Spray a cookie sheet with cooking spray. Grind the cereal in a food processor. Transfer the cereal to a shallow bowl.
In a large plastic bag, combine the seasoning, chicken, buttermilk, mustard, sazon, allspice and hot sauce. Seal the bag and shake well. Remove the chicken from the bag and coat with ground cereal. Put the chicken on the cookie sheet and bake until the center of the breast registers 170 degrees F. on an instant-read thermometer, about 14 to 16 minutes. Arrange the breasts on a serving platter and serve.
