Made this today. It was easy and fast and delicious. All the guests and family loved it and asked for seconds. I might double the banana next time just for more richness, but it doesn't need it at all. I also added about 1/2 Tbsp almond extract. The recipe is definitely one to keep.
Made this cake today, and it is delicious. I love the texture, crumb and flavor the olive oil imparts. It provides a richness that you don't get with vegetable oil. I've only made a few cakes with olive oil, but I love them. I didn't have 2/3 cup of maple syrup, so I used 1/3 honey and 1/3 maple syrup. It is a simple, delicious cake.
