This lemon blueberry loaf is bursting with fresh flavor. The lemon loaf batter is so incredibly moist and tender and whips up in a flash. It's dotted with deliciously juicy blueberries and topped with a sweet lemon icing for a loaf that rivals a bakery!

lemon blueberry quick bread
A lot of the beauty in a quick bread is the fact that it's ... well, quick! The only time consuming part is waiting for it to bake and cool - but the actual work involved in making this bread is very minimal.
This loaf is whipped up a lot like a muffin batter: whisk together wet and dry ingredients separately - then combine. It uses all oil for the batter, which not only saves time (because there's no need to bring any ingredients up to room temperature), but it also creates an unbelievably moist and spongy loaf that keeps for days!
Since we're using all oil, I also decided to use a mix of milk and sour cream in the batter to bring back some richness that we lost since we’re not including butter. The sour cream also helps make the loaf a little extra tangy and extra tender.
This recipe originally used cake flour, but I've switched it to a mix of all-purpose flour and cornstarch just because they're more common household ingredients. By doing this, we're essentially making our own homemade blend of cake flour. The cornstarch creates a softer loaf thanks to its lighter texture and high absorption!

how to make lemon blueberry loaf
I wanted this loaf to be as easy to make as possible - and that involved avoiding the need for bringing any ingredients up to room temperature. I also wanted it to be a drop everything into a bowl and mix kind of recipe. So to achieve both of those goals, we're using an oil based batter.
To start the batter, the dry ingredients are all whisked together in a bowl then set aside. Next, use your fingers to rub together sugar and lemon zest in a separate bowl.
This is an additional step - and it's technically optional but highly recommended! The friction from the sugar bruising the zest will help release more of its natural citrus oil and will intensify the lemon flavor! Once that's done, all the remaining wet ingredients are whisked into the lemon/sugar mixture to combine.


Now it's time to take a little pause before combining the wet and dry ingredients to prep the blueberries. In a separate bowl, toss the blueberries in flour so they're fully coated.
Back to the batter: now the dry ingredients and wet ingredients are combined and mixed together. The batter should almost be combined but should still have a few streaks of dry ingredients - we'll work those out in a second.
Finally, add in the floured blueberries and fold together until you no longer see any dry pockets. The batter will be a little lumpy.
Once the batter is ready, it's time to pour it into your loaf pan and bake.




blueberries
This may seem insignificant, but when you toss the blueberries in flour can actually make a difference. This recipe calls for whisking the wet and dry ingredients for the batter separately and then moving over to work on the blueberries before finishing up the batter.
The blueberries shouldn't be tossed in flour too early on because the flour can become goopy as it sits. We’re just looking for a dry, snowy coverage on the blueberries.

You also shouldn't fully complete the batter and then work on the blueberries because the baking powder will start working and forming bubbles once the wet and dry ingredients are combined. Baking powder is double acting, meaning it gets to work creating bubbles twice: first when it hits the wet ingredients and again when it's heated.
If you finish the batter and then start working on the blueberries, the baking powder will start working creating bubbles in the batter. When you try to then fold in the blueberries, you'll deflate those bubbles and reduce the effectiveness of the baking powder's first reaction.
tips for making lemon blueberry loaf
1. Measure flour accurately: One of the keys to a moist and tender loaf is measuring the flour accurately. The best way to measure is to use a food scale if you have one handy. But if you do prefer to use cups, don't scoop the measuring cup directly into your bag of flour. This can pack in the flour and you could end up with more weight in the batter as a result. Instead, use a spoon to scoop flour into your cup and then level off any excess with a flat utensil.
2. Fresh lemon, fresh blueberries: When it comes to the lemon juice, avoid those prepackaged bottles of juice. They just don't compare in terms of acidity and flavor. For the blueberries, I also recommend using fresh over frozen. Frozen blueberries can bleed into the batter and will also require a longer bake time, which can impact the rise of your loaf.
3. Tossing blueberries in flour: Before folding the blueberries into the batter, we first toss them in some flour to coat. If you try to throw in plain blueberries, they'll sink to the bottom of the loaf. Coating them in flour beforehand helps suspend them in the batter and gives you a more even distribution in the loaf.
4. Lumpy batter: Just like with pancakes, small clumps in the batter will create a a more tender loaf! Don't try to keep whisking the batter until it's fully smooth or you'll overwork it. When mixing, all you're looking for is a batter that's evenly combined and free of any dry streaks.
5. Baking to perfection: If you notice the loaf is browning too quickly before the center has a chance to cook through, loosely tent the loaf with aluminum foil. The foil will slow the browning on the surface and will allow the loaf to continue baking through.

