Yes, the brands I use are certified gluten free. However, always check the brands you use first. I use Nestle milk chocolate chips and Jett Puff Marshmallows. Both check out to be gluten free. As well as the Eagle Brand Sweetened Condensed Milk. If your entertaining a group and someone has a gluten allergy or maybe just staying away from it altogether Instant Pot Hot Chocolate is a great option to serve. *Always, read labels of course!
