Blueberry Cake Lemon Frosting
There is something utterly delightful about the combination of plump, juicy blueberries and sharp, zesty lemon. It’s a pairing that sings of sunny afternoons and kitchen tables laden with treats. This blueberry cake with lemon frosting is the culmination of that perfect partnership. The cake itself is wonderfully soft and moist, studded with bursts of sweet fruit, while the lemon cream cheese frosting provides a tangy, creamy finish that cuts through the sweetness beautifully. Friends always ask me for this recipe after trying it at dinner parties, and it’s become one of my most requested bakes.
What I adore about this particular recipe is how the textures and flavours work in harmony. The cake crumb is tender, thanks to the buttermilk, and it holds the blueberries perfectly so they don’t all sink to the bottom. We then top it with a generous layer of frosting that is both rich from the cream cheese and bright from the fresh lemon zest and juice. It’s the sort of dessert that feels special enough for an occasion but is straightforward enough to bake on a quiet weekend.
It’s a wonderful cake to serve for an afternoon tea, a family get-together, or simply as a well-deserved treat with a cup of tea. The vibrant flavours make it a welcome addition to any dessert table, and everyone seems to love the classic combination. Whether you’re an experienced baker or just starting out, this recipe will guide you to a truly memorable fruit cake.
Recipe Overview
This recipe yields a beautifully tender, single-layer blueberry cake crowned with a zesty and smooth lemon cream cheese frosting. The flavour profile is a balance of sweet and tangy, with a soft, moist crumb that melts in your mouth. From my experience, the key is not to overmix the batter once the flour is added; this ensures the cake remains light and airy.

Why You’ll Love This Blueberry Cake Lemon Frosting
- Genuine Flavour: The taste is authentic and vibrant. You get the distinct sweetness from the blueberries, which burst gently as you bake them, creating little pockets of jamminess, all balanced by the sharp, fragrant zest in the lemon frosting.
- Comes Together in Under an Hour: The active preparation and baking time is just over an hour, making it an achievable bake for a weekend afternoon. The majority of the time is hands-off while it bakes and cools.
- Flexible Recipe: You can easily use fresh or frozen blueberries (no need to thaw!). If lemons aren’t to hand, lime or orange zest works wonderfully in the frosting for a different citrus note.
- Works Beautifully for Gatherings: This is a brilliant cake for a spring lunch, a summer garden party, or even a birthday celebration. Its bright appearance and fresh taste are always a welcome sight.
- Family Tested: My children adore this cake. They love spotting the “purple jewels” inside, and it’s one of the few recipes where there are never any leftovers in our house!
Ingredients You’ll Need
For the best results, I recommend using full-fat ingredients for the cake and frosting, especially the cream cheese and buttermilk. It makes a significant difference to the final texture. I always use Philadelphia full-fat cream cheese as I find it gives the frosting the perfect stable, creamy consistency.
- For the Blueberry Cake:
- 225g unsalted butter, softened
- 225g caster sugar
- 4 medium free-range eggs, at room temperature
- 1 tsp vanilla extract
- 275g plain flour, plus 1 tbsp extra for the blueberries
- 2 tsp baking powder
- ½ tsp salt
- 120ml buttermilk, at room temperature
- 200g fresh or frozen blueberries
- For the Lemon Cream Cheese Frosting:
- 150g unsalted butter, softened
- 225g full-fat cream cheese, cold from the fridge
- 450g icing sugar, sifted
- 1 tsp vanilla extract
- Zest of 2 large lemons
- 2-3 tbsp fresh lemon juice
Elena’s Tip: Ensure your butter, eggs, and buttermilk are all at room temperature before you begin. This helps them emulsify properly, leading to a much smoother batter and a more even, tender crumb in your finished cake.
How to Make Blueberry Cake Lemon Frosting
The process for this cake is quite methodical. We start by creating a light, aerated batter, gently fold in the fruit, and then whip up the tangy frosting while the cake cools completely. Following these steps will give you a perfect result every time.
- Preheat and Prepare: Preheat your oven to 180°C (160°C fan) and grease and line a 23cm (9-inch) round cake tin with baking parchment.
- Cream Butter and Sugar: In a large bowl using a stand mixer or electric hand mixer, beat the softened butter and caster sugar together for about 5-7 minutes. The mixture should become very light, pale, and fluffy. This step is crucial for a light cake, so don’t rush it. This technique, known as creaming, incorporates air into the batter.
