Separate the marshmallows from the cereal so that you have one Cup of cereal. Set the marshmallows aside - you'll need them later!
Add the cereal to a plastic bag, seal, and use a rolling pin until the cereal is coarse crumbs. You can also use a food processor, if you prefer.
In a small bowl, combine the flour, cereal crumbs, brown sugar, baking powder, and salt. Mix well.
In a medium bowl, whisk together the milk, melted butter, egg and vanilla.
Add the dry ingredients to the wet ingredients and mix until just wet - do not over mix.
Heat a griddle to 350°F. Spray with non-stick cooking spray or coat the griddle with butter. Scoop out batter to desired size. Cook until bubble form on the top, flip and cook an additional 1-2 minutes, until lightly browned and cooked through.
Top the finished S'mores Cereal Pancakes with additional cereal and the saved marshmallows. These pancakes also taste great with added maple syrup!
