Oat and Buckwheat Gluten Free Banana Bread

There are a lot of -frees with this vegan gluten-free banana bread – gluten-free, dairy-free, egg-free, refined sugar-free – but it’s amazing. The first time I tested it I was genuinely blown away by how virtually identical the crumb and flavour were to my usual spelt flour banana bread.

A number of readers have made my tahini banana bread with buckwheat flour, so I thought it’d be a good starting point, but mixing with oat flour is what makes the texture fantastic. I’ve added chocolate chunks (obviously) but the mix-ins are flexible.

Even though I don’t have such a problem with gluten, I love baking with alternative whole grain flours and gluten-free options can be great. I don’t use gluten-free flour blends because I prefer whole grains and never really understand why someone would develop a gluten-free recipe that relies on readers using a very specific branded blend that might be unavailable or too expensive. This oat flour banana bread has become a go-to, despite using spelt as my base flour for just about everything otherwise.

Why You Should Try This Recipe

  • It’s a one-bowl recipe: as with most gluten-free recipes, there’s little worry about over-mixing and no need to use separate bowls. Less dishes needed.
  • No eggs needed: bananas are a natural binding agent so there’s no need for eggs or an egg replacer like flax, making for a super simple quick bread with a very light crumb.
  • It has a fantastic flavour: nutty buckwheat, peanut butter, and spices make for a more complex banana bread that’s great for an adult palate.

Ingredients You’ll Need and Why

It might seem like a lot of ingredients, but the only real difference when compared to a wheat flour banana bread recipe is that this one uses two flours and a little bit of arrowroot. These are my notes from testing and the full recipe card can be found below.

Banana bread ingredients with labels.
  • Bananas: for the best banana bread, you should always use overripe bananas that are visibly brown and spotty. Heating them in the oven or microwave doesn’t work (they look ripe, but don’t sweeten) so you have to wait until they actually ripen at room temperature.
  • Oat flour: pictured is store-bought ground oat flour. You can make it yourself simply by grinding rolls oats in a food processor until a very fine flour forms, or buy it. The loaf is a bit lighter and will hold together more effectively if the flour is very fine. Sift it if you’re making it yourself and it’s a bit gritty, but be sure to weigh the sifted amount to be accurate.
  • Buckwheat flour: I’ve only ever used whole grain buckwheat flour and haven’t tested this recipe with sifted buckwheat flour. I’m sure it would be fine and the only difference would be a slightly lighter bread, in both taste and texture.
  • Non-dairy milk: I use oat milk but any other refrigerated milk type will work (not canned coconut milk). In a pinch you can use water.
  • Peanut butter: for a nut-free option, use sunflower seed butter instead of peanut butter. Alternatively, tahini is a great seed based option – and if you just want to change the nuts up, any runnier nut butter will work well. Avoid the dry bottom-of-the-jar stuff.
  • Olive oil: the flavour isn’t really noticeable here, but feel free to use another light-tasting liquid oil. Melted and cooled coconut oil can be used but note that the bread will be denser when cooled.
  • Maple syrup: runny honey can be subbed if the recipe doesn’t need to be fully vegan. I haven’t tested with other liquid sweeteners or with granulated sugar.
  • Arrowroot: this improves the texture of the banana bread but can be omitted if you don’t mind a bit of crumbling. Substitute cornstarch in half the amount if preferred.

How to Make Vegan Gluten Free Banana Bread

It’s easy to do, but there are a couple of tips that will make for the best banana bread the first time you make it, like blending the banana mixture instead of mashing.

Banana bread steps 1 to 4.

Step 1: blend the bananas with the other liquid ingredients – this makes for the lightest texture – or mash the bananas with a fork and then mix in the other wet ingredients. I always use an immersion blender for this step.

Step 2: add the dry ingredients and stir to combine, then mix in the chocolate chips or chunks. You don’t need to worry much about over-mixing gluten free banana bread.

Step 3: transfer the batter to a lined loaf tin and optionally top with more chocolate (only do this if using baking chocolate, not a chopped chocolate bar, to avoid burning). The batter should be pretty runny.

Step 4: bake for about 50 minutes, or until a wooden skewer or toothpick inserted into the middle of the loaf comes out clean. Be sure to cool fully before slicing or the slices can crumble.

Expert Tips for the Best Banana Bread

  • Don’t make unlisted substitutions: while both gluten free, almond flour and coconut flour can’t be subbed 1:1 for oat or buckwheat flours as they absorb liquid at different rates.
  • Use weights if possible: if you have a kitchen scale, bring it out for this recipe. Gluten-free is a bit finicky, and although this recipe is pretty forgiving, you’ll still get the best results by weighing ingredients rather than using unreliable volume measurements.
  • Check oven temperature: if you’re following recipes precisely as written and still not getting perfect results, it might be a problem with your oven temperature. Many ovens run at incorrect temperatures and a portable oven thermometer will help.

