Banana Upside Down Cake

Made just like a normal banana cake, but first sprinkle red/brown sugar at the bottom of the tin, then lined sliced banana on top, followed by banana cake batter (with mashed banana in the batter). The most moist banana cake I have ever had, and took less than 15 minutes to prepare, and only about 45 minutes in the oven. I think I got the recipe online from bestrecipes.com.au, but can't seem to find it now.
