Vanilla Martini

I think this would be a nice winter warmer if you added just a dab of peppermint extract to it. Maybe even top it with a candy cane or put two scoops of ice cream in it so it looks like a snowman.  This recipe makes just one, but I'm sure you can scale it up for a crowd!

1 oz homemade vanilla extract
1 oz good quality vodka (I use Sky or Grey Goose)
1/2 T simple syrup (make it with vanilla sugar and/or add a bit of vanilla extract)
A tiny scoop of frozen vanilla infused heavy cream (or vanilla ice cream)instead of an ice cube.
