Preheat oven to 375 and line a baking sheet with parchment paper. Set aside.

Combine sugar cookie mix and finely crushed cereal in a mixing bowl and mix well. Add butter and egg and mix together to form a dough. It will take a little work to get the dough to form, but give it time and it will come together.

Using a 2 tablespoon portion scoop, scoop dough into balls and roll in coarsely crushed cereal and place onto prepared baking sheet about 2" apart. Bake for 12 minutes. Remove from oven and let stand for 2 minutes on a baking sheet before moving to a cooling rack to cool completely.
