Latin America's most beloved celebration cake — a light sponge soaked in a mixture of three milks (evaporated milk, condensed milk, and cream) until saturated, then topped with whipped cream; improbably rich yet impossibly light.
The soaking method
The defining technique is soaking: a light, porous sponge (with some of the egg whites beaten separately to create air pockets) is baked and allowed to cool, then pierced all over with a fork or skewer. The three-milk mixture — evaporated milk, condensed milk, and heavy cream — is slowly poured over the entire surface and allowed to saturate the cake completely. The soaked cake is refrigerated for several hours or overnight.
Why it works
The sponge must be made with enough structure to absorb the milk mixture without disintegrating, but porous enough to hold the liquid. Génoise or a chiffon-style cake achieves this. The result is a cake that is wet through but not soggy — the fat in the cream and the proteins in the milk create a silky, custardy crumb that bears no resemblance to a conventionally dry sponge.
The three milks
- Evaporated milk — unsweetened concentrated milk with 60% water removed; provides protein and cream flavour
- Sweetened condensed milk — very thick, sweet, reduced milk; provides sweetness and richness
- Heavy cream — provides fat and body
Some recipes use whole milk instead of cream for a lighter result.
Latin American identity
The cake appears in most Latin American countries under slightly different names and variations. In Nicaragua and Mexico it is considered a national dessert. Nestle printed an early version of the recipe on condensed milk cans, which helped spread it across the region in the mid-20th century.
