To make this Creamy and Dreamy Pineapple Cheesecake gluten free, replace the regular graham cracker crust with a certified gluten-free graham cracker crust or a homemade crust made with gluten-free graham-style crumbs. Confirm that the cream cheese, sugar, whipped topping, canned crushed pineapple, whipped cream, cherries, and pineapple garnish are gluten free and processed without gluten cross-contamination. If using store-bought garnish or canned fruit, review labels carefully for gluten-containing additives.
