Protein Frosting for Protein Bars

If you are making protein bars and want added protein and some sweetness, you can make this protein frosting. It is actually like a frosting on cakes but only a little healthier. You can also use this frosting as a delicious smoothie ingredient, just add soy milk (or any milk you prefer) and a ripe banana.

Protein Frosting for Protein Bars

For 10 protein bars


  • 40 grams (1½ oz) soy protein (or whey protein)
  • 2 teaspoons carob powder or cocoa powder
  • 3-4 tablespoons pure maple syrup


  1. In a small bowl, mix the 40 grams soy protein, 2 tablespoons cocoa powder and 2-3 tablespoons maple syrup. The mixture should resemble a very thick chocolate sauce (not too runny and not too dry).
  2. Spread 1-2 teaspoons frosting on each power bar, arrange on a large dish and allow to harden completely in the fridge. This usually takes a couple of days.
  3. Wrap each bar into cling film and place in the fridge.
  4. Keeps for several weeks.


  • I prefer to use maple syrup as it becomes quite hard over time (unlike the agave nectar or honey).
  • You can use any protein you prefer. Some are vegan and other are non-vegan. Pea protein, soy protein and whey protein are popular and available in most health food stores.
