Creating your very own Homemade Cinnamon Swirl Banana Bread is easy when you follow these steps:

1. Preheat the Oven: Preheat your oven to 350°F (175°C). Grease a standard loaf pan.
2. Mash the Bananas: In a mixing bowl, mash the ripe bananas until smooth.
3. Mix in Butter: Add the melted butter into the mashed bananas and mix until combined.
4. Add Baking Soda and Salt: Stir in the baking soda and salt.
5. Blend in Sugar: Add the granulated sugar, followed by the beaten egg and vanilla extract, stirring until smooth.
6. Incorporate Flour: Gradually mix in the all-purpose flour until just combined. Be careful not to overmix.
7. Prepare Swirl Mixture: In a separate bowl, mix the brown sugar and cinnamon for the swirl.
8. Layer Batter: Pour half of the banana batter into the loaf pan, then sprinkle half of the cinnamon-sugar mixture over it.
9. Add More Batter: Pour the remaining batter on top, followed by the remaining cinnamon-sugar mixture.
10. Swirl Together: Using a knife or skewer, gently swirl the batter to create a marbled effect.
11. Bake: Place the pan in the oven and bake for 60 minutes, or until a toothpick inserted into the center comes out clean.
12. Cool: Once baked, allow the banana bread to cool in the pan for 10 minutes, then transfer it to a wire rack to cool completely.

Following these steps ensures your banana bread comes out gloriously moist and flavor-packed!
