My mom makes the best banana cake. A few years ago she sent me the recipe and I have adapted it to be vegan and now gluten free. Its delicious right out of the oven. She sometimes ices it with chocolate but its not necessary (unless you love chocolate and can't live without it.)
This is a great way to use up your over ripe bananas. Just throw them in the freezer when they start to get to ripe and then thaw them when you want to make the cake!
