The image shows a banana–chia–oat drink made with almond milk, and the left glass illustrates the ingredients layered before blending. It can be made as a thick breakfast smoothie, an overnight oat-style drink, or a spoonable breakfast bowl.
Below is a complete recipe with measurements, nutrition, allergens, substitutions, storage, and Q&A.
Classic Banana Chia Oat Smoothie
Yield
1 large serving — approximately 450–500 ml
Preparation time
5 minutes
Optional soaking time
10–30 minutes
Ingredients
Ingredient Amount
Ripe banana 1 medium
Unsweetened almond milk 1 cup / 240 ml
Rolled oats ½ cup / about 40 g
Chia seeds 1½ tbsp / about 18 g
Cinnamon ¼ tsp
Vanilla extract ½ tsp
Ice ½–1 cup
Salt Tiny pinch
Optional
1–2 tsp honey or maple syrup
1 tbsp peanut butter
1 tbsp almond butter
½ tsp ground flaxseed
1–2 dates for extra sweetness
A few banana slices for topping
You normally don’t need extra sugar if the banana is very ripe.
Step-by-Step Recipe
1. Prepare the oats
For a smoother smoothie, place the oats and almond milk in the blender and allow them to sit for 5–10 minutes.
This softens the oats and produces a creamier texture.
For an especially smooth drink, soak them for 20–30 minutes.
2. Add the chia seeds
Add the chia seeds to the blender.
If you prefer a completely smooth drink, you can blend the chia seeds immediately.
If you like the tiny chia-seed texture shown in the photograph, don’t blend quite as long.
3. Add banana
Peel and add 1 ripe banana.
A banana with plenty of brown spots will give you significantly more natural sweetness.
4. Add flavoring
Add:
¼ tsp cinnamon
½ tsp vanilla
Tiny pinch of salt
The salt isn’t intended to make it salty—it simply enhances the banana and cinnamon flavors.
5. Blend
Blend on high for approximately 45–60 seconds.
Add ice and blend again until smooth.
For a thick smoothie:
Use less almond milk or more ice.
For a drinkable smoothie:
Add another ¼–½ cup almond milk.
No-Blender Version — Overnight Banana Chia Oats
You can make essentially the same recipe without blending.
Ingredients
½ cup rolled oats
1 tbsp chia seeds
¾ cup almond milk
1 banana
¼ tsp cinnamon
½ tsp vanilla
Pinch of salt
Method
Mash ½ banana.
Combine oats, chia seeds, almond milk, mashed banana, cinnamon, vanilla and salt.
Stir thoroughly.
Cover and refrigerate at least 4 hours, preferably overnight.
In the morning, add the remaining banana sliced on top.
Add a splash of almond milk if it has become too thick.
Layered Version Like the Photograph
If you want the presentation shown on the left side of the image:
Layer from bottom to top:
1. Rolled oats
Add approximately ⅓–½ cup.
2. Chia seeds
Add approximately 1½–2 tbsp.
3. Banana slices
Arrange several slices around the inside of the glass.
Then either:
pour the blended smoothie over everything, or
refrigerate the layered ingredients with almond milk for an overnight-oat version.
For a prettier presentation, reserve several banana slices and place them against the glass before pouring.

Important
The carbohydrates and calories are primarily coming from the banana and oats. The chia seeds contribute substantial fiber and healthy fats.
If you add honey, dates, peanut butter or almond butter, the nutrition will increase.
Nut & Allergen Information
Is chia a nut?
No.
Chia seeds are seeds, not tree nuts or peanuts.
Is almond milk a nut product?
Usually yes.
Almonds are tree nuts, so conventional almond milk is a tree-nut product.
Someone with an almond/tree-nut allergy should not assume almond milk is safe.
Nut-free version
Replace almond milk with:
oat milk
soy milk
coconut milk beverage
rice milk
another nut-free milk alternative
If this is for someone with a severe allergy, check the manufacturer’s allergen statement for cross-contact.
Is it gluten-free?
The individual ingredients can be gluten-free, but regular oats can be contaminated with wheat, barley or rye during processing.
For someone with celiac disease or significant gluten sensitivity, use certified gluten-free oats.
Is it dairy-free?
Yes, if you use dairy-free almond milk.
Is it vegan?
Yes, provided the almond milk and any optional sweetener are vegan.
Adding Nut Butter
For a more filling breakfast, add:
Peanut butter
1 tbsp
Adds approximately:
90–100 kcal
3–4 g protein
8 g fat
Almond butter
1 tbsp
Adds approximately:
95–100 kcal
3–4 g protein
9 g fat
This makes the smoothie considerably richer and more satiating.
