100-Calorie Protein Mug Brownie
What’s better than an ooey-gooey chocolate brownie fresh out of the oven? I’m thinking an ooey-gooey chocolate protein mug 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.
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
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!
Okay, that’s pretty much all ya need to know. As always, if you make this microwave protein brownie, tag me in your creation on Instagram. Enjoy!
- 1/4 C (60g) Canned Pumpkin*
- 1/2 scoop (16g) Vanilla Protein Powder
- 1 Tbsp (5g) Unsweetened Dark Cocoa Powder
- 1-2 tsp Granulated Sugar Substitute (optional)
- Mix the dry ingredients in a bowl or mug. If you'd like to easily remove the brownie from the mug after cooking, transfer the protein brownie batter to a second mug or bowl sprayed with nonstick cooking spray.
- Microwave for 1-1.5 minutes for a single recipe or 2-2.5 minutes for a double recipe. Depending on the size of your bowl, watch for overflow.
*If you're not a fan of pumpkin, you can sub unsweetened apple sauce or even go half and half with apple sauce and pumpkin to reduce the pumpkin flavor.
Each brownie has 1 WW SmartPoint (blue).

For Make Ahead Brownies
You can fill 4-ounce microwave safe jars with the brownie batter and refrigerate for 4-5 days. When you’re ready for a brownie, pop the jar in the microwave. You’ll likely need to play around with cook time as it will vary on the size of jar and amount of brownie batter you put inside the jar. (The 45-75 second range would be my guess.) I’ve not tried freezing them, but you could probably freeze and thaw overnight.
If you’re using smaller jars, you could use a piping bag or Ziploc bag with a corner cut off the get the batter in the jars.
