Step 4: Finish
To finish the cups, add a spoon of chocolate to the top, give a bit of a shake, and let them cool.
With a bit of practice I could do better, and so could anyone else. But the things worked, I ate one it was just fine (and I don't really like these things).
I made 10 cups from the ingredients, they'll be ~40g (twice the Reese's) ~200 kcal.: they are high in fat and sugar.
