Beat butter, peanut butter, and sugars until creamy. Add eggs one at a time, then vanilla. Mix baking powder with flour, then add flour a cup at a time.
Roll dough out on a lightly floured surface and cut with a cookie cutter dipped in flour so it doesn't stick.
I made some cookies thicker than others and I really liked the chewiness of the thicker cookies, so next time I will be making them all thick!
Bake at 350 for 10-13 minutes. Until they are just getting golden on the bottom, to ensure you will not have a dry cookie.
The cookies with the fork marks are crispier, so if you prefer a crispy cookie. Press a for on the tops of the cookies creating a criss-cross design.
