adventures in cooking: banana bread

I recently tried my hand at banana bread. It was delicious for about 2 pieces (pretty much just those pictured) until I got to the middle which was uncooked. Oddly enough it was the very top of the bread that remained doughy. My vintage oven tends to be unnaturally warm so I have a tendency to overcook items. Things coming out raw is a new problem for me.

I got the recipe from my go-to cookbook, How to Make Everything. Breads may not be my forte either.
