Transforming this indulgent Caramel Slice into a gluten-free delight is surprisingly simple and doesn’t compromise on its delectable layers of pleasure. Start by swapping the plain flour in the base for your favorite gluten-free all-purpose flour blend. Ensure that it’s a 1:1 substitute to maintain the recipe's integrity. For an added twist and to enhance the texture, consider incorporating a tablespoon of almond meal, which not only contributes a lovely nutty undertone but also adds to the base’s richness. This small tweak not only assembles the recipe unrestricted for those with gluten sensitivities but also presents fun new proportions to the classic delight.
