Forgot to add that these also make great bar cookies! We normally make them as round cookies but the last few times we decided to make them in a bar pan and loved them. No more waiting for the first batch to bake and cool...get its done in one go round!!
My kids and I (and my coworkers and neighbors!) love this! I use 4-5 bananas and add cinnamon and up to 2 tsp oil. I also use egg beaters or just egg whites. You can't tell it's "healthy" and whenever I make this, it's gone in no time flat!!
