, and squeeze the filling onto half of the cooled cookies, then top with the other half, squeeze them together until the filling reaches the ends of the cookie!
