How to Make Blueberry Loaf Cake

This is one of those recipes that looks like it took a lot of effort, but really comes together in under 20 minutes before baking. Here’s the simple step-by-step:

1. Preheat & Prep

Preheat your oven to 350°F (175°C). Grease and line a 9×5-inch loaf pan with parchment paper, leaving a little overhang for easy removal.

2. Mix the Dry Ingredients

In a medium bowl, whisk together the flour, baking powder, baking soda, and salt. Set aside.

3. Cream Butter and Sugar

In a large mixing bowl, beat the softened butter and granulated sugar until light and fluffy—about 2 to 3 minutes with a hand or stand mixer. This step adds air to the batter and makes the loaf nice and soft.

4. Add Eggs and Flavor

Beat in the eggs one at a time, mixing well after each. Stir in the vanilla extract and lemon zest. The zest adds a subtle citrus flavor that lifts the whole loaf.

5. Mix in the Sour Cream

Stir in the sour cream (or Greek yogurt) until smooth. It’s what gives this cake its moist, tender crumb.

6. Combine Wet and Dry

Gradually add the dry ingredients to the wet, mixing gently until just combined. Avoid overmixing—it can make the loaf tough.

7. Prep the Blueberries

Toss the blueberries with 1 tablespoon of flour to help prevent them from sinking to the bottom. Fold them gently into the batter using a spatula.

8. Bake

Pour the batter into your prepared loaf pan and smooth the top. Bake for 50–60 minutes, or until a toothpick inserted in the center comes out clean. If the top starts browning too quickly, loosely cover it with foil around the 35-minute mark.

9. Cool

Let the loaf cool in the pan for 10–15 minutes, then transfer it to a wire rack to cool completely before glazing.

10. Glaze

In a small bowl, whisk together the powdered sugar and lemon juice until smooth. Drizzle it over the cooled loaf and garnish with extra lemon zest if desired.

Tips, Variations & Substitutions

Can I Use Frozen Blueberries?

Absolutely! Use them straight from the freezer—no need to thaw. Just toss them in flour as you would with fresh berries to prevent bleeding or sinking.

Want a Sweeter Loaf?

You can add a tablespoon or two of honey, or replace part of the granulated sugar with light brown sugar for a deeper, almost caramel-like sweetness.

No Lemon on Hand?

The lemon zest and glaze are optional, but they really elevate the flavor. If you don’t have fresh lemons, a touch of lemon extract (just 1/4 tsp) can work in a pinch.

Add-Ins to Try:

• Poppy seeds – for a fun texture and a nod to lemon-poppyseed muffins
  
• Chopped almonds or walnuts – adds a bit of crunch
  
• Coconut flakes – for a tropical twist
  

When to Serve It

This blueberry loaf cake is versatile enough for any time of day:

• Morning: Enjoy a slice with coffee or tea
  
• Brunch: Serve alongside savory dishes for a sweet finish
  
• Gifting: Wrap in parchment and tie with twine for a thoughtful homemade gift
  
• Dessert: Top with whipped cream or a scoop of lemon ice cream for an easy treat
