Preheat oven to 425F degrees. Line baking sheet with parchment paper.
In a small bowl, combine brown sugar with dry mustard.
Cut up each brat into three pieces (you can make them smaller if you like).
Cut up each bacon slice into three pieces as well.
Wrap each brat piece with a slice of bacon.
Roll each bacon wrapped brat into the brown sugar mixture. Then place on baking sheet and continue with the rest of them.
Bake brats for 25-30 minutes, until bacon is crispy.
These brats do produce some grease from the bacon. If you'd like, after baking, you can place the brats on some paper towels before putting them on plates to absorb any extra grease.

Notes
To serve, just insert toothpicks in each one. And serve with your favorite types of mustards; yellow, honey mustard, spicy brown, etc.
