Cool Whip Cookies are so simple to make - only 4 ingredients (egg, powdered sugar, whipped topping, and cake mix) and ready in under 30 minutes! These rich, fudgy cookies can be made in lots of flavors, like lemon, chocolate, or strawberry.
Place coated cookies on a baking sheet lined with a silicone mat or parchment paper. Bake at 350 degrees for 9-11 minutes (less time for more fudgy cookies, more time for more cakey cookies).
Allow to cool on the baking sheet for 10-15 minutes before moving to a baking rack for cooling.
