Turn our delicious Grinch Cookies into a gluten-free version without losing any of their festive appeal! Just substitute the white cake mix with your gluten-free cake mix. These special mixes are created to imitate the texture and taste of cake mixes ensuring that your cookies still maintain that fluffy goodness we all adore. Remember, gluten-free flours may absorb moisture differently so if your dough feels a bit dry feel free to add a splash of milk or water until you achieve the desired consistency.
