Step 1: Preheat Oven: Preheat the oven to 350F (175C). Grease and flour a 9x5 inch loaf pan. This step ensures the bread bakes evenly and doesn't stick to the pan.
Step 2: Combine Wet Ingredients: In a large bowl, mash the ripe bananas until smooth. Add the eggs and oil (or melted butter) and mix well to combine. Ensure the mixture is evenly blended to avoid lumps.
Step 3: Incorporate Cake Mix: Gradually add the yellow cake mix to the wet ingredients, mixing until just combined. Be careful not to overmix, as this can result in a tough bread. If using, gently fold in the cinnamon and nuts.
Step 4: Transfer to Pan: Pour the batter into the prepared loaf pan, spreading it evenly. This ensures that the bread bakes uniformly and has a level top.
Step 5: Bake: Bake in the preheated oven for 50-60 minutes, or until a wooden skewer inserted into the center comes out clean. Keep watch to avoid overbaking.
Step 6: Cool: Let the bread cool in the pan for 10 minutes before transferring it to a wire rack to cool completely. This prevents the bread from becoming soggy and allows it to retain its shape.
Optional Tips:
For a richer flavor, use melted unsalted butter instead of vegetable oil.
Add 1/4 cup of sour cream or yogurt for extra moisture.
If the top of the bread begins to brown too quickly, tent it with foil during the last 15 minutes of baking.
To make mini loaves, divide the batter among mini loaf pans and reduce the baking time accordingly.
