These cookies are big and chewy with an aromatic blend of spices. The gingery bite of the cookies is a delicious contrast to the caramel sweetness of the ice cream. These are a great do-ahead dessert choice (my favorite kind) for a warm-weather family gathering, served along with Sticky Fingers Triple-Chocolate Ice-Cream Sandwiches. Children and adults will love them with equal zest. Feel free to substitute vanilla ice cream for the Dulce de Leche flavor here; just make sure to purchase the best brand of ice cream possible to go with your cookies.
