  2. In a medium bowl whisk together the flour, baking powder, baking soda, and salt.
  3. In a large bowl mix together the sugar and lemon zest, really whisk the lemon zest into the sugar, this helps the natural oils and flavor of the zest meld into the sugar. Add the vegetable oil next whisking to combine. Add the eggs and mix until fully incorporated. Add the shredded zucchini and lemon juice. Gently fold in the flour mixture, just until no flour streaks remain. 
  4. Pour the batter into the prepared pan. Bake for approximately 43-50 minutes, or until a toothpick inserted comes out clean with no wet batter. Let it cool on a wire rack for at least 30 minutes before inverting to cool completely.
  5. In a small bowl mix together the powdered sugar, lemon zest, heavy cream, and lemon juice. Add more powdered sugar if you want a thicker frosting or more lemon juice if you want a thinner frosting. Spread on top of cooled cake. Store leftovers. in an air-tight container.
