What is 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.

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.

These simple, low-fat peanut butter oatmeal cookies require just 4 simple ingredients. Satisfy your next cookie craving with these tasty, wholesome little treats.




  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 applesauce can be substituted with additional banana.

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. Add chocolate chips to make them more of a treat.
