A moisture-sensitive powder layer adheres to a grain-based food product such as ready-to-eat (RTE) cereal. The binding layer allows the powder to disperse into a liquid such as milk added just prior to consumption. The moisture-sensitive powder features one or more components of interest, which includes but is not limited to fizz powder mixes, flavorings, coloring agents, pro­biotic microorganisms, cocoa, sugar, mint, glitter, small particles of gel-like pieces, chocolate shavings or small pieces of dehydrated fruit or nuts. Such components enhance the experience of eating an otherwise nutritious grain-based food product or cereal.
