Step 1

Preheat your oven to 325°F (162°C) and prepare a 9x5-inch loaf pan with non-stick cooking spray.

Step 2

Whisk together the dry ingredients - all purpose flour, salt, baking soda, and baking powder - in a medium bowl and set aside.

Step 3

In a large bowl, cream together the unsalted butter and granulated white sugar until light and fluffy.

Step 4

Beat in the eggs one at a time, mixing well after each addition until fully incorporated.

Step 5

Stir in the lemon zest, lemon juice, and vanilla extract.

Step 6

Gradually add the dry ingredients to the wet ingredients, alternating between the dry ingredients and sour cream. Begin and end with the dry ingredients, mixing until just combined. Be careful not to overmix.

Step 7

Pour the batter into the prepared loaf pan and smooth it out evenly.

Step 8

Bake in the preheated oven for about 45-55 minutes or until a toothpick inserted into the center of the loaf comes out clean.

Step 9

Once the loaf is done baking, remove it from the oven and let it cool in the pan for about 10 minutes.

Step 10

While the loaf is cooling, prepare the glaze by whisking together the powdered sugar, lemon juice, whole milk, melted butter, salt and vanilla extract until smooth.

Step 11

Transfer the loaf to a wire rack placed over a baking sheet or parchment paper.

Step 12

Spoon the glazer over the slightly warm loaf, allowing it to cover the loaf.

Step 13

Let the loaf cool completely and the glaze dry before slicing and serving. Enjoy!
