How to Make This Fudge Brownie Pie

Let’s quickly run through the components of this personal pie and touch on potential modifications, tips, and all that jazz.

The Crust

It doesn’t get any easier than this. The recipe calls for a ready made graham cracker crust from Keebler. I find these at Walmart, Target, and sometimes Kroger.

If you have trouble finding them or wanted to make your own crust, here are a few of my recipes that could work:

You could also go crustless and throw the fudge brownie batter in a ramekin for a few minutes at the same oven temperature. And if you’re really hungry, eat is straight out of the bowl. It doesn’t need to be baked!

The Protein Fudge Brownie Filling

Here are the dry ingredients you’ll need with a quick note on potential swaps:

  • vanilla protein powder
  • unsweetened cocoa powder (or omit and use chocolate protein powder – I just buy vanilla since I can make it chocolate but can’t go the other way)

Don’t want to use protein powder but still want a brownie. I recently did an experiment to test eight of the internet’s best recipe to find the ultimate healthy brownies recipe.

And the wet ingredients:

  • creamy peanut butter
  • unsweetened apple sauce (canned pumpkin, mashed banana, light butter, or more peanut butter would be worthy alternatives) 

The brownie batter should be thick but not too thick to spread. I highly recommend weighing ingredients using a food scale for accuracy. If your batter is too thick, you can add a bit more apple sauce.

Air Fryer vs Oven

While the recipe calls for baking in an oven, you could certainly use an air fryer for the same time/temp. Every air fryer is a bit different, though. So keep an eye on your crust in the first step to avoid burning it.

With either method, there aren’t really any food safety concerns in the brownie mix so you can slightly undercook the brownie for an extra gooey center.

Final Fudge Brownie Pie Recipe Notes

With any protein dessert, I always like to mention that every protein powder is different, unfortunately. If you’re using a different protein than the recipe calls for, you may have to tinker with the recipe to get it just right.

In the case of this fudge brownie protein pie, too dry means you probably need more peanut butter or apple sauce. On the other hand, if your batter is too runny, you may need more protein powder or less apple sauce. PEScience is a whey and casein blend, which means it’s a bit more dense and absorbent than whey on its own. 

Okay, that’s it! If you make this fudge brownie pie, take a pic and tag me on Instagram @mason_woodruff. Or you can join my free Facebook group and share it with the Proton Party.

Another home run! My 14 year old has been making this for the two of us, he has time on his lunch break from distance learning to whip it up and pop in the oven, then eat his lunch while it bakes & cools. It's quick, yummy & fudge, and doesn't taste like protein powder. Winning!

I had a full size reduced fat crust in my cupboard and decided to make this. I tippled the filling recipe and it still didn't have much filling but the taste was on point! I used PFC for my protein and under cooked it so it was nice and gooey!
