⭐ Why you’ll love it

🛒 Ingredients (serves 8–10)
For the cake:
- 200g plain flour
- 2 tsp baking powder
- 1/2 tsp bicarbonate of soda
- 1/4 tsp salt
- 150g caster sugar
- 100g unsalted butter, softened
- 2 large eggs
- 150g sour cream or Greek yoghurt
- Zest of 2 lemons
- 2 tbsp fresh lemon juice
- 1 tsp vanilla extract
- 150g blueberries (fresh or frozen, unthawed)
For the streusel topping:
- 80g plain flour
- 60g light brown sugar
- 50g cold butter, cubed
- 1/2 tsp cinnamon
For the lemon glaze:
- 100g icing sugar
- 2–3 tbsp lemon juice

👩🍳 Method
Preheat your oven to 180°C (160°C fan). Grease and line a 20cm cake tin.
Start with the streusel. Rub the cold butter into the flour, sugar, and cinnamon until you get a coarse, crumbly texture. Pop it in the fridge while you prepare the batter—this helps it stay crisp.
In a bowl, whisk together the flour, baking powder, bicarbonate of soda, and salt.
In a separate bowl, cream the butter and sugar until light and fluffy. Beat in the eggs one at a time, then mix in the sour cream, lemon zest, lemon juice, and vanilla.
Fold the dry ingredients into the wet mixture gently—don’t overmix.
Toss the blueberries lightly in flour, then fold them into the batter.
Pour the batter into the tin and smooth the top. Sprinkle the chilled streusel evenly over the surface.
Bake for 40–50 minutes, until golden and a skewer inserted into the centre comes out clean.
Allow the cake to cool slightly before removing from the tin.
🍋 Finishing touch
Mix the icing sugar with lemon juice to create a smooth glaze. Drizzle over the cake once it’s cooled slightly for that classic finish.
🍽️ Serving ideas
Serve your blueberry lemon coffee cake slightly warm with:
- A cup of coffee or tea
- A spoonful of crème fraîche or yoghurt
- Extra berries on the side
🔍 Tips for success
Use fresh lemon zest for the best flavour—bottled just won’t compare.
Keep the streusel cold before baking for a better crumb texture.
Avoid overbaking to maintain a moist, tender cake.
🔄 Variations
- Almond crumble: Add flaked almonds to the topping
- Extra citrus hit: Include orange zest alongside lemon
- Loaf version: Bake in a loaf tin and extend baking time slightly
🧊 Storage
Store in an airtight container for up to 3 days. It also freezes well—just skip the glaze until serving.
This moist lemon blueberry coffee cake is bright, buttery, and wonderfully textured—the kind of bake that works just as well for a relaxed brunch as it does for a proper catch-up over coffee.
