Step 1 - In a stand mixer, cream the butter and sugars together on medium speed until it's smooth.
Step 2 - Add the egg and mix on until well combined
Step 3 - Add the vanilla and peanut butter and mix on high until combined
Step 4 - In a separate bowl, mix the flour, baking soda, baking powder and salt together
Step 5 - Add the flour mixture to the wet ingredients and mix on low until combined
Step 6 - Refrigerate for 4 hours
Step 7- Preheat the oven to 350 degrees and line to baking sheet with a silicone baking mat
Step 8 - Roll the balls (I use a small cookie scoop to make the 1 inch cookies) of dough into granulated sugar and place on the baking sheet
Step 9 - Press a fork into the tops to create the criss-cross pattern. Bake for 10 minutes or until they are slightly browned on the edges. Remove from oven and let them cool on the sheet for 5 minutes. Enjoy!