storage instructions
Avoid slicing the loaf until right before you want to serve it to preserve maximum freshness (the less air the center is exposed to, the longer it'll stay moist). Store the loaf in an airtight container or plastic bag and it'll keep for up to 5 days at room temperature or around a week in the fridge.

Lemon Blueberry Loaf Cake
- Total Time: 2 hours 30 minutes
- Yield: 1 loaf
Description
This lemon blueberry loaf is bursting with fresh flavor. The lemon loaf batter is so incredibly moist and tender and whips up in a flash. It's dotted with deliciously juicy blueberries and topped with a sweet lemon icing for a loaf that rivals a bakery!
Ingredients
Lemon blueberry loaf:
- 1 ¾ cups (225g) all-purpose flour, spooned and leveled
- 2 tablespoons cornstarch
- 2 teaspoons baking powder
- ¼ teaspoon salt
- 1 cup (200g) granulated sugar
- 2 tablespoons lemon zest (about 2 lemons)
- ⅓ cup (80mL) whole milk
- ½ cup (120g) full-fat sour cream
- ½ cup (120mL) vegetable oil
- 2 large eggs
- 2 tablespoons fresh lemon juice (about 1 lemon)
- 1 teaspoon pure vanilla extract
Blueberries:
- 1 ½ cups (225g) fresh blueberries, washed and drained
- 1 ½ tablespoons all-purpose flour
Lemon icing:
- 1 cup (130g) powdered sugar
- 1-2 tablespoons fresh lemon juice
Instructions
Make the lemon blueberry loaf:
- Preheat your oven to 350F. Grease an 8.5x4.5" loaf pan and line with parchment paper. Leave a bit of extra parchment paper hanging over the sides of the pan to make it easier to pull the loaf out later. Set aside.
- In a medium bowl, whisk together flour, cornstarch, baking powder, and salt. Set aside.
- In a large bowl, combine sugar and lemon zest. Use your fingers to rub them together - this helps release the natural oil in the zest and add more flavor to the loaf.
- Pour in milk, sour cream, oil, eggs, lemon juice, and vanilla. Whisk to combine.
- Now take a second to prep the blueberries. In a medium bowl, toss together blueberries and 1 ½ tablespoons of flour to coat.
- Back to the batter, add the dry ingredients to the wet ingredients and mix together stopping right before the flour is fully absorbed.
- Add in the blueberries and fold everything together until you no longer see dry streaks of flour. Careful not to overmix.
- Pour your batter into the prepared loaf pan and spread into an even layer.
- Bake the loaf in the center of your preheated oven for 1 hour 5 minutes or until a skewer inserted into the center comes out clean with a few moist crumbs. If the loaf is browning too quickly, loosely tent the top with aluminum foil to finish baking through.
- Cool the loaf for about 45 minutes in the pan then use the parchment paper overhang to lift the loaf out and onto a wire rack. Set aside to prep the icing.
Make the icing:
- In a medium sized bowl, whisk together powdered sugar and 1 tablespoon of lemon juice.
- If the icing is too thick, thin it out with a bit more lemon juice. If it's too thin, add more powdered sugar until it reaches your desired consistency.
- Drizzle the icing over the loaf. You can slice it right away (but it will be a bit messy while the icing is still fresh) or wait for the icing to set for cleaner slices.
