Let me start by saying that not all caramel candies are created equal! I learned this the hard way when I was working on a previous cookie recipe. The best caramel candies to use for this recipe is the Werther’s brand Soft Caramels. They are so soft and creamy! Kraft caramel squares are much firmer and harder so they won’t create a gooey caramel center. Keep in mind that the type of caramel candy you use definitely matters. If you’re using Werther’s brand, fold them in half because they are pretty long and may not fit inside the cookie dough ball and could possibly cause the caramel to ooze out the side.
