Rhubarb and marzipan crumble cake

It’s been over a month since I last wrote a post! To be honest, I haven’t baked much until recently – I was away for much of July and the hot weather meant that it was just too hot to be stuck in the kitchen with the oven going! However, the gorgeous July weather also meant that my rhubarb kept on growing and I did need to bake something to use it up again!

Having not been particularly impressed with the rhubarb and custard cake I made last time, I decided to have a go at a different rhubarb recipe this time: rhubarb and marzipan crumble cake. I found this recipe recommended online and the only change that I made was the addition of the chopped hazelnuts. I love the crunch and the flavour that chopped hazelnuts give to the crumble mixture on my rhubarb crumble muffins and so decided that they would also be a great addition to this recipe.

This recipe is a definite hit! When making, there seemed to be an imbalance between the relatively small amount of cake, reasonable amount of rhubarb and huge amount of crumble, however, once baked, it turned out beautifully. The cake is deliciously moist and fairly tart and the crumble on top is crunchy and sweet. I took this cake into work and it went down a storm! Definitely one that I will be making again!

Update August 2014
Made this delicious cake again last week and I added 15 drops of Lakeland custard flavouring, which added a delicious sweetness to the cake. The cake took a very long time to cook and was very moist still in the middle. I think that the rhubarb gave out too much juice while cooking and so it would probably be a good idea to draw out some of the juices first. I have adapted the recipe below to suggest this. 

Rhubarb and marzipan crumble cake

Ingredients

1. 150g plain flour
2. 125g butter
3. 25g light muscovado sugar
4. 40g chopped hazelnuts
5. 100g marzipan, coarsely grated
6. 100g golden caster sugar
7. 2 free range medium eggs
8. 1tsp baking powder
9. 400g rhubarb, washed & sliced
10. 15 drops custard flavouring (optional)
11. Custard or clotted cream to serve

Method

1. Place the chopped rhubarb in a bowl and coat with 25g caster sugar. 
2. Preheat the oven to 190C.
3. Grease and base line a 20cm deep, loose bottomed cake tin.
4. Prepare the crumble topping: sift half the flour into a bowl and rub in 50g of the butter. Stir in the muscovado sugar, hazelnuts and the marzipan, then set aside.
5. Cream the remaining 75g butter with 75g of the caster sugar until pale.
6. Beat in the eggs, one at a time.
7. Sift in the remaining 75g flour with the baking powder and fold in quickly to form a soft batter.
8. Spoon into the prepared cake tin, and spread level.
9. Tip the rhubarb into a sieve to drain away any juices and then scatter the rhubarb onto the creamed mixture.
10. Sprinkle the crumble on top to cover.
11. Bake for 45 minutes, until the top is golden and springy.
12. Allow the cake to cool for 10 minutes and then remove from the tin.
13. Serve slices warm or cold with custard or clotted cream.
