Ingredients You’ll Need for Banana Blueberry Oat Muffins

Rolled oats – You can use whole oats and blitz them into flour, or use pre-ground oat flour.
Buckwheat flour – Naturally gluten-free and gives a soft texture with a slightly nutty taste.
Bananas – The riper the better! They add moisture and natural sweetness.
Eggs – To help bind the muffins and add protein.
Honey – A natural sweetener that pairs beautifully with banana.
Melted butter – For richness. You can substitute coconut oil for a dairy-free version.
Blueberries – I use frozen for convenience, but fresh will work too.
Cornflour – Tossing the berries in cornflour helps stop them sinking.
Cinnamon & vanilla – For that warm, cosy flavour.
Baking powder & salt – The basics to get a good rise and balance the sweetness.

How to Make These Muffins

These Banana Blueberry Oat Muffins come together in just a few simple steps.

Ingredients needed to make healthy banana blueberry oat muffins.

Preheat your oven to 160°C (fan-forced) and line a 12-cup muffin tin.
Make oat flour by blitzing your rolled oats in a food processor or blender.
In a large bowl, combine oat flour, buckwheat flour, baking powder, cinnamon and a pinch of salt.
In a separate bowl, mash the bananas (it’s fine to leave some small lumps). Whisk in the eggs, honey, melted butter and vanilla.
Stir wet into dry ingredients until a thick, smooth batter forms.
Toss your blueberries in cornflour, then fold them into the batter.
Divide the mixture evenly into the muffin tray and bake for 25 minutes, until golden and just firm to touch.
Cool on a rack before storing or serving.

Recipe FAQs

Can I use fresh blueberries instead of frozen?
Yes, fresh blueberries work just as well. You may not need the cornflour, but a light toss still helps prevent sinking.

What can I use instead of buckwheat flour?
You could try plain wholemeal flour or a gluten-free blend. Keep in mind this might slightly change the texture.

Are these muffins suitable for toddlers?
Yes! They’re sweetened only with fruit and honey. If serving to children under one, swap honey for maple syrup.
