Salted Caramel Honeycomb Quest Protein Bar

Quest bars were the original of the famous protein bars using isomalto-oligosaccharides or IMO syrup, probably more commonly known as VitaFiber. Now, there’s a whole host of different bars from various brands, all pretty similar in ingredients using either IMO or another prebiotic fibre such as Soluble Gluco Fibre.


IMO can now easily be bought on its own as an ingredient. That means homemade Quest bars can be yours for a fraction of the price. I’d tried using the VitaFiber syrup before, but never the VitaFiber powder. So, me being me, I got my hands on some and had a good play around with it trying to get a bar that didn’t stay sticky, but had enough moisture to bind it all together. I probably played a bit too much which is why it’s taken me so long. But oh well. Done now, and here you go:

Salted Caramel & Honeycomb Crunch ‘Quest’ Bar:

  • 15g VitaFiber powder
  • 10g vanilla whey
  • 2-3g (1tsp) casein (preferably unflavoured or vanilla)
  • 3g peanut butter (I used Bulk Powders)
  • 5ml (1 tsp) sugar free caramel syrup
  • 1 salted caramel Cadbury’s chocolate finger


  1. To a small bowl, add the syrup (if you have none, you may replace with 5ml of water but the flavour won’t be the same). Stir in the VitaFiber to form a thick paste.
  2. Stir in the whey protein and mix together.
  3. Add the casein protein, mix (or more like squish) together.
  4. Add the peanut butter and mix/squish again.
  5. Add the chopped up chocolate finger. Bring together into a ball and shape into a bar shape.

    Is it ok to sub extra whey in place of the casein, do you think? Thanks 🙂

      Unfortunately I found that it needs to casein to get a better texture! It ends up a bit too sticky otherwise. You could try using coconut flour or almond flour in place of it though, or add a bit more nut butter maybe? Just play with it until the texture is right for you 🙂
