I’d prefer to look for one that doesn‘t contain ‘synthetic flavour’. Better for you and likely fewer carbs. Lidl do a good and cheap one which is about 8g carb / 100g.
Oh, that's interesting ... I usually stay away from these types of cocoa powders. I use the ones with 100% cocoa, no sugar or other additives. I use it with milk, add a little agave syrup and cinnamon and it tastes amazing. I've been using Navitas recently (the little bag goes a long way). I don't know why I cant link to it here, it tells me my content is spammy ... but you can find it at iHerb or Wholefoods.
