This 5-Ingredient Flourless Banana Bread is an easy, naturally sweet loaf made with three very ripe bananas, eggs, smooth peanut butter or almond butter, baking soda, and cinnamon. It needs only 5 to 10 minutes of preparation before baking at 350°F (175°C) for 35 to 45 minutes, making it a practical small-batch bread for breakfast, snacks, or dessert.
The finished loaf is moist, tender, warmly spiced, and pleasantly nutty without needing wheat flour or added sugar. The bananas provide the sweetness and moisture, while the nut butter gives the bread satisfying richness and a soft, cake-like texture that firms beautifully as it cools.
Jump to RecipeWhy You’ll Love This Recipe
There is something especially appealing about a banana bread recipe that can be mixed in one bowl and does not require flour, sugar, or complicated equipment. This loaf keeps the ingredient list focused while still delivering the familiar comfort of classic banana bread.
Its texture lands between banana bread and a tender breakfast cake. The center stays moist from the ripe fruit and nut butter, while the edges become lightly golden and pleasantly chewy as they bake.
This is also an excellent recipe for using bananas that have gone well past their bright yellow stage. Heavily spotted or deeply brown bananas are ideal because their natural sweetness is more pronounced and their flesh mashes easily.
If you enjoy creative banana bakes, you may also like this cheesecake-style banana bread for a richer dessert-inspired variation.
- Simple preparation: Mash, whisk, stir, pour, and bake.
- Small yield: One loaf makes about 8 to 10 slices.
- Comforting flavor: Banana, cinnamon, and nut butter work naturally together.
- Flexible nut butter: Choose peanut butter or almond butter according to your taste.
Ingredients You’ll Need
The five ingredients each have an important job in this flourless loaf. Since there are no extra ingredients to hide behind, choosing ripe bananas and a smooth nut butter makes a noticeable difference.
- Three very ripe medium bananas: You need about 1 1/4 cups, or 375 grams peeled. Look for plenty of brown spots and soft fruit.
- Two large eggs: Eggs help bind the batter and support the loaf as it sets in the oven.
- One-half cup smooth peanut butter or almond butter: Use a creamy style for the most even batter and tender texture.
- One teaspoon baking soda: This provides the lift needed for the loaf to rise.
- One teaspoon ground cinnamon: Cinnamon brings gentle warmth and makes the banana flavor taste fuller.
For the best result, measure the bananas after peeling if you have a kitchen scale. Banana sizes vary, so the approximate 375-gram amount gives you a dependable balance of moisture for the small loaf pan.
Optional mix-ins such as chocolate chips, chopped nuts, vanilla, or salt appear in many variations, but they are not part of this basic five-ingredient formula. Keeping them out lets the banana and cinnamon remain the focus.
How to Make It Step-by-Step
Step 1: Heat the oven to 350°F (175°C), then prepare a small 8 1/2 x 4 1/2-inch loaf pan. Grease it well or line it with parchment, allowing the paper to extend over two sides so the loaf can be lifted out after cooling.
Step 2: Peel the bananas and place them in a large mixing bowl. Mash them with a fork until mostly smooth, leaving only a few tiny pieces if you enjoy visible bursts of banana in the finished bread.
Step 3: Add the two eggs and one-half cup of smooth peanut butter or almond butter. Whisk until the mixture looks cohesive, with no large streaks of egg or clumps of nut butter remaining.
Step 4: Sprinkle the baking soda and cinnamon over the banana mixture. Stir gently and stop as soon as the dry ingredients disappear; overmixing is unnecessary and can make the crumb less tender.
Step 5: Pour the batter into the prepared loaf pan and smooth the surface with the back of a spoon. Place the pan in the center of the heated oven and bake for 35 to 45 minutes.
Step 6: Begin checking the loaf around the 35-minute mark. It is ready when the center looks set and a toothpick inserted into the middle comes out clean or with a few moist crumbs rather than wet batter.
Step 7: Let the loaf cool in the pan for about 10 minutes, then transfer it to a wire rack. Wait at least 15 to 20 minutes before slicing, or cool it completely for the neatest pieces and firmest texture.

