Preheat oven to 350 degrees.

In a stand mixer, combine butter, peanut butter, and both sugars. Cream together for 4 minutes, scraping down at least twice.

Add the egg and vanilla, beat until well combined for 45-60 seconds.

Add salt, flour, and baking soda; mix at low speed until flour is completely worked in. Quickly mix at full speed for 2 seconds.

Use a 1-ounce scoop to place cookies onto a parchment-lined cookie sheet.

With a fork, moisten some of the dough, dip in sugar and create a crosshatch pattern on cookies, tamping fork in sugar after each press.

Bake in the preheated oven for 12-14 minutes, until the top and edges begin to turn golden brown.

Remove from oven and transfer to a cooling rack.
