Boozy Chocolate and Dulce de Leche Truffles

"These boozy truffles are extremely tempting and an explosion of flavors. They are a total treat for all chocolate and dulce de leche fans out there. They also include walnuts and a bit of whisky (totally optional), which makes them the perfect companion for a hot tea or coffee, or even an easy-to-make dessert for any kind of event."
