A tres leches cake during the summer is a delight. For a cake made of three milks – evaporated, condensed and fresh whole – this Latin American classic is surprisingly refreshing. Whenever I crave it, my mind wanders to my friend Terri Mercieca’s [founder of Happy Endings] creation: the tres leches ice-cream sandwich. Picture a delicate yellow sponge cake embracing layers of ice-cream and decadent dulce de leche. It’s a knockout quick fix! Or for a bit more of a project, make today’s recipe.
