I’m certainly not going to call them healthy…because there are health police out there who like to assure you that Peanut Butter from Skippy isn’t so health-ful.

But in my world, these are the perfect treat for my kids after school…full of fiber and protein, plus the honey makes them sweet and delicious.

So yeah. Try them.

Tips on Making No Bake Peanut Butter Oat Squares:

I heated my honey and peanut butter together so they would be smooth. You can totally do this in your microwave too.

Then just mix in the oats. Also, yes, you could use quick oats, but they are cut and smaller in size (hence why they cook faster), and I prefer the large whole oat in these. Whatever.

Kinda pretty, yes?

Then press the mixture into a lined 9×9 pan, that is sprayed lightly with cooking spray to prevent sticking…

Let the mixture set up. I popped mine in the fridge (and actually stored them there too to keep them firm). Then cut into bars!

Again, if left at room temperature they will soften a bit, so I like to keep mine chilled…but if you prefer them softer and gooier go for it!

Hi! I’m Shelly and I’m an addict. Of the buttercream sort. I started this site a few years ago as a way to justify my sugary, buttery obsession with desserts. It has worked out well for me so far, because as it turns out you guys all love sugary, buttery desserts too! It feels good to know you're not alone, doesn’t it?

      Meriem, I just saw this and wanted to share that you can soften a container of honey by putting it in the crockpot, fill crockpot with water to height of honey, turn on low and just let it go until the honey is liquid again. Doesn’t matter if the container is taller than the crockpot — leave the lid off. Works like a charm.

      1. Laura

        Actually, pure honey can and does go hard. My grandpa used to keep bees and my dad still has honey from it; it’s more than 20 years old, and it’s hard.

      2. Bobbie

        TOTALLY wrong! No corn syrup in most honeys. I buy mine straight from the bee keeper and it does crystallize. How fast it crystallizes depens on the amount of glucose in the honey. Some people prefer crystallized honey. 🙂 Most stuff can be googled for the answer so try that next time!

    2. Janel

      Raw honey does go “hard”. It becomes crystallized. That’s a good thing. Means it is raw. Store honey does not because its pasteurized to death! You can set your honey in hot water or let the hot water run on the bottle each time you use it and it will go back to smooth. My husband and I are beekeepers.

        1. Marianne

          I was wondering that myself. I make a facial exfoliant using honey,lemon,sweet almond oil and granulated sugar. Honey has anti microbial properties,lemon is an astringent,the oil moisturizes and the sugar provides the exfoliant. (Recipe came from Cooking Light magazine years ago) If I have to reheat the honey,am I loosing that benefit??

      1. Becca C.

        Not a good idea, as the bottles typically are plastic… And will melt, releasing plastic toxins. But glass also gets extreme hot as well.

    3. Becca C.

      You can also turn the container upside down, once you get the honey softened up again, and the honey will drip to the tip, making it easier to get it out. I usually put the honey upside down in a mason jar. I do this with other sticky items (agave) in my cabinet too. 🙂

    4. Deena

      I buy mine from Costco when l go to see my daughter or l get her to bring some when she comes.Because I’m a Sam’s member and l have the same problem with Sam’s honey It’s firm when l buy it.l went back to Sam’s and a guy said It’s ok just cut the bottom open and put it in a jar.They have got so much honey at Sam’s that l have been getting it at my daughter’s Costco for about 15mos. HONEY TURN TOO SUGAR.If you use it for health reason you not to heat it.lhad to heat mine too get it out.l live in Alabama &My daughter live in Richmond Va.

  1. Shannon @ Bake.Frost.Repeat

    Wow. These look great. I’m totally making them this weekend. I think I found something my incredibly picky 5 yr old will eat!

  2. Heather

    Bless you!!! I am off refined sugar this week, so I haven’t had a treat of any kind since Saturday (this is BIG for me.) I can totally do these!

    1. Sherri

      You can also try 1 cup of peanut butter, 1 cup of sugar and 1egg for gluten free peanut butter cookies. Bake at 325* for 7-8 min. Delicious!!

  3. Monica

    Yay!! A dairy-free recipe! I often adapt many of your recipes to make them dairy-free (which is NOT always an easy task!!), so I’m excited to try this one–sans-adaptations!!

  4. I have been craving rice krispie treats lately and these look so gooood! Plus they’re healthier than krispies, right? 😉
    Tonight we will have them for dinner!
    Well, maybe after dinner….

    Shelly, btw, I have a worldwide giveaway with 2 winners of the cutest lil bee salt/pepper shakers to honour Mother’s Day and benefit the effort to save the bees. Please stop by my blog when you get the chance. Good luck!

  5. Haha. The health police. I feel like I can never post anything with regular peanut butter. It has to be natural because I know even when I post a warning saying, “This recipe won’t work with natural!” people will make it with natural anyway and then be unhappy with the results. That’s because natural sucks for baking. That’s the end of my peanut butter rant. 😀

    And love that these are no-bake! This is something I’d make at 11:49pm and then not even bother forming into bars. A spoon works well enough for me.

