Prep and bake
- Preheat oven to 350°F and grease a 9x5 loaf pan, leaving no dry spots on the sides for clean release.
- Mix mashed ripe bananas, melted butter, sugar, large eggs, and vanilla extract until the batter looks glossy and uniform.
- Fold in all-purpose flour, baking soda, and salt just until no dry streaks remain, keeping the batter thick.
- Mix cinnamon swirl butter, brown sugar, and cinnamon separately until it forms a smooth, spreadable mixture with visible cinnamon specks.
- Pour half the banana bread batter into the loaf pan, then drizzle half the cinnamon mixture across the top in an even ribbon.
- Add the remaining banana bread batter, then swirl the remaining cinnamon through with a knife to create a marbled streak pattern.
- Bake for 55–65 minutes at 350°F until a toothpick comes out clean and the top is golden with set edges.
Finish with drizzle
- Let the loaf cool completely so the drizzle stays glossy instead of melting off.
- Beat cream cheese drizzle cream cheese, powdered sugar, and milk until smooth, then pour over the cooled bread so it coats the top in a thin layer.
Notes
For the cleanest swirl, drizzle the cinnamon mixture in a ribbon before the final batter addition, then swirl lightly with a knife—overmixing can turn the loaf uniformly brown. Store covered at room temperature for up to 3 days or refrigerate for up to 5 days; freeze slices for up to 2 months. For a dairy-reduced option, use plant-based butter and cream cheese alternatives in the same amounts.
