These 3 ingredient peanut butter cookies need to be on your weekend baking list.  They have 7.5g protein per cookie, so great for a snack that fills you up!

They couldn’t be simpler to make. Literally mix some smooth peanut butter with a little maple syrup and oat flour, and bake for 12 minutes. They make the best power snack!

There are many variations of these cookies out there, but I think mine have the least sugar I’ve seen.  If you do have a particularly sweet tooth, add a little bit more maple. However, I would suggest, you try the recipe first – I think you’ll be pleasantly surprised how good they are!

Give them a try and let me know what you think in the comments below.

What do you need to make 3 ingredient peanut butter cookies

  • Organic Smooth Peanut Butter
  • Oats or Oat Flour
  • Maple syrup

Recipe Tips

  • I bake for 12 minutes for a nice crisp texture, without being too hard.  If you want a slightly harder bite, bake a couple of minutes more.
  • I use a very runny peanut butter to make these. If your nut butter is a little harder, you may need to add some water or some more peanut butter as you combine. This will give you a softer consistency. The consistency should be quite soft before you bake, and come together easily.
  • I use whole oats that I blend into a flour. If you are using ready-ground oat flour, only use about 3/4 cup, rather than the whole cup, as stated in the recipe.
  • You can use any oats for these cookies – you are grinding into a flour anyway
  • They will last for 3-4 days in a sealed tub, and a little longer if you store in the fridge.

    Hi. Can I use almond flour instead of oats? Oats aren’t low carb that’s why I’m asking. Thank you.

    Can I use honey instead of maple syrup?

      I haven’t tried. Taste-wise it will be fine but I don’t know whether it will be too sticky. I’d say give it a go!