    1. Marianne

      I’m so sorry!! Didn’t mean to hit the “thumbs down” button!! Purely accidental! I just wanted to if using natural PB was the reason mi e did t come out well? It’s all I had. I did add melted coconut oil,but still did t help….?

  6. Darlene

    Has anyone tried adding dark chocolate chips to this? If so, would you melt them first along with the peanut butter and honey or mix them in whole with the oats? Or would melting and drizzling along the top at the end work best?

    1. Trish

      I made mine with almond butter instead of peanut butter and I pressed chocolate chips and chopped pecans into the mixture before putting them in the refrigerator to set. Can’t wait to eat them!

  7. Lara

    Yum! Just made these and I can’t stop eating! I added a few extra things I had on hand to health them up even more… On the softened PB honey stage I added a scoop of protein powder and scoops of both chia and flax seed, as well as some Cacao powder for a little chocolate sensation. Also I did half honey and half melted coconut oil for the honey part, and it came out perfect with a nice hint of coconut! They are so delish and guilt-free! Will definitely be adding these to the regular rotation.

  8. Kali

    I just made this because I love the ingredients, but when combined…. not so much. I think it’s the texture I’m not liking and it’s very dense.

  9. alivia

    This recipe is very tasty.

    I don’t know if it’s because I used a different brand of peanut butter (used Peanut Butter & Co) than you or what it is, but my honey/peanut butter mix did not cover 3 cups of oats, it only held about 2 and 1/8 cups of oats. Neither did it get that nice gooey look like yours has got.

    In the future I may try adding coconut oil like “Lara” said in the comments here.

    I also used old fashioned oats. Yum.

    1. Shelly

      Not sure! It seems like it would, but syrup is a little thinner than honey. Let me know if you try it! Maybe just use a little less!

  10. Heather

    Perfect! We are experiencing extreme heat these days in iowa, and I’ve been trying to find a no bake peanut butter bar recipe to fill a craving, but they all call for more butter than PB, and tons of powdered sugar, neither of which I keep on hand! I used natural PB, as this is what I usually use, so some of the healthy police might be ok with it (though who wants to be worried about that when it comes to dessert?), but I DID proceed to cover the whole thing in melted dark chocolate…

    Ran out of honey, so used maple syrup to complete it (prefer it’s flavor anyway)…seems to work. Also had oat flour on hand, so used half oat flour, half whole oats, which had creatd kind of a Reece’s peanut butter cup feel…if you like that sort of thing. Thanks so much for providing!!!

  11. Inga

    Hello!
    Thanks for the recipe! I have tried it, but something isn’t right. Can you maybe, please, write amounts of ingredients in grams? 🙂

  12. Terri

    Just an alternative–use toasted oat flakes for an even more delicious treat and add almond butter and toasted almond slices for an even better version. One caution–almond butter is runnier than peanut butter so you may have to use less than the recipe calls for.

  13. Terri

    BTW–for those complaining about the Costco honey containers–save a few jars from whatever, clean well and use for the honey. They are much easier to liquefy the honey in and you don’t have to worry about plastics-chemicals leaching into the honey when you try to warm it up. I am trying bit by bit to use less plastic in my home because of all the negative consequences–the reliance on petroleum to create the containers, the problems with recycling them, the endocrine and hormone disruption they cause and all the other problems associated with plastic in the environment.

    1. Cup to Gram Conversions

      Do the Math
      1 ounce = 28.34 grams

      1 pound = .453 kilograms

      1 g = .035 oz

      1 kg = 2.2 lb

      1 fluid oz = 29.57 milliliters

      Measuring Spoons
      1 Tablespoon = .5 fluid oz or 14.79 ml

      3 tsp = 1 Tablespoon

      4 Tablespoons = 1/4 cup

      16 Tablespoons = 1 cup

      More Quick Conversions
      1 c chocolate chips = 152 g

      1 c cocoa powder = 128 g

      1 c walnuts, chopped
      = 122 g

      1 c walnut/pecan halves
      = 99 g

      1 c shredded coconut
      = 71 g

      1 c solid shortening, e.g. Crisco® = 205 g

      1Tbsp baking powder
      = 12 g

      1 Tbsp salt = 18 g

      How much does a cup of butter weigh? Well, let’s see…

      Butter
      If you know a cup of butter weighs 8 ounces, you could do the math yourself:

      1 ounce = 28.34 grams, so one cup of butter weighs 227 grams.

      1/4 cup of butter = 57 g
      1/3 cup of butter = 76 g
      1/2 cup of butter = 113 g

        Just buy a set of ‘cups’ to measure next time, that’s what I had to do for all my american bakes in the end, got sick of doing math everytime I wanted to try a recipe!
