The texture is soft and tender with a delicate crumb, while the sharp lemon topping cuts through the sweetness perfectly.

What Makes This Gluten-Free Lemon Drizzle Cake So Good?
Mary Berry’s approach to lemon drizzle cake is all about simplicity and flavour. This gluten-free version stays true to that philosophy, swapping regular flour for a quality gluten-free self-raising blend without sacrificing any of the lightness or taste you expect. The cake itself is wonderfully buttery and packed with fresh lemon zest, giving it a fragrant, citrusy aroma that fills the kitchen as it bakes.
The drizzle is where the magic happens. A mixture of fresh lemon juice and granulated sugar is poured over the warm cake so it soaks right into the sponge, creating a sticky, crunchy top layer with pockets of sweet-sour lemon running through the crumb. Every bite is moist, tangy, and perfectly balanced. This is the kind of cake that disappears fast at any gathering and tastes just as wonderful the next day.
Ingredients
For the Cake
- 225g unsalted butter, softened
- 225g caster sugar
- 4 large eggs
- 225g gluten-free self-raising flour
- 1 tsp gluten-free baking powder
- 1 tsp xanthan gum
- Finely grated zest of 2 large unwaxed lemons
- 2 tbsp milk
- Butter, for greasing the tin
- Baking parchment
For the Lemon Drizzle Topping
- Juice of 2 large lemons (approximately 80ml)
- 175g granulated sugar
How to Make Mary Berry Gluten-Free Lemon Drizzle Cake
- Prepare the oven and tin: Preheat the oven to 180°C or 160°C fan. Grease a 900g (2lb) loaf tin with butter and line the base and sides with baking parchment, leaving a little overhang to help you lift the cake out later.
- Combine the cake batter: Place the softened butter, caster sugar, eggs, gluten-free self-raising flour, baking powder, xanthan gum, lemon zest, and milk into a large mixing bowl. Beat with an electric hand mixer for about 2 minutes until the mixture is pale, smooth, and thoroughly combined. The batter should drop easily from a spoon. If it feels a little stiff, add another splash of milk.
- Fill the tin: Spoon the batter into the prepared loaf tin and level the top gently with the back of a spoon or a spatula. Create a very slight dip along the centre so the cake rises evenly without a large dome.
- Bake the cake: Place the tin on the middle shelf of the oven and bake for 45 to 50 minutes. The cake is ready when it is golden brown, well risen, and a skewer inserted into the centre comes out clean. If the top starts to brown too quickly, lay a piece of foil loosely over the tin for the final 10 minutes.
- Make the drizzle while the cake bakes: While the cake is in the oven, stir together the freshly squeezed lemon juice and granulated sugar in a small bowl. Do not try to dissolve the sugar fully as the slightly gritty texture is what gives the topping its signature crunch.
- Apply the drizzle: As soon as the cake comes out of the oven, poke holes all over the surface using a thin skewer or cocktail stick. Spoon the lemon sugar mixture evenly over the top of the hot cake, allowing it to seep down into the holes and soak through the sponge. Let it sit until the drizzle sets into a slightly crunchy glaze.
- Cool and serve: Leave the cake to cool completely in the tin. This allows the drizzle to set properly and makes the cake much easier to remove. Once cooled, lift the cake out using the parchment overhang, peel away the paper, and transfer to a serving plate. Slice and enjoy.

