Peanut Butter Cup Rice Krispies Treats

They say there is a first time for everything. And these bars represent the very first time I have ever seen a recipe and made it in the same day. Sure, I have seen recipes before that I think are fabulous and I bookmark them, and maybe whip them up a few days later. But not these babies. These were same-day beauties. I saw the post in the morning, went to the store and had them ready in time for dessert. Truth be told though, few things stop my heart the way peanut butter and chocolate do. Then throw in Rice Krispies treats and you’ve completely disarmed any semblance of self-control I may have otherwise possessed. I didn’t eat a ton of Rice Krispies treats growing up, but they have somehow transfixed me as an adult. I’m such a sucker for them, and I love making all sorts of variations. This one in particular will be making many appearances in the future!

Save This Recipe
As with all Rice Krispies treat recipes, the beauty is in the simplicity and quickness with which they can be made. No oven required, and not even a stove if you choose to melt the butter and marshmallows in the microwave. It’s perfect for summertime desserts, and a great snack that kids can help make. If your house or apartment runs warm you’ll want to store these in the refrigerator so that the peanut butter topping doesn’t get too melty. No matter where you store them, though, you’ll be licking your fingers when you’re done!

Peanut Butter Cup Rice Krispies Treats
Ingredients
- 6 cups (168 g) Rice Krispies
- 10.5 ounces (297.67 g) miniature marshmallows
- ¼ cup (56.75 g) unsalted butter, (2 ounces )
- 2 cups (516 g) creamy peanut butter
- 12 ounces (340.2 g) peanut butter cups (about 40), quartered
- 1 cup (180 g) milk chocolate chips, or 6 ounces milk chocolate, finely chopped
Instructions
- 1. Butter a 9×13-inch pan and set aside.
- 2. Measure the cereal into a large mixing bowl and set aside. Melt the marshmallows and butter together in a medium saucepan over medium heat (or in the microwave for about 3 minutes, but keep watch so the marshmallows don’t puff over the sides of the bowl!). Pour the melted marshmallow mixture over the cereal and mix well so the cereal is coated. Pour into the prepared pan and use a buttered piece of wax paper to press evenly into pan.
- 3. In the microwave, melt the peanut butter until thin, about 1 minute. Gently stir in the quartered peanut butter cups and then pour over the treats. Using the back of a spoon, gently spread the peanut butter mixture evenly across the top.
- 4. Again in the microwave, melt the chocolate chips. Using a spoon, drizzle the melted chocolate across the top. Place the pan in the refrigerator to set before cutting and serving. Store in an airtight container.

