1-Preheat the oven: Begin by preheating your oven to 350°F (175°C) and lining a baking sheet with parchment paper for easy cleanup.

2-Mix the wet ingredients and sugars: In a mixing bowl, combine the peanut butter, unsalted butter, brown sugar, and granulated sugar, beating them until light and fluffy this creates the base for that wonderful texture.

3-Add eggs and vanilla: Next, add the egg, egg yolk, and vanilla extract, mixing until everything blends smoothly; don’t forget to scrape down the sides for even incorporation.

4-Incorporate dry ingredients and chips: Gradually whisk in the dry ingredients flour, cornstarch, baking soda, baking powder, and salt to form the dough, then fold in the peanut butter chips for those tasty bursts.

5-Chill the dough: Chill the dough for at least an hour to enhance flavor and prevent spreading, a tip that works wonders just like letting meat rest after grilling.

6-Shape and prepare the cookies for baking: Once chilled, scoop the dough with a 2-tablespoon measure, roll in extra granulated sugar, and place on the baking sheet. Flatten each ball gently and add a crisscross pattern with a fork for that classic look.

7-Bake and cool: Bake for 9-11 minutes until the edges turn golden but the centers stay soft, then let them cool on the sheet before moving to a rack.