Tips for the Perfect Gluten-Free Lemon Drizzle Cake
Why is my gluten-free cake crumbly and dry?
Gluten-free flour absorbs more moisture than regular flour, so it is important not to overbake. Check your cake at the 45 minute mark and remove it as soon as a skewer comes out clean. Adding xanthan gum helps bind the crumb and gives structure, so do not skip this ingredient. Using room temperature eggs and softened butter also ensures everything emulsifies properly, keeping the sponge tender and moist.
Can I use any brand of gluten-free flour?
Not all gluten-free flours are the same. For best results, use a quality gluten-free self-raising flour blend that already contains a mix of rice flour, potato starch, and tapioca starch. Brands like Doves Farm or Bob’s Red Mill work particularly well for baking. Avoid using single grain flours like almond flour or coconut flour on their own as they behave very differently and will change the texture of your cake entirely.
How do I get the drizzle to stay crunchy on top?
The key is using granulated sugar rather than caster sugar for the drizzle. Granulated sugar has larger crystals that do not dissolve completely, which creates that lovely crunchy, slightly crystallised topping. Make sure you spoon the drizzle over the cake while it is still hot straight from the oven, and then leave it to cool completely in the tin without disturbing it.
Should I poke holes in the cake before drizzling?
Yes, absolutely. Poking holes all over the surface with a skewer allows the lemon syrup to travel deep into the sponge rather than just sitting on top. This is what gives every slice that gorgeous moist, lemony flavour all the way through. Use a thin skewer and make plenty of holes, spacing them about 1cm apart for even soaking.
What if I do not have xanthan gum?
Some gluten-free flour blends already include xanthan gum in their ingredients list. Check your packet before adding extra. If your flour blend already contains it, you can skip the additional teaspoon. If your flour does not include it and you cannot find xanthan gum, try adding 1 tablespoon of ground flaxseed mixed with 2 tablespoons of water as a binding alternative, though xanthan gum gives the best results.
Serving Suggestions
- Serve slices with a dollop of clotted cream or crème fraîche for afternoon tea
- Pair with a cup of Earl Grey or English breakfast tea for a classic combination
- Add a few fresh raspberries or blueberries on the side for a pop of colour and extra freshness
- Warm a slice gently and serve with vanilla ice cream for a simple dessert
- Dust with a light sprinkle of icing sugar and garnish with thin lemon slices for a beautiful presentation
Storage
Room Temperature
Store the lemon drizzle cake in an airtight container or wrapped tightly in cling film at room temperature for up to 3 days. The drizzle topping helps keep the sponge moist, so it actually tastes even better the day after baking once the lemon syrup has fully soaked in. Keep it away from direct sunlight and heat sources.
Refrigerator
If your kitchen is particularly warm or you want to extend the cake’s freshness, store it in the refrigerator in an airtight container for up to 5 days. Allow slices to come to room temperature for about 20 minutes before serving, as cold cake can taste slightly dense. The lemon flavour will intensify as it sits, which is a lovely bonus.
Freezing
This gluten-free lemon drizzle cake freezes beautifully. Wrap the cooled cake tightly in a double layer of cling film and then in a layer of foil. Freeze for up to 3 months. You can also slice the cake before freezing and wrap individual slices for easy portion control. Thaw overnight in the refrigerator or at room temperature for 2 to 3 hours before serving.

Frequently Asked Questions
Can I make this lemon drizzle cake with regular flour instead?
Yes, you can swap the gluten-free self-raising flour for standard self-raising flour and omit the xanthan gum. The method and quantities remain exactly the same, and the baking time will be unchanged. The result will be a classic Mary Berry lemon drizzle cake that works perfectly for anyone who does not need a gluten-free option.
Can I bake this in a round tin instead of a loaf tin?
Absolutely. Use a deep 20cm round cake tin, greased and lined. The baking time may reduce slightly to around 35 to 40 minutes, so start checking with a skewer at the 35 minute mark. The drizzle soaks in just as well on a round cake.
Why did my cake sink in the middle?
Sinking usually happens when the oven door is opened too early or when the cake is underbaked. Avoid opening the oven for at least the first 30 minutes. Also make sure your baking powder is fresh and within its use-by date, as expired leavening agents lose their effectiveness and cannot support the rise.
Is this cake suitable for people with coeliac disease?
Yes, provided you use certified gluten-free flour, gluten-free baking powder, and check that all other ingredients are confirmed gluten-free on their labels. Cross-contamination can occur with some brands, so always look for the certified gluten-free symbol if you are baking for someone with coeliac disease.
Can I add poppy seeds to this recipe?
Yes, lemon and poppy seed is a wonderful flavour combination. Fold in 2 tablespoons of poppy seeds at the end of mixing, just before transferring the batter to the tin. They add a lovely subtle crunch and visual appeal to each slice without affecting the baking time.
Can I use bottled lemon juice instead of fresh?
Fresh lemon juice is always recommended for the best flavour and the brightest, most natural citrus taste. Bottled lemon juice can taste slightly metallic or flat in comparison. Since the lemon is the star of this cake, using fresh lemons really does make a noticeable difference in the final result.
This Mary Berry gluten-free lemon drizzle cake is proof that going gluten-free does not mean giving up the bakes you love most. With its perfectly moist crumb, bold lemon flavour, and that irresistible crunchy sugar topping, this cake stands proudly alongside any traditional version. Whether you are baking for a friend with dietary needs, hosting afternoon tea, or simply craving something citrusy and comforting, this recipe delivers every single time.
