Dump the cake mix into a large bowl and add the oil, water, and egg. Stir until thoroughly combined.
Stir in the cereal until well distributed.
Drop the dough by the teaspoonful onto a greased cookie sheet.
Bake for 10 to 12 minutes, or until the edges begin to brown.
Let the cookies cool on the sheet for a few minutes before removing them to a wire rack to cool. Store the cookies in an airtight container at room temperature. For optimum freshness, enjoy them within a few days. They can be frozen to enjoy later.
