Mix flour, rice cereal, baking powder, ground cinnamon, and brown sugar in medium bowl; set aside.
Beat egg, milk, and margarine with a wire whisk until well blended. Add to dry ingredients; mix just until blended. Let stand 5 minutes; stir in blueberries.
For each pancake, ladle scant 1/4 cup batter onto hot griddle or into hot skillet sprayed with cooking spray. Flip pancakes when bubbles form across the surface of the batter.
