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!

What Are the 3 Ingredients You Need?

  • Old Fashioned Oats
  • Peanut Butter
  • Honey
3 Ingredient NO Bake Peanut Butter Oat Bars...SO easy, only 3 ingredients!

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!

    They tasted amazing but fell apart on us. We just put it in a bowl with icecream. Maybe I didn’t measure out enough peanut butter or honey. But tasted amazing and will for sure be making it again!!

  2. So simple and quick to make! I saw the comment about the old fashioned oats, so I pulsed mine a couple of times in food chopper. I heated the peanut butter and honey in the microwave. It pressed nicely into a baking dish and is now in the fridge for later. Thanks for sharing!!
