Prepare a 13x9 pan by coating it with a cooking spray. I also like to measure out all of my Rice Krispies at this point and put them in a large bowl together. Set these both aside for now.

Prepare your chocolate bars and graham crackers. I finely chopped one chocolate bar, and then more coarsely broke up the remaining chocolate bars. For the graham crackers, I put them all in a plastic baggie and crushed them. I left some of them in chunks, and others ended up as graham cracker crumbles. Set these both aside for now as well.

Melt your butter in a large microwavable bowl in the microwave for approximately 45 seconds.

Add approximately 12 oz of miniature marshmallows to the microwaveable bowl.  Toss them in the butter to coat them.

Put the bowl back in the microwave and heat for approximately 90 seconds.  Stir the marshmallow mixture. If it’s not yet melted, heat for another 30 seconds and stir again. However, once you mix the mixture after that first 1 1/2 minutes, you will likely find that your mixture is smooth and melted.

Add the Rice Krispies to the melted butter and marshmallow mixture. Stir until coated.

Add the finely chopped chocolate bars, as well as a couple of handfuls of the more finely ground graham crackers into the Rice Krispie marshmallow mixture, and stir until combined.

Pour combined mixture into your prepared 13x9 pan and flatten your mixture into an even layer. I always just put a little bit of cooking spray on my hands, and then flatten the mixture with my hands. Set this all aside for a few minutes.

Turn on your oven's broiler and allow it to heat while you place miniature marshmallows on a cookie sheet. You can decide how many you would like for topping your Rice Krispie Treats. You might even want a few to pop in your mouth!

Once your broiler is hot enough, place your miniature marshmallows under it. Keep an eye on these so that you're able to pull them out once they get to your desired golden color. This should only take a couple of minutes or even much less, so keep a close watch on them the entire time.

Pull your now toasted marshmallows out from under the broiler.

Sprinkle your coarsely chopped chocolate bars on top of Rice Krispie Treats (still in the 13x9 pan), and put your Rice Krispie Treat pan under it for just a minute or so, in order to melt your chocolate bar pieces.

Remove your Rice Krispie Treats from under the broiler and spread the now melted chocolate all around on the top of them. Immediately place your toasted miniature marshmallows and graham cracker pieces onto the melted chocolate.

Allow to cool and enjoy!
