Preheat over to 325°F.

Line a baking sheet with parchment paper and set aside.

Combine peanut butter, sugar, and egg in a medium mixing bowl.

Mix well.

Take heaping tablespoon-sized scoops of dough and roll them into balls.

Place the dough balls onto the prepared baking sheet.

Slightly press each ball down with a fork and create a criss-cross pattern.

Bake for 12 minutes.

Remove from oven.

Let cool on the baking sheet for 5 minutes and then transfer to a wire rack to fully cool.

Serve and enjoy!
