Combine first 8 ingredients (through salt) in a large bowl, stirring with a whisk. Fold in rice square and bran flake cereals. Spread cereal mixture on a parchment paper-lined baking sheet. Bake at 275°F for 25 to 30 minutes or until cereal mixture is tacky but not moist. Remove pan from oven; cool 30 minutes.
