Lemon Blueberry Loaf

WANT TO SAVE THIS RECIPE?

There’s something magical about the combination of tangy lemon and juicy blueberries baked into a tender, golden loaf. I remember the first time I tried this Lemon Blueberry Loaf — it was still slightly warm from the oven, the edges crisp, and the inside bursting with vibrant berry flavor. I instantly fell in love with how bright and comforting it tasted, like summer mornings wrapped in a cozy hug.

This loaf has become my go-to when I want something sweet but not too sugary, something that feels like a treat without going over the top. It’s the kind of bake that fills the kitchen with the scent of citrus and vanilla, and it pairs beautifully with a cup of coffee, a glass of iced tea, or just a quiet afternoon moment. Whether you’re making it for breakfast, brunch, or dessert, this Lemon Blueberry Loaf will never let you down.

What Kind of Blueberries Should I Use?

You can use either fresh or frozen blueberries in this Lemon Blueberry Loaf — both work beautifully. I tend to go with fresh when they’re in season because they’re plump and sweet, but frozen ones are a solid choice year-round. If you do use frozen, don’t thaw them first; toss them straight into the batter. That helps keep them from bleeding too much color and turning the loaf purple. Give them a light dusting of flour before mixing them in to help distribute them evenly and prevent them from sinking.

Options for Substitutions

What I love about this recipe is how flexible it can be with a few smart swaps:

• Greek Yogurt or Sour Cream: Both work perfectly to give the loaf moisture and richness. You can even use plain regular yogurt in a pinch.
• Lemon Juice and Zest: Fresh is always best, but bottled lemon juice can work if needed. Just make sure to still include fresh zest — it’s where the punchy citrus flavor lives.
• Butter or Oil: If you don’t have butter, a neutral oil like canola or vegetable oil can work. It will give a slightly different texture but still delicious.
• Gluten-Free Flour: Use a good 1:1 gluten-free baking blend if you’re avoiding gluten. It might be a little more delicate, but it still turns out lovely.
• Sweetener: Want it slightly healthier? Try swapping some of the sugar with honey or maple syrup, though you may need to adjust the flour a bit to balance moisture.

Ingredients for This Lemon Blueberry Loaf

• All-Purpose Flour
  This is the base of the loaf, providing structure and a tender crumb. It holds everything together without being too heavy.
• Baking Powder
  Essential for giving the loaf that light, fluffy rise. It helps balance out the density from the yogurt and blueberries.
• Salt
  Just a pinch sharpens the sweetness and enhances the flavors, especially the lemon.
• Unsalted Butter
  Adds richness and a soft, moist texture to the loaf. Using unsalted gives better control over the overall salt level.
• Granulated Sugar
  Sweetens the loaf and also helps create a golden, slightly crisp top when baked.
• Eggs
  They act as a binder and add structure and moisture. They’re key to a well-risen, rich loaf.
• Lemon Zest and Juice
  These bring the bright, tangy citrus flavor that makes this loaf so refreshing and vibrant.
• Plain Greek Yogurt or Sour Cream
  Adds moisture and a slight tang that pairs beautifully with the lemon. Keeps the loaf tender for days.
• Vanilla Extract
  Enhances the sweetness and brings a cozy depth that balances out the citrus.
• Blueberries (Fresh or Frozen)
  The star ingredient — they add bursts of sweet juiciness in every bite and pair perfectly with lemon.
• All-Purpose Flour (extra, for coating blueberries)
  A light coating helps keep the blueberries suspended in the batter so they don’t all sink to the bottom.

Step 1: Prep the Oven and Pan

Preheat your oven to 350°F (175°C). Lightly grease a 9×5-inch loaf pan or line it with parchment paper for easy removal. This ensures your loaf doesn’t stick and comes out clean every time.

---

Step 2: Mix the Dry Ingredients

In a medium bowl, whisk together the flour, baking powder, and salt. Set this aside — mixing them separately keeps everything evenly distributed and avoids overmixing later.

---

Step 3: Cream the Butter and Sugar

In a large bowl, beat the softened butter and granulated sugar together until the mixture is light and fluffy. This step is key for that perfect, tender crumb texture.

---

Step 4: Add the Eggs, Lemon, and Vanilla

Beat in the eggs one at a time, then stir in the lemon zest, lemon juice, and vanilla extract. The mixture may look a little curdled — that’s totally fine at this stage.

---

Step 5: Mix in the Yogurt

Add the Greek yogurt (or sour cream) and mix until fully incorporated. It should look smooth and creamy.

---

Step 6: Combine Wet and Dry Ingredients

Gradually add the dry flour mixture to the wet ingredients. Stir just until everything is combined — don’t overmix or the loaf could turn out dense.