Recipe Notes

The ripeness of the bananas contributes significantly to the sweetness and flavour of the loaf, so go for spotty, brown bananas. If you prefer less sweetness, then using slightly less ripe bananas is an easy way to reduce it.

I ground my own buckwheat flour for this recipe, which is pretty easy to do with a high-powered food processor or a grain mill, which I use. It has to be finely ground, though, so I would generally recommend buying buckwheat flour instead. Most grain mills aren’t appropriate for grinding oats into flour.

I recommend the immersion blender method because it makes for a very nice smooth batter and light crumb. If you prefer chunks of banana, go with the fork method.

My bread tin is a little longer and lower than standard (26×10.5 cm or just over 10 inches long) which means a slightly shorter cooking time. There are a number of variables, including true oven temperature, type and size of baking tin, any substitutions, using volume vs weight, etc. so doing a toothpick or skewer test is what’s going to ensure your banana bread is fully baked. I use a separate oven thermometer and recommend that if you do a lot of baking.

Walnuts, hazelnuts, mixed seeds, raisins, chopped dates, and so on, are all great additions here. Use them in place of or in addition to the chocolate, adding within reason. If you use way too much it’ll alter the structure of the loaf (I wouldn’t go over about ¾ cup total). You can also add a little shredded coconut if you like – here’s a coconut banana bread if you love that combination.

Description

An easy one-bowl vegan gluten free banana bread, made with a blend of whole grain oat and buckwheat flour. Lightly sweet and studded with chocolate chunks, it's a great go-to recipe!

Ingredients

  • 3 large ripe bananas about 250g / 9 oz. in total, weighed after peeling
  • 180 ml (¾ cup) oat milk or any unsweetened non-dairy milk
  • 100 grams (⅓ cup) natural peanut butter unsweetened and without added oil
  • 60 ml (¼ cup) olive oil or another light-tasting oil
  • 60 ml (¼ cup) maple syrup
  • 1 teaspoon pure vanilla extract
  • 125 grams (1 cup) oat flour
  • 120 grams (¾ cup) buckwheat flour
  • 2 tablespoons arrowroot flour or 1 tablespoon cornstarch
  • 2 teaspoons cinnamon
  • 2 teaspoons baking powder
  • ½ teaspoon baking soda
  • ½ teaspoon sea salt
  • ½ teaspoon nutmeg
  • 100 grams (½ cup) dark chocolate, chopped, or chocolate chips use baking chocolate for the best results

Instructions

  • Preheat the oven to 180°C (350°F) and line a bread tin with parchment paper.
  • Add the bananas, milk, peanut butter, olive oil, maple syrup, and vanilla to a large bowl. Use an immersion blender to mix until smooth. Alternatively, blend in a standing blender, or mash the bananas with a fork before whisking in the other wet ingredients.
    3 large ripe bananas, 180 ml (¾ cup) oat milk, 100 grams (⅓ cup) natural peanut butter, 60 ml (¼ cup) olive oil, 60 ml (¼ cup) maple syrup, 1 teaspoon pure vanilla extract
  • Add the oat flour, buckwheat flour, arrowroot, cinnamon, baking powder and soda, salt, and nutmeg to the bowl. Mix until well combined and no visible streaks of flour remain.
    125 grams (1 cup) oat flour, 120 grams (¾ cup) buckwheat flour, 2 tablespoons arrowroot flour, 2 teaspoons cinnamon, 2 teaspoons baking powder, ½ teaspoon baking soda, ½ teaspoon sea salt, ½ teaspoon nutmeg
  • Stir the chocolate into the banana bread batter, mixing until it's evenly incorporated throughout. Over-mixing isn't really a concern with gluten-free banana bread.
    100 grams (½ cup) dark chocolate, chopped, or chocolate chips
  • Pour the batter into the prepared baking tin, topping with additional chocolate if desired.
  • Bake for 45-50 minutes, or until a toothpick or skewer inserted into the middle of the loaf comes out clean. The top of the loaf should be golden in colour.
  • Cool the banana bread in the tin for ten minutes before removing and cooling fully on a rack. This keeps well for 3 to 4 days in a sealed container at room temperature and freezes well.

Notes

• Please note that the volume/weight for the flours is not incorrect – buckwheat flour is heavier and very finely ground, so it weighs more per cup. 
Cup measurements are provided as a courtesy and are not reliable or accurate. I highly recommend using a scale to properly measure your ingredients for a consistent outcome.
Storage: keep in a sealed container for 3-4 days at (cool) room temperature, or refrigerate to store longer.
Freezing: this freezes well as a full loaf or individual slices. Place in an airtight container and freeze for up to three months.

  1. Is the weight listed for the bananas per banana or for all the bananas? This loaf looks delightful and I love buckwheat
