1 ¼cupsblueberries180g; fresh or frozen (do not thaw if frozen)

1cuppowdered sugar120g; sifted
2-3tbspfresh lemon juiceadjust for desired glaze consistency
Instructions
Preheat oven to 350°F (175°C). Grease a 9x5-inch loaf pan, then line with parchment paper leaving a 1–2 inch overhang on both long sides for easy removal.
Add blueberries to a small bowl, sprinkle with 1 tablespoon of flour, and toss gently until lightly coated. Set aside — this prevents the berries from sinking to the bottom during baking.
In a medium bowl, whisk together the flour, baking powder, baking soda, and salt for about 30 seconds until evenly combined. Set aside.
In a large bowl, combine the sugar and lemon zest, then rub them together with your fingertips for 30–60 seconds to release the citrus oils. Whisk in the eggs, oil, sour cream, lemon juice, and vanilla until smooth and uniform.
Pour the dry ingredients into the wet ingredients and fold gently with a rubber spatula just until the flour streaks disappear — about 12–15 folds. Do not overmix; the batter will be thick.
Add the flour-coated blueberries to the batter and fold in gently with 3–4 slow strokes, just until evenly distributed without bursting the berries.
Pour the batter into the prepared pan, smooth the top, and bake on the center rack for 55–60 minutes, or until a toothpick inserted in the center comes out clean. Tent loosely with foil at 40 minutes if the top browns too quickly.
Let the loaf cool in the pan for 10–15 minutes, then lift out using the parchment overhang and transfer to a wire rack. Cool for at least 30–45 more minutes before slicing.
Whisk sifted powdered sugar and 2 tablespoons of lemon juice together until smooth and thick but pourable, adding the third tablespoon if needed. Drizzle over the fully cooled loaf and let set for 10–15 minutes before serving.
Notes
Room temperature matters: Pull eggs and sour cream out of the fridge 20–30 minutes before baking for a smoother, more evenly mixed batter.
Zest before juicing: It's much easier to zest a whole lemon than a juiced one — always zest first, then cut and squeeze.
Rub zest into sugar: Don't skip this step — rubbing lemon zest into the granulated sugar with your fingertips releases its natural oils and dramatically deepens the lemon flavor.
Do not overmix: Fold the batter only until the flour just disappears. Overmixing develops gluten and leads to a dense, tough loaf.
Frozen blueberries tip: Use frozen blueberries straight from the freezer — do not thaw first. Thawed berries release too much liquid and can turn the batter an unappetizing color.
Check doneness early: Oven temperatures vary, so start testing with a toothpick at the 50-minute mark rather than waiting the full 60 minutes.
Glaze consistency: For a glaze that sets firmly on top, keep it thick. For one that soaks into the loaf, thin it slightly with an extra teaspoon of lemon juice.
Storage: Store wrapped at room temperature for up to 3 days, refrigerated for up to 6 days, or freeze (unglazed) for up to 3 months. Individual slices can be frozen separately for easy grab-and-go portions.
Make into muffins: Divide the batter into a lined 12-cup muffin tin and bake at 375°F (190°C) for 18–22 minutes for a portable, single-serving version.
Reduce sugar: The sugar can be reduced to ½ cup (100g) without significantly affecting texture, though the loaf will be less sweet. Coconut sugar substitutes at a 1:1 ratio for a subtle caramel depth.
