Place chicken in a 9- x 13-inch baking pan. Spread mayonnaise on chicken and sprinkle with half of the spices.
Combine Rice Krispies with the remaining spices. Top chicken with Rice Krispies mixture (toss Rice Krispies before adding to the chicken because the spices have a tendency to settle at the bottom), covering all surfaces. Pat Rice Krispies down gently.
Cover well and bake for 1 ½ hours. Uncover and bake for an additional 30 minutes.