- Add Eggs and Vanilla: Add the eggs one at a time, beating well after each addition to ensure they are fully incorporated. If the mixture looks like it might curdle, add a tablespoon of your flour. Stir in the vanilla extract.
- Combine Dry Ingredients: In a separate bowl, whisk together the 275g of plain flour, baking powder, and salt.
- Alternate Wet and Dry: Add one-third of the flour mixture to the wet ingredients and mix on low speed until just combined. Pour in half of the buttermilk and mix again. Repeat this process, ending with the final third of the flour mixture. Mix only until you no longer see streaks of flour.
- Fold in Blueberries: In a small bowl, gently toss the blueberries with the extra 1 tablespoon of flour. This helps prevent them from sinking to the bottom of the cake. Carefully fold the coated blueberries into the batter using a spatula. What works best for me is a gentle figure-of-eight motion.
- Bake the Cake: Pour the batter into your prepared tin and smooth the top. Bake for 35-40 minutes, or until a skewer inserted into the centre comes out clean.
- Cool Completely: Let the cake cool in the tin for 15 minutes before turning it out onto a wire rack to cool completely. It must be 100% cool before you attempt to frost it, otherwise the frosting will melt.
- Make the Frosting: While the cake cools, make the lemon frosting. In a large bowl, beat the softened butter until smooth. Add the cold cream cheese and beat for another minute until just combined. Don’t overbeat. Gradually add the sifted icing sugar, mixing on low speed until it’s incorporated, then increase the speed and beat until smooth. Finally, beat in the vanilla, lemon zest, and 2 tablespoons of lemon juice. Add the last tablespoon of juice if you want a stronger lemon flavour or thinner consistency.
- Assemble the Cake: Once the cake is completely cool, place it on a serving plate or cake stand. Spread the lemon cream cheese frosting evenly over the top, creating rustic swirls with the back of a spoon or a palette knife. You can garnish with a little extra lemon zest or a few fresh blueberries if you like.
Tips From My Kitchen
- Temperature is Key: For the frosting, it’s vital that your butter is soft but your cream cheese is cold, straight from the fridge. This contrast helps create a stable frosting that holds its shape without becoming runny.
- The Flour-Coating Trick: I learned that tossing the blueberries in a little flour is the single most effective way to keep them suspended in the batter. It gives them something to grip onto, preventing a soggy-bottomed cake.
- Make-Ahead Method: You can bake the cake layer a day in advance. Once completely cool, wrap it tightly in cling film and store it at room temperature. The frosting can also be made ahead and stored in an airtight container in the fridge for up to 3 days. Just let it sit at room temperature for 20-30 minutes and give it a quick whip before using.
- Storage: Because of the cream cheese frosting, this cake must be stored in the fridge. Keep it in an airtight container where it will last for up to 4 days. I find it tastes best if you let it sit out for 20 minutes before serving to take the chill off.
Equipment You’ll Need
- Stand mixer or electric hand mixer
- 23cm (9-inch) round cake tin
- Baking parchment
- Wire cooling rack
- Spatula and mixing bowls
- Zester or fine grater
Delicious Variations to Try
While this blueberry and lemon combination is a classic, the recipe is a wonderful base for experimentation. Here are a few ideas I’ve tried over the years:
- Alternative Berries: This cake works beautifully with other berries. Try substituting the blueberries with fresh raspberries (and perhaps a little lime zest in the frosting) or chopped strawberries.
- Gluten-Free Version: For a gluten-free cake, replace the plain flour with a good quality gluten-free all-purpose flour blend that contains xanthan gum. The texture will be slightly different, but still delicious.
- A Hint of Spice: Add half a teaspoon of ground cardamom or nutmeg to the dry ingredients for a subtle, warming spice note that complements the blueberries wonderfully.
What to Serve With Blueberry Cake Lemon Frosting
This cake is a complete dessert on its own, but a few simple accompaniments can elevate it further. It’s a lovely way to finish a meal, especially after a lighter main course like our Classic Shrimp Scampi Recipe In Minutes.
- A Dollop of Cream: Serve a slice with a spoonful of thick clotted cream or a simple dollop of crème fraîche to balance the sweetness.
- Fresh Fruit: A small handful of extra fresh blueberries or raspberries on the side adds a fresh, juicy contrast.
- A Cup of Tea: A pot of Earl Grey or English Breakfast tea is the quintessential pairing. The tannins in the tea cut through the richness of the frosting perfectly.
