vegan banana bread

Today we baked some vegan banana bread.  I didn't have my usual recipe, so I used a new one.  I followed it well except for I used all brown sugar--I couldn't find any white.  And it sort of burned.  It was sort of burning and I took it out and it was still raw inside!  So I turned the heat down to 250 and let it sit in the oven for a while like that.  And I checked it again and it was cooked.  So I guess the moral of the story is that molasses burns.  But it's got a good flavor otherwise.
