Castella Cake: the easy Japanese recipe for a fluffy dessert

A delicious cake made with only a handful of ingredients? Yes, it can be done! This Castella Cake is an easy Japanese sponge cake, made with flour, sugar, eggs, milk, and honey. It’s also known by its other name, Kasutera. It’s a super light and fluffy cake sweetened with honey. The cake is said to have been introduced in the Nagasaki area (back in the 16th century), by Portuguese merchants.
