Hi there! This is actually my first post, so I thought it a good idea for it to be a useful one!
Definitely try cocoa powder - the one you find in the baking section. It's naturally bitter rather than sweet so will counter the sweetness of the vanilla. Ice and/or frozen fruit, because of the temperate, reduces the sweetness too.
Here are a couple recipes I like (I use a blender, so if you use the shaker they obviously won't work):
- Add a frozen banana to water, 3 scoops Huel, 1.5 teaspoons of instant coffee, 2 teaspoons of cocoa powder
- Add a small handful of frozen cherries (you can buy a pack from Tesco for £2) to 3 scoops of Huel and water, and 2 teaspoons of cocoa for a "black forest" type of flavour. The cherries are more on the sour side so they don't add to the sweetness much.
You obviously have to factor in the calories of the fruit if you add it (1 banana is about 90, maybe about 30 in the amount of cherries I use) and these recipes only work with a blender but something like a nutribullet is good as they're easy to clean up too.
