Have you ever watched Harry Potter, and while the gang is off at the ... place where they go during breaks ... wondered, "Hummm, I wonder what that butter beer stuff tastes like?"
Well, I'm here to let you know it's yummy. I'll tell you the ingredients that I used, but the proportions are up to you depending how strong or weak you'd like it.
Butterscotch (ice cream) topping
For sweeter, use more topping. For more of an adult kick, use more schnapps.
Some recipes online called for melted butter. I'll admit, I scaled it back and tried it. And, well, I didn't like it, but it did foam better with butter. I'd stick to the sugar and not the fat stuff though.
