Homemade Hershey's Chocolate Syrup

My sons love chocolate milk, my daughters have been VERY into chocolate milk lately also. So, I make this syrup about 2 to 3 times a month. What I like to do is make a triple batch, and then mix up chocolate milk in a 64 oz mason jar to keep in fridge for whenever they want it. 

You Will Need: 
3/4 Cup Cocoa Powder
1 1/4 Cup Water
1 1/2 Cup Sugar
1 1/2 tsp Vanilla
Dash Salt 

That is it.. Cook all ingredients on stove until sugar is dissolved, remove from heat, stir in vanilla. Enjoy!
