This is one of my favourite smoothie recipes I make when I don’t want to cook any breakfast. It’s so filling, that I don’t need to have any snacks mid morning and keep going until mid day.

It combines my favourite flavours – coffee and banana.

Sometimes I swap the coffee for chocolate, if I don’t want the extra caffeine, but either way, the flavours work beautifully together.

Ingredients & Substitutions for Banana & Coffee Breakfast Smoothie with Peanut Butter

I’ve kept this recipe dairy and gluten free, because it’s what I have, but if you want to you can easily use any milk you have and swap around the oats for non-gluten type. It might change the flavour a little but that’s part of the fun!

If you want to make the smoothie less filling you can leave out the peanut butter or the oats or add more milk if you want to make it more like a drink than a meal.

Oats

I've used gluten free oats, but you can use any type of oats you have in your kitchen cupboard.

Milk

Any milk is fine, I've used dairy free, but normal milk works exactly the same.

Spice & Other flavouring

You can add a pinch of cinnamon or homemade mixed spice before you serve this smoothie, it's delicious!

I usually leave out any sugar, but if you like, you can add a bit of honey, agave syrup, teaspoon of brown sugar or any other sugar substitute you like.

I tend to use instant coffee for this recipe, but you could easily use a couple of tablespoons of fresh coffee, especially if you are used to grind your own coffee beans and make your coffee strong.

How to measure your oats

I've used about 1/4 cup of oates in this recipe, but if you want to you don't need to measure them.

This is because you can use an old fashioned method of measuring by hand. This is in fact a pretty sophisticated way of portion control and way of making sure your body has enough of fuel (= food) to keep going.

I'm sure you've already worked out that the actual measurement is different from person to person depending on what hand size you have.

A small child needs a lot less calories per meal than a grown adult and their hands match exactly the portions they should be getting. You can try it with any other ingredients, it works!

Preparing the oats for your smoothie

I like to soften the oats by boiling them first in the microwave or at least pouring hot water over them. This helps to make them more digestible. I know we are also blending our oats, but the boiling makes them to soak up water in advance.

You'll find that there is one extra step, which I always do when I'm using oats in my smoothies. I prepare the oats by leaving them to soak in boiling water.

Pouring boiling water over the oats (or cooking the oats in microwave or on a hob) speeds up the process and you don't need to pre-soak them overnight. Since we are going to blend the oats in the end anyway, I don't see any point keeping the oats structure.

How to make this smoothie extra filling

This Banana & Coffee Breakfast Smoothie with Peanut Butter is around 420 calories, if you add the ingredients in the quantities specified in my recipe. There is already plenty of fibre, protein and a good fat, which will provide you with a nicely balanced energy boost and it's a perfect amount of calories to replace a breakfast.

If you want to make the smoothie a bit more filling, you can for example add raw egg to your smoothie, which would add extra 75 calories (including extra fat & protein), tofu (for more protein) or flavour free oil, such as sunflower, rice, groundnut oil or even regular butter.

Storing & keeping your smoothie

My Banana & Coffee Breakfast Smoothie with Peanut Butter is best-used straightaway. This means making it and drinking it immediately.

However, if you want to keep your breakfast smoothie for a bit longer, it will be fine for a minimum of 12 hrs in the fridge.

This smoothie sometimes separates, when you leave it standing for longer. To bring your smoothie back together, stir it with a spoon or a fork before drinking it.

This smoothie also freezes well, providing you've not used previously frozen bananas. I find that making large batches and freezing my smoothies is actually pretty good way to save time in the morning.
