Peanut Butter Rice Krispies Treats are the ultimate childhood favorite. This recipe is special because it keeps the treats gooey and soft!
PEANUT BUTTER RICE KRISPIES TREATS
My Mom is a peanut butter nut (pun intended!) She loves peanut butter cookies and of course, she couldn’t pass up the chance to put peanut butter in Rice Krispies treats. When you grow up eating things a certain way, you just become accustomed to it. So now, this is the only way I like to eat them. I think my particular recipe for these is the absolute perfect balance between chewy and crunchy and peanut butter. 
VIDEO INCLUDED BELOW:
TIPS FOR MAKING THESE GOOEY TREATS:
- If prefer a slightly thicker bar, go with an 8×8 baking dish.
- Also, for all you budget-conscious shoppers, I have made this recipe with the store brand cereal, marshmallows, butter and peanut butter and these treats still turn out delicious.
- And if you’re a Krispies treats purist, just leave out the peanut butter, they’ll still be gooey.
- As with all Rice Krispies treats, they are best eaten the day they are made.
- Store in airtight container if you don’t eat them all the same day. I like to nuke them in the microwave for about 5-10 seconds when they start getting a little stale.

PEANUT BUTTER RICE KRISPIES TREATS
Ingredients
- 4 tbsp salted butter
- 5 cups mini marshmallows
- ½ cup creamy peanut butter
- 5-¾ cups Rice Krispies
Instructions
- Spray an 9" x 13" (or 8" x 8" for thicker bars) casserole dish with nonstick cooking spray.
- In a 4 quart sauce pan, melt butter on low heat. Do this slowly, you don’t want burned or brown butter here.
- Once butter has melted, keep heat on low and add mini marshmallows.
- Once marshmallows begin to soften and melt, add peanut butter.
- At this point, you will need to constantly stir the mixture so the peanut butter does not burn and the marshmallows can evenly melt (won’t take too long, about 5 minutes or so).
- Once, mixture is combined and melted, turn off heat and remove pan from stove.
- Add rice krispy cereal to sauce pan and stir until evenly coated with mixture. This is sticky stuff so do your best to get it all combined.
- Pour mixture into casserole dish (it will look very loose.) Spray your hand with some nonstick cooking spray and pat down the mixture until firmly compacted.
- Allow 30-45 minutes for treats to set up.

this recipe looks great. I'll be trying it for my children. thank you for your wonderful comments at my blog. I hope you enjoy the pulled pork if you give it a try!
Make with coco Krispies…. Just saying…..mmmmm
Thanks for the great comments everyone! I guess this post totally gives away my age, but hey, it is what it is. I'm not growing older, just wiser (I hope!) Haley – glad you get my sense of humor!
These look amazing……I have to make them. What a great story too. My husband does the "swan man" on me practically smashing my lungs, so I understand the whole steamroll thing:) And the hair……I love it! Man them 80's were something else:) Thanks for the great recipe:)
80's were my "growing pains" years too! Ohhh so long ago, can't even imagine that this summer will be already 25 years since I graduated from high school! Love the pics! We all love the Rice Krispie Treats, but we have a problem with gelatin that is an ingredient in marshmallows. Is there anything else I could use instead, maybe a thick simple syrup?
I am a huge PB lover, but surprisingly have never tried adding it to Rice Krispy Treats! This is on my "must make" list for the next time I make goodies!
Ive made these peanut butter rice krispie treats then frost with choc frosting they are so yummy
Mateja – I believe Marshmallow Fluff is gelatin free. I'm pretty sure the Jet-Puffed brand of marshmallow creme is gelatin free. You would probably have to use a whole jar of it to replace the amount of marshmallows used in this recipe. Still add the butter though. I hope this helps.
Great blog!
Oh my gosh! These were the best krispy treats I have ever made!
I love your peanut-butter rice krispies..they look fantastic!
Love this twist on one of my favorites!
I love these PB Rice Krispies Treats. This is the best recipe I have ever made for these!
