For the praline bacon: Melt the butter in a saucepan over medium heat. Add the brown sugar and vanilla. Stir as the sugar melts and forms a caramel, about 5 minutes. Stir in the pecans.
Fry up the hickory smoked bacon in a skillet over medium heat. (You will need to do this in batches.) Pour the praline mixture over the bacon and toss like a salad.
For the burger: Grill the burger patty over medium-high heat until the center is no longer pink.
Assemble by melting the sharp Cheddar on the burger patty. Top with some praline bacon, lettuce, tomato and pickle, and place on the kaiser bun.
