Low Calorie Brownie Muffins

Low calorie brownie muffins. If you were to combine moist chocolate cake, and a brownie you would get these brownie muffins. They are so good, a perfect treat, and less than 100 calories per muffin.

I actually had trouble coming up with what to call these, I knew they were good and that I wanted to share them, but I was unsure what to exactly call them. They use brownie mix so I knew I wanted to include brownie, but they do not exactly have the texture of a brownie.

What I mean by that is that these brownie muffins are moist and taste more like a cake than a brownie, but they still have some brownie flavor to them. So all in all, they taste like a moist, chocolate cake, with flavors of brownies! Does that make sense?

Let’s get into what you need to make these low calorie brownie muffins:

  • Liquid Egg Whites: I recommend using the egg whites from the carton, but if you use whole eggs and remove the yolk you will need around 2 eggs.
  • Vanilla Protein Powder: I typically always bake with PEScience. In my opinion vanilla is the most versatile, and this brand of protein bakes the best!
  • Pumpkin Puree: You would be surprised how well pumpkin puree replaces ingredients like butter, and oils, aka higher calorie items!
  • Brownie Mix: I used Pillsbury brownie mix, you do not need the entire bag, you can save the rest for other recipes like my Cosmic Brownies.
  • Flax Milk or Dairy Free Milk: I am a big fan of dairy free milk, mostly because of the flavor, but also because of the calorie count. I never really liked dairy milk much anyway, plus save the cows! 
  • Unsweetened Cocoa Powder: This is important to add more chocolate, fudge flavor! 
  • PB Fit Peanut Powder: Oddly enough you cannot really taste this, but it adds a tad of sweetness and a bit more of protein, you can replace this with more protein powder if you would like, I just am unsure if the protein powder taste would be more prominent.
  • Salt, Baking Soda, and Baking Powder: You will need all three of these, these are fluffy and moist muffins, I am telling you!

So now that you have seen all the ingredients, let me reiterate the fact that you cannot taste the pumpkin, or the peanut butter powder. And hopefully that is not a bad thing in your mind because these are chocolate brownie muffins, not peanut butter pumpkin muffins!

Another great thing about these brownie muffins are that they are low calorie, they are only 97 calories a piece, and they are the size of a large fluffy cupcake! Each muffin is also 5 grams of protein, the perfect nightcap.

Frequently Asked Questions:

How long do you bake brownies in cupcake tins?

The texture of these brownies are more cakey. You want to make sure that you do not overbake these. The baking time for this dessert is 18 minutes at 350 degrees

How do you get brownies out of mini muffin tins?

The best practice for baking and not having the dessert stick is to always line the bottom with parchment paper, you do not need to line the sides, just the bottom. It works every time.

Can you put brownies straight in the fridge?

No, but make sure that you keep the brownies sealed in an airtight container so they do not dry out. I actually prefer to store them in the refrigerator just because I do feel like it keeps them fresher, but it is not necessary. When I want to eat one I just warm it up in the microwave for 15-20 seconds!

Do eggs make brownies cakey?

Eggs are not the main component in making the brownies fudgy or cakey, the fat content in the brownies will make them more fudgy. If you use more flour, baking soda, baking powder, and salt they will rise and be more cakey.

Are undercooked brownies safe to eat?

If there is raw egg in the brownies and they are undercooked they will not be safe to eat. With that being said, make sure that you do not overbake these brownies or they will dry out, the toothpick should come out clumpy when inserted.
