This is my Biscoff version of tres leches, the soft Latin American sponge that gets soaked in three milks until it is almost spoonable. I keep the classic bones of the cake and then run Biscoff through every layer, so you get that warm caramelised, slightly cinnamony speculoos flavour in the soak, in the topping, and crumbled on top. If you have ever had cookie butter on toast and wished it could be a cake, this is that wish.
The method is the same friendly one that makes tres leches so forgiving. You bake a light sponge, poke it all over while it is still warm, and pour over a mix of evaporated milk, sweetened condensed milk, and cream that I loosen with melted Biscoff spread. The cake drinks it in overnight and turns dense and custardy without ever going to mush. The top is whipped cream and a final scatter of crushed Biscoff biscuits.
It is a make-ahead dream, which is half the reason I love it. You do the work the day before, it sits in the fridge getting better, and all you do before serving is slice and crumble. It feeds a crowd, it travels in its own dish, and the Biscoff makes people ask what is in it before they have even finished the first bite.
