Healthy Peanut Butter Brownies

Loyal readers know that I am entrenched in a friendly game of recipe tag with Susan at Organized 31. For the past month we have been going back and forth with new cookie recipes. We decided to move on to brownies and Susan’s first batch was a healthy makeover of packaged brownie mix. So, in response, I’m doctoring my own box of brownie mix and pairing it with one of my favorite brownie accompaniments—peanut butter.

I know, these brownies look ridiculously indulgent. My original, non-healthy, recipe is indeed decadent. However, with a few tweaks, this version has almost half the calories, 1/3 the fat, and less than half the sugar. The healthy version also boasts 4 grams of protein per brownie, and more calcium and fiber than the decadent version.

The Secret To Making Healthy Peanut Butter Brownies

The secret to “healthifying” the brownies is to substitute egg whites for the eggs and avocado for the oil. I replaced the peanut butter frosting that I usually make with butter, powdered sugar, and peanut butter with a lighter, fluffier version made from Fiber One 90 Calorie Instant Pudding (lower calories, more fiber and more protein than regular pudding mix), Cool Whip, and Jif Natural Creamy Peanut Butter.

  1. Thanks so much for sharing your post at the Pintastic Pinteresting Party. These look delicious and it is very hard to believe they can be healthy. I don’t think I had ever heard of substituting avocado for oil. Very interesting. Of course, my favorite way to eat avocado is to cut it in half, remove the pit, grab a spoon and dig in! Love it. Thanks again.

  2. 5 stars
    Those look amazing! Thanks for sharing this post on our Bloggers Brags Weekly Pinterest Party. I can’t wait to see what you share next week with us!

  3. I didn’t know Fiber One had pudding. A great way to sneak in avocados! I’d have to make it during the week when my son wasn’t there so he wouldn’t know what was in these brownies!

  4. I actually think the healthy version sounds better! I can’t wait to try this recipe and I’m pinning to my “Healthy” board. Thanks for sharing!

  5. I wouldn’t have believed these were healthy until I read the ingredients! Great list of ingredients and I love that they are “secret”!

    • Just make sure you really mash up that avocado. The riper the avocado, the better, since it will break down more completely. My son is very suspicious if he spies anything green in there!

    • Yes, you’re tagged, but don’t rush! I don’t know how many “healthy” brownie versions I’m going to be able to come up with.
