Special Baking Tips for Cake Mix Peanut Butter Cookies

  • You can use any brand of yellow cake mix for this cookie recipe.
  • If you choose to make cookies bigger than 1-inch balls, be sure to bake them a minute or two longer (adding about one minute for every extra ¼ inch) so they set when cooled. More dough requires more baking time.
  • For a fun variation, add 1 cup coarsely chopped peanuts to the cookie dough just before rolling into balls.
  • Make this recipe into sandwich cookies. Spread 1-2 teaspoons chocolate frosting onto the flat surface of one cookie. Press another cookie on top.
