I substituted homemade cinnamon applesauce for the oil (simmer one gala apple cut in thin slices in a bit of water with cinnamon then puree into applesauce) and upped the vanilla to a full tablespoon. These cookies turned out amazing and soooo delicious! My husband doesn't love chocolate like I do, so I made half the batch with chips and half without. Yum, both versions were really really good. Thank you!
