In a mixing bowl, whisk together the dry pancake ingredients- the flour, sugar, baking powder, cinnamon, and salt. Whisk together until evenly combined.
Add the crushed cereal too the mix, and stir to combine. Set aside.
To a large mixing bowl, add the milk, melted butter, egg, and vanilla. Whisk together to combine.
Slowly add the flour mixture in to the wet ingredients, stirring in after each addition. Continue, just until all of the flour's incorporated without over-mixing.
Heat a skillet over medium high heat. Once hot, add 1/4 cup of the pancake batter to it. Cook the pancake for about 2 minutes, flipping and cooking the other side for an additional 1-2 minutes- or until both sides are a nice golden brown and the pancake has puffed.
Remove the finished pancake to a waiting plate, and repeat until all the batter's used.
