Peanut Butter Smore Rice Crispy Treats

Grease a large casserole dish with pam and crumble graham crackers into the bottom. Make rice crispy treats as you normally would (though I use more marshmallow and less rice crispies for gooeier treats).
Spread into graham lined casserole. *Hint - getting your spatula wet or spraying it with pam keeps the marshmallow from sticking to it.
In a bowl place 1 TBSP butter with your choice of chocolate. I like M&Ms for the candy coating crunch.
Melt in the microwave stirring frequently. When the chocolate is almost completely melted, add peanut butter and continue microwaving.
Stir and spread over top of rice crispies.
*Mix it up and instead of using all rice crispies - mix in puffed millet or puffed wheat. Or use a different cereal like cocoa crispies, cinnamon toast crunch or honey chex!
