A versatile peanut butter and banana kefir smoothie. Add cocoa or coffee beans for different variations but the smoothie is lovely just as it is.

This is my favourite smoothie. It’s made from banana, peanut butter, ice and kefir but I nearly always bolster it with chia seeds, psyllium husk and a few dates if my banana isn’t ripe enough. The extra ingredients are optional but if you have them then add them for a fibre boost.

I sometimes add a tablespoon of unsweetened cocoa powder if I fancy a chocolate flavoured smoothie and a teaspoon of ground coffee beans is a great addition if you’re in need of caffeine.


Yoghurt is a good substitute if you don’t have kefir.
