Stir together milk, oil, egg and full box cornbread mix until moistened. Spoon batter into donut pan, filling 2/3 full. Bake 13-16 minutes or until light golden brown.
While donuts are baking, prepare the glaze by microwaving butter and honey until butter melts. Stir to blend completely.
Carefully remove donuts from pan, flipping each one over onto cooling rack. Immediately poke numerous holes in donuts with toothpick, and generously brush glaze over the tops of each one. Sprinkle bacon pieces over the top.
