This is DELICIOUS. I only use 3 bananas and it's perfect. In fact, I've made this exact recipe probably close to 10 times now. I tried 4 bananas once and it was heavy. Cooked the first 30 minutes then covered and cooked the 25 minutes. I used the smaller amount of sugar that it called for. I've added chocolate chips and walnuts to it as well which is yummy.
