Place the peanuts at the bottom of a crockpot.

Add the white chocolate chips, dark chocolate chips, peanut butter, and toffee bits into the crockpot.

Cook on low for one hour, then stir everything to coat the peanuts evenly.

Cook for another thirty minutes, then line a sheet pan with parchment paper.

Drop spoonfuls of the mixture onto the parchment paper. Sprinkle with festive sprinkles and sea salt if desired.

Allow the candies to cool and set for 30-60 minutes before serving.
