In 12-inch skillet, cook bacon 8 minutes over medium-high heat or until crispy around edges. Remove from skillet; drain on paper towels. Reserve 1 tablespoon bacon drippings; set aside. Microwave frozen corn as directed on box. Pour into medium bowl; set aside.
In blender or food processor, place 1/2 cup of the sweetened condensed milk, 1 cup water, egg and 3 tablespoons of the corn and butter sauce. Cover; blend on high speed 5 to 10 seconds or until smooth.
In 2-quart bowl, place milk mixture, flour, bacon drippings and the remaining corn and butter sauce; mix until blended. Set aside.
Spray griddle or skillet with Crisco® Original No-Stick Cooking Spray. Heat over medium-high heat (375°F). Stir batter; for each corncake, pour about 1/4 cup batter onto griddle. Crumble 1/2 slice cooked bacon over each corncake. Cook 1 to 2 minutes or until bubbly on top and dry around edges. Turn; cook other side until golden brown.
Meanwhile, in medium microwavable bowl, mix the remaining sweetened condensed milk and maple-flavored syrup. Microwave on High 30 to 60 seconds, stirring once, or until thoroughly heated. Serve over corncakes.
