A Tres leches cake, or Pastel e Tres leches (Spanish, "Three milk cake"), is a cake,—in some recipes, a butter cake—soaked in three kinds of milk: evaporated milk, condensed milk, and either whole milk or cream. When butter is not used, the tres leches is a very light cake, with many air bubbles. This distinct texture is why it does not have a soggy consistency, despite being soaked in a mixture of three types of milk.
