Cream the butter and sugar together until light.
Add the other ingredients, one at a time (in order of appearance) until everything comes together.
Roll into around 18 balls of a size a little smaller than a golf ball (although it doesn't matter how big or small you make them).
Place whatever you are using as decoration in a bowl and roll the balls in it until they are covered.
Place in a container and keep in the fridge for an hour or so. The chokladbollar will last several days in the fridge. Enjoy!
