Preheat the oven to 350F/180C. In a large mixing bowl, rub the lemon zest and sugar together until it resembles coarse sand.
1 (200 g) cup Granulated sugar, 2 tablespoons Fresh lemon zest, 1 ¾ (219 g) cups Cake flour, 2 teaspoons Baking powder, ¼ teaspoon Baking soda, ½ teaspoon Kosher salt
To the bowl with the lemon sugar, sift in the cake flour, baking powder, baking soda, and salt. Then, whisk every thing together until combined.
In a separate medium mixing bowl, whisk together the room temperature sour cream and eggs for 30 seconds. Next, whisk in the cooled melted butter, whole milk, lemon juice, and vanilla extract until combined.
2 large Eggs, ¾ (180 g) cup Sour cream, ½ (113 g) cup Unsalted butter, ¼ (60 g) cup Whole milk, 2 tablespoons Fresh lemon juice, ½ teaspoon Vanilla extract
Add the wet ingredients to the sugar/flour mixture and gently fold the two together with a rubber spatula until just combined. After mixing, the batter will be thick and lumpy. Don't worry, that is expected.
Spray a 9x5 loaf pan with non stick baking spray and line the long side of the pan with parchment paper. The parchment paper should make a sling and hang off the sides for the pan for easy removal. Spoon the batter into the prepared pan and smooth the top with the back of a spoon or offset spatula. Tap the pan a few times on the counter to remove any air bubbles.
Bake the lemon bread for 45 - 50 minutes or until a toothpick or skewer inserted in the center comes out clean. When done, the skewer should come out clean or a few moist crumbs but no wet batter.
Allow the lemon bread to sit in the pan on a cooling rack for 10 minutes. Then, using the parchment overhang, lift the bread out of the pan and place onto the cooling rack. Let the bread cool completely before glazing.
Once cooled, in a medium mixing bowl whisk together the sifted powdered sugar, lemon juice, and lemon zest. Pour the lemon glaze over the top of the cooled lemon bread and top with extra lemon zest if desired. Allow the glaze to set for 10 minutes then slice and enjoy!!
