Thirsty Thursday; Slow Cooker Gingerbread Latte

It's less than two weeks to Christmas (where on Earth did the time go?) and yesterday I had a craving for slow cooker latte. I ended up making it a bit Christmassy; I made a gingerbread variety. I think this one could be suitable for Christmas parties as well, as it is gingerbread-flavoured and it doesn't take any space at the stove top, you only need to have in mind how many you're serving, and adjust the measurements accordingly.

Slow Cooker Gingerbread Latte
Yields 3-4 (depending on the mug etc)
1 liter milk
1 dl maple syrup
1 tablespoon brown sugar
1 tea spoon ground ginger
1 tea spoon vanilla sugar
2 cinnamon sticks
1/2 tea spoon whole cloves
Pinch of nutmeg
5 dl strongly brewed coffee
Gingerbread cookies for garnish (optional)

Add all the ingredients (apart from the gingerbread cookies) in the slow cooker and put it on high setting for around 2 hours or until heated through. When serving, use a sieve so you don't end up having cinnamon sticks or whole cloves in the coffee.
