Once your banana bread is out of the oven, you have to let it cool a bit before slicing. I know it's a complete pain isn't it? Wait you must, as horrendous as that is, but you can slice it while it's still a little warm. Let's face it you're not going to wait until it's completely cool. That smell is wafting around the house and it look so good. Once sliced it needs a good layer of dairy free butter and then you need absolute peace to enjoy it and another slice or two. So make sure you warn everyone to go do something else until you call them.
