Step 1

Preheat the oven to 350° and have ready a baking sheet lined with parchment paper or a silicone baking mat. Also, have ready a small bowl with about a 1/4 cup of sugar for coating the cookie dough balls.

Step 2

In a medium-sized mixing bowl, whisk together flour, baking powder, and salt.

Step 3

In a large mixing bowl, combine butter, light brown sugar, granulated sugar, peanut butter, egg, and vanilla. With a handheld mixer on medium-high speed, mix until smooth.

Step 4

Add the dry ingredients and mix on low speed until combined. Do not overmix.

Step 5

Scoop out heaping tablespoons of dough, and roll into a ball. Roll in the granulated sugar, and transfer to the baking sheet spacing them 1 1/2"-2" apart.

Step 6

Make crosshatch lines across the tops of the cookies using the tines of a fork, and bake for 12-14 minutes, just until the edges are a deeper brown. Serve and enjoy.
