I’m not even kidding. There are FIVE ingredients in this recipe!
1 + 1 + 1 + 1 + 1 + oven = Delicious!
6 – 1 = Easy!
Peanut Butter + M&Ms = Happy!
Math lesson over. Moving on.
I saved that picture as “Oh-Yum.” Seems to me it is much more descriptive than “M&M-Peanut-Butter-Bars-3.” Tell me you don’t agree!
These bars are not only insanely easy to make, but they are so delicious. Soft, chewy, and super sweet. I’d recommend a big glass of milk and coffee. And small bites that savor each morsel. Notice I said small bites, not small bars.
M&M Peanut Butter Bars
adapted from What Megan’s Making
3/4 cup peanut butter (I used creamy, but I bet chunky would be great too!)
2 large eggs
1 cup packed brown sugar
2 cups all-purpose baking mix (Bisquick, for example)
1 bag of M&Ms (I used regular–but now I’m thinking peanut butter M&Ms would be W-O-W)
1. Preheat oven to 325*F. Spray an 8-inch square pan with cooking spray.
2. Combine peanut butter and eggs until well mixed and smooth.
3. Add in brown sugar and stir until combined.
4. Stir in baking mix until moistened (I used my hands because the spoon wasn’t cutting it for me–it is a very thick batter).
5. Fold in M&Ms. Again, using my hands worked best for this step. Not all of the M&Ms stuck in the batter (or perhaps it would be more accurate to call it dough). I just shoved them in when I put it all in the pan.
6. Spread mixture in greased pan and bake for 35-40 minutes or until golden brown.
Verdict: I think I covered this already, but if you weren’t listening–they are delicious! VERY sweet though, in all seriousness, they are best in moderation.
Husband’s take: He didn’t have any. He’s not the biggest fan of peanut butter desserts. Crazzzzzy. I’m quite sure he was silently cursing me for not making his favorite treat.
1-year-old daughter’s take: None of these for her! Sorry kiddo. Now, before you start thinking that I ate the whole pan–I brought these to the kid’s birthday party to share with family and friends.
Changes I would make: None!
Difficulty: Five ingredients folks. Should we review the math lesson? This recipe is EASY!

The 8 year old in me just got very excited; I use to eat these everyday as a kid. Yumm!!!
Thanks for the math lesson.
Those M&M’s are popping out of your photos! I want, I want, I want!
Yes Please!! I think I could down that pan in day – it looks so good! Can’t wait to try these, and I will be trying your PB M&M suggestion!
These look incredible–it seems too good to be true that I only need five things to make them! Or perhaps just too dangerous…
Simple and delicious looking, great recipe!
Wow I cannot believe these have bisquick in them. I would’ve never guessed. And I am totally with you on the peanut butter M&Ms. I just so happen to have bought a bag recently… O:-)
LOVE these! Great, easy dessert
These look great! Love the ease.
Want to send some my way?
If there were any left, I would be more than happy to get them out of my house!
Wow! This looks amazing and is so simple. Love!
Im 5 ingredient sold! These look awesome!
using the traditional m&ms makes them so bright and colorful! Love
You can’t go wrong with this math. And I agree with Rachel, the M&M’s add so much color and fun. Wish there were some left for you to share with us!
I can handle 5 recipes when it comes to baking!! Yum!
And I have to say…they were delicious! I was at the birthday party and I passed on the cake but couldn’t pass these by–mmmmmm.
You had me with the title. It could have had 20 ingredients. That’s right 11+9=20 or 30-10=20. It wouldn’t have mattered. M&M’s AND Peanut Butter! YUM!
How do I love thee…let me count the ways! Okay, no more math but I am going to have to make these!
YUM indeed! Those look dangerously good.
I am going to the kitchen now. I made cookies not to long ago like this but the M&Ms up the bounty big time. Love it!
These look unbelievable. I’m with you – just as excited about a 5 ingredient recipe! Wahoooooooo!
They ARE unbelievable! Let me know if you try them!
My mouth is salivating just thinking about these. Stop posting such great recipes! I feel fat already! lol.
I made these with flour and peanut butter M&M!s and they are amazing!!!! Thank you for sharing the recipe!
Glad you liked them! Thanks for commenting
What if you substituted the peanut butter for nutella?
Hmm–I don’t see why that wouldn’t work. I haven’t tried it, so no guarantees, but I definitely think it is worth a shot, sounds amazing! Let me know how it goes if you try it.
What size bag of M&Ms did you use?
My mother gave me a color assortment plastic box thing full of M&Ms so trying to figure out about how many!
