To make this pie gluten-free, swap the graham cracker crust with a gluten-free version. Look for gluten-free graham crackers or use crushed gluten-free cookies as the base—they work just as well and add great texture! Just make sure to check all other ingredients, especially things like whipped cream cheese and coconut, for any sneaky gluten additives. With a few swaps, this tropical pie is ready for everyone to enjoy, gluten-free and delicious!
