Preheat oven to 375 degrees. Grease an 8x5 loaf pan
Whisk together the flour, baking powder, baking soda, salt, cardamom and lemon zest. Toss the chopped dates in 1 tbsp of the flour mixture. This will stop them from clumping together in the batter.
In another bowl, beat together the oil, sugar and honey until well blended. Add the eggs, one at a time, mixing between each addition.
Add the wet ingredients to the flour mixture and stir together until just mixed. Fold in the zucchini and the dates.
Pour the batter into your prepared loaf pan and cook until a knife inserted into the center comes out clean. 45-55 minutes.
