Preheat oven to 350 degrees. Line 9 x 5 loaf pan with parchment paper. I spray the pan with a little cooking spray to keep the paper in place.
In a medium sized bowl whisk the flour, baking powder and salt together and set aside.
In a large mixing bowl mix the sugar and lemon zest by rubbing the zest into the sugar with your fingers. This releases the lemon flavor.
Add butter to the sugar and stir together.
Add eggs, one at a time, stirring after each addition.
Add buttermilk and lemon juice and stir well.
Mix half flour into wet ingredients, then add other half of flour and stir until just combined.
Pour batter into prepared loaf pan. Bake for about 40 minutes or until a toothpick comes out clean. Loaf should be starting to crack on top.
Cool in pan for 10 minutes then remove to a cooling rack and cool completely.
Make glaze by mixing the confectioners sugar and 2-3 tbsp lemon juice. Add juice 1 tbsp at a time until the glaze is fairly thick and spreadable.
Pour glaze over the top of the lemon loaf and spread out evenly.
Slice and enjoy!!
NOTES: *Use fresh lemons only - bottled juice won't hit the same. Meyer lemons are the best if you can find them. If not, regular lemons are also good. *For extra lemon punch, make glaze thinner. Poke holes in the loaf while still warm and pour the glaze over the top so it soaks into the bread. *Add blueberries, poppy seeds or chopped nuts. *Make mini loafs for gift giving.
