Could three ingredients be used to create the perfect apple crisp cookie? Pinterest users boasted it could be done, so our kitchen experts put the idea to the test. To make the cookies we simply combined 1 pouch of Betty Crocker oatmeal cookie mix, ¼ cup of butter (softened), and 1 cup of apple pie filling (chopped). Then we set our cookies in the oven to bake at 350 degrees for about 15 minutes. The result? Unbelievably good cookies. Our humble recipe turned out to be a sweet success. Then we took it a step further and used the sweet and easy recipe to make a 3-Ingredient Apple Crisp Snack Cake!
