Pour the soymilk into the saucepan.
Gradually mix in the cocoa powder, then add in everything else except the cornstarch.
Turn up the heat to medium-high and cook, stirring occasionally for 3 minutes.
Add in the cornstarch, and continue cooking and stirring a little more frequently, until mixture comes to a boil.
Boil for 1 minute, or until thickened, and then take the mixture off of heat.Cool until you can handle it.
Goes great on peanut butter cake, brownies, blondies, cupcakes, choco cake, or any dessert!
