Why, of course you can! White chocolate and strawberry is a lovely combination. You can use milk chocolate chips instead of dark. Or maybe you have a hankering for a PB&J cookie, so you use peanut butter chips instead. If none of those appeal to you, look to nuts, dried fruits or even candies as inspiration. Freeze dried banana, Reese's Pieces, or dried strawberries all sound delicious to me. These cake mix cookies are infinitely adaptable to your tastes, so have fun!
