This literally takes about 15 minutes to put together and less than 30 minutes to "set".
3 tablespoons butter
1 bag large marshmallows (10 ounces)
1/2 cup peanut butter, plus 1 1/2 tablespoons, divided
6 cups crisped rice cereal
1 1/2 cups chocolate chips (or if you're like me, you'll just use the whole bag)
1 1/2 tablespoons peanut butter
Lightly grease (I just rub butter all over the inside) a 9-inch x 13-inch pan and set aside.
In a large pan, melt the butter over medium heat. Add the marshmallows and stir constantly until melted. Remove from the heat, add the peanut butter and stir well. Add the cereal and stir until well combined. Carefully press into the pan with wax paper or buttered fingers.
Mix together the chocolate chips and 1 1/2 tablespoons peanut butter and melt (easiest in one of those glass measuring cups in the microwave, stirring every 30 seconds until melted). Pour the chocolate over the crisped rice treats and spread evenly. Let sit until the chocolate is set (I place the dish in the refrigerator - it's faster!). Cut and serve.
