Preheat oven to 350F. In a large bowl combine all three ingredients. Once fully mixed together, continue mixing for about 1 minute or until the dough comes together and can be formed into a ball.
Roll the dough into 24 balls. Place the dough balls on ungreased baking sheets, at least 1 inch apart.
Use a fork to press onto the top of each dough ball to slightly flatten and leave the imprint of the fork. Turn the fork 90 degrees and make a second imprint to create the classic peanut butter cookie look.
Bake the cookies at 350F for 8-10 minutes until set. Place cookies on wire cooling racks to cool before serving.
