My own creation, born of the love of all things cinnamon and banana...Easy and soooo satisfying! Lovely, sweet bits of banana in a tender cream cheese and cinnamon coffee cake with a bit of streusel. It is definitely not for those without a sweet-tooth! **You can easily double this recipe and put it in a 9x13 inch pan, increasing baking time to 50-60 minutes. If you do double, add eggs one at a time, beating after each addition until well combined. You can also use a blueberry-banana combo (1 cup blueberries, 1 banana for a double recipe), though you might want to increase the sugar in the batter by 1/4 cup.
