Easy, Delicious, Rhubarb Crumble in Cake form... What could be better than Rhubarb Crumble Cake?!
Preheat your oven to 190C/170C and line a 9" Square Tin with parchment paper.
Beat together your Butter and Sugar together till light and fluffy.
Add in the Flour, Eggs and Vanilla and beat again till smooth.
Mix your chopped up rhubarb (about inch size pieces) with the other 50g of Sugar, and then pour half into the cake mixture. Mix together and pour into the tin!
Put the rest of the rhubarb on top of the cake evenly, and then cover with your crumble mixture! You want it to be no more than 1cm thick otherwise it wont bake properly!
Bake the cake in the oven for 30-40 minutes. It shouldn't wobble when done, and the crumble should be a lovely colour on top!
Leave to cool fully, cut up into squares, and then serve how you like!
