Notes

• Check banana ripeness by ensuring they’re very dark brown and soft, which guarantees maximum sweetness and moisture in the bread.
• Swirl gently when combining batters to create beautiful marbling – too much stirring will blend colors completely and lose the stunning visual effect.
• Use room temperature ingredients like eggs and butter to help them incorporate more smoothly and create a more consistent texture.
• Avoid overmixing the batter, which can make your bread tough – stir just until ingredients are combined for a tender crumb.
