It really is simple to make. I brewed a good strong cup of flavored coffee. Vanilla cream is good but if you can find Irish cream it would be even better. There are several companies that sell that variety, most are online companies.
In a small bowl, I poured about 1/4 cup of whipping cream and added 1/2 teaspoon to 1 teaspoon of sugar. I whipped it until it is just past frothy and beginning to hold together. If it forms peaks you have whipped it too long.
In my cup, I first put a heaping spoonful of brown sugar.
You can dust the top with cinnamon, if you want. This one was good without cinnamon. You aren't supposed to stir it, but I kind of like it stirred. This makes a nice after-dinner dessert treat and I don't think it would be any better by adding little Irish whiskey, but I might be in the minority on that.
