I don't know about today's junior high cooking classes, but for at least 30 or 40 years these were one of the first things students would learn to make in Home Ec class (later called Consumer and Family Science and who knows what they are calling it now...).
Now that I'm a grown up, I shudder at the 2 cups of sugar that is usually in it as well! Sometimes these are made with peanut butter but this week I opted for the non-peanut butter version. IF YOU WANT TO ADD PEANUT BUTTER YOU CAN. Just add a 1/2 cup of your favorite peanut butter to the hot mixture and stir smooth and then add the vanilla and oats.
If you are not using Truvia but are using Ideal or Just Like Sugar, etc. those measure cup for cup like sugar so you can use 1 1/2 - 2 cups. If you use Truvia, it only takes half the measured amount so you use 3/4 cup. I also like to add about 10 drops liquid sweetener as I think the mixture of at least 2 natural sweeteners gives a better flavor and sweetens better than just using 1 single sweetener.
