How to Make Cinnamon Swirl Banana Bread

If you’ve admired bakery loaves with a perfect cinnamon swirl, you’ll be pleased to know it’s simpler than it looks. This recipe is nearly the same as a classic banana bread; the only difference is a thin, flavorful cinnamon-sugar ribbon layered in the center. With simple ingredients and a few easy steps, you’ll have a bakery-style loaf at home.

Ingredients You Need

Below are the ingredients for the loaf, organized by dry, wet, and the cinnamon swirl. Substitutions and notes are included where helpful.

  • White whole wheat flour — 1 1/2 cups. All-purpose flour can be used if preferred. This recipe has not been tested with gluten-free flour.
  • Brown sugar — 1/4 cup packed for the batter, and 1 tablespoon packed for the swirl. You can substitute coconut sugar if desired.
  • Baking soda — 1 teaspoon. Essential for lift and texture.
  • Salt — 1/8 teaspoon to balance the sweetness and enhance flavor.
  • Ripe bananas — about 3 medium (roughly 1 cup mashed). Very ripe bananas give the best flavor.
  • Large eggs — 2. Use large eggs for best results.
  • Maple syrup — 1/2 cup for natural sweetness and depth of flavor.
  • Greek yogurt — 1/4 cup. Works with the baking soda to make the loaf moist and tender.
  • Vanilla extract — 2 teaspoons for classic flavor.
  • Unsweetened almond milk — 1/4 cup to loosen the batter slightly. Dairy milk works too.
  • Melted butter — 3 tablespoons for the batter; an additional 2 tablespoons for the cinnamon swirl. Coconut oil can be used instead if preferred.
  • Ground cinnamon — 1 teaspoon for the swirl.

Fun Add-ins

For extra texture and flavor, consider stirring in one of the following into the batter before baking:

  • Chocolate chips
  • Raisins
  • Shredded coconut

How to Add a Swirl to Banana Bread

The cinnamon swirl is just three ingredients: melted butter, brown sugar, and cinnamon. It forms a thick, dark syrup that you layer between batters to create a clear ribbon of flavor.

Make the Cinnamon Swirl

Combine 2 tablespoons melted butter, 1 tablespoon packed brown sugar, and 1 teaspoon ground cinnamon in a small bowl. Stir until it becomes a smooth, syrupy paste.

Assemble the Loaf

Grease a standard loaf pan. Pour half the batter into the pan, then drizzle half of the cinnamon mixture over the batter. Use a knife or toothpick to gently swirl—don’t overmix; you want a defined ribbon.

Finish and Swirl Again

Pour the remaining batter over the first layer, spread evenly, then add the remaining cinnamon mixture and swirl lightly once more for a pretty finish. Be creative but gentle—light swirls keep the ribbon intact.

Step-by-Step Instructions

  1. Preheat the oven to 350°F (175°C). Spray a standard loaf pan with nonstick spray or line with parchment.
  2. Whisk the dry ingredients (flour, brown sugar for batter, baking soda, salt) in a medium bowl and set aside.
  3. In a large bowl, mash the bananas until mostly smooth. Add eggs and whisk until combined. Stir in maple syrup, Greek yogurt, vanilla, melted butter, and almond milk.
  4. Fold the dry ingredients into the wet ingredients until just combined using a wooden spoon. Avoid overmixing.
  5. Transfer half the batter to the prepared pan. Add and swirl half the cinnamon mixture. Top with the remaining batter, then add and swirl the remaining cinnamon mixture.
  6. Bake at 350°F for 25 minutes. Tent the loaf loosely with foil to prevent over-browning, then bake an additional 20–25 minutes, or until a toothpick inserted in the center comes out clean.
  7. Cool in the pan for 10–15 minutes, then transfer to a wire rack to cool completely before slicing.

Tips & Tricks

  • Use very ripe bananas for the best sweetness and banana flavor.
  • Don’t over-swirl; gentle motion keeps the cinnamon layer noticeable and pretty.
  • Tenting the loaf with foil after the initial bake prevents a thick, tough crust while the center finishes baking.
  • If using frozen bananas, thaw completely and drain any excess liquid before mashing and measuring.
  • Approximately three medium bananas yield about 1 cup of mashed banana.

Storage

Allow the loaf to cool completely. Store in an airtight container or wrapped in plastic on the counter for up to 3 days. For longer keeping, refrigerate for up to 5 days.

Freezer Instructions

  1. Cool the loaf completely. Wrap tightly in plastic wrap, then in foil to prevent freezer burn.
  2. Remove as much air as possible, label with the date, and freeze for up to 3 months.
  3. Thaw at room temperature or warm gently in a low oven to refresh the loaf.
