- 50 g plain flour
- 50 g golden caster sugar
- 0.5 tsp ground ginger
- 50 g unsalted butter chilled
- 25 g rolled oats
Rhubarb Filling
- 300 g rhubarb trimmed, rinsed and cut into 2.5cm pieces
- 25 g golden caster sugar
- 1 orange zested
Vanilla Cake
- 100 g unsalted butter room temperature
- 200 g golden caster sugar
- 1 orange zested
- 2 eggs large
- 200 g plain flour
- 2 tsp baking powder
- 1 tsp vanilla essence
- 150 ml sour cream
Instructions
- Heat oven to 180C/160C fan/gas 4. Grease a deep 20cm round cake tin and line the base with baking parchment.
- To make the crumble topping, put the flour, sugar and ginger in a bowl and mix together. Add the butter and rub together until the mixture resembles breadcrumbs. Stir in the oats and, using your hands, bring the mixture together into a dough, wrap in cling film and chill until needed.
- Put the rhubarb pieces in a bowl with the sugar and orange zest, and mix together. Set aside while you make the cake batter.
- Put the butter, sugar and orange zest in a large bowl and, using an electric whisk, beat together until light and fluffy, about 5 mins. Add the eggs, one at a time, beating together until combined before adding the next.
- In a separate bowl, mix the flour, baking powder, vanilla paste and a pinch of salt together and, in two additions, fold into the butter mixture, alternating with the soured cream. Tip into your cake tin and level out with a spatula. Top with the rhubarb mixture and finish by breaking the chilled crumble into irregular-sized pieces and scattering over the rhubarb. Bake in the oven for about 1 hr 10 mins or until the crumble is golden and a skewer inserted into the middle of the cake comes out clean. Check the cake after 1 hr – if it is colouring too quickly, cover lightly with foil for the final 10 mins.
- Allow to cool in the tin for 10 mins before carefully transferring onto a wire rack to cool completely. Will keep in an airtight container for up to 3 days, but the crumble will lose some of its texture after the first day.
