Food blogger Jo Cooks has translated this recipe for a ‘Magic Custard Cake’, which goes into the oven as a single batter but bakes into a three-layer cake with a crunchy top layer, a set layer in the middle and a runny custard base.
The blogger Joanna Cismaru (Jo Cooks) posted the cake on Instagram and it has taken off. The recipe is much like a Basque cheesecake and Cismaru discovered it online some years ago, but couldn’t find an English version, so she translated it.
Using just six ingredients, the Magic Custard Cake is so easy to make. Just about anyone can do it, and so they are, with many people posting their efforts to Instagram and Tik Tok.
The ingredients couldn't be more simple: four eggs (separated), 150g caster sugar, 1 tsp vanilla extract, 125g unsalted butter, 115g plain flour, 500ml milk.
You can make your own variants by adding your own flavourings, but it’s hard to beat the original vanilla.
To make sure you get the three layers in the Magic Custard Cake, a trick is to not fold in the egg whites completely, instead make sure some of the white bits remain. That’s the only tip though, the rest is straight forward.
