What’s better than an ooey-gooey chocolate brownie fresh out of the oven? I’m thinking an ooey-gooey chocolate protein brownie with 100 calories and 13 grams of protein that’s ready in one minute!

Since I first published this recipe, it’s gone on to be one of my most popular recipes. And for good reason. It tastes amazing, has the texture of a real brownie, and is unbelievably easy to make. Watch the video below to see just how simple it is.

Note: I doubled the recipe for the video. 

Microwavable Protein Brownie Ingredients

Most readers love this protein brownie straight out of the box, but I’ll tackle some common ingredient questions below.

What can I use instead of pumpkin? 

Another great thing about this protein brownie is that it’s highly customizable. If you don’t love pumpkin, there are lots of potential swaps:

  • Unsweetened Apple Sauce
  • Mashed Banana
  • Light Butter (lower carb option)
  • Avocado (lower carb option)
  • Cooked and Mashed Sweet Potato (or any starchy carb puree)

I’ve included notes on using half pumpkin and half apple sauce in the recipe card’s notes section, as well as a peanut butter banana protein brownie variation.

Additional Sweeteners and Toppings

Depending on how sweet your sweet tooth is, you can add stevia or zero-calorie sweetener to either recipe, but I find it’s sweet enough without it.

As for toppings, fat-free whipped topping is a great way to trick your mind into thinking brownie with ice cream since the whipped topping melts a bit. Placing a few chocolate chips on top right out of the microwave will give a melted chocolate, extra gooey consistency without adding many calories. Just be sure not to go chocolate chip crazy here!

And I’d be remiss if I didn’t recommend using a half cup of a lower calorie ice cream like Edy’s Slow Churned Vanilla. Yum.

My Choice of Protein Powder

You can use any protein you’d like. I find that a vanilla protein with added cocoa gives a more authentic brownie taste, but you could just use chocolate protein and omit the cocoa if you like. As for protein recommendations, I go with Optimum Nutrition Gold Standard Whey and/or Dymatize’s Whey or Elite XT blended protein. They’re reputable brands that have been around forever.

Update: A new addition to my recommended protein list is PEScience Select Whey and Casein. It’s what I use for most of my recipes on my second blog, Mugs for Muscles, and it’s the protein powder I used for the video for this recipe.

You'll love this ooey-gooey microwaveable chocolate protein brownie that's ready in one minute and packs 13 grams of protein into 100 calories.

The macros in both recipes are with Gold Standard Whey. If you’d like to learn more about the different types of whey protein and how to find the best value for protein, read this article.

How to Avoid A Tough or Dry Protein Brownie 

Since there are a lot of moving parts in recipes with protein powder (different types of protein, volume differences in scoops, scooping vs weighing accuracy, etc.), there’s always a chance you’ll end up with a tough or dry finished product. I’ll include a few ideas to combat this below:

  • Use whey concentrate or a blend of proteins that’s not super lean like whey isolate (the extra carbs/fat goes a long way)
  • Slightly reduce the amount of protein powder used
  • Increase fat sources or faux fat sources (i.e. pumpkin, mashed bananas, sweet potato, avocado, unsweetened apple sauce, coconut oil or processed coconut flakes, etc.)
  • 14 grams of light butter only has 50 calories and changes lives
  • Slightly increase liquid ingredients
  • Reduce cook time
  • Add moisture after cooking via whipped topping, ice cream, or fruit reductions

Life’s too short for dry protein treats. I hope this helps!

  • Mason, I love this recipe but I was wondering if we could sub something in place of the protein powder to reduce the protein/calorie content of the recipe? I’ve tried 7g of coconut flour instead of the 15g of protein powder but it is simply does not work very well at all. Absorbs too much moisture from the applesauce/pumpkin and does not microwave very well at all. Any other suggestions?

    • Hey Ryan, I’m happy to hear you’re enjoying it! I’m thinking the coconut flour might work if you increase liquid ingredients. Maybe 2-3 Tbsp of almond milk or an additional 1-2 Tbsp of pumpkin or apple sauce to balance out its absorbency. Beyond the coconut flour, you could try an all purpose flour, though that may defeat the reducing calories goal. Looking at my birthday mug cake recipe (https://masonfit.com/high-protein-birthday-cake/), it looks like 1 Tbsp of coconut flour goes a long way there. So maybe you could try as little as 1-2 tsp of coconut flour in place of the protein here. Or even cut the protein powder in half and add 1 tsp coconut flour. Just some ideas – let me know how it goes!

  • This has been my breakfast for like … a month (?) and I’m still not getting bored of it! It’s unbelievably fluffy, extraordinarily fast and easy to do. I mean, this is literally the reason I wake up every single morning, I swear! 🙂

  • Hands down the best brownie I ever had. I was skeptical about the pumpkin. But omg, it was amazing and cured my sweet tooth.

  • Hey Mason! I absolutely love making this recipe and I probably make it 3-4 times a week for my night time snack. I love how convenient it is along with it being so low calorie compared to other brownies out there. I love following your two pages on Instagram and love trying different recipes. If anyone is reading this, I would definitely add this to your list to make. It is sooo good, trust me!!

  • This brownie is the best thing on earth. I eat it ALMOST every single night. This is the greatest thing on earth. ON. EARTH. I put ice cream on top of it, sometimes it’s just some PB and choc chippies sprinkled on top. Sometimes I’ll put FF cream cheese on top and then load it down with some Oreo O’s. I ran out of cocoa powder last week (sssss’sad day) so I just left it out and it was still sooooo flippin good. The macro gods are rejoicing right now at this brownie.

  • Hands down what I make when I need a chocolate fix. Love making this and my daughter loves this healthy alternative to chocolate cake too!

  • This recipe is amazing! It is so easy and quick! It is hard to believe how good it is for you based upon how it tastes! I am thinking of using it to make chocolate covered truffles.
