I must admit I am a bit of a banana oat smoothie addict. There was a time when I would have it daily for over two months, that's how much I liked this breakfast that's ready in five minutes but packs a nutritional punch.
One day, I decided to add some flavor to the already delicious smoothie I used to make with bananas, oats, and oat milk.
So I added some peanut butter for that extra protein and a tablespoon of chia seeds for a bit more fibre and omega-3 fatty acids, not to mention the antioxidants.
What ingredients go into the banana oats chia seeds smoothie?
You'll need the following ingredients to make this banana oat smoothie with peanut butter and chia seeds.
- Bananas - a medium-sized one would do, approximately 120 grams. You can use fresh or frozen bananas. I personally like the frozen ones in the summer, but for the winter season, I like to go with a very ripe fresh banana.
- Some good old fashioned porridge oats, the rolled kind. My favourite is the organic variety you can find at Holland and Barrets in the UK, but just any kind of porridge-style oats would work a treat.
- Oat milk - I have tried to make this smoothie with unsweetened almond milk, and it tastes great, but the oat milk really brings the whole thing together better. Oatly is the best I could find in the UK, but Alpro would do, too.
- Peanut butter - now, being the experimental sort of girl that I am, I must have legit made this smoothie with almost all the peanut butter types I could find in the UK. Two that I like best are Meridian Smooth Peanut Butter, which tastes great and isn't made with palm oil, and the Whole Earth Smooth Peanut Butter, which is also palm oil-free and also organic. You can use crunchy peanut butter as well, but you might be left with some crunch in the smoothie, particularly if your blender is not very powerful.
- Chia seeds - a tablespoon of chia seeds provide fiber, iron, and calcium, while also being full of antioxidants and omega-3 fatty acids. It's the boost your smoothie didn't know it needed.