I made this last week and it tasted great but the problem I have is it was a little hard to bite. Any advice?
Just made these last weekend for games night with the neighbours. HOW AWESOME!!!
I made these and posted about them – they were amazing!!! Will definitely make again! http://delishhh.com/2012/02/20/peanut-butter-cup-rice-krispies-treats/
I made these last night. So good!!!
These are amazing! My husband, a PB&C devotee, was adorable when I told him I was making them–“Rice Krispies treats come in different flavors? Why didn’t anyone ever tell me!” I think I’ll have to make these pretty often.
I made these this week, but used a peanut butter ganache instead of the peanut butter for warm weather stability. Both recipes are super tasty and easy to make!
I made these today and they were totally yummy. I don’t know about big city fancy grocery stores, but in my small town store a bag of mini Reece’s is over $4. I thought this would be a really quick, easy recipe. And it would have been but I underestimated how long it would take to unwrap and cut up 40 PB cups. I must have got my melted PB a little too hot, and I was disappointed when the chopped up PB cups just melted.
So I think next time to make it quicker, I will just use a bag or 2 of Reece’s Pieces and I will sprinkle it over the PB after it has cooled a little bit. I think peanut M&M’s would be yummy too.
Wendy, a friend of mine, brought in a dish of these tonight in honor of HER birthday, to our scrapbook evening. OMG!!! HEAVEN!!! Totally decadent and just wonderful!
WOW!!! There goes the diet…all in ONE recipe!!! Awesome!
Oh my goodness…..I had been looking at this recipe for a few weeks and finally made them for a family pool party today. They are to die for!!! EVERYONE loved them and gobbled them up….I came home with an empty pan!!! Everyone wanted the recipe. This is definitely one of my favorite recipes now!!!
I am with you on the PB and chocolate combo…it’s my ultimate weakness. I need to try making these!
I found this last weekend and made them twice this week! The second time around I chilled the peanut butter cups for a bit in the fridge so they stood up to the warm peanut butter a little better and didn’t use *quite* as much peanut butter. Then added a thin layer of dark chocolate glaze on top.
My coworkers gobbled up both batches in the blink of an eye :) Thanks for sharing!
I made these and they were AMAZING!! Rice krispie treats were my favorite dessert as a kid. Such a nice twist on this classic treat.
I love peanut butter and these were delicious, but I thought two cups of peanut butter was way too much!
I used Nutella instead of peanut butter, and a chopped up milk chocolate hazelnut candy bar in place of the Reeses cups and it turned out great! Perfect for Nutella Day 2001!
Amazing! I can’t even speak…….thanks for sharing.
Omg these are AMAZING!! I added pretzels to the peanut butter and peanut buttercup topping which gave it a nice added salty touch.
Ooooh pretzels?! Amazing idea! I love it!
I made these the other night, to mixed reviews. While they were very good, they were also very rich (too rich for our taste buds). When I make these again, I will make the following changes: (1) not press down the rice Krispie part down too much, just lightly, (2) sprinkle quartered Reese’s cups over the top, then drizzle the warmed peanut butter over the top (prob about 1 c. total, not 2 c. – it was too much), and finally (3) drizzle the melted chocolate over the top. I think with these changes, the peanut butter part will not overwhelm so much, and they will taste awesome. Overall, a great recipe.
all the people who raved about the recipe had not made it yet. I totally agree with the review which said 2 cups of peanut butter is too much, it just feels like you are biting into thick peanut butter. also, watch that the melted peanut butter is not too warm as the peanut butter cups will just totally melt into the peanut butter “sauce.”
This sounds sooooooooooo wonderful! A must try!!

Delightful Bitefuls
Made these last night..yum! The only thing I would change is the peanut butter part..once it sets it’s just like biting into a mouthful of peanut butter which is kinda off-putting for some. I have a recipe for Buckeyes that I make all the time (basically peanut butter & powdered sugar and butter). I might just make that peanut butter filling and push that onto the top and then the chocolate..might be better and like a spread out Reese’s cup!
Oh gosh, I *LOVE* your idea for the pseudo-buckeye topping! I love buckeyes and that sounds fabulous, definitely trying it myself next time. Thanks so much for the super suggestion!
These look so yummy. I wish I had marshmallow on hand. Wow. I have a feeling I will be making these soon. Thanks for the food porn pictures and the recipe. OMG.
Made these last night- OMG delicious. I mean, I knew they were going to be good. I love RKT, Peanut Butter & Reeses…But these are seriously better than I even imagined! They are so good that my husband was mad at me for sharing a few with my brother & his wife. :) Thanks for sharing the recipe! PS- I love your blog too!
Ummm, wow! These look great! It is one of those recipes that I NEED to make before I’m done being pregnant and no longer have an excuse to eat them :)
I have returned to this page numerous times over the last few days, each time dreaming of these bars. I think it’s time I actually make them myself! Love your pics btw!
I’ve baked a ton of things from your website with success it was about time for failure. And with the easiest recipe!
I dont know what went wrong, but they did not turn out at all. My chocolate chips did not melt but kind of hardened into a thick ball. Which i then tried to spread across runny peanut butter…not pretty.
I will try again though :D
I just came across this recipe looking for a snack to make for the kids today and this is just perfect…. I cannot wait to try it…. I have all the ingredients on hand and ready to go… I will try anything with peanut butter and chocolate….
Thanks..
Oh my. Now after seeing these in two different places, I think my free will has been taken away and I will be “forced” to make these TODAY. I’m blaming this all on you. :)
I wish I could express how much I adore peanut butter and chocolate. I LOVE the fact that you post so many different peanut butter recipes. Your website is my go to website for all desserts! Keep the recipes coming! I’m making these tomorrow!
Ooh… These look GREAT! Love this new twist on rice krispies treats!!
Oooh! For some reason, I’ve never been a huge Rice Krispie Treat fan, but I actually want to make these!! The addition of peanut butter makes them soooo delicious-looking!!
