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.

Ingredients:

  • 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 (12 ounce) M&Ms (I used regular–but now I’m thinking peanut butter M&Ms would be W-O-W)

Directions:

  1. Preheat oven to 325 degrees Fahrenheit. 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–these peanut butter bars 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!

  2. Hi Rachel!

    Probably a silly question, but I’m not the world’s best baker… do you know how I could add to the amounts to adapt it to a 9×13 pan and maintain the thickness of the bar?

    Thank you!

  3. I always have a container of these! My children and husband insist. And I also throw some of the mini Reeses cups on top and they’re even better!

  5. The picture here looks amazing. But I made these and they are just okay. Not bad. But not great. Just meh. I added a bit less flour because I was worried they would be stiff and dry with all that flour and I took them out 10 minutes early, but they were still a bit stiff and dry so if I had added all of that flour and cooked it for the directed time then it would have been worse. Overall it’s an okay recipe, but I wouldn’t make them again.

  6. I have made this recipe 5 times i just love it. This is my new go to recipe. I have been asked for the recipe and already have a birthday request in for this to be made. I make it with either mini m&ms or mini choc. chips. And i also under bake it a few minutes. Thanks for the recipe.

  7. Can I use regular flour instead of Bisquick?

  8. I just made these exactly as the recipe says – it was horribly dry. I only baked it 35 minutes. It was basically inedible. I dont know what went so wrong but it was awful.

  9. These tasted good right out of the oven. A little dry, but good.I covered them, and came back the next morning.The already dry recipe had hardened into something like cement. They are impossible to cut, and we can’t get them out of the pan. And something happened to the taste and they are like sawdust. I followed the recipe exactly, so I honestly don’t know what went wrong here after reading all these great reviews, but… It was bad. All around disappointing, which is sad because I was really craving some peanut buttery goodness.

  10. Has anyone tried using a brownie pan like pamper chef’s brownie pan with this recipe? 

  11. I just tried this and it was super simple! I loved that it only had 5 ingredients and the kids could help make it. They were a little sweet for my liking but the kids and my husband’s coworkers gobbled them up. Next time I will try them with peanut butter M&Ms. What would you think of me sharing this on my blog?

  14. If I use a 9×13 pan, how long do you think I should bake them for?

    • I’ve never baked them in a 9×13 but I’d decrease baking time by probably 10 minutes and check on them to see if they are golden brown. You want don’t want to overbake them.

  17. Does the dough come together cohesively or is it crumbly? I want to know if the baked cookie bar is moist? Thx they look yummy.

  18. I love the recipe but I can a question about the baking mix? Can I use regular all-purpose flour as well or is it just baking mix like pancake batter?

  19. When I cut through these, They seem really raw in the middle. Are they supposed to be that way ?? Left them in for exact time. Looked fully baked on outside. Shame to throw whole batch out.

  20. I made these in a 9×13 pan and they turned out great! Just a little thinner than they would be in the 9×9. So good!

  25. Made these for my daughter’s easter party at school today and they were a HUGE hit!! They are spool good :)

  26. 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!

  27. 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.

  28. 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!

  29. 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 :)

  30. 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!

  31. 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 :)

  32. Thank you I will :)

  33. 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!

  34. 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!

  35. Just made these and they were amazing. Thank you so much for the recipe!!!

  36. 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!

  37. 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!!

  38. 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! :)

  39. Can the “all purpose baking mix” be the just-add-water kind? What do you recommend? These look fantastic!

  40. These are wonderful! So easy to make. I just mixed up a batch for a Christmas dinner tonight. Finally a different, and easy recipe!

  41. 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!

  42. 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!

  43. 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.

  44. I made these with flour and peanut butter M&M!s and they are amazing!!!! Thank you for sharing the recipe!

  45. My mouth is salivating just thinking about these. Stop posting such great recipes! I feel fat already! lol.

  46. These look unbelievable. I’m with you – just as excited about a 5 ingredient recipe! Wahoooooooo!

  47. 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!

  48. YUM indeed! Those look dangerously good.

  49. How do I love thee…let me count the ways! Okay, no more math but I am going to have to make these!

  50. 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!

  51. 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.

  52. I can handle 5 recipes when it comes to baking!! Yum!

  53. 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!

  54. using the traditional m&ms makes them so bright and colorful! Love :)

  55. Im 5 ingredient sold! These look awesome!

  56. Wow! This looks amazing and is so simple. Love!

  57. Want to send some my way? :)

  58. These look great! Love the ease.

  59. LOVE these! Great, easy dessert :)

  60. 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:-)

  61. Simple and delicious looking, great recipe!

  62. These look incredible–it seems too good to be true that I only need five things to make them! Or perhaps just too dangerous… :)

  63. 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!

  64. Thanks for the math lesson. :) Those M&M’s are popping out of your photos! I want, I want, I want!

  65. The 8 year old in me just got very excited; I use to eat these everyday as a kid. Yumm!!!
