Notes on ingredients

You will need the following ingredients for this moist lemon poppy seed loaf:

• Butter — softened (or use melted and cooled butter).
• Granulated sugar — use plain white sugar so the lemon flavour stays pure.
• Lemon zest and juice — preferably unwaxed, organic lemons.
• Eggs — medium, at room temperature.
• Vanilla and salt — pure vanilla extract (or vanilla sugar) and a pinch of fine salt.
• Crème fraîche — or buttermilk or plain yogurt as alternatives.
• All-purpose flour (T45 if available).
• Baking powder — or baking soda with care about quantities.
• Poppy seeds — add a crunchy, slightly nutty texture; if you dislike the crunch, soak them briefly in water to soften.

How to make the Lemon and Poppy Seed Loaf

Quick visual steps. Full quantities and the printable recipe are in the recipe card below.

Step 1: In a large bowl, cream the softened butter, sugar and lemon zest with an electric mixer for about 3 minutes until smooth and fluffy.

Step 2: Add the vanilla, then beat in the eggs in two or three additions, mixing well after each addition until fully incorporated.

Step 3: Stir in the crème fraîche (or yogurt) and the lemon juice until combined.

Step 4: Fold in the dry ingredients — flour, baking powder, salt — and the poppy seeds using a flexible spatula until the batter is even and smooth.

Step 5: Preheat the oven to 180°C. Line a 25 cm loaf pan with parchment paper (or grease it), pour in the batter and smooth the top with the back of a spoon to distribute evenly.

Step 6: Bake for about 50–55 minutes until golden. Test with a skewer — it should come out clean. Let the cake cool completely in the pan before removing.

Tips for best results

• Use fresh lemons: Fresh juice and zest give the most vibrant flavour; organic lemons are ideal when using the zest.
• Zest carefully: Use a fine grater and avoid the bitter white pith.
• Squeeze juice last minute: Juice the lemons just before mixing for maximum brightness.
• Room-temperature eggs: They blend into the batter more easily and help structure the cake.
• Don’t overmix: Combine ingredients until just smooth — overmixing can make the loaf dense.
• Check doneness: Insert a skewer into the centre; if it comes out clean, the cake is ready.
• Cool before unmolding: Let the cake rest a few minutes in the pan to prevent breaking when removed.

Storage

Room temperature: Store at room temperature for up to 5 days in an airtight container to keep it soft and moist.

Freezer: For longer storage, slice the cooled cake, place pieces in airtight bags or containers and freeze for up to 3 months.

Variations and substitutions

• Plain lemon loaf: Omit poppy seeds if you prefer a smooth texture.
• Lemon and almonds: Add sliced or chopped almonds for extra crunch and a nutty note.
• Lemon-blueberry: Fold in fresh or frozen blueberries for a fruity twist.
• Cupcakes: Bake the batter as cupcakes and add poppy seeds for individual portions.
• Bundt version: Bake in a bundt pan for a more decorative presentation.
• Streusel topping: Add a crunchy crumble on top before baking for added texture.
