I don't have a recipe for a bar, but I got a recipe for an AWESOME spirulina truffle.

1 tbsp coconut oil
1 tbsp sweetener - yacon, agave, or raw honey
1 heaping tbsp spirulina
about a teaspoon ginger powder

First mix the oil and yacon/agave/honey. . . then add the spirulina and ginger. mix together, form into a truffle shape, and put in the freezer for 15 minutes, or in the fridge for longer. perfect fudge texture, delicious taste! and it has 10g complete protein!

i use healthforce spirulina, cause i think it's the best quality. you can of course also add cacao or carob or whatever else. . . i also like to add healthforce's "fruits of the earth" and some probiotics.
