Mary Berry Lemon And Poppy Seed Loaf Cake Ingredients
- 1 cup salted butter, cut into chunks
- 1 cup superfine sugar
- 2 1/2 cups self-rising flour
- 1 teaspoon baking powder

How to Make Mary Berry’s Lemon and Poppy Seed Loaf Cake
- Butter a 13×9-inch tin. Line it with parchment.
Oven on: 350°F (175°C). - Throw the butter, sugar, flour, baking powder, eggs, milk, and lemon zest into a bowl.
Beat it — low at first, then medium — until fluffy and smooth.
Chuck in the poppy seeds, quick stir. - Scrape it into the tin. Level it off.
- Bake 25–30 minutes.
Touch the middle — if it springs back, it’s done. - While it bakes, mix your glaze — lemon juice + sugar.
- Cake out of the oven. Straight away, pour the glaze all over.
Let it soak in while the cake cools. - Lift out with the parchment, slice thickly, and crack on.

Common Mistakes to Dodge
- Overmixing: Makes it tough. Stop when smooth.
- Cold butter: Won’t mix properly. Let it soften.
- Too hot glaze: Let the cake be hot — glaze coldish.
What to Serve It With
- Big mug of Earl Grey tea
- Dollop of whipped cream
- Fresh raspberries on the side
- Nothing. It’s perfect plain too.
Storage and Leftovers
- Fridge: Airtight tin, lasts 5 days.
- Freezer: Wrap slices tight, freeze for 3 months.
- Reheat: Short oven blast (325°F, 5–8 mins) or 20 secs in microwave.
