To make this recipe gluten free, replace the vanilla-flavored wafers with certified gluten-free vanilla cookies or wafers. Also confirm that the white chocolate chips, orange marmalade, candy melts, corn syrup, and tequila are labeled gluten free or free from cross-contact concerns, since packaged products can vary by brand. Almond flour is naturally gluten free, but it is still a good idea to verify packaging if you are serving someone with celiac disease or a strong gluten sensitivity. If preparing these in a shared kitchen, use clean bowls, utensils, parchment paper, and work surfaces to avoid cross-contact.
