These 3 Ingredient No Bake Oat Squares Are Easy and Delicious!

Easy can not even describe these 3 Ingredient No Bake Oat Bars! I would say they’re simple to make, but “simple” is so over-used…by me especially…that I’m afraid you might not buy it. Regardless, they 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 Oat Bars are kinda-sorta not even that bad for you!

Oat Squares Quick and Healthy Snack Idea!

I know the word healthy is extremely overused, but the simplicity of the ingredients, plus the fiber and protein these contain make them a more healthful option in my house than a cookie. They’re a great option to have on hand for a snack or even a grab and go breakfast!

3 Ingredients for No Bake Peanut Butter Oat Squares

Add-In Ideas:

The great thing abut this recipe is that while they are perfect in their 3 ingredient simplicity, you can also add in other ingredients for flavor or health benefits.

  • Flax seeds. A tablespoon or two will add fiber, protein, and omega-3 fatty acids.
  • Coconut. 1/4 cup or so will add texture, flavor, and sweetness!
  • Chocolate Chips. Peanut butter and chocolate are the perfect combo!
  • Crunchy Peanut Butter. This will add texture when swapped out for creamy!
  • Raisins or dried fruit. 1/2 cup would be delicious!
  • Chia seeds. a few tablespoons will add high quality protein and antioxidants.

Tips for Making No Bake Peanut Butter Oat Squares

  • If your honey isn’t brand new it might be a little crystallized, which makes it hard to pour. BUT heating honey weakens the ingredients rendering the health benefits ineffective…so if you’re just in it for the taste you can heat it a bit. But if you’re looking for the good stuff that comes along with honey, heating it might not be the option.
  • Use Old Fashioned (or rolled oats). I find that they work for the texture and stability of these bars a little better. If you only have Quick oats on-hand, it will be fine, it’s just a texture thing. 
  • Use whatever kind of peanut butter you prefer! If you love Skippy, use it! If you like natural peanut butter, use that! It’s completely up to you!

Do You Need To Chill These Oatmeal Bars?

Chilling these bars is part of the process to aid in them setting and becoming firm. But do you need to store them int he refrigerator? You can! If you want your bars to stay extra firm, keep them chilled! If you allow them to come up to room temperature they will be softer, but also delicious!

Very sweet! Maybe I’ll try half honey next time but then I’d need more wet ingredients. What would you recommend?

It was extremely dry. I added all the correct measurements. It crumbled in my hands.

We had honey with lemon and I tried that instead of regular honey and it added a fruity tint to it. Didn’t have full confidence in the recipe because how could something so simple taste so good. But I’m definitely going to make this again. I’m obsessed.

I made these using crunchy peanut butter, half the honey, a little brown sugar, and a tablespoon of maple syrup but the mixture seemed a bit dry and crumbly, so I added 50% more melted crunchy peanut butter and I made balls out of them, instead of bars, as another person suggested. They turned out great. They are amost like an oatmeal peanut butter cookie. Next time I think I might add mini chocolate chips.
