MIX cornmeal, flour, baking powder, baking soda and cheese in medium bowl. Add buttermilk, eggs and bacon bits; stir just until blended.
HEAT oil in large saucepan to 375°F. Drop tablespoonfuls of batter, in batches, into hot oil; cook 2 to 3 min. or until browned on both sides. (Hush puppies will float to the top as they cook.) Remove hush puppies from oil with slotted spoon; drain on paper towels.
PLACE in shallow pan in warm oven to keep warm until ready to serve.
