Wholesome Ingredients for This Lemon Blueberry Loaf

Each ingredient in this loaf serves both a flavor and nutritional purpose. Here are some of the stars that make this dessert so satisfying and better-for-you:

Blueberries: These sweet little gems are packed with antioxidants and help keep the loaf moist. Feel free to substitute with frozen blueberries if fresh aren’t in season, though fresh always delivers the best texture!
Lemon Zest & Juice: Using both the zest and juice ensures every bite bursts with citrusy brightness. Meyer lemons work wonderfully if you have them on hand.
Butter: Traditional unsalted butter gives richness and structure. Swap with coconut oil for a dairy-free option, or try vegan butter for plant-based diets.
All-Purpose Flour: A pantry staple for a soft crumb. If you’re gluten-free, opt for a cup-for-cup GF alternative for an easy swap.

How to Make Lemon Blueberry Loaf

Start with the crumble topping. Combine melted butter, sugar, flour, and salt in a small bowl. Chill in the refrigerator until ready to use.
Preheat your oven to 350°F (175°C) and line a 1-lb loaf pan with parchment paper, greasing the sides well.
In a stand mixer, mix sugar and lemon zest, rubbing them together with your fingers to release aromatic oils.
Add in flour, baking powder, and salt. With the mixer on low speed, add butter, one tablespoon at a time, until crumbly.
Scrape down the sides of the bowl, then mix in vanilla extract and eggs one at a time. Blend in the lemon juice and milk until smooth.
Toss blueberries in flour to coat, then gently fold them into the batter until evenly distributed.
Transfer batter to the prepared loaf pan and sprinkle extra blueberries on top before adding the chilled crumble.
Bake for about 50-60 minutes, or until a toothpick inserted into the center comes out with moist crumbs. Let cool for 45 minutes before removing from pan.
For the icing, whisk powdered sugar, milk, and lemon juice to a drizzleable consistency. Pour over cooled loaf.
Slice and enjoy!

Our Team’s Tips for the Best Lemon Blueberry Loaf

Always coat your blueberries in flour to prevent them from sinking to the bottom of the loaf.
Use room-temperature ingredients to ensure the batter mixes smoothly.
Let the loaf cool completely before icing—warm cake will make the icing run!
Store your leftovers in an airtight container at room temperature for up to 3 days.
For a freezer-friendly option, wrap slices tightly in plastic wrap and store for up to 2 months.

Lemon Blueberry Loaf FAQs

Can I use frozen blueberries?

Yes, you can! Just be sure to toss the frozen berries in a tablespoon of flour and keep them frozen until just before mixing into the batter.

What makes this loaf so moist?

The combination of butter, milk, and the fresh juice from the lemon keeps this loaf tender and moist.

Can I substitute another fruit?

Absolutely! Diced strawberries or raspberries work great as alternatives to blueberries.

How do I prevent the loaf from sinking in the middle?

Ensure your oven is fully preheated, and avoid opening the door until at least 45 minutes into baking to maintain consistent heat.
