This cinnamon banana loaf is soft, buttery, and swirled with cinnamon sugar for just the right amount of sweetness. It’s an easy way to use up overripe bananas, and the cracked, craggy top makes every slice feel extra cozy. You’re going to love it warm with coffee or toasted in a skillet with butter.
Why You’ll Love It
- Cinnamon sugar swirl — adds more flavor than plain banana bread without making it overly sweet.
- Uses simple pantry staples — no sour cream or specialty flour needed.
- Forgiving batter — uneven scoops and a cracked top are exactly what you want.
- Great warm or toasted — leftovers turn golden and buttery in a skillet.
Ingredient Notes
Use very ripe bananas—yellow with plenty of brown spots, soft enough that they practically collapse when you press them. Three medium bananas should give you about 1 1/2 cups mashed. If yours are gigantic, don’t go wild and add four just because they’re sitting there looking needy. Too much banana can make the loaf heavy and damp in the center, and then everybody stares at it like you committed a crime.
Unsalted butter is what I use, melted and cooled just a bit so it doesn’t start scrambling the eggs. I have used salted butter in a pinch and simply left the salt out once. It was fine. Not life-changing, but fine.
Light brown sugar makes the loaf taste a little warmer, a little deeper. Dark brown sugar would work if that is what you have, though it will make the flavor more molasses-y.
For cinnamon, use what you’ve got. I am not one of those people who can identify cinnamon varieties with my eyes closed. I buy the regular grocery-store kind in the red cap bottle, and nobody has ever complained. If they do, they can bake their own loaf.
Ingredients
- Butter or nonstick spray, for greasing a metal 9×5-inch loaf pan
- 3 medium very ripe bananas, mashed, about 1 1/2 cups; leave a few soft little lumps if you like
- 1/2 cup (1 stick) unsalted butter, melted and slightly cooled
- 3/4 cup granulated sugar
- 1/4 cup packed light brown sugar
- 2 large eggs, at room temperature if you remembered to set them out—I usually don’t
- 1 teaspoon vanilla extract
- 1 3/4 cups all-purpose flour
- 1 1/2 teaspoons ground cinnamon
- 1 teaspoon baking powder
- 1/2 teaspoon baking soda
- 1/2 teaspoon fine salt
- 2 tablespoons granulated sugar, for the cinnamon swirl topping
- 1 teaspoon ground cinnamon, for the cinnamon swirl topping
- 1 tablespoon melted butter, for the cinnamon swirl topping
Instructions
- Preheat the oven to 350°F. Grease a metal 9×5-inch loaf pan well with butter or nonstick spray, getting into those stubborn corners, then set the pan on a sturdy baking sheet. I used to skip the baking sheet because I thought it was unnecessary—then I tried lifting a full hot loaf pan out of the oven one-handed. Don’t be me.
- Mash the bananas in a large mixing bowl with a fork until mostly smooth, leaving a few small soft pieces. You are not making baby food here. Those banana bits make the finished loaf feel tender and homey, not like it came out of a plastic wrapper at the gas station.
- Pour the 1/2 cup melted, slightly cooled butter over the bananas and stir it together. Add the 3/4 cup granulated sugar and the 1/4 cup brown sugar, stirring until the mixture looks thick and glossy. It will not look elegant. It will look a little like mud at this point. Keep going.
- Beat in the eggs one at a time, stirring well after each one, then stir in the vanilla. The batter will be loose and lumpy, and that is normal. I know “normal” is a loaded word these days, but in banana bread terms, this is exactly right.
- In a separate bowl, whisk together the flour, 1 1/2 teaspoons cinnamon, baking powder, baking soda, and salt. Do not just dump all of this into the banana bowl without mixing, unless you enjoy finding one salty little pocket in a slice later. Ask me how I know. Actually, don’t.
- Add the dry ingredients to the wet banana mixture in two additions, stirring gently just until the flour disappears after each addition. A few streaks are not going to ruin your day. Overmixing, on the other hand, can make the loaf tougher, and nobody wants to chew banana bread like it is a work assignment.
- In a small bowl, stir together the 2 tablespoons granulated sugar, 1 teaspoon cinnamon, and 1 tablespoon melted butter for the topping. It should look like damp cinnamon-sugar sand.
- Spoon about half the banana batter into the prepared loaf pan in uneven scoops, letting it mound here and there. Sprinkle half of the cinnamon topping over that first layer. Don’t smooth it obsessively; the unevenness is part of the charm.
- Dollop the rest of the batter over the top, allowing some higher spots and lower spots, then sprinkle on the remaining cinnamon topping. Drag the tip of a butter knife through the batter in two or three loose lengthwise passes. Just enough to pull some cinnamon down inside while leaving the top pleasantly messy.
- Bake the loaf on its baking sheet for 55 to 65 minutes, until the top is deep golden and cracked and a toothpick inserted in the center comes out with a few moist crumbs but no wet batter. Start checking around 55 minutes, especially if your oven has moods. Mine claims 350°F but behaves more like it has personal grievances.
- Let the loaf cool in the pan on a wire rack for at least 15 to 20 minutes. The top may settle a bit—that’s fine. Run a knife around the edges, then carefully lift or tip it out of the pan. Serve warm for softer slices, or let it cool completely if you want neat slices. I rarely wait for neat slices.
Variations
For somebody who thinks cinnamon is “too spicy”—yes, I have heard that sentence in my own home—you can reduce the cinnamon in the batter to 1 teaspoon and skip the swirl topping altogether. A simple sprinkle of plain sugar over the batter before baking gives you a light crackly top instead.
If your family likes crunch, fold in 1/2 cup chopped walnuts or pecans along with the dry ingredients. I go back and forth. Walnuts feel more banana-bread-ish to me, but pecans are awfully good, so there you are.
You can swap half the melted butter for plain yogurt or sour cream if you want a slightly lighter loaf, though I will be honest: “lighter banana bread” is not usually what I wake up craving. Still, it stays moist and softens the sweetness a little. For dessert, drizzle a cooled loaf with a glaze made from 1/2 cup powdered sugar and 1 to 2 teaspoons milk.
I tried adding chocolate chips once because somebody in my family thinks every baked good needs chocolate. It was not bad, exactly, but it bulldozed right over the cinnamon and banana. A perfectly decent loaf, but not this loaf.
Storage & Reheating
Keep the loaf covered at room temperature for a couple of days. I usually wrap the cut end loosely and put the whole thing in a container, though it seldom lasts beyond the next afternoon. If your kitchen is warm or humid, refrigerate it after a day or two—but know that the fridge firms it up some.
For longer storage, wrap the cooled loaf tightly in plastic wrap and then foil, and freeze it. It thaws nicely on the counter. I have pulled one out for unexpected company, then remembered halfway through coffee that I had frozen it months earlier. Still good. Maybe better after a little thawing time, oddly enough.
To reheat a slice, toast it in a skillet with a tiny bit of butter over medium-low heat until the edges get golden. Microwave works, too, for about 10 to 15 seconds, but the skillet is worth the extra minute. Everything is worth it when butter is involved.
Final Notes
I still make this loaf with the messy spoonfuls and the lazy knife swirls. There are prettier banana breads out there, probably. Ones with perfect domes and artistic sliced bananas on top and a glaze that catches the light just so. Good for them.
This one looks like somebody made it at home because somebody needed something warm. Because the bananas were dying on the counter. Because the afternoon got too quiet, or too loud. Because the coffee was already brewing and a thick slice with butter sounded better than another handful of crackers over the sink.
That is plenty of reason, if you ask me.
