Preheat oven to 350 degrees. Spray a cookie sheet with nonstick spray. Set aside.
Using a stand mixer or hand mixer, cream peanut butter, butter, and white and brown sugars. Cream until smooth. Add egg and vanilla. Mix well.
In another bowl, mix flour, baking soda, baking powder, and salt.
Using a slow speed on your mixer, slowly combine the flour mixture with the peanut butter mixture. Mix until combined.
Using a small cookie scoop or a tablespoon, roll the dough into balls and place them on the baking sheet.
Use the back of a fork and press down each ball to flatten. Use criss-cross patterns.
Bake 8-9 minutes. Let cool slightly on the baking sheet and then transfer to a cooling rack.
