Wow! Jodie of beansylovescake picked a winner with these part crispy, part cake-like cookie sandwiches filled with creamy tantalizing dulce de leche, literally “milk candy” in Spanish. Dulce de Leche is available at many grocery stores which carry a large selection of Spanish and Mexican foods. It is easily made from scratch using sweetened condensed milk, but is time-consuming. I froze most of my cookies before filling them, but the filled cookies keep well covered at room temperature for several days making them perfect for entertaining.Jodie has the recipe on her blog, but also check out the TWD blogroll for other variations of this perfectly delicious cookie.
