Cook the bacon in a large skillet. Lay the bacon strips in the cold pan and then put it over the burner over medium heat. Cook until crispy, flipping once. Drain on paper towels and crumble.
Make your dough by dissolving the yeast and 1/4 cup brown sugar in the water.
Add in the bacon drippings, crumbled bacon, and flour and mix until combined. No need to knead. Let the dough rise in a warm place until almost doubled (about 20 minutes).
Divide the dough into 8 golf ball sized lumps. Roll each ball into a snake or rope. Twist them into pretzel shapes (or whatever shape you'd like!).
In a shallow pan, beat together the milk and eggs. Add in the cinnamon, vanilla, and 1 tablespoon brown sugar. Whisk until combined. Lay each pretzel in the egg mixture and let sit for 5 minutes. Flip and let sit another 5 minutes. While they are soaking up the egg mixture, preheat the oven to 500 degrees.
Spray a baking sheet with non stick spray. Lay the soaked pretzels out on the pan and bake at 500 degrees for 7-10 minutes, until golden brown.
Remove from oven and brush with melted butter. Sprinkle brown sugar on top.
