Rhubarb and Custard Crumble Cake

Sweet custard sponge base, covered with a layer of sharp juicy rhubarb, topped with a pecan crumble.


It’s Rhubarb Season! Well only just, but I just couldn’t wait any longer, so here is my first rhubarb recipe; Rhubarb and Custard Crumble Cake.

I basically came up with this recipe because I wanted to make something with a combination of rhubarb and custard, but I also really wanted to make a rhubarb crumble. So, I thought I’d combine everything into one recipe, and it has turned out brilliantly!

The sponge is deliciously moist with a lovely custardy flavour that perfectly complements the sharp rhubarb, and the pecan nut crumble adds a much needed crunchy finish. This is a wonderfully comforting pudding, making a great family dessert.

Variations: The rhubarb could be swapped for other fruits such as apple or raspberry.
