Method
Prepare the loaf pan and swirl
- Preheat oven to 350F, then grease a 9x5 loaf pan so the bread releases cleanly.
- Stir together the cinnamon roll swirl ingredients into a smooth paste, making sure the brown sugar is evenly distributed.
Mix the banana bread batter
- Beat the softened butter and granulated sugar until fluffy, then beat in the eggs one at a time.
- Add the mashed bananas, sour cream, and vanilla, mixing just until smooth.
- Fold in the all-purpose flour, baking soda, salt, and cinnamon until no dry streaks remain.
Assemble and bake
- Pour half the batter into the greased loaf pan and spread it into an even layer.
- Spread the cinnamon swirl paste over the batter, leaving a thin border so it doesn’t spill.
- Top with the remaining batter and gently smooth the surface.
- Swirl through the batter with a knife to create marbled cinnamon ribbons through the loaf.
- Bake at 350F for 60-65 minutes, until a toothpick inserted in the center comes out clean.
Glaze and serve
- Drizzle the cream cheese glaze over the warm loaf so it melts slightly and sets as a glossy finish.
Notes
For the best swirl, spread the cinnamon paste quickly while it’s soft, and don’t over-mix the batter after adding flour. Store covered at room temperature up to 3 days or refrigerate up to 5 days; freeze slices up to 2 months. For a lighter option, swap half the butter for an equal amount of neutral oil (texture will be a touch softer).
