Coconut banana kombucha overnight oats [refined sugar free]

Overnight oats in a bowl.

These banana coconut kombucha overnight oats are a variation of my most favourite overnight oat recipe of all times and the product of a happy coincidence.

Last Thursday night, as I was getting ready to mix up my overnight oats, I went to reach for the apple and whaddaya know, they were all gone.

With the sort of hankering I was having for delicious overnight oats, I wasn’t about to give up. I looked around the fruit basket and in the fridge to see what I had on hand to replace the apple with. No pears, unfortunately, and berries would give the oats a very different texture. Gah! Luckily, just then my eyes fell on the bananas and these banana coconut kombucha oats were born.

Welcome to the kombucha overnight oats family

I initially thought I would mash the bananas with a fork (i.e. the lazy way) but getting the mashed bananas nice and runny would take time and a bit of effort and, honestly, at 9pm towards the end of a working week I just didn’t have the energy.

So I got my Nutribullet out and gave the bananas a quick blitz. That made them lovely and smooth and a little runny – perfect for mixing into the rest of the oatmeal mixture.

The rest of the ingredients are pretty easy and once it’s all mixed up, you do what the name say (duh!): pop it in the fridge overnight and the next morning (when you jump out of your bed thinking about this deliciousness), you’ll have this: perfectly smooth overnight oats with a lovely hint of banana flavour, refined sugar free but mildly sweet, with some nutritious chia seeds, gut friendly kombucha and yoghurt and a whiff of coconut, which are ready to be topped with your favourite fruit or seeds.

What are you eating?

I have done a detailed post on the ingredients in my kombucha overnight oats here – check it out. Most of the ingredients in the base recipe are the same.

In addition, this coconut banana version of kombucha overnight oats includes:

  • bananas = they are rich in potassium and fiber. They may help prevent asthma, cancer, high blood pressure, diabetes, cardiovascular disease, and digestive problems.
  • desiccated coconut = which is rich in both manganese and copper, and has also been proven to lower the risk of diabetes.
  • chia seeds = are an excellent source of omega-3 fatty acids, rich in antioxidants, and they provide fiber, iron, and calcium.
  • vanilla bean paste = which is a source of magnesium, potassium, calcium and manganese.

All in all, this is a wonderful gut friendly meal, with no refined sugar added, which should keep you feeling full, energetic and happy until lunchtime!

Versatility of overnight kombucha oats

What I love about this recipe is that you can LOVE the flavour, like I do, but always have a slightly different breakfast. Just top it with different fruits or seeds (if you like a bit of crunch), or stir in pink pitaya dragonfruit powder (I use this one from The Source Bulk Foods) or cacao powder (both shown in the photo above). By the way, if you like goji berries as plump as shown here, just put them in a cup, cover with cool water and leave them soaking overnight. When you’re ready for your breakfast, they will be ready too, looking all plump and beautiful.

You could also make this in half portions for kids or for some on the run goodness – it’s such fun to serve them in individual portions! Our five year olds LOVE this version of overnight oats and eat them straight out of the jam jars in which I make them (shown below) – I top them with fruit the night before or in the morning.

How is this recipe different from the original kombucha overnight oats?

The original recipe which is honestly FABULOUS (and I cannot tell you how many times I have eaten it in the last six months since I’ve first tried it) mixes in seeds and flaked nuts in the morning and so has a bit of texture to it. It also uses dried fruit, which this one doesn’t.

The banana coconut overnight oats on the other hand have a very smooth texture which is super creamy and light, and all around delicious. They include some chia seeds for an added shot of omega-3 fatty acids but the amount used is fairly small so that the texture of the chia seeds does not interfere with the smoothness of the oats.
