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.

Where is the flour in this recipe?
Helen you would never know I owned a deli and bakery for 10 years lol
I reread the so simple recipe!
No problem! Enjoy x
Hi. Can I use almond flour instead of oats? Oats aren’t low carb that’s why I’m asking. Thank you.
I haven’t tried with almond flour sorry.
