Ingredients
For the Loaf:
- 1½ cups (190 g) all-purpose flour
- 1 tsp baking powder
- ¼ tsp baking soda
- ¼ tsp salt
- ½ cup (115 g) unsalted butter, softened
- ¾ cup (150 g) granulated sugar
- 2 large eggs
- 2 tbsp lemon zest (from about 2 lemons)
- 3 tbsp lemon juice (freshly squeezed)
- ½ cup (120 ml) sour cream or Greek yogurt
- 1 tsp vanilla extract
- 1 cup (150 g) fresh or frozen blueberries
- 1 tbsp flour (for coating the blueberries)
For the Lemon Glaze:
- ½ cup (60 g) powdered sugar
- 1–2 tbsp lemon juice (adjust for consistency)
Instructions
- Preheat oven to 350°F (175°C).
Grease and line a 9×5-inch loaf pan with parchment paper. - Mix dry ingredients:
In a bowl, whisk together flour, baking powder, baking soda, and salt. Set aside. - Cream butter and sugar:
In a large bowl, beat the butter and sugar until light and fluffy (2–3 minutes). - Add eggs and flavor:
Beat in eggs one at a time, then add lemon zest, lemon juice, sour cream, and vanilla extract. Mix until smooth. - Combine wet and dry:
Gently fold the dry ingredients into the wet mixture until just combined. Don’t overmix. - Add blueberries:
Toss blueberries with 1 tbsp flour, then fold them gently into the batter. - Bake:
Pour batter into the prepared pan.
Bake for 50–60 minutes, or until a toothpick comes out clean. - Cool and glaze:
Let loaf cool 10 minutes in the pan, then transfer to a rack.
Mix powdered sugar with lemon juice to make a smooth glaze.
Drizzle over the cooled loaf.
Tips:
- Coat the blueberries in flour so they don’t sink to the bottom.
- For a stronger lemon flavor, poke small holes in the warm loaf and drizzle lemon syrup (lemon juice + sugar).
- Store covered at room temp for 2 days or refrigerate up to 5 days.
