I mean you have vapor milk, condensed milk and milk cream

You could repeat the ingredients but, it would still be a 3 leches dessert

Unless… WAIT A MINUTE

You could technically add coconut milk, condensed coconut milk, which is also a thing that is totally real and exists, AND dulce de leche which for the layman sounds redundant, BUT the makeup is completely different to the other milk ingredients

It’s either that or some almond milk heresy, but in that case we would be talking about a real seis leches
