This moist, citrusy Mary Berry Loaf Cake is made with fresh lemons, simple pantry staples, and is ready in just over an hour. The recipe features a signature crunchy sugary topping that sets as the warm syrup soaks deep into the sponge. I love making this for a reliable weekend treat that fills the kitchen with a bright, welcoming aroma.

Why This Classic Works

I have baked countless lemon cakes, but this specific method stands out because of its foolproof all-in-one technique. Unlike recipes that require creaming butter and sugar separately, Mary Berry’s approach throws everything into the bowl at once, yet still yields a wonderfully light crumb. The first time I tried it, I was sceptical that such a quick method could produce a level rise, but the added baking powder ensures it lifts perfectly every time.

The real secret, however, lies in the timing of the drizzle. I learned the hard way that you must pour the syrup over the cake while it is still warm from the oven. If you wait until it cools, the syrup sits on top and makes a sticky mess; pour it while hot, and the sponge drinks up the lemon juice while the granulated sugar stays on the surface for that essential crunch.

Mary Berry Loaf Cake Ingredients

225g unsalted butter, softened
225g caster sugar
225g self-raising flour
2 tsp baking powder
4 large eggs
4 tbsp milk
Zest of 2 lemons (finely grated)

For the Crunchy Drizzle:

175g granulated sugar (not caster, for the crunch)
Juice of 2 lemons

How To Make Mary Berry Loaf Cake

Prep the Tin: Preheat your oven to 160°C Fan (180°C conventional / Gas 4). Grease a 900g (2lb) loaf tin and line the base and sides with baking parchment.
Mix the Batter: Place the softened butter, caster sugar, self-raising flour, baking powder, eggs, milk, and lemon zest into a large mixing bowl. Beat with an electric hand mixer for about 2 minutes until the mixture is smooth and pale.
Fill the Tin: Spoon the batter into the prepared loaf tin and level the surface gently with a spatula.
Bake the Loaf: Bake in the centre of the oven for 60 to 70 minutes. Check after 50 minutes; if the top is browning too quickly, cover loosely with foil. The cake is ready when it is golden, risen, and a skewer inserted into the centre comes out clean.
Make the Drizzle: While the cake is baking, mix the granulated sugar and lemon juice in a small bowl. The consistency should be runny but grainy.
Drizzle and Cool: Remove the cake from the oven and immediately prick the surface all over with a skewer or cocktail stick. Pour the lemon mixture evenly over the hot cake. Leave it to cool completely in the tin before lifting it out.

Recipe Tips

Room Temperature Ingredients: Ensure your butter and eggs are at room temperature before mixing. If the butter is too cold, the all-in-one method won’t work effectively, leading to dense patches in the crumb.
Don’t Overmix: Stop beating as soon as the batter is smooth. Overworking the flour can develop the gluten too much, resulting in a tough, rubbery loaf rather than a tender sponge.
The Right Sugar for Topping: Use granulated sugar for the drizzle, not caster or icing sugar. The larger crystals of granulated sugar are what create the signature crunchy white crust that contrasts with the soft sponge.
checking for Doneness: Loaf cakes take longer to bake than sandwich cakes. If the skewer is wet, give it another 5-10 minutes, but cover the top with foil to prevent burning.

What To Serve With Lemon Loaf Cake

This cake is a teatime staple and is best served simply with a cup of Earl Grey or English Breakfast tea. The citrus notes cut through the richness of the butter, making it refreshing on the palate. For a dessert option, serve a thick slice with a dollop of crème fraîche or Greek yoghurt and some fresh raspberries.

How To Store

Store the cooled cake in an airtight container at room temperature; it will stay moist for up to 4 days. In fact, the lemon flavour often improves on the second day. You can also freeze the loaf (without the drizzle is best, but with is fine) for up to 3 months—wrap it tightly in cling film and foil.

FAQs

Why did my loaf cake sink in the middle?
This usually happens if the oven door was opened too early or the cake was underbaked. Ensure you don’t open the oven before the 50-minute mark and check that the centre is fully cooked with a skewer.

Can I use plain flour instead of self-raising?
Yes, you can use plain flour, but you will need to add more baking powder. Use 225g plain flour and add 3 level teaspoons of baking powder (total) to get the right lift.

Why is my drizzle soggy not crunchy?
This happens if you use caster sugar instead of granulated, or if you pour the drizzle onto a cold cake. The cake needs to be hot to absorb the liquid quickly, leaving the sugar crystals on top.

Can I make this in a round tin?
Yes, this quantity fits a 20cm (8-inch) round deep cake tin. You will likely need to reduce the baking time to roughly 35-45 minutes.

My batter looks curdled, does it matter?
If you add cold eggs to the butter mixture, it may curdle. It usually corrects itself when you add the flour, but try to use room temperature ingredients to avoid this.
