My inspiration for this lemon blueberry loaf was to make something a bit lighter to serve after a big Thai meal.

I froze a few leftover slices after we devoured most of the loaf. Mostly to keep my husband from polishing them off. A few days later, I was looking for something to satisfy my after-dinner sweet tooth craving and pulled out the frozen slices.  Too impatient to wait until they defrosted, I microwaved them for 20 seconds and inadvertently discovered that lemon-blueberry loaf warmed-up is sublime!

The recipe below is a version of 3 recipes by Ina Garten, Jo Cooks and Nagi from TinEats with a couple of minor tweaks.

What to expect

No stand mixer or hand mixer is needed – just mix with a whisk – my kind of recipe!

The end result is a simple, delicious super moist loaf that is easy to make and full of blueberry and lemon flavor. Not super low cal, but not bad as desserts go. So grab a cup of coffee and get baking ๐Ÿ™‚

Ingredients – tailored to your taste

blueberries, baking powder, sour cream, salt, sugar, flour, icing sugar, vanilla, lemons, eggs, butter.

Cake ingredients – We start with typical cake ingredients – flour, sugar, baking powder, eggs, oil and vanilla. We add sour cream for extra moistness, lemon zest and fresh blueberries.

Lemon syrup – this is optional for extra moisture and deeper lemon flavor. It’s just lemon juice mixed with a touch of sugar.

Glaze: A glaze of icing sugar, lemon juice and vanilla adds a nice finish, but is also optional.

  • To make the loaf lighter (less calories):
    • Leave out the lemon syrup. Or alternatively, use the syrup and leave out the glaze.
    • Substitute Greek yogurt or plain lower-fat yogurt for the sour cream.
    • Replace half the oil with applesauce (but note the texture of the loaf will be denser).
    • Just eat half a slice ๐Ÿ™‚
  • Blueberries: Try blackberries or raspberries instead of blueberries. Or leave out the blueberries – but you will then have to call it lemon loaf ๐Ÿ™‚
  • Garnish the loaf with lemon zest if you like.

  1. To measure flour, scoop it into a measuring cup, then level if off with a knife. Don’t just dip the scoop into the flour as this packs it in too much.
  2. Don’t overmix the batter to avoid a dense loaf.
  3. Toss the blueberries in flour before adding them to the batter. This will prevent them for all sinking to the bottom.
  4. Loaf pans and doneness: Glass loaf pan don’t conduct heat as well so the loaf will take longer to bake than in a metal pan. Regardless of the pan type, insert a toothpick or cake tester in the loaf to check if it is done. If it comes out clean or with a few crumbs, your loaf is ready.
  5. If the glaze is too thick, add a bit more lemon juice or water. If it’s too thin, add a bit more icing sugar.
  6. The loaf is delicious warmed in the microwave for a few seconds.

Make Ahead

  • Store leftovers a sealed container or ziploc bag at room temperature or in the fridge.
  • The loaf also freezes well, well wrapped, for up to 3 months in the freezer. 

Troubleshooting FAQs

Why did my loaf sink in the middle?

The loaf sinking in the middle may happen if the loaf is underbaked. Ensure you bake it until a toothpick inserted in the center comes out clean, and avoid opening the oven door.

Why is my loaf too dense?

Overmixing the batter can cause a dense loaf. Mix just until the ingredients are combined to avoid developing too much gluten.

Why is my loaf not rising properly

Ensure your baking powder is fresh. Also, properly whisk the oil and sugar to incorporate enough air into the batter.

Can I use frozen blueberries?

Yes, you can use frozen blueberries. Do not thaw them. Toss frozen blueberries in flour to prevent them from bleeding too much into the batter.

Why does the top of the lemon loaf crack?

The outside of the loaf cooks at a faster rate than the inside, so the inside of the cake continues to cook and rise, cracking the top crust.ย You can try lowering the temperature of the oven next time (especially if using a glass loaf pan), but the cracking is not a big deal with this loaf.

