Skip the coffee shop and make this Copycat Starbucks Lemon Loaf at home. Packed full of fresh, zingy lemon flavor & topped with a simple glaze, it will quickly become your new favorite treat.
Preheat oven to 350 degrees. Grease a loaf pan, set aside.
In the bowl of a stand mixer, cream the butter. Add the sugar and cream for 3 minutes, until light. Add eggs one at a time, mixing between each addition. Add vanilla, sour cream, lemon zest and lemon juice. Mix until smooth. Add baking soda, kosher salt and flour then mix until just combined.
Pour batter into the prepared loaf pan and spread the top evenly. Bake for 45 to 55 minutes, until a toothpick comes out clean. If it starts to brown too much, lay a piece of foil on top (don't seal it on the pan as the loaf may continue to rise).
Remove from the oven and let cool for 10 minutes then remove to a cooling rack to completely cool.
Once cool, whisk together the powdered sugar and lemon juice. Drizzle over the cooled loaf.
