This moist Banana Cinnamon Swirl Bread is an easy quick bread recipe packed with banana flavor and a sweet cinnamon swirl—perfect for breakfast, snacks, or gifting!
Preheat oven to 350℉. Mix together cinnamon with ⅓ cup sugar. Butter 4 mini loaf pans or a 9-by-5-by-3-inch loaf pan; set aside.
In an electric mixer fitted with the paddle attachment, cream butter and sugar until light and fluffy. Add eggs, and beat to incorporate.
In a medium bowl, whisk together flour, baking soda, and salt. Add to the butter mixture, and mix until just combined. Add bananas, sour cream, and vanilla; mix to combine.
Layer half the batter into prepared pan. *(If using 6 inch loaf pans use about 2-2 ½ large scoops (large scoops are about 4 Tablespoons) Smooth this layer out. Then sprinkle on half of the cinnamon sugar *(or about 2-3 Tablespoons if using 6 in pans) Using a knife or fork gently stir the cinnamon sugar just until even and smoothed out. Layer on next layer of batter. Top with remaining sugar mixture.
Bake until a cake tester inserted into the center of the bread comes out clean, about 1 hour 10 minutes. Let rest in pan for 10 minutes, then turn out onto a rack to cool. *6 inch loaves bake about 25-30 minutes.
Notes
I personally prefer this bread in the mini loaf pans. It stays more moist this way and the perfect size to snack on. Be sure and read the recipe carefully so that you prepare it correctly.
