Why This Recipe Works

Rhubarb & Lemon Curd Cake balances acidity and sweetness to perfection. The self-raising flour provides lift, while the ground almonds create a subtle nuttiness that complements the fruit. Eggs add richness without overwhelming the delicate lemon curd topping. This cake is ideal for beginners due to its forgiving structure and shorter baking time compared to traditional layered desserts.

Ingredients

Ingredient	Quantity	Notes
Unsalted butter	225g (softened)	Use room temperature butter for smooth creaming
Caster sugar	225g	Granulated sugar may work but won’t dissolve as easily
Lemon zest	1 lemon	Grate with a microplane to avoid white pith
Eggs	4	Beaten and added gradually for aeration
Ground almonds	75g	Omit for a gluten-free version but mix thoroughly to avoid curdling

Step-by-Step Instructions

Preparation

Preheat oven to 180°C/160°C fan/Gas 4.
Butter and line a 20cm deep cake tin with parchment paper.

Customizing the Cake

Beat softened butter, caster sugar, and lemon zest until light and fluffy using an electric whisk.
Add eggs in batches, beating after each addition. If curdled, beat in ground almonds to stabilize.
Fold in ground almonds and flour. Combine half the rhubarb with batter first.

Baking Process

Transfer mixture to prepared tin, scatter remaining rhubarb, and top with demerara sugar.
Bake for 45–60 mins until a skewer inserted into the center comes out clean.
Allow to cool completely in tin before removing.

Topping Preparation

Whip double cream until soft peaks form. Loosen lemon curd with water, then fold gently into cream.
Spread the mixture over cooled cake and drizzle with additional lemon curd.

Chef Tips for Perfect Results

Use forced rhubarb for tender texture—look for thinner stalks with white tips in early spring.
Room temperature eggs blend more evenly into butter-sugar mixture. Set eggs out for 30 mins before mixing.
To fix curdled batter, beat in ground almonds first or add 1–2 tbsp water to stabilize emulsion.
Test doneness with a skewer rather than pressing cake—internal moisture affects elasticity without true doneness.

Common Mistakes to Avoid

Overbaking: Cakes may dry out quickly. Start checking at 45 mins. Internal temperature should be 99°C (200°F).
Using cold butter: Cold butter prevents proper creaming. Allow hishe base, room temp butter is essential for fluffy texture.
Omitting ground almonds: They stabilize the egg mixture. If excluded, add 2–3 tbsp flour or buttermilk.

Variations and Substitutions

Ingredient	Substitution	Impact on Flavor
Ground almonds	Plain flour	Will create a denser, richer cake
Lemon curd	Lemon zest + more sugar (2 tbsp)	More acidic but less luxurious topping
Unsalted butter	Coconut oil (melted)	Imparts distinct flavor not suitable for lemon curd contrast

Frequently Asked Questions

Can I use frozen rhubarb?

No. Frozen rhubarb releases excess moisture as it thaws, making the cake soggy. Use tailored rhubarb in peak season instead.

How to tell if cake is done?

Insert a skewer into the center. If it comes out clean with no damp batter, it’s done. Internal temperature should reach 99°C (200°F).

Curdled batter—what should I do?

Add 1 tbsp ground almonds to affected mixture and continue beating. If still separated, mix in 1–2 tbsp water to stabilize emulsion.

Can this cake be made ahead?

Yes. Bake and cool the cake, then refrigerate in airtight container for up to 3 days before adding toppings the same day.

Best serving temperature?

At room temperature after refrigeration. This allows the lemon curd topping to set properly while keeping the sponge tender.
