Preheat oven to 325 degrees F (165 degrees C) and line a baking sheet with aluminum foil.
Tightly wrap each cocktail weenie with a slice of bacon, securing with a toothpick. Place on the prepared baking sheet and sprinkle generously, yet evenly, with brown sugar.
Bake for 40 minutes or until the sugar is bubbly and bacon is crisping up. To serve, place weenies in a crockpot and keep on the warm or low setting. Enjoy!
