I found this yummy recipe on Pinterest, which linked me HERE. This turned out so delicious!!
For the Swirl:
Preheat oven to 350. Use a loaf pan and spray it with vegetable oil. In a mixer, or bowl using electric mixer, mix the bananas, butter, sugar, egg, and vanilla together. Add the dry ingredients just until mixed. Don't over mix.
Mix the sugar and cinnamon together for the swirl mix.
Then pour half of the bread mixture into the loaf pan. Sprinkle half of the swirl mixture over the bread mixture. Pour the remaining dough on top of the swirl mixture. Sprinkle the remaining mixture on the top of the bread mix.
Bake for 60-70 mins.
