Pour into food processor and add cocoa powder, spirulina powder, protein powder, goji berry powder, soy milk powder, maple syrup, and himalayan salt. Process until even. Have a taste test, if you like it adjust by adding more sugar/maple syrup. You may need to add more of the solids (protein powder, spirulina, goji berry powder—but you could also add other powders like maca powder, açai powder, wheatgrass powder, etc.).
