Sieve the flour, Baking Powder and ground almonds over the mixture and fold through until just combined.


Pour the sponge mixture in the prepared tin and smooth to evenly cover the base. Spread the rhubarb on top to create an even layer of rhubarb. Finally Sprinkle the crumble topping over the rhubarb ensuring it is completely covered.
