- 20cm diameter springform or silicone cake tin
- baking paper
- tin foil
- roasting tray, ideally pyrex as it's inert to the oxalic acid from the rhubarb
- optional but helpful, dredging spoon
- optional but really helpful, large metal serving spoon
- two large mixing bowls
- two additional containers, one suitable for four eggs to be beaten in and the other to hold less than 500ml of dry ingredients
- a coffee or food grinder that you are willing to put almonds in, or buy the almonds pre-ground
- 600 g fresh rhubarb, in 2cm chunks
- 100 g demerara sugar
- 3 tsp ground ginger
- 1/2 juiced_fruit lemon juice
- 250 g unsalted butter
- 160 g self-raising flour
- 100 g oats, ideally jumbo
- 4 count medium eggs, beaten
- 100 g almonds, ground
- 1 pinch salt
Preheat the oven to gas mark 5 (200°C). Line the cake tin with baking paper.
This cake is made in four stages: A) roast the rhubarb, B) make the streusel, C) make the cake batter, and D) layer the products of A-C into the cake tin for baking.
- Spread the rhubarb evenly across the roasting dish.
- Splash the lemon juice evenly across the rhubarb.
- Mix 40g demerara sugar with 1 tsp ground ginger in the dry ingredients container and use the dredging spoon (or dessert spoon) to scatter the sugar-ginger mix across the rhubarb evenly. Retain the dry ingredients container for later use.
- Roast the rhubarb for 15 minutes until soft.
- Set the rhubarb aside and turn the oven down to gas mark 3 (170-°C).
- In one mixing bowl, rub 200g butter into 60g flour and the oats until it turns into small crumby lumps.
- Stir in the remaining 60g demerara sugar and set the mixing bowl aside.
- In the second mixing bowl, cream the remaining 200g butter and caster sugar together until the mixture is homogenous. I used a fork because I don't have an appropriate electric mixing tool.
- Add the beaten egg a little at a time, stirring well and beating the mixture to get air into it once all the egg is added. I used a fork for this.
- Fold in the remaining 100g flour, remaining 2tsp ginger, ground almonds, and salt until the mixture is homogenous. I used a large metal serving spoon for this, if you only have a dessert spoon you can use that but it will be harder to grip.
- Drain the rhubarb using a colander.
- Use the metal spoon you mixed the batter with to spread half of the batter evenly across the bottom of the cake tin.
- Scatter half of the streusel evenly into the cake tin.
- Scatter half of the rhubarb evenly into the cake tin.
- Spread the remaining batter on top of the layers in the cake tin and smooth it.
- Scatter most of the remaining streusel into the cake tin.
- Scatter the remaining rhubarb into the cake tin.
- Scatter the last of the streusel into the cake tin.
- Put the cake tin in the oven for one hour.
- Cover the cake tin with foil and return to the oven for one hour.
Serve warm or cold, with thick unflavoured yoghurt or vanilla icecream.
