This lemon blueberry loaf is sunshine in dessert form! It has a bright citrus flavor and juicy bursts of blueberries, all wrapped up in a soft, buttery loaf. The sugary lemon glaze ties everything together, making each slice even more indulgent. Simply make the batter, fold in the blueberries, bake, and this delightful dessert is yours!
Preheat to 325 °F. Grease a 9x5-inch loaf pan or line with parchment paper.
Beat the butter in a large bowl with an electric mixer while slowly adding the sugar. Cream together well.
Beat in one egg yolk at a time. Add the lemon juice and zest.
In a separate bowl, sift the flour and baking powder. Then slowly mix into the batter on the lowest speed until just combined.
Whip egg whites in the now empty flour bowl until stiff peaks form. Fold into the batter.
Pour a few inches of batter into the loaf pan. Then, gently fold the blueberries into the remaining batter.
Pour the rest of the batter into the pan and bake for 50-60 minutes, or until a toothpick inserted in the center comes out clean.
Let the loaf cool in the pan for 10 minutes, then transfer to a wire rack.
Whisk the glaze ingredients until smooth. Drizzle over the cooled loaf before slicing.

Notes
Make sure that your ingredients are at room temperature for a smoother batter and better incorporation of ingredients.
When zesting your lemons, make sure to only remove the yellow part of the peel. The white pith underneath can be bitter and may affect the flavor of your loaf.
Overmixing can make the loaf thick and dense. Combining the wet and dry ingredients until they are just barely incorporated to make a very light and fluffy crumb texture.
If the glaze is too thick, add more lemon juice, 1 teaspoon at time, until it reaches a pourable consistency.
Serve: Serve with a dollop of whipped cream or a scoop of vanilla ice cream. For a lighter touch, enjoy with a fresh fruit salad, a side of yogurt, or a warm cup of tea or coffee.Store: Place loaf in an airtight container and store at room temperature for up to 3 days, or keep in the refrigerator for up to 5 days. To freeze, transfer to a freezer-safe container and keep in the freezer for up to a month. To thaw, let them sit at room temperature for an hour or two.
