Delia Smith Lemon Drizzle Cake Recipe

This Delia Smith lemon drizzle cake is made with four lemons, golden caster sugar, poppy seeds, and a double syrup that soaks through the sponge. The result is a sticky, crunchy-topped cake that stays moist for days. It serves 10 and takes about 55 minutes from start to finish.

I make this in a Silverwood loose-based tin every time I need a reliable cake for a gathering. The sugar crust on top is what sets Delia’s version apart from every other lemon drizzle recipe out there.

Lemon Drizzle Cake Ingredients

For the Cake

• 175g self-raising flour
• 1 teaspoon baking powder
• 175g spreadable butter
• 175g golden caster sugar
• 3 large eggs
• Grated zest of 3 large lemons
• Juice of 1 large lemon
• 40g poppy seeds

For the Syrup

• Juice of 3 large lemons
• Grated zest of 1 large lemon
• 50g golden icing sugar, sifted
• 100g golden granulated sugar

To Finish

• 1 rounded teaspoon golden granulated sugar
• 1 rounded teaspoon poppy seeds

What You’ll Need

You will need a 20cm round loose-based cake tin for this recipe. A Silverwood anodised aluminium tin distributes heat evenly and lasts decades, which matters for a sponge that needs a consistent bake across the top.

A Microplane zester handles the four lemons cleanly, with no bitter pith. For mixing, a KitchenAid hand mixer on medium speed brings the all-in-one batter together in about a minute.

How to Make Lemon Drizzle Cake

1. Preheat and prepare the tin: Set the oven to 170°C (Gas Mark 3). Grease a 20cm round loose-based cake tin and line the base with baking parchment.
2. Sift the flour from a height: Sift the flour and baking powder into a roomy mixing bowl, holding the sieve quite high. This is Delia’s signature technique for incorporating extra air into the flour before it touches the wet ingredients.
3. Mix the batter: Add the butter, golden caster sugar, eggs, lemon zest (from 3 lemons), lemon juice (from 1 lemon), and poppy seeds. Whisk with a KitchenAid hand mixer on medium speed for about one minute until smooth and creamy.
4. Bake the sponge: Spoon the mixture into the prepared tin, levelling it with the back of the spoon. Bake near the centre of the oven for 40 minutes, or until the centre feels springy to the touch.
5. Make the syrup while it bakes: In a small bowl, mix the juice of 3 lemons, the zest of 1 lemon, 50g sifted golden icing sugar, and 100g golden granulated sugar. Do not dissolve the sugar fully.
6. Drizzle the hot cake: Remove the tin from the oven onto a board. Immediately stab the hot cake all over with a skewer, then spoon the syrup evenly over the surface. The granulated sugar staying partially undissolved is what creates the crunchy crust.
7. Finish and cool completely: Mix the rounded teaspoon of golden granulated sugar with the remaining poppy seeds and sprinkle over the top. Let the cake cool completely in its tin before removing. The syrup makes it fragile while warm.

What Makes This Lemon Drizzle Cake So Good?

• Sift from a height: Delia insists on holding the sieve high above the bowl. This pulls extra air into the flour before mixing, giving the sponge a noticeably lighter texture.
• Drizzle while piping hot: The syrup must go on while the cake is still hot from the oven. Hot sponge absorbs liquid like a sponge. Cold sponge lets it pool on top.
• Leave the sugar grainy: Do not stir the syrup until the sugar dissolves. The undissolved granules are what create the signature crunchy crust as the cake cools.
• Cool completely in the tin: The syrup makes the cake fragile while warm. Trying to remove it too early will cause it to crumble. Patience here is everything.
• Test by pressing the centre: Forget toothpicks. Press the centre gently with your finger. If it springs back immediately, it is done. If your finger leaves a dent, give it a few more minutes.
• Warm your lemons first: Roll each lemon firmly on the worktop before juicing, or microwave for 10 seconds. A Microplane Premium Classic zester gives you fine, fluffy zest with no bitter pith. For a recipe using four lemons, both steps make a real difference.
• Watch for sinking: If your cake sinks in the middle, the most common cause is too much baking powder or opening the oven too early. Use a level teaspoon and avoid checking before 35 minutes. The same rule applies to other Delia lemon sponge cakes.

What Goes Well with This Cake?

This is a proper afternoon tea cake. Serve it with a pot of English Breakfast tea and nothing else, and it will hold its own. The crunchy sugar top and sticky lemon sponge are satisfying enough on their own.

For something more dressed up, add a spoonful of crème fraîche or thick double cream on the side. Fresh raspberries or strawberries work well too, especially in summer. It also suits a bake sale or village fete, as the slices travel well and hold together once fully cooled.

If you are planning an afternoon tea spread, pair it with a Delia Smith Victoria sponge for contrast. One citrus, one classic vanilla. They complement each other perfectly.

How Should I Store This Cake?

Once completely cool, remove the cake from the tin and transfer it to an airtight container or cake tin. It keeps beautifully moist at room temperature for 3 to 4 days. The syrup acts as a natural preservative, so it actually tastes better on day two than on day one.

To freeze, wrap the whole cake or individual slices tightly in a double layer of cling film, then cover with foil. It freezes well for up to one month. Thaw at room temperature for 2 to 3 hours before serving.

The crunchy sugar topping softens slightly after freezing, but the flavour stays just as good. If you love Delia’s lemon bakes, her homemade lemon curd also freezes brilliantly.

Can I Swap or Skip Any Ingredients?

Delia herself notes that this cake is equally good without the poppy seeds. Simply leave them out of both the batter and the topping. The cake will have a smoother texture, but the flavour and moisture stay the same.

For the butter, spreadable butter is specified because it creams easily with the all-in-one method. You can use softened unsalted butter instead, but make sure it is genuinely soft, not just taken out of the fridge. Cold butter will not mix smoothly.

For the syrup, golden icing sugar gives a slightly richer taste than white, but regular icing sugar works fine. The golden granulated sugar is more important, as it creates the crunch. Do not swap it for caster sugar.

For a gluten-free version, replace the self-raising flour with a gluten-free self-raising blend. Check that your blend contains xanthan gum for the right texture. If you want a lighter sponge altogether, try Delia’s fatless sponge as a starting point.
