- Lower the oven rack to the lower-third position and preheat to 350°F (177°C) while greasing your loaf pan. This ensures the dense batter cooks evenly without burning the top.
- Whisk the flour, baking powder, and salt together in a large bowl. This distributes the leavening agent so the cake rises uniformly.
- Beat the softened butter on high speed for 1 minute, then add sugar and beat for 2 minutes until creamy. This process incorporates air for a lighter texture.
- Add eggs one at a time, followed by sour cream, lemon juice, zest, and vanilla, beating on medium speed. The mixture might look curdled, but it will smooth out once flour is added.
- Slowly add the dry ingredients to the wet mixture with the mixer on low speed just until combined. Stop mixing as soon as the flour disappears to prevent a tough cake.
- Spoon the thick batter into the pan and bake for 45–65 minutes, tenting with foil halfway through. The cake is ready when a toothpick inserted in the center comes out mostly clean.
- Cool the cake in the pan for 1 hour before removing it to a wire rack. Cooling stabilizes the structure so it doesn't fall apart when moved.
- Whisk the icing ingredients together and pour over the cooled cake. Allow the glaze to set slightly before slicing for neat edges.

Notes
Room temperature ingredients are crucial for a smooth batter; if the mixture looks curdled before adding flour, don't worry as it will come together. Tent with foil halfway through baking if the top browns too quickly.
