Frequently Asked Questions
Can I use quick oats instead of rolled oats?
Yes, you can. Quick oats are more processed and will break down faster in the blender, resulting in a slightly finer batter. The bread may be a little less chewy and slightly more dense, but it will still work. Do not use steel-cut oats, as they won’t soften enough and will make the bread gritty and hard.
Is this bread really sugar-free?
Yes, there is no added sugar—no granulated sugar, honey, maple syrup, or artificial sweeteners. The only sweetness comes from the ripe bananas themselves. Bananas contain natural sugars (fructose, glucose, and sucrose), so the bread does have naturally occurring sugar, but it’s entirely from whole fruit. If you prefer a sweeter loaf, you can add 1–2 tablespoons of honey or maple syrup to the batter, though it’s not necessary with very ripe bananas.
Can I make this vegan?
Yes, substitute the 2 eggs with flax eggs. Mix 2 tablespoons of ground flaxseed with 5 tablespoons of water, let it sit for 5–10 minutes until it becomes gelatinous, and add it to the blender with the other ingredients. The texture will be slightly denser and a bit more crumbly, but still delicious. Make sure your plant milk is also dairy-free (which it already is in the recipe).
What if I don’t have a blender?
You can make this bread without a blender by using oat flour instead of whole oats. Simply replace the 2 cups of rolled oats with 2 cups of store-bought or homemade oat flour (grind rolled oats in a food processor ahead of time). Mash the bananas very well with a fork, then whisk in the eggs, plant milk, oat flour, baking powder, salt, and cinnamon until you have a smooth batter. The texture will be identical.
Why did my bread sink in the middle?
This can happen if the bread was underbaked, or if too much liquid was added. Make sure to bake until a toothpick comes out clean, and don’t open the oven door too early in the baking process. Because there’s no flour to provide a strong gluten structure, the bread relies on the eggs and oat starch to set; if it’s not fully baked, the center can collapse as it cools. Also, ensure your baking powder is fresh.

Prep Time:
10 minutes
Cook Time:
35–42 minutes
Cool Time:
1 hour
Total Time:
About 1 hour 50 minutes
Yield:
1 loaf (about 10 slices)
Ingredients
- 2 very ripe medium bananas, peeled
- 2 cups rolled oats (certified gluten-free if needed)
- 2 large eggs
- ¼ cup unsweetened plant milk (almond, soy, or oat milk)
- 1 teaspoon baking powder
- Pinch of salt
- 1 teaspoon ground cinnamon (optional)
- Optional mix-ins: ½ cup chopped walnuts, ⅓ cup dark chocolate chips, ½ cup blueberries, etc.
Instructions
- Preheat oven to 350°F (175°C). Grease or line an 8½x4½-inch loaf pan with parchment paper.
- In a blender or food processor, combine the bananas, rolled oats, eggs, plant milk, baking powder, salt, and cinnamon. Blend on high until completely smooth, about 30–60 seconds.
- If adding mix-ins, fold them into the batter by hand after blending.
- Pour the batter into the prepared loaf pan and smooth the top. Optionally, sprinkle a few extra oats or a pinch of cinnamon on top.
- Bake for 35–42 minutes, until the top is golden and a toothpick inserted in the center comes out clean.
- Cool in the pan for 10 minutes, then transfer to a wire rack to cool completely before slicing. Slice with a serrated knife for clean cuts.
Notes
- Use very ripe, spotted bananas for the best natural sweetness. If bananas are not ripe enough, the bread will be less sweet and less flavorful.
- For a vegan version, replace the eggs with flax eggs: 2 tablespoons ground flaxseed + 5 tablespoons water, mixed and allowed to thicken for 5–10 minutes.
- Store in an airtight container in the refrigerator for up to 5 days, or freeze slices for up to 3 months.
- This bread is naturally gluten-free if you use certified gluten-free rolled oats. Always check labels.