Lemon Blueberry Loaf (Super Moist With Big Flavor)

Moist, lemony and bursting with juicy blueberries, this lemon blueberry loaf is perfect for a tea, shower or brunch.
Prep Time15 minutes
Cook Time1 hour
Total Time1 hour 15 minutes
Course: Dessert
Cuisine: American
Servings: 12 slices

Ingredients

For Loaf

  • 1 1/2 cups all-purpose flour, Note 1
  • 2 teaspoon baking powder
  • 1/2 teaspoon salt
  • 1 cup sour cream or plain or Greek yoghurt
  • 1 cup sugar
  • 3 large eggs
  • 1 tablespoon lemon zest (from 1 large lemon)
  • 1/2 teaspoon vanilla extract
  • 1/2 cup vegetable or canola oil
  • 1 1/2 cups fresh blueberries (or frozen), dusted in 1 tablespoon flour flour will prevent them from sinking to bottom of the pan

For Optional Lemon Syrup

  • juice of 1 lemon mixed with 2-3 teaspoons sugar

For Simple Lemon Glaze

  • 1/2 cup icing sugar also called confectioners sugar or powdered sugar
  • juice from 1/2 lemon
  • dash of pure vanilla extract
  • Optional Garnish: Lemon zest to sprinkle on top

Instructions

  • GET ORGANIZED: Preheat oven temperature to 350F/176.7C. Spray an 8.5 x 4.5 x 2.5 inch loaf pan (21 x 11 x 6 cm) with cooking spray (or grease with butter) and dust with flour. Zest one large lemon and set aside (and a zest a second lemon to sprinkle on the finished loaf if you like).
  • COMBINE DRY INGREDIENTS: (except sugar) Whisk together flour, baking powder and salt in large mixing bowl.
    1 1/2 cups all-purpose flour, Note 1, 2 teaspoon baking powder, 1/2 teaspoon salt
  • COMBINE WET INGREDIENTS AND SUGAR: In a medium separate bowl, whisk sour cream eggs, sugar, lemon zest, vanilla and oil until smooth.
    1 cup sour cream, 1 cup sugar, 3 large eggs, 1 tablespoon lemon zest, 1/2 teaspoon vanilla extract, 1/2 cup vegetable or canola oil
  • COMBINE INGREDIENTS FROM BOTH BOWLS: Add wet mixture to dry ingredients and combine with whisk just until flour disappears. Don't overmix or the loaf will be dense. Gently fold in the blueberries dusted in flour with a spatula.
  • BAKE: Pour batter into greased/floured prepared pan. Bake on middle rack for about 50-70 minutes. A glass loaf pan will take longer than metal. Since ovens vary, start checking at 50 minutes. If toothpick or tester inserted into center of loaf comes out clean, it's done. Cool cake for 10 minutes on rack, then remove cake from loaf pan and place it on rack, top facing up, over a pan or cutting board (something to catch any drips if you are add the lemon syrup).
  • MAKE AND ADD LEMON SYRUP (OPTIONAL): For an even moister, more lemony loaf, poke holes in top of cake with tester or toothpick. Pour on lemon syrup to soak in. Let loaf cool completely on a wire rack.
  • MAKE AND ADD GLAZE: Mix together icing sugar and fresh lemon juice in a small bowl. After the loaf cools, drizzle glaze over cake. Sprinkle with lemon zest if desired. Slice and serve.

    1. HI Constance, As I mentioned in the FAQs: “Yes, you can use frozen blueberries. Do not thaw them. Toss frozen blueberries in flour to prevent them from bleeding too much into the batter”. I hope that helps!

  1. This lemon blueberry bread recipe is one of my favorite in every summer.๐Ÿ™‚ Itโ€™s moist, tender, and loaded with berries, and plenty of lemon zest gives it a pop of bright flavor. Thank you very much for sharing ๐Ÿ™‚. I enjoyed it!

    1. Hi Mary, I checked it out and yes, you can use 3/4 cup buttermilk to replace 1 cup of sour cream (because it’s thinner). Let us know how it turns out ๐Ÿ™‚

    The absolute best!!!! cooked in a glass loaf pan. Set the oven to convection bake at 325 instead of 350. Cooked for 95 minutes……definitely used the Lemon Syrup after it sat for about 10 min. This was perfection!!!

    I made this loaf for a refreshment needed for a meeting; I received so many compliments! The loaf was moist, kept its shape when I precut slices and had a beautiful presentation.

    Honestly, this was the best lemon, blueberry loaf I have ever tasted. It is also extremely easy and quick to make definitely would make again.

    1. Hi Margaret. A couple of things come to mind if you found the loaf soggy. Most oven temperatures are inaccurate so is it possible your loaf was a bit underbaked? You can buy an inexpensive thermometer for your oven to check the temperature. Also, it’s important to let the loaf cool before adding the syrup and glaze. The lemon syrup will definitely make the loaf very moist – you can omit that next time if you found it was too moist. Finally, blueberries that are very juicy can release more liquid. Make sure you dust them in flour before adding them or even add a touch (only a touch) more flour to the batter. I hope that helps.

    Have made this loaf twice now & it is absolutely moist & so delicious! Did pour about 3 or 4 tbsp of lemon juice into the batter along with the rind! Thank you for sharing๐Ÿ‘
