Preheat oven to 350℉ or 175℃. Line a baking sheet with parchment paper. Set aside.
In a mixing bowl, beat together butter, light brown sugar, and granulated sugar with a hand mixer until the mixture is almost smooth.
Add egg and vanilla extract, beat again until the mixture is fluffy. Then add in peanut butter and beat until well combined. Add flour, baking soda, baking powder, and salt, beat again until just combined. Scrape side of the bowl every time you add groups of ingredients.
Scoop the dough with a 2 tbsp cookie scoop then place it on baking sheet spacing 2 inch apart. With a fork, press slightly to create horizontal and vertical line on top of the cookies.
Sprinkle the cookies with a sugar then bake for 9-10 minutes. Let it cool for 5 minutes before removing to wire racks to cool completely. Cookies are ready to serve, enjoy!
