1) Preheat oven to 375 degrees. Prepare baking sheet by using parchment, spraying with cooking spray or using a Slip-Mat.
2) Cream together the butter, peanut butters and sugars. Add the eggs one at a time until mixed together well.
3) In a separate bowl, mix the dry ingredients.
4) With the mixer on low speed, add the dry ingredients to the wet. Once combined add the vanilla.
6) Let chill in the fridge for at least 30 minutes but maybe even longer.
7) When you are ready to bake, make small balls of dough and roll into a bowl of sugar. Place each one on baking sheet and gently press flat with the tines of a fork.
8) Bake for 5-8 minutes. They bake quick so watch them.
