3/4 C sugar
3 TBS cornstarch
1/3 C Hershey's Special Dark Cocoa Powder
1 14oz can coconut milk - and don't you dare make it "light" (or 2 Cups of the milk of your choice - soy, almond, oat, etc.)
2 tsp vanilla extract
Pour sugar into a microwave safe bowl then sift in the cornstarch and cocoa powder. Make sure it's really blended without any lumps then whisk as you gradually pour in the milk until combined.
Place in the microwave for 3 minutes, stir, then heat for one more minute before stirring again. If it doesn't look shiny and thick, try 30-60 seconds more (but keep an eye on it or it will boil over!).
Stir in the vanilla extract then cover with plastic wrap and refrigerate until chilled.
P.S. I tried to make something brown and swirly in an olive green glass look as appetizing as possible. Hope it worked. :/
