If you enjoy the combination of fresh lemon and juicy blueberries, this blueberry lemon loaf recipe is worth trying. It has a soft crumb, plenty of lemon flavour, bursts of blueberries in every slice, and a buttery crumble topping that adds a light crunch.
One thing I love about this recipe is that it doesn’t require an electric mixer. Everything comes together using simple mixing bowls, making it perfect whether you’re baking during the week or over the weekend.
If you’ve already tried my lemon cake or orange cake loaf recipes, you’ll notice one important step that I always use in citrus bakes—and for good reason.
Why This Blueberry Lemon Loaf Recipe Stand out
There are plenty of blueberry loaf recipes online, but here is why I keep coming back to this one:
- Fresh lemon zest and juice give the loaf a bright citrus flavour.
- Blueberries add little pockets of sweetness throughout the loaf.
- The crumble topping creates a buttery crunch that pairs well with the soft cake.
- The recipe uses both butter and oil for flavour and moisture.
- No electric mixer is needed.
- It stays soft for several days when stored properly.
- It works well for breakfast, tea time or dessert.
I have baked many lemon cakes over the years, and one thing I always come back to is how well fresh lemon works with blueberries. The sweetness of the berries balances the brightness of the lemon, making every bite enjoyable.

The Ingredients That Make This Loaf So Good
Instead of focusing on every ingredient, let’s look at the ones that really make this recipe stand out. For full ingredients, check the recipe card.
Blueberries
Fresh blueberries work well, but frozen blueberries can also be used. If using frozen berries, don’t thaw them first. Adding them straight from the freezer helps reduce bleeding into the batter.
Tossing the blueberries in a little flour before folding them into the batter can also help keep them evenly distributed.
Fresh Lemon Zest and Lemon Juice
Fresh lemons provide two important components. The zest gives concentrated lemon oils that provide deep citrus flavor.
The juice adds brightness and balances the sweetness of the loaf.
Using both zest and juice creates a fuller lemon flavor than using only one of them.
Buttermilk (or Maas)
Buttermilk adds moisture and creates a tender crumb. It also reacts with the baking soda, helping the loaf rise properly while keeping the texture light.
If you’re in South Africa, maas works perfectly in this recipe.
Butter and Oil Together
I rarely choose only butter or only oil for loaf cakes. Butter provides flavor while oil provides moisture.
Using both gives you a loaf that tastes rich while staying soft even the next day. That’s one reason I come back to this combination in many of my loaf recipes.
The Secret Step: Rubbing Lemon Zest Into the Sugar
Before mixing the wet ingredients, I always rub the lemon zest into the granulated sugar using my fingertips.
This is one of the most important steps in the recipe.
As you rub the zest into the sugar, the sugar helps release the natural oils from the lemon peel. Those oils carry much of the lemon flavor, giving the loaf a stronger citrus taste without adding extra lemon juice.
I use this exact technique in my lemon cake and my orange cake loaf because it makes a noticeable difference. It only takes about a minute, but the flavor payoff is worth it.
Don’t skip this step.
Don’t Skip the Crumble Topping
The crumble topping may seem optional, but I highly recommend making it. It adds texture that contrasts with the soft loaf underneath.
As it bakes, the topping becomes lightly crisp while the inside stays moist.
Let the Loaf Rest Before Slicing
One mistake many bakers make is cutting into the loaf as soon as it comes out of the oven.
I know it’s tempting because the kitchen smells amazing.
However, allowing the loaf to cool completely gives the crumb time to set.
If you slice it too early:
- the loaf can fall apart,
- steam escapes too quickly,
- the texture may seem gummy,
- slices won’t hold their shape.
Waiting produces cleaner slices and better texture.
Tips for the Best Blueberry Lemon Loaf
- Room temperature eggs, butter and buttermilk mix together more easily and create a smoother batter.
- Too much flour creates a dry loaf. For the best results, spoon the flour into the measuring cup and level it instead of scooping directly from the bag.
- Mix only until the flour disappears. Overmixing develops gluten and can make the loaf dense.
- Use a spatula instead of vigorous stirring to keep the berries intact.
- Insert a skewer into the center. It should come out with only a few moist crumbs attached.
- Allowing the loaf to cool completely improves both texture and flavor.
Storage Tips
Store the loaf in an airtight container at room temperature for up to three days.
For longer storage, refrigerate it for several days.
You can also freeze individual slices so you always have one ready when the craving hits.

Blueberry Loaf Recipe
Ingredients
Equipment
Method
- Preheat your oven to 180°C (356°F). Grease and line a standard 9×5-inch (23×13 cm) loaf pan with baking paper.
- Prepare the crumble topping by combining the melted butter, sugar, flour, and lemon zest in a small bowl. Mix until crumbly, then set aside.

- Add the softened butter and canola oil, then whisk until well combined.
- Whisk in the vanilla extract, eggs, lemon juice, buttermilk (or maas), and vinegar until smooth.
- Add the cake flour, baking powder, baking soda, and salt. Fold the dry ingredients into the wet ingredients until just combined. Do not overmix.
- Gently fold in the blueberries using a spatula.
- Pour the batter into the prepared loaf pan and spread it evenly.
- Sprinkle the crumble topping evenly over the batter.
- Bake for 55–65 minutes, or until a skewer inserted into the center comes out clean or with a few moist crumbs.
- Allow the loaf to cool in the pan for 10–15 minutes before transferring it to a wire rack to cool completely.
- Let the loaf rest completely before slicing for the best texture and clean slices.
