Why This Recipe Works
Rhubarb & Lemon Curd Cake relies on a simple ingredient trio: butter, sugar, and gluten-free ground almonds. The trick lies in the rhubarb’s preparation—cutting it into 1-2cm chunks ensures even baking without overpowering the delicate cake body. The lemon curd topping glides across rooms with its bright aroma, making this recipe ideal for spring brunches.
The cake’s texture is worth perfecting. By starting with softened butter and beating it until light and fluffy, then gradually adding room-temperature eggs, you create a stable base that resists curdling. When the flour and almonds are folded in gently, the batter retains its aeration while incorporating the rhubarb like a fresh compote.

Step-by-Step Instructions
Prepare the Tin
- Heat oven to 180°C/160°C Fan/Gas 4
- Butter a 20cm round cake tin and line base with parchment
- Whisk flour and ground almonds for even distribution
Mix the Batter
- Beat butter until light and fluffy (2-3 minutes)
- Add caster sugar and lemon zest, beat 1-2 minutes
- Gradually add eggs one at a time, beating each fully
- Stop if batter curdles – beat in 1 spoonful almonds
- Add ground almond mixture, gently fold in flour
Assemble and Bake
- Fold in half the rhubarb chunks gently
- Transfer to tin, top with remaining rhubarb
- Scatter with demerara sugar for crust
- Bake 45-60 minutes until skewer comes out clean
- Cool in tin 10 minutes before releasing
Make the Topping
- Whip double cream until soft peaks form
- Loosen lemon curd with 1 tbsp water
- Fold into cream without overmixing
- Spread over cooled cake
- Drizzle with extra lemon curd
Chef Tips for Perfect Results
- Taste rhubarb raw beforehand – tartness varies by harvest
- Don’t overmix batter after adding flour – preserves airiness
- Probing cake frequently extends cooking time – check last 10 mins
- Freeze unbaked cake version in tin with parchment sleeve
- For nighttime baking, cover with tent of parchment during final 20 mins
Common Mistakes to Avoid
- Adding rhubarb too large: Cuts need <1cm chunks for even cooking. Fix: Pulse in food processor.
- Curling cream layer: Overfolding curd breaks emulsion. Fix: Fold in 3 gentle stages.
- Hard cake top: Overbaking creates dry crust. Fix: Cover with foil in last 10 mins.
- Sunken center: Shrinkage happens with cold ingredients. Fix: Keep batter at room temperature.
- Cracked topping: Serve cake at room temperature, not cold from fridge.
Variations and Substitutions
| Ingredient | Substitution | Impact on Flavor |
|---|---|---|
| Forced rhubarb | Gooseberries or sour cherries | Increases tart contrast to lemon curd |
| Butter | Olive oil (1:1 ratio) | Adds savory undertone, reduce sugar by 20g |
| Ground almonds | Coconut flour (1/3 cup) | Creates denser, coconut-infused texture |
| Double cream | Whipping cream (with thickener) | May weep slightly if not stabilized |
Serving Suggestions and Pairings

Frequently Asked Questions
Can I use store-bought lemon curd?
Yes, quality counts. Look for curd with 60-65% juice content and low sugar for balanced flavor.
How do I tell when the cake is done?
Insert a cake tester: if it comes out clean but slightly sticky with wet crumbs, it’s done. Rhubarb’s moisture allows for slightly undercooked center.
My batter curdled! Is it salvageable?
Yes, stop beating and add 1-2 spoonfuls ground almonds. Let sit 30 seconds before resuming at low speed.
Can I make this 1 day ahead?
Yes, bake, cool completely, spread curd topping, then refrigerate wrapped in parchment. Topping may weep slightly, so re-whip cream layer before serving.
What if I don’t have a 20cm tin?
Use 2x 18cm tins. Divide batter equally, bake 35-40 mins. Double the lemon curd topping for叠加 effect.
No pork, ham, or alcohol used in this recipe. Gluten-free substitution instructions provided in ingredients table.
