Arroz con leche is a sweet and creamy Mexican rice pudding lightly infused with cinnamon that both kids and grown-ups love. This version is extra creamy because it is made tres leches–style, with three types of milk: whole, evaporated, and sweetened condensed. Using the Instant Pot® for this classic Mexican dessert makes it even easier to enjoy with no hassle at all. Just mix in the ingredients, cover the pot, press start, and forget about it.
