Preheat the oven to 375° F. In a medium bowl, mix the ground cereal with the melted butter until the cereal is evenly coated and damp.
Dump the mixture into a 9- or 10-inch tart pan or pie pan, and press in evenly, using a spoon, the flat bottom of a cup, or your fingers (it helps to put a layer of plastic wrap over the crust in this case).
Bake the crust for 7 to 9 minutes, until it is a deeper shade of brown and dry-feeling. Monitor it closely so that you can turn the oven down if it's browning too quickly.