Remember: peanut is a legume, while almond is a tree nut.
How to Make It Higher in Protein
The basic smoothie is relatively moderate in protein.
For a more substantial breakfast, choose one:
Option 1 — Greek yogurt
Add ½ cup plain Greek yogurt.
Option 2 — Soy milk
Replace almond milk with 1 cup unsweetened soy milk.
Option 3 — Nut butter
Add 1 tbsp peanut or almond butter.
Option 4 — Protein powder
Add ½–1 scoop of your preferred protein powder.
If using protein powder, you may need another ¼–½ cup almond milk because it thickens the smoothie.
How to Make It More Filling
For a very thick breakfast:
1 banana
½ cup oats
2 tbsp chia
1 cup almond milk
1 tbsp nut butter
cinnamon
vanilla
Blend thoroughly and let it sit for 5–10 minutes after blending.
The chia and oats will continue absorbing liquid, making it thicker.
Variations
Strawberry Banana
Add ½ cup strawberries.
Chocolate Banana
Add 1 tbsp unsweetened cocoa powder.
Apple Cinnamon
Replace half the banana with ½ small apple and increase cinnamon.
Banana Peanut Butter
Add 1 tbsp peanut butter and a pinch of cinnamon.
Banana Date
Add 1–2 pitted dates instead of honey.
Tropical
Use banana + mango + coconut milk beverage.
Frequently Asked Questions
Can I prepare this the night before?
Yes. Store it covered in the refrigerator and consume within about 24 hours for the best flavor and texture.
It may become considerably thicker because the chia and oats continue absorbing liquid.
Add a splash of almond milk and stir or blend again before drinking.
Can I use quick oats?
Yes. Quick oats produce a softer, smoother smoothie.
Rolled/old-fashioned oats give slightly more texture.
Can I use steel-cut oats?
Not raw in this recipe. They remain quite hard and can make the smoothie gritty.
Use cooked and cooled steel-cut oats instead.
Do I need to soak chia seeds?
No, but soaking them can improve the texture.
For a very smooth smoothie, blend them directly.
For an overnight version, let them hydrate in the liquid.
Why did my smoothie become extremely thick?
That’s usually the chia seeds and oats absorbing the liquid.
Add ¼ cup almond milk at a time until you reach the consistency you want.
Can I use frozen banana?
Yes—and it’s one of the best options.
Frozen banana makes the smoothie naturally cold, thick and creamy without requiring much ice.
Can I use two bananas?
Yes, but it will make the smoothie:
sweeter
higher in calories
higher in carbohydrates
You’ll probably also want to reduce the added sweetener.
Can I omit chia seeds?
Yes.
The smoothie will be thinner and have less fiber and healthy fat.
You could replace them with 1 tbsp ground flaxseed, although the texture will be different.
Can I omit oats?
Yes.
You’ll get a lighter banana-chia smoothie rather than a banana-oat breakfast smoothie.
Can I make it without almond milk?
Absolutely. Use oat, soy, rice or another milk alternative.
Can I use dairy milk?
Yes. Whole, low-fat or skim milk can all work.
This changes the nutritional profile and makes the recipe not dairy-free.
Is this suitable for weight loss?
It can fit into a weight-management diet, but portion size and total daily calorie intake matter.
The combination of oats, chia and banana provides fiber and carbohydrates, while adding yogurt, soy milk or nut butter can increase protein/fat and satiety.
It’s not inherently a “weight-loss” food.
Is this good before exercise?
It can work well as a pre-workout breakfast because it provides carbohydrates from banana and oats.
For exercise immediately after eating, consider making it smaller and using less chia/oats if you find high-fiber foods uncomfortable.
Can I give this to children?
The ingredients are ordinary foods for most children, but consider the child’s age, chewing ability and any allergies. Whole chia seeds should be appropriately prepared for young children rather than given dry.
How long does it keep?
For a prepared smoothie, refrigerate promptly and ideally consume within 24 hours.
Overnight oats generally keep about 2–3 days refrigerated, although banana can darken and the texture changes over time.
My Recommended Version
For the best combination of taste, texture and nutrition, I’d make:
1 ripe frozen banana
1 cup unsweetened almond milk
½ cup rolled oats
1½ tbsp chia seeds 1 tbsp peanut or almond butter
¼ tsp cinnamon
½ tsp vanilla
A handful of ice, if needed
Blend for 45–60 seconds, rest for 5 minutes, then add a little more almond milk if necessary.
