I think this is similar to what I made. Used Little Smokies last year because Wife and Kids like them. May have put some cheese on them as well.
I think I also did them with regular hot dogs.
Recipe
Ingredients
1 pound sliced bacon, cut into thirds
1 (14 ounce) package beef cocktail wieners
3/4 cup brown sugar, or to taste
Directions
Preheat the oven to 325 degrees F (165 degrees C).
Refrigerate 2/3 of the bacon until needed. It is easier to wrap the wieners with cold bacon. Wrap each cocktail wiener with a piece of bacon and secure with a toothpick. Place on a large baking sheet. Sprinkle brown sugar generously over all.
Bake for 40 minutes in the preheated oven, until the sugar is bubbly. To serve, place the wieners in a slow cooker and keep on the low setting.
This ISN'T the exact recipe I was thinking of but pretty close.
Thank you. Have a Merry Christmas.