Another great recipe 🙂
These look wonderful! I love PB fudge, but I don't think I've every tried adding it to the Rice Krispie Treats! I've got to give it a try.
Thanks for sharing.

What a lovely post! These are a favorite-second only to Scotcharoos!!!
very touching post..and I love the hair 🙂
I better close this page asap or i have to make these treats right now. my husband loves peanut butter and these are definitely going to trigger his sweet tooth.
So good!!
I know four little boys who will love your krispy treats. I'm new to your blog and I can't tell you how much I've enjoyed my first visit here. I've been browsing through your earlier entries and really love the food and recipes you feature here. I'll definitely be back. I hope you have a great day. Blessings…Mary
These were awesome and I didn’t change a thing!
Like others, I have never come across a PB Krispy treat, nor would I have thought it up. But these were AWESOME!!!
You're making me very nostalgic myself lately! Doesn't help that I haven't seen my parents or brother in 2 years… 🙁 I'm going to be making some old family favorites myself this week!
Gotta love the '80's! I had hair like that once!
Thank you for visiting my blog! Come back to visit any time..never know what I'll be up to!
I'm following yours now too!
My mother loved peanut butter, and she passed on her PB love to me. (Thank goodness there no peanut allergies in our family.) She did make PB fudge, but never the Rice Krispy treats. I can't believe that I've never made them before. These are amazing!
I'm loving your PB Rice Krispys and your blog!!!
Definitely 5 stars on this recipe!
I've never had a peanut butter rice crispy treat. I don't know why because it's such a good idea!
I love peanut butter and the husband loves rice krispies – these sound like a match made in heaven!
The throwback pictures are priceless!
So, so good! Who knew something so simple would be so awesome!
Delicious! Rice crispie treats are our favorite but add peanut butter and oh my!!!
This recipe looks delicious. I do something similar using mars chocolate bars, and my kids love them. I will give you the recipe in the near future. Thank you for sharing this recipe version with us.
Made to your recipe – absolutely yum!!
I'm a peanut butter fan so I will definitely try these.
Oh Yummy! All the big "little" kids around here just love thesePeanut Butter Rice Krispies Treats.
Yum…this is one of my childhood favorite! So glad you put peanut butter in it for a twist! 🙂 I'm going to try it soon.
I've never thought of adding peanut butter to these, good idea and yum!
O Yeah! Your Krispies treats are totally different from mine. I'm not an American, my husband is, so I'm trying to learn all those foods that he likes or he used to have as a child. I'm curious myself how it tastes! So far I've learnd so many different ways to use Peanut Butter. That's just crazy 😉
The next thing I've dicovered are Rice Krispies…
Anyway, thanks for sharing this recipe, looks delicious!
thanks for posting this recipe. it sounds so yummy. I look forward to making it for my peanut butter loving husband 🙂
Before you spread them in the pan, try adding about half a bag of chocolate chips as well. Don's mess too much or the chips will melt, but that's not bad either! Double yum!
My mom used to make peanut butter Rice Krispie treats. She used government peanut butter and it was the only thing government peanut butter was ever useful for as, thick as spackling, you couldn't even spread it on bread. It lent a certain flavor that none of the name brand peanut butters can quite achieve. They sure were delicious!
Love these things! I have made them also with additional add-ins from time to time.. crunchy PB instead of creamy, adding some crushed dry roasted peanuts, even coconut one time..all delicious! Now, I'm craving them!
I’d like to make these a day ahead for an event, have you tried reducing the amount of cereal for more chewyness, or…? Or do they stay nice & chewy for a day or 2 anyway? Thanks!
Amazing recipe
Thank you so much!!
These are really good using cocoa krispies or cocoa pebbles. Chocolate and peanut butter, yum!
Thanks for the revipe.
I just followed your recipe but pushed a bunch of Sixlets into it. Why let that Easter candy go to waste, right? Thanks for sharing!
