Divide Dough: Using a cookie scoop or tablespoon measuring spoon, measure roughly 2 tablespoons of cookie dough (roughly 1.2 ounces). Roll into a ball. You should have 24 cookie dough balls.
Cookie Sheet: Line your two cookie sheets with parchment paper. Place 9-12 balls of dough onto each cookie sheet. Flatten cookie dough with a fork in a criss-cross pattern.
Bake for 13 minutes or until the edges are golden brown. The middle of the cookies should still be soft. Let cool on a wire rack for 10 minutes. Enjoy!
Peanut Butter: It is best to skip the natural peanut butter and go for brands such as Jif or Skippy.
Baking: Bake the cookies until they're almost done. They will be very soft but don't worry. They will continue to bake after they are taken out of the hot oven.
