Tres Leches de Coco (Coconut Tres Leches Cake)
To toast the coconut for the topping, arrange it in a single layer in a large baking sheet. Bake 5 to 10 minutes on the center rack of a preheated 350°F oven, stirring the coconut halfway through baking, until crisp and golden. Transfer baking sheet to cooling rack and cool coconut completely, about 15 minutes.
It will look like there is too much liquid for the cake, but it is one thirsty sponge! Add the milk mixture to the cake about 1/2 cup at a time, one section of the cake at a time to ensure even absorption.
