When it's done cooking and it's completely cooled, you poke a lot of holes in it with a fork.. all over it, so that the milks can set it. And then you pour in the milks (that you mix together first) which are
2 Cups whole milk
1 14 oz can sweetened condensed milk
1 12 oz can evaporated milk
While that's setting in, you can whip up the icing which is:
1 1/2 Cups heavy whipping cream
1 cup sugar
1 teaspoon vanilla (I used a little extra because I love vanilla flavor)
Smooth it on top..
I covered mine with slices of strawberries.
Keep it refrigerated until you serve it. It needs to stay cold, because of the milk.
What you get is a really moist, dense cake and it is delicious. It was one of my favorite things when I was pregnant.
Notes: Tres Leches is traditionally covered in whatever fruit you have on had. It also tastes amazing with a little bit of caramel drizzled over the top. This recipe tastes best when done with a white or other vanilla cake, though I have, on a very rare occasion, seen it made with chocolate cake. I'm not sure how that would taste though.
