Moist, buttery, and tangy lemon loaf bursting with fresh lemon zest and juice, finished with a sweet-tart lemon glaze. Cozy bakery flavor that’s perfect for breakfast, dessert, or an afternoon pick-me-up—better than store-bought when it’s warm from your oven.
Preheat oven to 350°F (175°C). Grease and flour a 9×5-inch loaf pan or line with parchment for easy release.
Whisk dry ingredients: In a medium bowl, whisk together flour, baking powder, and salt; set aside.
Cream butter and sugar: In a large bowl, beat softened butter with granulated sugar until light and fluffy, 2–3 minutes.
Add eggs: Beat in eggs one at a time, scraping the bowl as needed until fully combined.
Add wet flavorings: Mix in sour cream, milk, lemon juice, lemon zest, and vanilla until smooth.
Combine: Add the dry ingredients to the wet mixture and stir just until combined; do not overmix.
Bake: Pour batter into the prepared loaf pan and smooth the top. Bake 50–60 minutes, or until a toothpick inserted in the center comes out clean (start checking at 45 minutes). Tent with foil if browning too quickly.
Cool: Let the loaf cool in the pan for 10 minutes, then transfer to a wire rack to cool completely.
Glaze: In a small bowl, whisk powdered sugar with lemon juice until smooth and pourable. Drizzle over the fully cooled loaf and let set before slicing.
