So have you heard of the magical creation that is the ‘crumble cake’? Well, until a few years back, neither had I. But upon hearing about it, there was no question that I had to create my own.
It turned out that taking a trusty sponge recipe and fusing it with the elements of a crumble works.
And, wow, does it fit perfectly with the change in season. A light fluffy sponge, a crispy crumble topping, little bite-size pieces of fresh, fragrant rhubarb smothered in the creaminess of the icing. Come on, what more could you want?!
The real beauty of the crumble cake is that it’s served cold. So you get all of the flavour of a crumble, but none of the warm stodginess that you prefer to keep to the colder months.
