Lemon Blueberry Loaf Cake with Glaze

This lemon blueberry loaf cake is a recipe you’ll find yourself making on repeat. It’s incredibly moist, tender, and packed with bursts of blueberry in every bite.

The real finishing touch, though, is the sweet-tangy lemon glaze that soaks into the top and adds that bakery-style look and flavor.

Whether you’re baking for a weekend brunch, an afternoon snack, or a simple homemade dessert, this loaf cake delivers big flavor with minimal effort.

Ingredients You’ll Need

For the Loaf Cake

• All-purpose flour
• Baking powder
• Salt
• Unsalted butter (or neutral oil)
• Granulated sugar
• Eggs
• Fresh lemon juice
• Lemon zest
• Milk or yogurt
• Fresh or frozen blueberries

For the Lemon Glaze

• Powdered sugar
• Fresh lemon juice

Each ingredient plays an important role. The lemon juice and zest provide that bold citrus flavor, while the blueberries add natural sweetness and moisture. The glaze ties everything together with a smooth, tangy finish.

How to Make Lemon Blueberry Loaf Cake

Start by preheating your oven to 175°C (350°F) and lining a loaf pan with parchment paper. This makes it easier to remove the cake after baking.

In one bowl, whisk together the flour, baking powder, and salt. This ensures the leavening is evenly distributed.

In a separate bowl, cream the butter and sugar until light and fluffy. This step helps create a soft, airy texture. Add the eggs one at a time, mixing well after each addition. Then stir in the lemon juice and zest.

Next, alternate adding the dry ingredients and the milk or yogurt into the wet mixture. Mix gently until just combined—overmixing can make the loaf dense.

Toss the blueberries with a small amount of flour to prevent them from sinking, then gently fold them into the batter.

Pour the batter into the prepared pan and smooth the top. Bake for 50–60 minutes, or until a toothpick inserted in the center comes out clean.

Allow the loaf to cool completely before adding the glaze.

How to Make the Perfect Lemon Glaze

Making the glaze is simple but makes a big difference. In a small bowl, whisk together powdered sugar and fresh lemon juice until smooth.

If the glaze is too thick, add a little more lemon juice. If it’s too thin, add more powdered sugar. You’re aiming for a pourable consistency that will drizzle nicely over the cake.

Once the loaf is completely cool, drizzle the glaze over the top. Let it set for about 10–15 minutes before slicing. For extra flavor and presentation, you can sprinkle a bit of lemon zest on top.

Tips for the Best Lemon Blueberry Loaf

For the best results, use fresh lemon juice and zest rather than bottled. The flavor is much brighter and more vibrant.

Be careful not to overmix the batter. Stirring too much can lead to a dense loaf instead of a soft, tender crumb.

Coating the blueberries in flour helps keep them evenly distributed throughout the cake rather than sinking to the bottom.

Using room temperature ingredients ensures everything mixes smoothly and evenly.

Finally, let the loaf cool completely before slicing. This helps it set properly and prevents it from crumbling.

Variations and Substitutions

This recipe is easy to adapt based on your preferences or what you have on hand. You can swap blueberries for raspberries or blackberries for a slightly different flavor.

If you want a richer texture, use Greek yogurt instead of milk. For a dairy-free version, substitute plant-based butter and milk alternatives.

You can also turn this recipe into muffins by dividing the batter into a muffin tin and reducing the baking time.

For added texture, consider topping the loaf with a simple crumb topping before baking. Or, for a slightly healthier twist, replace part of the flour with whole wheat flour.

How to Store and Freeze Lemon Blueberry Loaf Cake

Store the loaf in an airtight container at room temperature for up to three days. If you want it to last longer, refrigerate it for up to five days.

To freeze, wrap the loaf or individual slices tightly in plastic wrap and place them in a freezer-safe bag. It will keep well for up to three months.

When ready to enjoy, thaw at room temperature. The loaf will taste just as moist and flavorful as the day you made it.

Serving Ideas and Pairings

This lemon blueberry loaf cake pairs beautifully with a hot cup of coffee or tea. It also works well as part of a brunch spread alongside fresh fruit and yogurt.

For dessert, you can serve it with a dollop of whipped cream or a scoop of vanilla ice cream. If you prefer it warm, gently heat a slice in the microwave for a few seconds before serving.

No matter how you serve it, the combination of lemon and blueberry always feels fresh and satisfying.
