Homemade Nestle Quick Syrup

I stumbled upon a recipe the other day and decided to give it a whirl.  Boy was I pleasantly surprised!  My kids LOVE chocolate milk; however the price of nearly $5 a gallon is not a fun experience much less buying a thing of Quik syrup at $3.50+.  I found this recipe and had to try it out.

Homemade Nestle Quik Sauce 
1/2 c cocoa powder 
1c water 
2 cups sugar 
1/8 teaspoon salt 
1/4 teaspoon vanilla 
1 teaspoon of cornstarch dissolved in 1 teaspoon of water. 

Combine cocoa powder and water and stir over low heat until cocoa dissolves. Add the sugar and stir until it dissolves. Boil gently 3 minutes and add salt and vanilla. Finally stir in cornstarch mixture to thicken. Pour into a clean glass jar and store in the fridge.

 When you finish this it will be VERY runny.  I was worried it would not be the same thickness quality.  Trust me.  It will after it is cooled.  Don't add more cornstarch!
