What Makes This Loaf Cake So Moist?

Fresh Lemon Juice and Zest
Using both lemon zest and juice provides layers of citrus flavor without making the cake overly tart.
Ingredients
For the Loaf Cake
- Zest of 2 lemons
- 1 cup granulated sugar
- 1/2 cup olive oil
- 1 teaspoon vanilla extract
- 2 large eggs
- 1/2 cup plain yogurt or sour cream
- 2 tablespoons fresh lemon juice
- 2 teaspoons baking powder
- 1/2 teaspoon kosher salt
- 1 1/2 cups all-purpose flour
- 1 cup fresh blueberries
For the Topping
- 1/2 cup fresh blueberries
- 1 1/2 tablespoons turbinado sugar
How to Make Lemon Blueberry Loaf Cake
Step 1: Prepare the Pan
Preheat your oven to 350°F.
Grease a standard 9×5-inch loaf pan or line it with parchment paper for easy removal.
Step 2: Infuse the Sugar
In a large mixing bowl, combine the lemon zest and sugar.
Using your fingertips, rub the zest into the sugar until the mixture becomes fragrant and slightly moist.
This simple step releases the natural oils from the lemon zest and intensifies the citrus flavor throughout the cake.
Step 3: Mix the Wet Ingredients
Add:
- Olive oil
- Vanilla extract
- Eggs
- Yogurt or sour cream
- Lemon juice
Whisk until smooth and fully combined.
Step 4: Add the Dry Ingredients
Mix in:
- Baking powder
- Kosher salt
- Flour
Stir gently until no dry streaks remain.
Be careful not to overmix. Overmixing can result in a dense loaf instead of a tender crumb.
Step 5: Fold in the Blueberries
Gently fold in 1 cup of blueberries.
Use a spatula and mix just enough to distribute them evenly throughout the batter.
Step 6: Fill the Loaf Pan
Pour the batter into the prepared loaf pan and smooth the top.
Scatter the remaining 1/2 cup blueberries over the surface.
Sprinkle evenly with the turbinado sugar.
The sugar creates a lightly crisp, sparkling crust that gives the loaf a beautiful bakery-style finish.
Step 7: Bake
Bake for 45 to 55 minutes.
The loaf is done when:
- The top is golden brown
- A toothpick inserted into the center comes out clean
- The center springs back lightly when touched
If the top begins browning too quickly, loosely tent with aluminum foil during the final 10 minutes of baking.
Step 8: Cool
Allow the loaf to cool in the pan for 15 minutes.
Transfer to a wire rack and cool completely before slicing.
Tips for Perfect Lemon Blueberry Loaf Cake
Use Fresh Lemons
Fresh lemon zest provides the brightest flavor and aroma.
Don’t Overmix
Mix only until the flour disappears to keep the crumb light and tender.
Coat Blueberries If Needed
If using frozen blueberries, toss them lightly with a tablespoon of flour before folding them into the batter to prevent sinking.
Let the Cake Cool
Allowing the loaf to cool completely helps the flavors develop and makes slicing easier.

Can I use frozen blueberries?
Yes. Add them directly from frozen and avoid thawing to prevent excess moisture.
Can I substitute vegetable oil?
Yes, but olive oil provides a richer flavor and more tender texture.
Why did my blueberries sink?
The batter may have been too thin or the berries too large. Tossing them in a little flour can help.
