3 Ingredient No Bake Peanut Butter Oat Squares

3 Ingredient NO Bake Peanut Butter Oat Bars...SO easy, only 3 ingredients!
funsweets

These simple 3 Ingredient No Bake Peanut Butter Oat Squares can be thrown together in minutes. Use all natural/organic ingredients, if you prefer, for a healthier version! Either way they are simple are delicious.

Easy can not even describe these bars.

And simple is so over-used…by me especially…that I’m afraid you might not buy it.

But I promise ya.

These are the simplest, easiest, no brainiest bars ever to be.

There are literally 3 ingredients, no baking…only measuring. And you only have to measure 3 things, so…

PLUS, these 3 Ingredient No Bake Peanut Butter Oat Squares are kinda-sorta not even that bad for you!

 

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.

3 Ingredient NO Bake Peanut Butter Oat Bars...SO easy, only 3 ingredients!

See..3 ingredients…

Also, trying to get honey out of a huge container when there isn’t much left is pretty much the worst day of my life.

But I overcame.

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!

3 Ingredient NO Bake Peanut Butter Oat Bars...SO easy, only 3 ingredients!

So yep. 3 ingredients!

Oh my goodness, those honey containers from Costco will be the death of me! So frustrating, especially cause the honey gets firm so fast. I will definitely be using a fresh container of honey for these babies!

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.

Raw honey takes longer to solidify…and simply soften by putting in hot water for 10 or 15 minutes.

They get hard because they are using corn syrup as a filler.

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.

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.

Put container in microwave and heat about 30 seconds, this should soften the honey.

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!!

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!

I just can’t get over how easy these bars are!! They looks like they would take hours! And 3 ingredients?! Can’t beat that! They looks so good!

There has to be a better way to package honey, it’s the worst getting out of those squeeze bottles! This recipe seems totally worth the effort, so simple and delightful!

are these crunchy or chewy?

Guest
May 9, 2014 2:10 pm

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.

Guest

That is exactly what I just did at 10:49. I hope the natural peanut butter will set up since there’s no baking involved. :)

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?

Guest

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!

Lara
May 30, 2014 3:46 pm

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.

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.

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.

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,… Read more »

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

Guest
Terri
August 11, 2014 5:14 pm

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.

Guest
Terri
August 11, 2014 5:20 pm

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.

Too much peanut butter. It made the bars really dense. Some advice for the person making this: don’t put 1 cups of peanut butter.

I make with organic oats, organic maple syrup, organic peanut butter & add chopped peanuts, pecans, almonds or walnuts.

Also dried fruits minced is good too just make sure it’s real dried fruit & not the sugar and chemical dried fruit. I use maple syrup because I’m not a fan of the taste of honey.

I am going to try these with almond butter next time and maybe cashew butter the next to see how they taste. Keep on cooking;)
