Preheat oven to 400°F
Combine sugar and syrup in a frying pan over a medium heat for 5 minutes. Melt butter into mixture. Set aside to cool (if you’re in a rush, put the pan on a bed of ice in the sink). Once cooled, add eggs, salt and vanilla and mix.
Fill pie shell with broken pecans. Pour syrup mixture over pecans until it's just below the rim.
Place filled pie on a cookie sheet and place in the oven. Bake for 50 minutes or until the center of the pie is set.
While the pie is baking, prepare the bacon. In a small bowl, combine brown sugar, chili powder, black pepper, and cayenne. Stir until well mixed. Arrange bacon in a single layer on a broiling pan or a rack set in a jelly roll pan (line inside of the broiler pan or the jelly roll pan with aluminum foil). Bake at 425°F for 10 minutes. Remove pan from oven and sprinkle bacon slices with brown sugar mixture and then with pecans.
Return pan to oven and continue baking until bacon is crisp, about 5 to 10 more minutes. Once both the pie and the bacon are done cooking, top the pie with a generous amount of prepared Spicy Praline Bacon and enjoy!
