Last month I made White Hot Chocolate using this recipe: http://whipperberry.com/white-hot-chocolate-recipe/
I liked it but it can taste a bit overpowering, maybe because of the cream, chocolate and vanilla all mixed together. Also I might have put too much vanilla in. It was nice to have for a change but I wouldn't drink it all the time. It will be spring officially this week when we have the Spring Equinox on 20th March* (I'll do a post on Oestara, the sabbat, later) and while the days are warmer it's still quite chilly at night, so I'd recommend trying the White Hot Chocolate if you feel like a hot drink. :)
Here's a picture of mine. I can't remember exactly why it came out a bit yellow but I think I might have heated it for too long. I didn't use a slow cooker because I don't have one, I used a saucepan instead. Maybe it tastes best if you use a slow cooker but it's still worth trying if you don't have one.
*In the northern hemisphere, in the southern hemisphere it's reversed so it will be their autumnal equinox.
