This easy cake is a great way to use those abundant summer zucchini. It has a crunchy cinnamon streusel that you'll want more of and the crumb is fluffy and bursting with grated zucchini.
Sift over it flour, baking powder, baking soda and cinnamon. Or have the dry ingredients sifter in a different bowl and add to the egg batter. Mix well but don't overmix.
