Preheat oven to 325 degrees F. Grease a 9x5 inch loaf pan. Set aside.
In a medium bowl, whisk together flour, baking powder, salt, and lemon rind. Set aside.
In the bowl of an electric stand mixer with the paddle attachment, cream butter until light and fluffy.
Scrape down the sides of the bowl. With the mixer on low, gradually add in your sugar. Mix for approximately 1 minute. Scrape down the sides of the bowl again.
With the mixer on low, add in the eggs one at a time allowing each to incorporate before the next addition. Scrape down the sides of the bowl. Add in lemon juice and mix until combined.
With the mixer on low speed, add your dry ingredients to the creamed mixture alternately with milk and lemon juice.
Pour into greased loaf pan.
Bake for 60-65 minutes or until the loaf is cooked through. Test by placing a toothpick in the centre of the loaf. If it comes out clean, your loaf is complete.
Allow to cool completely in the pan before removing.
Make lemon cream cheese frosting.
