Step 1

Preheat oven to 350 degrees F. Line two 18 by 13-inch baking sheets with silicone baking liners or parchment paper.

Step 2

In a medium mixing bowl whisk together flour, baking soda, baking powder, and salt. Set aside.

Step 3

In the bowl of an electric stand mixer fitted with the paddle attachment cream together butter, granulated sugar, and brown sugar until combined.

Step 4

Mix in peanut butter then blend in egg and vanilla. With mixer set on low speed slowly add in flour mixture and mix just until combined.

Step 5

Scoop dough out and shape into balls (30 grams each or nearly 2 Tbsp) then place on baking sheets spacing them 2-inches apart.

Step 6

Using a long pronged fork flatten cookies slightly then turn fork going opposite direction and flatten just slightly again (it should create that criss cross pattern).

Step 7

Bake cookies in preheated oven, one sheet at a time, for about 9 minutes (cookies will appear pale and slightly under-baked, they'll continue to cook slightly as they cool).

Step 8

Let cool on baking sheet 5 minutes then transfer to a wire rack to cool completely. Store cookies and an airtight container.
