This cinnamon roll banana bread is part banana bread and part cinnamon roll with cinnamon sugar swirled throughout the middle and topped with a cream cheese frosting!
Preheat the oven to 325°F. Spray a 9x5-inch loaf pan with nonstick cooking spray or line with parchment paper.
In a large bowl, cream butter and sugar with an electric mixer. Mix in the eggs, sour cream, and vanilla.
Stir in the flour, baking soda, salt and ground cinnamon just until combined. Fold in the mashed banana.
For the cinnamon swirl, mix together the sugar and cinnamon in a bowl.
Pour HALF of the batter into the loaf pan. Sprinkle cinnamon swirl mixture evenly over the top of the batter. Then top with remaining batter. Gently swirl down the center of the batter with a knife 1 time.
Bake 65-70 minutes, or until a toothpick inserted into the center comes out clean and the top is lightly browned. If the top is browning too fast, cover lightly with foil.
Remove from oven and let cool 10 minutes. Remove from the pan and place on a cooling rack.
Frosting
In a small bowl combine the melted butter, softened cream cheese and powdered sugar. Whisk until combined. Add a Tablespoon of milk if needed to thin. Then spread over top of the cinnamon roll banana bread.

This recipe will also fill 4 small loaf pans (make sure to decrease the baking time to about 35 to 45 minutes).Topping. Add a crumble topping to take the bread up a notch and add an extra sweet flavor.Healthier swaps.
