Reese’s rice krispies treats – when you take an already outrageously scrumptious dessert and make it even better! Gooey rice krispies treats loaded with creamy peanut butter and chunks of Reese’s peanut butter cups. I. CAN’T. STOP.

I don’t know anyone who doesn’t love a classic rice krispie treat, but imagine that with chocolate and peanut butter. Hello! No brainer! And everyone needs a few good no bake dessert recipes in their back pocket!

This is a spin on our mega viral Reese’s Krispies that you all love so much. It was our first viral recipe and it’s like my baby! I see the recipe and instantly feel all nostalgic. In fact, did you read my recent instagram post about them? I seriously relived that incredible moment, tears flowing and all to remember how far we’ve come from the dark days of being unemployed for so many years.

The feeling of being so hopeless and helpless while we were unemployed is still so vivid in my heart and mind. I had randomly made this recipe for Reese’s Krispies and posted it not thinking much about it. That night I sat down at the computer and saw that our numbers were literally rising by the second. I was shocked, and I thought there was an error for sure!

I just knew we had to take that recipe and make a bar version and recreate the magic. I’m willing to bet all the dollars that you can’t stop at just one!

How to Make Reese’s Krispies Bars

I love a good no bake dessert! No preheating the oven, no waiting for treat to bake and cool down, just make and consume! Call me impatient, but I love the ease and no waiting part of this recipe! Here are the basic steps:

  • Add the sugar, corn syrup, and peanut butter into a large sauce pan over medium heat and stir until smooth and combined.
  • Remove the pan from the heat.
  • Add the marshmallow fluff, salt and cereal and stir gently to combine without crushing the cereal.
  • Throw in the chocolate chips and stir it again. It should be cool enough to not melt the chocolate chips but still warm enough for them to stir in.
  • Fold in the mini marshmallows and then all all the Reese’s candy saving 4-5 to chop and sprinkle on top.
  • Use a piece of parchment paper to line a 9×9″ pan and spray with cooking spray.
  • Pour the mixture into the pan and spread it out. I like to use a rubber spatula sprayed with cooking spray to spread it out in the pan.
  • Top with the chopped Reese’s and let it cool to room temperature.
  • DE-VOUR!

All these instructions can be found down in the recipe card as well.

What Size Peanut Butter Cups Should I Use?

You can use any side of Reese’s Peanut Butter Cups that you want, but I like to use the minis. They require less chopping. But you could use full sized peanut butter cups. You would just need to chop them down to small pieces. I say go with whatever you can get on sale or for the best price.

How to Store Reese’s Krispies Bars

Store in an airtight container for 2-3 days.

Can I Freeze Them?

These Reese’s rice krispies treats freeze really well. Let them cool to room temperature. I like to cut them into bars before freezing them. Then place them on a cookie sheet and stick them in the freezer for a couple of hours. Once they are frozen, place them in a ziplock bag and separate layer with parchment paper.

When you’re ready to eat them, place them on the counter for about 30 minutes and allow them to thaw.

Can I Use a Different Candy Bar?

You better believe it! You can use an candy bar that you like. Some other great options could be Snickers, Milky Way, Butterfinger, Twix, or Take 5.

Can I Use a Different Cereal in This Recipe?

You rebel you! Making rice krispies treats with something other than rice krispies…unthinkable! Totally joking! Of course you can use any cereal you have on hand or whichever you like best. These are a few ideas:

  • Reese’s Puffs
  • Cocoa Puffs
  • Cheerios
  • Chocolate Cheerios
  • Peanut Butter Cheerios
  • Cocoa Pebbles
  • Frosted Flakes
  • Golden Grahams
  • Chocolate Chex
  • Peanut Butter Chex
  • Rice Chex
  • Corn Chex

Tag us on social media if you try a different cereal. I want to see a picture!