---

Step 7: Fold in the Blueberries

Toss your blueberries in a little flour, then gently fold them into the batter. This keeps them from sinking and helps distribute them throughout the loaf.

---

Step 8: Bake the Loaf

Pour the batter into your prepared loaf pan, smoothing the top. Bake for 50–60 minutes or until a toothpick inserted into the center comes out clean or with just a few moist crumbs.

---

Step 9: Cool and Serve

Let the loaf cool in the pan for 10–15 minutes, then transfer it to a wire rack to cool completely. Once cooled, slice and enjoy — or drizzle with a simple lemon glaze if you’re feeling fancy.

How Long to Cook the Lemon Blueberry Loaf

The Lemon Blueberry Loaf typically takes about 50 to 60 minutes in a 350°F (175°C) oven. You’ll know it’s ready when the top is golden brown and a toothpick inserted into the center comes out clean or with just a few moist crumbs. Be careful not to overbake — that’s the quickest way to dry out your beautiful loaf. If the top starts browning too quickly, loosely tent it with foil for the last 10–15 minutes.

Tips for Perfect Lemon Blueberry Loaf

• Don’t Overmix the Batter: Once the flour goes in, mix gently. Overmixing leads to a tough, dense loaf.
• Room Temperature Ingredients: Butter, eggs, and yogurt blend better when they’re not straight from the fridge.
• Flour the Blueberries: This keeps them from all sinking to the bottom and helps them stay suspended throughout the loaf.
• Use Fresh Lemon Zest: It adds way more flavor than bottled juice alone — that citrus oil makes a big difference.
• Check Early: Oven temps vary, so check for doneness at the 50-minute mark with a toothpick.
• Let It Cool Before Slicing: It’s tempting to dig in, but cooling allows the loaf to set and slice cleanly.
• Want Extra Lemon Kick? Add a quick lemon glaze (just lemon juice + powdered sugar) once the loaf cools.
• Use a Light-Colored Loaf Pan: Dark pans can brown the outside too quickly before the inside cooks through.

Watch Out for These Mistakes While Cooking

Even a simple recipe like this Lemon Blueberry Loaf can go sideways with a few small missteps. Here’s what to keep an eye out for:

• Skipping the Flour Dusting on Blueberries: Without that little step, your blueberries will likely sink straight to the bottom of the loaf.
• Overmixing the Batter: It’s tempting to stir until silky smooth, but too much mixing develops the gluten and makes the loaf dense.
• Not Measuring Flour Properly: Scooping directly from the bag can pack in too much flour. Spoon and level it for best results.
• Using Cold Ingredients: Cold eggs or butter can cause the batter to curdle and mix unevenly.
• Underbaking or Overbaking: Always test the center with a toothpick and rotate your pan if your oven bakes unevenly.
• Using Bottled Lemon Juice Only: You’ll lose the bright, fresh flavor that only zest and freshly squeezed juice can bring.
• Ignoring Pan Size: A smaller loaf pan will cause overflow, and a larger one may make the loaf too flat. Stick to a standard 9×5-inch pan.
• Not Letting It Cool: Cutting too early can cause the loaf to crumble and lose its texture.

Frequently Asked Questions

Can I use frozen blueberries instead of fresh ones?

Yes, frozen blueberries work just as well! Don’t thaw them — toss them into the batter straight from the freezer and coat them lightly in flour first to prevent them from sinking.

What if I don’t have Greek yogurt?

You can substitute with sour cream or even regular plain yogurt. Just make sure it’s not flavored or overly watery.

Can I make this loaf gluten-free?

Absolutely. Use a 1:1 gluten-free baking flour blend. The texture may be slightly more delicate, but it still turns out wonderfully.

Can I turn this into muffins instead?

Definitely! Pour the batter into muffin tins and bake at 350°F for 18–22 minutes. Keep an eye on them and test with a toothpick for doneness.

Is this loaf overly sweet?

Nope — it’s just right. The sweetness is balanced by the lemon’s tartness. But if you want it even less sweet, you can reduce the sugar slightly.

How do I keep the loaf moist?

The Greek yogurt (or sour cream) is the key to a moist loaf. Just be careful not to overbake it — that’s the quickest way to dry it out.

What kind of lemons should I use?

Fresh, standard lemons are perfect. If you can find Meyer lemons, they’ll give the loaf a slightly sweeter and more floral twist.

Can I add a glaze on top?

Yes, and it’s delicious. Mix powdered sugar with a bit of lemon juice and drizzle it over the cooled loaf for a zesty, glossy finish.
