Banana and nut butter shake [no sweetener]

Banana nut butter shake in martini glasses.

This banana nut butter shake is healthy, quick, delicious and the best thing when you have a hankering for a healthy snack or are not hungry enough for a proper breakfast or lunch. Plus, it only needs 3 main common pantry/fridge ingredients (plus two flavourings, vanilla and cinnamon) and comes out super fluffy – yum, right?!

What’s in this banana nut butter shake?

Nut butter (whichever you have at home)

It’s not that long ago that I sang praises to nut butter (check out the nut butter fudge bites recipe, if you haven’t already – they’re heavenly) and here I am with another nut butter recipe. This one is super quick to make and the nut butter taste is not as prominent; that said, the nut butter lends a gorgeous depth of flavour to this milkshake which I enjoy very much.

Plus, nut butters (whichever kind you use) contain a number of important nutrients, including protein, healthy fats, fiber, vitamins and minerals and phytochemicals. I use the Kirkland mixed nut butter available from Costco which is made from almonds, cashews, pumpkin seeds, chia seeds and flax seeds (and I love the combo of nuts and seeds), but their almond butter is also AH-MAZING!

As I’ve mentioned previously, check the label and make sure your nut butter doesn’t contain any added sugar, oil or preservatives – try to stick with the natural ones which are 100% nuts.

I also encourage you to go for a different nut butter than peanut butter. I know that’s what we all probably have at home but not only will your gut microbiome benefit from different nut butters (it loves it when you eat lots of different healthy foods), live a little and try something new. Even if you have tried a natural nut butter before and didn’t like it, say, on toast (because it was too dry or too oily or you didn’t completely fancy the taste), using it in a shake like this is a perfect way to incorporate it in your diet and enjoy it (believe me)!

In addition to the nut butter, I have used two bananas here. I have written previously on the health benefits of bananas.

I have used ripe bananas at room temperature here but feel free to substitute frozen bananas if you like, for a thicker cooler shake (perfect for summer).

Plant based milk

The last main ingredient in this delicious banana nut butter shake is the milk. I have used almond milk and macadamia milk and both are delicious. You can use any other plant-based milk you like, or cow milk if that’s your preference.


Finally, a little shake of cinnamon (or speculaas, if you’re feeling fancy – that delicious spice mix is really super versatile) and vanilla paste will take this shake to another level.

I have said before (and will say it again, for sure) that these little beauties enhance the natural flavour of all sweet things and this shake is no different.

And what this shake does NOT have…

Is any added sweetener. That’s right, there is no sugar, maple syrup, honey, or anything else of the sort. There’s more than enough natural sweeteness coming out of the bananas and this shake doesn’t really need anything else. And that kind of makes me happy.