I’m 64 and I never knew people ate Rice krispie treats w/o peanut butter. They use to make then that way in our school lunches in the public schools. So, I’m sure you understand why I consider the peanut butter ones as the original ones. I don’t like the commercially made ones at all. So, thank-you for the recipe! I do appreciate it.
I’m only 46 but that is how they made them at our elementary school. They were my favorite! I’ve tried to duplicate them, but they just don’t taste the same. I’m not even sure if they even had marshmallows in them.
I tried the recipe and it was absolutely amazing and fun. Thank you
Really want to make these but only have regular sized marshmallows. Does 5 cups of mini equal 1 bag of the regular?
Oh my , they are off the chain. I had them in school and when u saw your recipe , I said that’s it and made them . Took me way back . Thanks for sharing.
I can cook/bake about anything. But rice krispy treats NEVER turn out for me, until now! These turned out absolutely perfect & tasted amazing!thanks!!
These Rice Krispie treats are ridiculous!!! They’re addicting! Thanks for the amazing recipe.
I made them with honey instead of marshmallows
It was a big hit everyone liked them and asked for more
It is also healthy for you. Doubled recipe 1 cup of crunchy peanut butter, 3/4 cup honey, vanilla and butter.
Love hearing that Donna!
This so true, I’ve been making them every 2 days when they run out for the last 3 weeks! They’re literally addictive lol.. I started adding less marshmallows (4 1/2 cups instead) because I don’t like them gooey.. I also add a little less peanut butter (about a spoonful less) because I don’t like them to be too peanut buttery.. they’re so good!
Love hearing that!! Makes my day – thank you!!
Thanks for the idea, I didn’t follow your exact recipe but I used your idea of putting peanut butter in them. I’m glad I did, thanks.
Thanks so much for coming back to comment. Love that you made it your own way!
Perfectly easy and yummy!
Thanks so much Mary!
I melt the butter and marshmallows in my crock pot on LOW. Takes about 45 mins. and does not burn. Then I add the cereal to the crock pot and mix until all coated. Put wax paper in a 9×13 pan and pat in the mixture. Let set and then lift paper out of pan and cut. Very easy cleanup.
Great tip Annie!! Thanks so much!!
I like the crockpot idea! I made these for a pool party, my granddaughter helped. I cut them up and put in the freezer since the party was 3 days away. Came out perfect!
Yay!! That’s great! Thank you Jane!!
How much marchmellow cream would I use instead on mini marchmellows?
Hi William – I haven’t tested it but I believe you would need at least 2 1/2 (7 oz.) jars of the Marshmallow Creme.
This was a lovely recipe – thanks so much! I made it yesterday for my husband’s (very late) Father’s Day dessert. My one change was to add the peanut butter at the same time as the marshmallows – they both just melted in together. Thank you again for a wonderful recipe – I know it’s going to be a staple in our household!
Diana
This Should be the only Completely Rite way Who in the would wouldn’t Automatically just know Peanut Butter Belongs in the Recipe as much as Snap,Crackle&Pop ..U Your Mother and My Mother just must be in the few that recognize Gooder than Good, We are Bless and Thank for the Reminder on how to get it right Hope’s are letting her taste one and memorize come back Bless you and yours
I have been making these for about a year now..(keeping the cereal and marshmallow people in business!! Lol)..but I gave them a twist. I use cocoa crisp rice cereal. Or 1/2 & 1/2, plain & cocoa.
Everyone calls it “crack” cause they cant stop eating it! Hehe
Hahaha! Love it Christi!! Thanks so much! Great idea 🙂
This is a peanut butter lovers dream come true. This will be a family favorite from here on out.
Always love hearing that!! Thank you for taking the time to comment, Crystal! 🙂
I am such a fan as well as the rest of my family,I also will use fruity dino bites minus the P.B but ooooh so good.
I have a question do you bake them in the oven. On what temperature and how long or not .thank you curious
Hi Vanessa! No baking necessary. These are a no-bake sweet treat 🙂
Great recipe! I absolutely love this layout of instructions, pictures and recipe. Thank you!
