Thank you for choosing Huel. Awesome to see you on board. Sorry to hear you aren’t loving the Unflavoured, I am not a massive fan as it is a little earthy. The vanilla is epic and I very rarely even add flavour. Huel fills me up so much that on days where I have it for breakfast and lunch I have to make it sweeter to coerce my body into eating more!
I would say use milk on occasion. It tastes awesome, but it will disrupt the macro-nutrient proportions somewhat. Perhaps just as a treat a couple of times a week?
I would add half a teaspoon of cinnamon, shake, have a taste and add more if needed.
Instant coffee is really good. Just add a teaspoon or two and shake it with the Huel and water. For a really epic morning Huel then add some cold brew coffee, you only need a tiny bit because it is so strong!
Have a look at this page too for more flavouring ideas - How do you flavour your Huel?
Hope this helps you out!
