Preheat oven to 300°.
Combine the first 8 ingredients in a blender, and process the mixture until smooth (about 2 minutes). Add the eggs and egg whites to blender, and process just until smooth. Divide the mixture evenly among 6 (6-ounce) ramekins or custard cups coated with cooking spray. Place ramekins in a 13 x 9-inch baking pan; add hot water to pan to a depth of 1 inch. Bake at 300° for 55 minutes or until a knife inserted in center comes out clean. Remove ramekins from pan, and sprinkle each serving with 1/2 teaspoon sugar.
Preheat broiler. Place the ramekins on a jelly-roll pan, and broil the custards for 3 minutes or until the sugar melts.
