I love a scoop of Vanilla mixed with a scoop of Mint Choc (it works especially well as the Mint Choc already has a base of Vanilla). Also you already have both of these so it’s easy to try. It just tastes of the Mint Choc so you can get through both bags that way.
I personally like the flavour.
But what I have been doing as i take my Huel for breakfast after the gym and feel 3 scoops isn’t enough to hold back my hunger until the afternoon I blend a banana in to it. Completely takes away the vanilla flavour and a great energy source too.
I found the vanilla to have sweet aftertaste but on adding cacao it was fine. I also mixed it with u/u or original both which moderated the sweetness but the aftertaste was still there.
