This easy lemon blueberry bread is light, buttery, and bursting with juicy blueberries and bright lemon flavor. One bowl, no stand mixer, 10 minutes of prep — and a crunchy sugar topping that makes it look completely bakery-worthy. Made with a half whole wheat flour blend for a slightly heartier, more nutritious crumb.
1cup(125g) all-purpose flourplus 1 tablespoon for flouring the berries
1cup(125g) whole wheat flour
2teaspoonsbaking powder
½teaspoonsalt
⅔cup+ 1 tablespoon granulated white sugardivided
⅓cupunsalted buttermelted and cooled for 1-2 minutes
2largeeggsbrought to room temperature
¾cupfull-fat sour creamor plain Greek yogurt (2% or 4%), at room temperature
3tablespoonsfresh lemon juice(about 1 lemon)
1tablespoongrated lemon zest(about 1 lemon)
1teaspoonpure vanilla extract
1 ¼cupsfresh or frozen blueberries
Instructions
Preheat the oven to 350°F. Grease an 8x4-inch loaf pan with nonstick spray or butter.
In a large mixing bowl, whisk together both flours, baking powder, salt, and ⅔ cup sugar until combined.
Add the eggs, sour cream, melted butter, lemon juice, lemon zest, and vanilla extract. Whisk until just combined.
In a small bowl, toss the blueberries with 1 tablespoon flour until lightly coated. Sprinkle over the batter and fold in gently with a rubber spatula until just combined. (If using frozen blueberries, stop folding as soon as they're distributed to minimize streaking.)
Pour the batter into the prepared loaf pan. Sprinkle the remaining 1 tablespoon sugar evenly over the top.
Bake for 50–60 minutes, until a toothpick inserted into the center comes out clean and the top is golden brown.
Transfer the pan to a wire rack and cool for 5–10 minutes. Turn the loaf out of the pan and cool to room temperature before slicing.
Notes
Measure flour by weight (125g per cup) or spoon and level — never scoop directly from the bag. Too much flour = dense bread.
Fresh or frozen blueberries Both work. No thawing needed for frozen. Toss in flour either way.
Blueberry sinking fix: Toss blueberries in 1 tbsp flour before folding in — keeps them suspended throughout the loaf instead of sinking to the bottom.
Sour cream substitute: Full-fat plain Greek yogurt at a 1:1 ratio.
Whole flour substitute: Use 2 cups (250g) all-purpose flour or 2 cups whole wheat pastry flour in place of the half-and-half blend.
Lemon glaze (optional): Whisk 1 cup powdered sugar + 2 tbsp lemon juice + 1 tsp lemon zest. Drizzle over fully cooled loaf.
Muffins: Fill greased muffin tins ¾ full, bake at 375°F for 18–22 minutes. Makes 12.
Storage: Room temperature up to 2 days; refrigerate up to 3–4 days; slice and freeze wrapped in parchment or plastic wrap up to 3 months.
