In your mixer, mix together butter, sugar, and baking powder until well combined. Add egg, milk, and vanilla, mixing thoroughly. Add flour 1/2 cup at a time.
Roll dough out on a floured surface, cut with your favorite cookie cutters, and place on a lightly greased cookie sheet.
Bake at 375 for 7 minutes. If you like a harder cookie, bake for a minute or so longer. I love my cookies nice and soft so I usually watch them pretty carefully to make sure I don’t overcook them
Frost with your favorite buttercream frosting, and enjoy!
Recipe Notes
NOTE: I usually throw my dough in the freezer for a few minutes to help it set up before I roll it out. I know that most people refrigerate it, but I am far too impatient for that!
