Start by preheating your oven to 350°F (175°C) and lining a standard loaf pan with parchment paper, leaving a bit of overhang on the sides for easy removal later.
In a large mixing bowl, add the sugar and zest one fresh lemon directly over it. Use your fingers to massage the zest into the sugar for about a minute.
1 cup Sugar, 2 tbsp. Lemon Zest
Next, pour in the melted (but slightly cooled) butter, followed by the eggs, lemon juice, milk, and Greek yogurt. Whisk everything together until the mixture is smooth and well combined.
1/2 cup Butter, 2 tbsp. Lemon Juice, 2 Large Eggs, 1/2 cup Milk, 1/4 cup Greek Yogurt
In a separate bowl, whisk together the flour, baking powder, and salt.
1&1/2 cup Flour, 1 tsp. Baking Powder, 1/2 tsp. Salt
Gradually add the dry ingredients to the wet mixture, stirring just until everything is incorporated—don’t overmix.
If you’re using frozen blueberries, toss them in about a tablespoon of flour before gently folding them into the batter. This helps prevent them from sinking to the bottom of the loaf while baking.
1 cup Frozen Blueberries
Pour the batter into your prepared loaf pan and smooth out the top. Bake for 50 to 55 minutes, or until the top is golden and a toothpick or knife inserted into the center comes out clean.
If the top begins to brown too quickly, you can loosely tent it with foil during the last 10–15 minutes of baking. Once done, let the loaf cool in the pan for about 10 minutes before transferring it to a wire rack to cool completely.
