These easy Banana Baked Oats are a great gluten free breakfast meal prep idea, packed with protein and fibre and just like having dessert for brunch! You can bake a whole batch of these then portion them up to last the week – perfect if you’re often short of time midweek!

Notes On These Protein Banana Baked Oats
🍌 These easy Banana Baked Oats are great for meal prep as you bake them into bars and slice them up, a bit like cake for breakfast!
🍌 These Baked Oats are a bit like a cross between a gluten free flapjack and a squidgy dessert. They’re not sickly, but sweet enough to feel like a treat!
🍌 I make these using vegan protein powder and gluten free oats, making them completely gluten free, coeliac-safe and also vegan.
🍌 Once you’ve made this base recipe you can easily customise it – add cinnamon, dried fruits, white chocolate chips or different flavour protein powders.

Ingredients and Substitutions
There’s a printable recipe card below for these baked banana oats with the full quantities. But here are the main ingredients and ideas for any swaps:

- Bananas: The riper the bananas, the better. I like to use them when they have lots of black spots as they go super squishy and extra sweet.
- Gluten Free Oats: You can find these in the free from aisle. Normal oats are not safe for people with coeliac disease due to the cross contamination risk.
- Vegan Protein Powder: You can use any flavour, but I prefer something like vanilla or chocolate. Whey protein can be used but vegan protein (like pea or hemp) is much better for baking. This one is the one I have as it’s gluten free.
- Chocolate Chips: I use dark chocolate but you could use milk or white if you prefer. Make sure they are gluten free with no ‘may contain’ warnings.
- Vanilla Extract
- Almond Milk: I use this almond milk – you can swap for any milk (dairy free, or cow’s milk are both fine) but I use unsweetened almond milk to keep the calories lower.
- Baking Powder: Not all brands are gluten free so check my gluten free baking powder guide if you’re unsure.
- Maple Syrup: Or use honey if you prefer.
How to Make Banana Baked Oats
There’s a printable recipe card below with the method. But here are some step-by-step photos to show you how easy these banana baked oats are to make.





Storing and Freezing Instructions
TO STORE: Once baked, I find these keep well in the fridge for up to a week.
TO FREEZE: Freeze any leftovers (I do this in individual squares between sheets of baking paper) and defrost at room temperature when needed.
