The snack I make when I want something sweet that is not dessert is this one – mashed banana, rolled oats, and chia seeds pressed into rough balls and baked for twenty minutes at 175 degrees. A home cook wrote it in five steps with the recipe’s whole promise in the title: healthy, filling, and super simple. I made it as written, and it is the snack I now keep in a sealed tin for the hours when the kitchen is closed but the stomach is not.
Qi ya zi xiang jiao yan mai qiu (奇亚籽香蕉燕麦球) is chia banana oat bites – mashed banana mixed with rolled oats and chia seeds until no dry oats remain, shaped into freehand balls, and baked at 175°C (347°F) for 20 minutes until golden. The original is a 5-step recipe with three ingredients and a note: the mixture can be slightly dry, which is fine.
What Are Chia Banana Oat Bites?
Chia banana oat bites are a three-ingredient snack: ripe banana mashed into a paste, rolled oats and chia seeds pressed in with a spatula until no dry oats remain, and the mixture shaped into freehand balls of any size onto a nonstick tray, then baked in a convection oven at 175°C (347°F) for 20 minutes, adjusted to your oven and your preferred browning. They are sweet only from the banana – no sugar is added – and the oats and chia make them genuinely filling.
The method is the appeal: no mixer, no weighing anxiety, no added sugar. The one textural rule is in the recipe’s note – the mixture should be not too wet, on the dry side is fine, because a wetter dough spreads and takes longer to firm. The balls come out with a rough, golden surface, crisp at the edges and chewy within, and the recipe’s closing instruction is honest: cool them, seal them, and they keep.
For another bake-and-keep sweet from the same shelf, my crispy sticky rice apple cakes are the fruitier sibling of these oat bites.

Why This Version Works
- Three ingredients, no sugar. Banana, oats, chia – the sweetness is the banana’s, and nothing else is invited.
- On the dry side is fine. The recipe’s note: not too wet, slightly dry is better – wet dough spreads and takes longer.
- Freehand balls, any size. The recipe’s portioning is deliberately relaxed – shape them as you like.
- 175°C for 20 minutes. The recipe’s timing, adjusted to your oven and your preferred browning – just do not burn them.
- Cool, seal, and keep. The recipe’s closing: cool completely and store sealed – the snack tin is the point.
Equipment Needed
- An oven (convection mode, the recipe’s 175°C / 347°F)
- A mixing bowl and spatula
- A nonstick baking tray
- A sealed tin for storage
Ingredients
- 2 ripe bananas, mashed
- Rolled oats, to bind (about 1 cup)
- Chia seeds, to taste (about 2 tbsp)
Ingredient Notes
Bananas: Two ripe bananas, mashed into a paste – the only sweetener. The riper, the sweeter. My broccoli carrot egg pancakes are the savory-snack counterpoint on the same baking shelf.
Rolled oats: About a cup, pressed in until no dry oats remain – the bulk and the chew. My crispy sticky rice apple cakes use a grain base the same way.
Chia seeds: To taste, about 2 tablespoons – the seeds’ gel helps bind and adds the healthy label’s worth. My smiling sesame cookie balls are the seeded, sugared cousins.
Prep & Mise en Place
Preheat the oven to 175°C (347°F) convection. Mash the bananas. Press the oats and chia into the mash with a spatula until no dry oats remain – not too wet, slightly dry is fine, the recipe’s rule.
The sequence: shape freehand balls onto the nonstick tray, bake 20 minutes, cool completely, and store sealed.
Cooking Process
Step 1 – Preheat the Oven
Preheat the oven to 175°C (347°F) in convection mode – the recipe’s temperature.
Step 2 – Press the Oats and Chia Into the Banana
Add the rolled oats and chia seeds to the mashed banana and press with a silicone spatula until no dry oats remain. The recipe’s textural note: do not make it too wet – on the dry side is better.
Step 3 – Shape the Freehand Balls
Shape the mixture into balls of any size you like and set them on the nonstick tray – the recipe’s portioning is deliberately relaxed.
The counterintuitive detail: the dough should be slightly DRY – and that dryness is what makes the bites hold their shape. A wetter dough spreads into flat discs and needs more oven time to firm; the slightly dry mixture stands up as rough balls, bakes with a crisp surface and a chewy center, and finishes in the recipe’s twenty minutes. The banana’s moisture is the binder – it does not need help.
Step 4 – Bake at 175°C for 20 Minutes
Bake in the convection oven at 175°C (347°F) for 20 minutes. Adjust the time to your own oven’s temperament and your preferred browning – the recipe’s only warning: do not burn them.
Step 5 – Cool, Seal, and Keep
Out of the oven, cool completely, and store sealed – the recipe’s final instruction. The snack tin is ready.
Common Mistakes When Making These Bites
1. Flat, spreading discs. Cause: a wet dough. Fix: press in more oats – the recipe’s slightly-dry rule.
2. A raw, doughy center. Cause: under-baking or giant balls. Fix: 20 minutes, and size the balls evenly.
3. Burnt edges. Cause: the oven too hot or too long. Fix: 175°C (347°F) and the recipe’s timing.
4. Bites that crumble. Cause: not enough banana or too many dry seeds. Fix: keep the banana’s moisture as the binder.
5. A bland, dry bite. Cause: under-ripe bananas. Fix: use ripe bananas – they are the only sweetener.
6. Sticky, stuck bites. Cause: no nonstick tray or hot removal. Fix: a nonstick tray and cool completely before lifting.
Variations
Add-ins: A handful of raisins, chocolate chips, or nuts with the oats.
Peanut butter: A spoon of peanut butter in the banana makes them richer – my crispy sticky rice apple cakes are the fruit-grain alternative.
Cinnamon: A pinch with the oats for warmth – and with yellow millet sticky rice cake and crispy pork floss and ham rolls, the snack tin is full.
The snack shelf: With smiling sesame cookie balls and Chinese date cake, the tin is full.
Frequently Asked Questions
Are these sweet? Sweet from the banana only – the recipe adds no sugar.
Do they need chia? They help bind and add texture; without them, add a little more oats.
Can I use quick oats? Yes – rolled or quick both work; the texture differs slightly.
How long do they keep? Sealed at room temperature, about a week – if they last.
Can I freeze them? Yes – freeze in the tin; they thaw quickly.
How to Serve
Serve from the tin as a snack – with crispy sticky rice apple cakes and broccoli carrot egg pancakes for a snack board, or with steam-baked milk chiffon cake for a sweeter moment.
Storage & Reheat
Store sealed at room temperature up to 1 week, or freeze up to a month. No reheating needed – they are a cold snack.

About the Author & Recipe Development
I am Lin, a professional Chinese chef and food writer with a decade in restaurant kitchens before turning to recipes. This xiachufang baker’s three-ingredient bite is my snack-tin staple, and the recipe’s confidence – the slightly-dry rule, the freehand sizing, the honest “do not burn them” – is why it works. I tested it as written. I have not tested the peanut-butter or raisin variations, so those are your experiments, not my claims.
