About Powdered Peanut Butter

To make these peanut butter cookies low in fat, I used powdered peanut butter instead of regular peanut butter. Powdered peanut butter is essentially peanuts have have been pressed to remove much of the oil and fats. This leaves the taste but reduces the fat and calories, leaving you with a peanut powder that can be reconstituted in water.

Peanut butter is more or less my favourite food but since I’m tracking macros right now it’s pretty hard to include much of it in my diet. In comes P2B, one serving provides just 45 calories with 5 grams of carbs, 5 grams a protein and 1 gram of fat. Sounds too good to be true, right? Well, it kind of…it’s by no means real peanut butter but it gets me by and I think it’s a good ingredient to have on hand for peanut butter snack attacks.

I often use it as a replacement for peanut butter, especially in sauces, and I also just mix it with water to eat as a spread or dip.

Healthy Peanut Butter Oatmeal Cookies Recipe

These (key word: low fat) cookies definitely taste like they’re healthy. I mean, you can only ask so much from 75 calories!! These are not a big, beautiful, decadent peanut butter oatmeal cookies however, those big, beautiful, decadent peanut butter oatmeal cookies can be upwards of 400 calories each, so they’re not something I include in my diet on a daily basis. I wish.

That being said, these are enough of a treat to satisfy my sweet tooth and cookie cravings. You can always add dairy-free chocolate chips if you want them to feel a bit more like dessert!

The Simplest Cookies

I sometimes make these cookies with just oats and banana. If you’d like to try that, all you need are 3 bananas and 2 cups of oats. Mash the bananas, stir in the oats and bake for around 10 minutes at 350. Today, I felt like an extra special version of those so in went powdered peanut butter for a low fat version of my Flourless Peanut Butter Banana Oatmeal Cookies.

Customize These Cookies

If you want to switch these cookies up, they’re very flexible so you can easily play around with different flavour combinations. The banana can be replaced with pumpkin puree or even mashed sweet potato, as can the applesauce. I’ve made a carrot cake version as well. You can find these variations here:

Try different combos and see what you can come up with! You can get creative with other add-ins too. How about pumpkin puree with cinnamon and walnut, or grated carrot with nutmeg and ginger, or chopped pecans and raisins. Anything goes!

These simple, low fat peanut butter oatmeal cookies require just 4 simple ingredients. By using powdered peanut butter instead of regular peanut butter, each cookie is just 75 calories! Satisfy your next cookie craving with these tasty, wholesome little treats.



Optional Ingredients:


  1. Pre-heat oven to 350 degrees.
  2. Place the mashed bananas in a bowl and stir in the applesauce to combine.
  3. Add the oats, powdered peanut butter and salt. Mix well.
  4. Prepare a baking tray with parchment paper or a silicone baking mat, or very lightly spray with non-stick cooking spay.
  5. Drop 12 spoonfuls of the dough onto the baking tray, pressing down a bit to form cookies.
  6. Bake for 16 minutes until golden brown, do not overcook. If they seem slightly underdone when you take them out, that’s about right.
  7. Let cool on the pan.


  • The banana can substituted with additional apple sauce, mashed sweet potato or pumpkin puree. Alternatively, the applesauce can be substituted with additional banana. These cookies are pretty flexible so play around and find a combination that works for you!
  • I added a few drops of liquid stevia for extra sweetness but they’re still quite sweet without it so it’s totally optional. Powdered stevia also works if you don’t have drops, just taste the batter and adjust the sweetness from there. The sweetness will also depend on how ripe your bananas are, the riper the banana, the sweeter the cookie!
  • These are low-calorie, low-fat cookies and they definitely taste like it. If you’re looking for a decadent treat, this isn’t it but if you’re after a simple, healthy cookie that will satisfy a craving while easily fitting into your nutrition plan, these are perfect. You can add chocolate chips to make them feel more like dessert if you like.
