Preheat your oven to 350 degrees.
Mix together the eggs, brown sugar, milk, sour cream, melted butter, & vanilla extract. Stir in the flour until just combined. Pour the batter evenly into donut tins that have been sprayed with non stick cooking spray. An easy way to do this is to pour the batter into a ziploc bag, snip off the corner, & pipe it into the donut cavities. Bake at 350 for 8 minutes.
Mix all the glaze ingredients in a saucepan & cook on medium low heat until the sugars are all dissolved. Dip the slightly cooled, but still warm, donuts in the maple glaze - then let rest on a wire rack on top of baking sheet for the glaze to set. Once the first layer of glaze is set, dip the donuts again, working in small batches (about 3 or so at a time). Sprinkle the crumbled bacon over the second layer of wet glaze. If the glaze starts to solidify before you're finished with the glazing, just return it to the heat for a couple minutes before continuing.
