It's hard for me to pass up a treat. So when Mariana, my coworker, returned from Brazil and came around with these dulce de leche cookies, my response was "yes please!". These are traditional, with the meringue coating. But it's a layer of dulce de leche sandwiched between two soft cookies. Dulce de leche is slowly heated sweetened milk. Heated to the point where it becomes caramelized and oh so good. Try one if you have the chance.
