Notes

Nutrition Information : The amounts listed do not include any topping such as ice cream or whipped cream. 
Boiling Water : Make sure that you are boiling water for this recipe and NOT just using very hot water from the kitchen sink tap. You need boiling water. I use an electric kettle (which I have linked above in the recipe card) to boil water. You can also just use a pot on the stove top, over high heat, to boil water.
