Cream butter and sugars together until smooth. Beat in peanut butter, egg, milk, and vanilla, and mix until smooth and creamy. Add dry ingredients and mix just until dough forms.
Scoop dough into 1 tablespoon-sized balls and place on a baking sheet lined with parchment paper. Bake cookies at 375 degrees for 7-8 minutes.
Immediately press a thin peanut butter cup onto the top of each cookie as soon as they come out of the oven. Allow cookies to stand for a few minutes to allow the tops to get glossy and soft before decorating.
