Zucchini Cake for Eid Ul Adha

Like what I mentioned before, it's my sort of "tradition" to bake a cake during eid. Last Eid-Ul-Adha, I baked a zucchini cake. It's my 5th time to try this, using the same recipe but until now, i can't still perfect. Sometimes, if i baked two pans, one will turn out okay while the other one will be not perfectly done. I still have to find the culprit for that.

I gave the zucchini cake with walnuts to our host in Sylhet and the one with blueberries, we ate it during the trip.
Bon apetit!
