How Do You Make a Lemon Drizzle Loaf Cake?
A lemon drizzle loaf cake is a lemon-zested butter sponge baked in a loaf tin, then soaked while still warm with a sharp syrup of lemon juice and granulated sugar. Cream 175g each of butter and caster sugar, beat in 3 large eggs, fold in 175g self-raising flour with the zest of 2 lemons, and bake in a 900g (2lb) loaf tin at 180C (160C fan / 350F) for 45–55 minutes. Prick the hot cake all over and pour the drizzle on straight away.
That is the whole thing. The rest of this guide is about the two moments that decide whether it works: getting the middle baked through, and pouring the drizzle at the right time so it soaks in rather than sliding off.
What Goes Into the Cake and the Drizzle?
The cake is built on the same equal-weights idea as a Victoria sponge: butter, sugar and flour in matching amounts, with three eggs doing the binding. Keeping those three weights equal is what makes the recipe dependable, and it is why you can scale it up or down without guessing.
For the cake (one 900g / 2lb loaf, about 10 slices):
| Ingredient | Quantity | Notes |
|---|---|---|
| Butter | 175g | Softened to room temperature, plus a little for the tin |
| Caster sugar | 175g | Fine sugar creams faster than granulated |
| Eggs | 3 large | At room temperature |
| Self-raising flour | 175g | Or plain flour plus about 1½ tsp baking powder |
| Lemons | Finely grated zest of 2 | Unwaxed if you can get them |
| Salt | A pinch | |
| Milk | About 2 tbsp | Only enough to loosen the batter |
For the drizzle:
- Juice of 1½ lemons (save the zested lemons for this)
- 100g granulated sugar
Why granulated sugar for the drizzle? It does not fully dissolve in the juice. The juice soaks down into the crumb and the undissolved crystals stay on top, setting into the thin, crackly lemon crust that makes this cake what it is. Icing sugar dissolves completely and gives a smooth glaze instead, which is a different cake.
If you swap plain flour for self-raising, the 1½ teaspoons sits inside the range Food Network's baking guide gives: "1 to 1 1/4 teaspoon baking powder or 1/4 teaspoon baking soda per cup of flour." More than that is not extra insurance. It is one of the main reasons a loaf sinks.
How Do You Make It, Step by Step?
1. Get the tin and oven ready. Heat the oven to 180C (160C fan / 350F). Grease a 900g (2lb) loaf tin and line it with a strip of baking parchment long enough to hang over both long sides, so you can lift the cake out later.
2. Cream the butter and sugar. Beat the softened butter, caster sugar and lemon zest together for 3–4 minutes, until pale and fluffy. Rubbing the zest into the sugar first releases more of its oil.
3. Add the eggs one at a time. Beat each egg in fully before adding the next. If the mixture starts to look curdled, add a spoonful of the flour with the next egg.
4. Fold in the flour. Sift in the flour and salt and fold gently with a large metal spoon or spatula until no dry streaks remain. Add milk a tablespoon at a time until the batter drops off the spoon in a soft, thick dollop. Stop as soon as it is combined.
5. Bake. Scrape the batter into the tin and level it. Bake for 45–55 minutes, and do not open the door for the first 35 minutes or so. A crack running along the top of a loaf cake is normal and expected: the outside sets before the middle has finished rising, and the middle pushes up through it.
6. Make the drizzle while it bakes. Stir the lemon juice and granulated sugar together in a jug. Do not heat it and do not try to dissolve the sugar. It should look gritty.
7. Prick and pour while hot. As soon as the cake comes out, prick it all over, right down into the crumb, with a skewer or cocktail stick, then spoon the drizzle slowly over the top, letting each spoonful sink in before adding the next. Leave the cake in the tin until completely cool.
The tin and the cake are oven-hot at this point. Keep oven gloves on, set the tin on a heatproof surface, and work over it there rather than holding it.
When Should You Pour the Drizzle: Warm or Cold?
Warm, and as close to straight out of the oven as you can manage. Paul Hollywood's lemon drizzle, published by The Splendid Table, puts it plainly: "The only thing to remember is to pour over the drizzle while the cake is still warm."
A hot, open crumb pulls liquid in through the holes you have made. Once it cools, the surface firms into a skin, and juice poured onto it pools and runs down the sides. Leaving the cake in its tin while it soaks matters too: the tin walls stop the syrup escaping, so it has nowhere to go but down into the cake.
How Do You Tell It Is Baked Through in the Middle?
A loaf cake is deep, and its centre is the last part to set. The top can look golden and finished while the middle is still raw batter, so check the inside, not the outside.
- Skewer test. Push a skewer into the centre of the loaf, all the way to the bottom. Food Network's guide says to look for "a clean skewer or one with moist crumbs attached" and to "push it all the way down to the bottom of the cake pan where there might be wet batter." Wet, shiny batter on the skewer means it needs longer.
- Thermometer. If you own an instant-read thermometer, it removes the guesswork. Kansas State University Extension's doneness guide lists "Pound cake - 210°F" and "Quick bread - 210°F" (about 99C), and adds that "It is still important to use visual clues to determine if a product is done."
- Touch and edges. The top should spring back when pressed lightly in the centre, and the cake should be just starting to pull away from the sides of the tin.
If the top is browning well before the middle is done, lay a loose sheet of foil over the tin for the last 10–15 minutes.
Why Did My Lemon Drizzle Cake Go Wrong?
The centre sank. Underbaking is the usual reason: the middle had not set when the cake came out, so it collapsed as it cooled. Food Network's guide calls testing with a cake tester "the ultimate insurance against underbaking." The other common causes it lists are too much raising agent, an oven running hot or cold (it notes ovens cycle by up to about 25°F either way, and recommends an oven thermometer), beating in too much air, and opening the door or turning the tin too early. Its advice is to wait until about three quarters of the way through the baking time before rotating anything.
The crumb is dry. Usually overbaking, or too much flour. Ten extra minutes in a loaf tin dries the edges well before you notice anything wrong. Weigh the flour rather than using cups, start checking at 45 minutes, and do not skip the drizzle, which puts moisture back into the crumb.
The drizzle ran off the top. The cake had cooled too far before you poured, the holes were too few or too shallow, or the syrup went on all at once. Pour onto a hot cake, prick deep and often, and go a spoonful at a time.
There is no crunchy crust. The sugar dissolved fully, either because the drizzle was heated or because icing sugar was used. Mix granulated sugar with cold juice, and pour it on without stirring until clear.
How Long Does It Keep, and What Do You Serve It With?
Wrapped well or kept in an airtight tin at room temperature, a lemon drizzle loaf stays good for 3–4 days. In our experience it slices more cleanly on day two, once the syrup has settled evenly through the crumb.
It is one of the easiest cakes to bring to an afternoon tea because it travels in its tin and needs no cream or filling. The sharp lemon suits a brisk black tea. If you want the pot to be as good as the cake, our guide to brewing tea properly covers temperatures and steeping times by type.
