Spray bottom of a glass 9 x11 baking dish with non-stick Pam.

In a bowl add your Rice Krispies and Lucky charms set aside.

In a large pot melt half a stick a butter. Be sure it is on low you do not want to burn the butter. Add your mini marshmallows and continue to stir until melted completely.

Add melted marshmallows to your bowl of cereals and stir with a non-stick sprayed spatula until all cereal is coated nicely. Spread in dish {using the sprayed spatula, you may need a new one} and add crumbled oreos on top or in the mix, I did both. Let sit for one hour before cutting.

mmmmmm...mmmmmm...good!
