To make these Oreo Crust Mini Cheesecake Bites gluten free, use certified gluten-free chocolate sandwich cookies in place of regular Oreos, since traditional Oreos are not gluten free in all varieties and regions. Be sure to check the labels on the cream cheese, vanilla extract, and any whipped topping you may use, as ingredient formulations can vary by brand. Also confirm that all ingredients are prepared in a gluten-free facility if cross-contact is a concern. Once you make that simple swap, these mini cheesecake bites are very easy to adapt for a gluten-free dessert.
