Get a medium bowl out, measure the flour into it then add the baking soda and salt and whisk together, set aside.
In a large mixing bowl using a hand mixer or a stand mixer, cream together the butter and sugars until light and fluffy, 3-4 minutes. Add in the egg and mix until combined then add in the peanut butter and vanilla extract.
Next, add in the flour mixture and mix on low to combine. Chill in refrigerator either in mixing bowl or transfer to another bowl, cover with plastic wrap and chill for at least thirty (30) minutes.
When ready to bake, heat oven to 350 Deg F ( 176C) and set out baking sheets with parchment paper.
Fill a small bowl with the granulated sugar and another with the turbinado (raw) sugar.
Roll out the dough in 14 gram sized balls ( a generous tablespoon), roll in the granulated sugar first then the raw sugar. Place a few inches apart on a baking sheet then chill until firm. I chill in the freezer to make this step faster.
Bake the cookies for 9-10 minutes until puffed and golden, remove from the oven and quickly indent the middles with the end of a wooden spoon or a round measuring spoon. Let cool for a few minutes on the baking sheet then transfer to a wire rack to cool completely before filling. Repeat until you have 44 cookies baked.
