Choose a large mug. Stir the maple syrup into the soya milk inside it.
Spoon over the protein powder, cocoa, flour and baking powder. Beat with a fork, scraping the base, to a thick lump-free batter.
Microwave on high for 1 minute 30 seconds. Keep going in bursts of 15 seconds until the surface looks set and a skewer pulls out with only a few crumbs.