I used the medium sized bag–I believe it is in the vicinity of 12oz.
I JUST made these and they are delish! I used the mini milk chocolate m&m’s and just about a cup of them. So yummy and easy to make! Thanks!
Hooray! Glad you liked them, thank you so much for coming back to tell me
These are wonderful! So easy to make. I just mixed up a batch for a Christmas dinner tonight. Finally a different, and easy recipe!
I’m so glad you enjoyed them! Merry Christmas!
Can the “all purpose baking mix” be the just-add-water kind? What do you recommend? These look fantastic!
Probably! Definitely worth a shot!
I am at lost for words. I LOVE these. Right look, right texture, and *definitely right flavor. To say these are a keeper would be an understatement. Thanks for the share!
Thanks for the nice comment! They were delicious!
These are amazing!!! I made them with peanut butter m&m’s this time, soooo good! Next time I am going to try regular m&m’s and add some chopped peanuts as well
Thanks for the recipe!!
Mmmmm, peanut butter m&ms. Peanuts sound great too, or just chunky peanut butter. Glad you enjoyed!
I don’t have Bisquick but I do I have Krusteaz pancake mix, could I use that? Can’t wait to try these!
Hmm, I’m really not sure! I don’t think they have quite the same ingredients so it might not work. Worth a shot though–let me know if you do end up trying it!
I ended up getting Bisquick with a coupon
These were DELICIOUS! Mine were soft on the inside which I love!
Just made these and they were amazing. Thank you so much for the recipe!!!
Saw these on pinterest. We love easy, delicious recipes. This was so good and easy. I do think that next time we will use fewer m&m’s and will try the peanut butter m&m’s. Great recipe! Everyone should try at least once!
Thank you Sharie! Peanut M&Ms would be GREAT in these!
Can I use just regular flour?
No, but I searched online and found that you can substitute for Bisquick using this formula (found on Wikipedia):
2 cups flour
3 teaspoons baking powder
1 teaspoon salt
2 Tablespoons oil or melted butter
Make it a little more than 5 ingredients, but at least you won’t have to make a special trip to the store! Let me know how it works out!
I tried to make my own Bisquick to make this recipe because I live in South Korea and they don’t have Bisquick. It didn’t work well. It was too dry and crumbly. Tasted okay, but not as good as everyone was raving about. Someday when I live in the US again, I’ll have to try these again, but I don’t recommend making the Bisquick yourself!
Shoot! Sorry to hear that!
Thank you I will
OMW!!! These are SO super easy and quick to make!! Made some as a surprise for my husband and I hope he likes them!! I am also making some for Easter with Easter colored M&M’s
I’m so glad you enjoyed them! I love the idea of Easter M&Ms! Fun
I tried with the gluten-free variety of Bisquick and they are delicious! The bars are a little crumbly (but still not cooled from the oven); I am hoping they firm up by tomorrow but even if they don’t ( and I have to add extra liquid next go round), the taste will carry them through! thank you!
Awesome! Thanks for coming back to let me know!
Just found these not too long ago on pinterest and I have been thinking of them ever since! I finally had the perfect opportunity to make them as my in laws are coming tomorrow! They’re so easy to make and they look so delicious baking in the oven! My suggestion- use M&M minis! I just love the crunch and the bite after bite full of chocolate! I’m sure the PB M&M’s would be great too, but the minis are so irresistible! Thanks so much for the recipe
Glad you liked them! Thanks for coming back to let me know
Loved how easy this looks! Do you need an electric mixer or does a plain wooden spoon work? Thanks!
The dough/batter is SO thick that I don’t think an electric mixer would even work. A wooden spoon + your hands will be your best bet!
Just finished making these and holy moly, they are fabulous! Super sweet though, but taste sooo good! Thank you so much for posting this recipe!
Just tried making these using pancake/waffle mix. Theyre in the oven now. Also only had a tiny single sized bag of M&M’s so added a handful of chocolate chips. Hoping pancake mix works.
Hmm…not sure if it would work or not. Did they turn out?
So I had to make these… Like tonight at 10:45 pm and let me tell you- AH-MAZ-ING!!! I promised my 3 year old I’d make some and he could have them tomorrow…. I am having trouble with stopping at just one!! Trying out some of your other recipes soon! Oh I made these with gluten free bisquick as I have celiac disease- never had them a different way but great this way. Do you think almond butter would work as well??
So glad you liked them, and I’m happy to hear they turned out well with GF bisquick! I think almond butter would definitely work well. Worth a shot!
Made these for my daughter’s easter party at school today and they were a HUGE hit!! They are spool good
So glad everyone liked them, Kayla!
