Gather the ingredients to prepare Reese's Rice Krispie Treats

To kick this recipe off, you'll want to make sure you have all the necessary ingredients lined up and ready to go so you're not scrambling around the kitchen when it comes time to prep. And trust us — you don't want to waste any time, because you're going to want to enjoy these delights as soon as possible. Fortunately for you, the process is very quick, so you will have them done in just about no time at all.

To put this recipe together, you'll need several ingredients, most of which you may already have at home. Gather up ½ cup (or one stick) of butter, two (10-ounce) bags of mini marshmallows, 10 cups of Cocoa Krispies cereal, ½ cup of peanut butter, and ¾ cup of chopped Reese's Peanut Butter Cups (six full peanut butter cups). If your mouth is already watering, you are certainly not alone!

Chop up the Reese's Peanut Butter Cups, and melt the butter

Once your ingredients are gathered and ready to go, it's time to start making your recipe. First, you're going to chop up the Reese's Peanut Butter Cups into small chunks, and set them aside for later. (Warning: Don't start eating them, because you won't have enough for the recipe! But, if you want to buy more so you can snack while you work on this sweet dessert, go right ahead.) 

Next, you'll want to spray a 9x13-inch pan with cooking spray, along with the wooden spoon or spatula you'll be using to prevent any sticking. Once everything is prepped, put a large Dutch oven or other large pot on the stovetop on medium heat, and add in the butter. Allow the butter to fully melt. Be careful not to burn it!

Melt the marshmallows, and then combine with the peanut butter

Once the stick of butter has completely melted, gradually pour the mini marshmallows into the pot. Be sure to reserve 1 ½ cups for later. Stir the marshmallows in with the butter until all of the marshmallows are completely melted. Then it's time to stir in the peanut butter. Be sure to stir everything well to fully combine the mixture. Your kitchen is about to smell quite heavenly right about now, and your pot is going to look pretty picture-worthy as well, so feel free to grab a snapshot of your work in progress.

Add in the Cocoa Krispies

Once the liquid marshmallow and peanut butter mixture is ready, it's time to add in the star of the show: the Cocoa Krispies cereal. Gradually pour the Cocoa Krispies into the melted marshmallow mixture. Stir the mixture well to combine as you go along in this step, and continue pouring in the cereal until you've poured in the full 10 cups. Lastly, stir in the 1 ½ cups of marshmallows that are remaining. This is one yummy pot of sweetness right here.

Press, and let the Reese's Rice Krispie Treats set

Once the mixture is ready for the next step, using a spoon, you're going to empty the pot with everything in it into the greased pan. When everything is in the baking pan, press down just slightly to be sure the mixture is spread out evenly, but don't press down too firmly, as you don't want it completely compressed. For a great final touch, sprinkle the chopped Reese's over the treat, and press down slightly so they stick. Allow the treats to sit and fully cool for at least 20 minutes before cutting into squares and enjoying.

When it's time to cut up your Reese's Rice Krispie Treats, get a really nice serving platter so you can space them out for a very appetizing dessert presentation. Hey — you can even add a few whole Reese's Peanut Butter Cups scattered around your serving platter for a little creative touch. The only negative thing about this snack is it will not last for long, because everyone will want to go in for second helpings! You may just have to make more the next day — they are that good.
