Fry the bacon in butter until golden brown. Remove from the pan, and let cool completely on paper towels.
Crumble or chop the bacon into small pieces and place in a medium-sized bowl.
In a bigger bowl, mix the grease left over from frying the bacon with all the remaining ingredients by hand, or with an electric hand mixer.
Place the big bowl in the fridge for 15 minutes to set.
Make 24 walnut-sized balls, using two spoons. Roll them in the crumbled bacon and serve.
