Rhubarb Crumble Traybake Cake 🍰🍂🌸
The first time I baked this rhubarb traybake, it was on one of those blustery spring afternoons when the weather couldn’t decide between sunshine and rain. I’d brought home a bundle of rhubarb from the market — its pink stalks so bright they almost seemed to glow in the basket. I wasn’t planning on baking, but the idea of a warm, golden sponge with a crunchy crumble topping felt too good to resist. As it baked, the house filled with that buttery-sweet scent, and by the time I pulled it out of the oven, I knew it was one of those bakes that would become a favourite. A slice with a hot cup of tea, the rain tapping at the window — it felt like the perfect little pause in the day. Now, every time I make it, it feels like stealing back that same cosy moment.
Ingredients
🥚 Eggs: 3, large
🧈 Unsalted butter: 200g, softened
🍬 Caster sugar: 200g
🌾 Self-raising flour: 200g
🥛 Whole milk: 2 tbsp
🌸 Fresh rhubarb: 300g, chopped into small chunks
For the crumble topping
🌾 Plain flour: 100g
🍬 Light brown sugar: 50g
🧈 Unsalted butter: 75g, chilled and cubed
🍬 Demerara sugar: 1 tbsp (for sprinkling)
Method
🔥 Preheat the oven to 180°C (fan 160°C). Grease and line a rectangular baking tin (about 30 x 20cm).
🥄 Cream the butter and caster sugar until pale and fluffy — just like Nan always said, “keep going until it looks like clouds.”
🥚 Beat in the eggs one at a time, mixing well after each addition.
🌾 Fold in the self-raising flour gently, then stir through the milk to loosen the mixture.
🍰 Spread the sponge mixture evenly into the tin, then scatter the rhubarb chunks on top, pressing them in slightly so they nestle into the batter.
For the crumble topping
🥣 Rub the chilled butter into the flour with your fingertips until it resembles breadcrumbs. Stir in the light brown sugar.
🥄 Sprinkle the crumble topping evenly over the rhubarb, then finish with demerara sugar for extra crunch.
🔥 Bake for 40–45 minutes, until the sponge is golden, the rhubarb tender, and the crumble crisp.
⏳ Leave to cool in the tin before cutting into generous squares — though truth be told, it’s impossible not to steal a warm slice straight away.
