If you’re looking for a healthy and easy treat to make, I definitely recommend trying these no bake oatmeal bars. They come together in just a few minutes and can be made with a stove or a microwave. The end result is chewy peanut buttery oat squares which store well and can be eaten for breakfast, snack or dessert.


  • Peanut Butter
  • Honey
  • Rolled Oats

These bars are just 3 wholesome ingredients which is why they make such a healthy treat.

Peanut Butter

This recipe works with both natural or processed peanut butter. I prefer using natural peanut butter to keep the bars healthier. I recommend using unsweetened peanut butter because the bars are sweet enough from the honey.


If you don’t like peanut butter, you can also substitute with other nut butters but I do think the peanut butter gives the oat bars more flavor since many other nut butters have a milder flavor.

Stove or Microwave

The peanut butter and honey need to be first heated and mixed together. This can be done over the stove using the double boiler method or in the microwave. I used the microwave because it meant one less pot to wash.

Texture of No Bake Bars

The bars have a chewy texture from the oats. Because they are not baked, they do have a looser crumb and will fall apart a little when you bite into one. But they are still sturdy enough to cut into bars and enjoy.

  • 1 cup creamy natural peanut butter unsweetened
  • 1/2 cup honey
  • 3 cups rolled oats


  • Line the bottom of an 8 inch by 8 inch (can also use a 9 x 9) baking pan with parchment paper.
  • Add peanut butter and honey into a large bowl. Place into microwave and heat at 30 second intervals, stirring in between, until the two ingredients are melted and smoothly blended together. You can also do this on the stove using the double boiler method.
  • Add rolled oats. Stir until evenly combined.
  • Spread evenly into prepared pan. Apply some light pressure across the surface. Place bars into fridge to set (at least 1 hour). Cut into bars with a sharp knife. Store uneaten bars at room temperature or in the fridge.


  • Recipe slightly adapted from Cookie & Cups
  • You can use processed peanut butter instead of natural. 
  • You can substitute peanut butter with other nut butters but the bars won't have as much flavor.

  1. These are easy and delicious! Love that it uses minimal ingredients as well. 

  2. Can you use light Karo syrup?

  3. You did not give the exact amount of the ingredients. Need to know exact amount of peanut butter, honey and rolled oats on the No Bake Oatmeal Bars. Thank You

    • The ingredient amounts are listed in the recipe card at the end of the post before the comments section.

  4. Hello,thanks for sharing what you do lovely lady.
    Was wondering would it b o k to use instant oats.?

    • We haven’t tried it with instant oats. The only issue might be that the bars won’t hold together as well, but we can’t say for sure without testing it.

  5. I adeed salt, since my peanut butter was 100% peanuts, no salt. Great, easy recipe

  6. Can I add raw cacao powder? If so, how much? Thank you.

  7. Hi Kirby, can I substitute honey with golden syrup, our honey in south africa is very expensive.
    Also can I use normal oats?

    Looks like a great recipe. Can’t wait to make it.

  8. Hey Kirby, These are Amazing! Only the honey & p-nut butter achieved that gorgeously appetizing golden color? I am very willing to try these once I get the honey-although, I plan on using Sun Butter instead of P-nut butter. Hope mine look as yummy as yours do.

    • the recipe will work with sun butter but the color won’t be the same because the sun butter color is different than peanut butter

  9. Is there an alternative to nut Butters? (daughter highly allergic)

  10. Looks Yummy!

  11. I tweaked this recipe by adding coarse chopped cashews About 1/2 cup.

  12. Made these they are good. Quick protien.

  13. I literally just made these – barely put them in the refrigerator and had to comment. I nipped a bit while stirring and lawd al’mighty great recipe. I didn’t make any changes – didn’t need too. The recipe is great as is. Thank you!

    Would you mind if I posted the link to your recipe on my website? 

  14. Can I use a non- caloric sweetener for the Oatmeal bars?

  15. Sorry, I meant cashews

  16. I make my protein peanut balls like this recipe, I add coconut flakes, chopped chews, vanilla chips & choc mini chips, I usually eat one after a work out & they hit the spot, delicious!!??
