Preheat your oven to 350°F (175°C). Line two baking sheets with parchment paper to prevent sticking and make cleanup easier.

In a large mixing bowl, combine the peanut butter, sugar, and egg. Mix using a wooden spoon or electric mixer until everything is smooth and well combined. The dough will be quite thick.

Use a medium cookie scoop to portion out the dough, then roll each portion between your palms to form balls. Place them on the prepared baking sheets, leaving about 2 inches between each cookie. Using the back of a fork, press down on each ball to create a crisscross pattern and flatten the cookies.

Bake in the preheated oven for 8-10 minutes or until the edges are slightly browned. Don't overbake - they'll still be soft in the center but will firm up as they cool.

Remove from the oven and let the cookies rest on the baking sheet for 2 minutes, then transfer to a wire cooling rack to cool completely for about 5 minutes before enjoying.
