I have been making this recipe for a long time and have made many variations but this time I replaced all the flour with pscience casein isolate protein. The recipe is 20g Hershey's cocoa, 45g Psience protein, 60 monkfruit, bakingnpowder, salt and 150ml Coke Zero. Bake at 180c• for 25-30 min. It comes out dense and crumbly which impressed me and gave a good size.
