Use your favorite ice cream in place of the spumoni. Try Neapolitan; it has equal parts of chocolate, vanilla and strawberry, or try a single flavor.
Hot fudge ice cream topping varies in consistency. Choose spreadable hot fudge for this recipe. Use room temperature topping and stir it until the texture softens enough to spread.
Put this dazzling dessert together up to three days ahead. For easier slicing after long freezing, let the dessert soften in the refrigerator for 30 minutes before serving.