Pro Tips for a Tender Loaf
The bananas are the main source of both sweetness and moisture, so do not substitute firm, pale yellow fruit if you can avoid it. Bananas with abundant brown spots mash more smoothly and give the bread a deeper flavor without added sugar.
Use smooth, well-stirred peanut butter or almond butter. If the nut butter is very stiff, stir it thoroughly in its jar before measuring so the batter receives an even distribution of oils and solids.
Do not judge doneness by the top alone. Flourless banana bread can look baked on the surface while the middle still needs time, so test the center with a toothpick and look for a set crumb with a few moist crumbs.
If the top becomes deeply golden before the center is ready, tent the pan loosely with foil during the final 10 minutes. Do not press the foil onto the batter; simply lay it over the pan to slow browning.
Cooling is part of baking this recipe. The loaf continues to settle as it cools, and cutting too soon can make the center seem softer or more fragile than it truly is.
Serving Suggestions
Serve a slice slightly warm, at room temperature, or chilled. The flavor is delicious on its own, but a thin spread of peanut butter or almond butter makes the nutty notes even more noticeable.
For breakfast, pair the bread with coffee, tea, or fresh fruit. For an afternoon snack, cut the slices a little thicker and serve them with a glass of milk or a warm drink.
This loaf is also a lovely base for a simple dessert plate. A slice can be served beside yogurt or fruit, while a more elaborate banana dessert such as coconut banana cream pie is a wonderful choice when you are feeding a crowd.
Because the loaf makes approximately 8 to 10 slices, it works well for a small household. You can slice it as needed rather than turning a large batch into leftovers.
Storage and Reheating
Allow the banana bread to cool fully before storing it. Place it in an airtight container or wrap it well, then keep it at room temperature for short-term serving or refrigerate it when you want to hold it longer.
To enjoy a chilled slice, let it sit at room temperature briefly or warm it gently until just softened. Avoid overheating, which can dry the tender crumb and make the nut butter taste heavier.
For clean slices, use a sharp knife and wipe the blade between cuts. This is especially helpful if the loaf is still slightly moist in the center or if you are serving it as part of a dessert spread.

Troubleshooting Common Problems
Why did my loaf sink? The center may have needed more baking time, or the batter may have been mixed more than necessary. Always test the center before removing the pan, and stir only until the baking soda and cinnamon are incorporated.
Why is the middle very wet? Banana sizes and moisture levels vary, and a very full measure of mashed fruit can lengthen baking time. Continue baking until the center is set, tenting the top loosely with foil if it is already brown.
Why is my bread not very sweet? The sweetness comes from the bananas, so fruit that is only lightly spotted will produce a milder loaf. Choose heavily spotted, very ripe bananas for the most naturally sweet result.
Why did the slices crumble? The loaf may have been cut while hot. Let it cool in the pan for about 10 minutes, transfer it to a rack, and wait at least another 15 to 20 minutes before slicing.

Ingredients
Method
- Heat the oven to 350°F (175°C). Grease or line a small 8 1/2 x 4 1/2-inch loaf pan with parchment, leaving a little overhang to make the baked loaf easy to lift out.
- Mash the very ripe bananas in a mixing bowl until mostly smooth. A few small soft pieces are fine and will add little pockets of banana flavor.
- Whisk the eggs and smooth peanut butter or almond butter into the mashed bananas until the mixture is evenly combined and creamy.
- Stir in the baking soda and cinnamon just until incorporated. Avoid overmixing so the loaf keeps a tender texture.
- Pour the batter into the prepared pan and bake for 35 to 45 minutes, or until the center is set and a toothpick comes out clean or with a few moist crumbs.
- Cool the loaf in the pan for about 10 minutes, then transfer it to a rack. Let it cool for at least another 15 to 20 minutes before slicing, since the crumb firms as it cools.
