Preparation Steps

• Preheat oven to 350°F (175°C). Line baking sheets with parchment paper.

• In a large bowl, cream together butter, granulated sugar, and brown sugar until light and fluffy. Beat in egg and vanilla extract.
• Gradually add the dry ingredients to the wet ingredients, alternating with milk, beginning and ending with dry ingredients. Mix until just combined.
• Drop by rounded tablespoons onto prepared baking sheets. Bake for 10-12 minutes, or until edges are set.
• Let cool on baking sheets for a few minutes before transferring to a wire rack to cool completely.
• To make the filling: In a large bowl, beat together butter, powdered sugar, peanut butter, and milk until smooth and creamy.
