These little bites of pastry filled with dulce de leche are a special treat. We like to make pastelitos de dulce de leche when we have leftover scraps of pastry dough. Especially after rolling out a pie crust. But they are so delicious you will want to make a whole batch of pastry dough dedicated only to these little cookies. It's difficult to keep the dulce de leche from leaking out during baking, but don't worry about it. When the leaking dulce de leche pools around the pastries in the oven, it gives them a delicious candy crunch on the bottom.
