I think they're pretty perfect for Valentine's Day, too. Or basically any day you could use some hot chocolate. Which, with current temperatures is every day, if you ask me.
I used the recipe from giver's log, which you can find right here. There's also a helpful review at TheKitchn.
I think I made about six batches in total, and after a while found that it worked best if I doubled the recipe. We also added some spice to the chocolate. As for what kind of chocolate, well, I mixed what I had on hand, nothing with less than 70% of cocoa though. For a mold, I used those tiny flowery mini muffin tins I've had for ages and never seem to be able to find the right muffin recipe for. They were perfect and after popping the whole tray in the fridge for it to set, they came out easily. The silicone molds were even easier, but mine are quite big which makes for a very chocolatey cup later...
For the Christmas batch I ended up printing those lovely tags from A Pair of Pears to go with them. They were perfect and added just the right touch. Of course I did not manage to get a photo of them. Sigh.
I think they look pretty just wrapped individually and tied with some ribbon, too. Or you could write a message on the stick, tape a little flag to it...
As for the hot chocolate, well, we made extensive quality assurance tests, let me tell you. The brother's verdict: pretty good. In fact, good enough to have everyday. Morning, afternoon and at night, please. If you ask little brother, he'll also tell you that you absolutely must make some freshly whipped cream to go with it. And while you're at it, some sprinkles don't hurt, either.
Red heart sprinkles, maybe?
Happy Valentine's Day,
