Start with a batch of your favorite Sugar Cookie recipe or use some store bought sugar cookie mix.
Remove and set aside. Next you will need: 2/3 cup Corn Syrup 1 cup Peanut Butter Chips 2 and 1/2 tsp. Vanilla 4 Tablespoons salted Butter (NOT margarine) 1 1/2 cups rice crispies 2 1/2 cups salted peanuts. While the cookie base layer is baking, heat corn syrup, peanut butter chips and butter and vanilla until melted over medium heat, in a large saucepan, stirring occasionally to ensure it doesn't burn. Do NOT bring to a boil.
Stir in rice crispies and peanuts (you will need a big wooden and some muscle), reducing the heat to warm until cookie/marshmallow base is done.
Spoon over crust/marshmallows carefully and spread evenly (Spraying your spoon or spatula with a little non stick spray will help keep it from sticking.
Melt 1 bag mini dark chocolate chips in bowl in microwave 1-2 minutes, stirring every 30 seconds or so. Pour over peanut layer.
When cool, cut into bars or small squares.
