Making our Salted Caramel Icebox Cake using gluten-free ingredients is incredibly easy and allows those, with gluten sensitivities to indulge in its deliciousness. The trick is to replace the Ritz crackers with a gluten-free option. Luckily there are brands that offer crackers with the same buttery flavor and crispy texture as Ritz minus the gluten. Just choose your brand of gluten-free crackers that provide a similar texture and buttery taste.
