To ensure this caramel apple dip is gluten-free, confirm that all ingredient labels—particularly the caramel dip and toffee bits—are certified gluten-free. Most cream cheese and granulated sugar are naturally gluten-free, but always double-check packaging to avoid hidden gluten. Serve with gluten-free dippers such as apple slices, gluten-free graham crackers, or pretzels labeled gluten-free.
