Place bacon in a cast iron skillet; place skillet over medium heat. Cook until bacon is crispy (~10-12 minutes).

Remove bacon from skillet and pat dry. Drain most of the bacon grease from skillet, leaving only about 1-2 tsp in skillet.

In a medium bowl, mix together the maple syrup, brown sugar, salt, cinnamon and black pepper; stir until combined. Add the cooked bacon, nuts (pecans, walnuts, cashews and almonds) and dried cranberries; stir until well combined.

Transfer mixture back into skillet; cook on low heat, stirring often, for 8-10 minutes or until sugar has melted and begun to thicken. (Note: you will need to stir the mixture fairly often to prevent the sugar and maple syrup from burning.)

Remove the mixture from the skillet and toss in granulated sugar. Spread mixture apart on a piece of parchment paper to dry (~5 minutes).
