Pastelillos de Guayaba! These Guava Paste Puff Pastries are not only delicious, but they are also really so simple to make. With just three ingredients you cannot go wrong. Soft, flaky, and tossed in powdered sugar. This Puerto Rican Pastelillos de Guayaba dessert is perfectly sweet and truly a treat. Best enjoyed as a dessert, snack or even for breakfast with coffee (a Puerto Rican favorite). Auténtico. Enjoy! ~ vegan ~ plant-based ~ dairy-free ~
