5-Ingredient Simple Protein Cupcakes

One of my biggest objectives in recipe development is simplicity. I often joke if a recipe’s ingredients can’t be counted on one hand, it’s too complicated. That’s hyperbole, of course, but these simple protein cupcakes definitely pass that test.

Straight out of the box, this cupcakes recipe has 99 calories, 6 grams of protein, 14 grams of carbs, and 4 grams of fat per protein cupcake. I’ve included lots of tweaks and modifications for certain ingredients and ways to make these protein cupcakes even more macro friendly. Rest assured those tweaks are fairly simple as well, with one option being a 2-ingredient protein frosting.

With four ingredients and one bowl, you'll have protein cupcakes in the oven in minutes. Each cupcake has 6 grams of protein and only 99 calories.

How to Make Simple Protein Cupcakes

Two of five ingredients on the list are pretty straightforward—eggs and almond milk (or any liquid). The other three ingredients have potential substitutions that I’ll touch on below.

Sugar Free Cake Mix

Like my glazed cake rolls, this recipe calls for Pillsbury sugar free yellow cake mix. I buy this ingredient from both Kroger and Walmart in my area. If you’d like to save some time searching, click here to use their find a store tool. I already have the product loaded for you ’cause I love ya.

If you’re looking for an alternative option that uses a different sweetener, I’d highly recommend Swerve’s cake mix. I haven’t tested it with this recipe, but I would recommend swapping it gram for gram with the Pillsbury mix.

And if you’d like to skip the cake mix altogether, check out my birthday cake protein cupcakes. They’re made from a combination of coconut flour, all purpose flour, and protein powder. You’ll need a few more ingredients than these simple protein cupcakes, but they’re super tasty!

Protein Powder

If you’ve tried my birthday cake cupcakes above, you might notice this recipe calls for a different protein powder. I’ve tried lots, but I think I’ve narrowed my favorites down to the protein in this recipe (PEScience Whey and Casein) and the Dymatize 100% Whey I used in the birthday cake cupcakes and plenty other recipes on my blog. They both cook really well and taste great, and I’d highly recommend checking them out.

All that said, I’m not affiliated with either company and can say, use any protein powder you like. I’ll add that leaner types of protein like whey isolate tends to be a little tough or dry in baked goods, and plant-based powders can be a bit granular in texture. The answer for both is usually either scaling back on the protein powder used a tiny bit or adding a bit of extra fat (like light butter or real butter, coconut oil, or a replacement like apple sauce).

Update 3/2019: I’ve added notes to the recipe card below for Bowmar Nutrition protein powder.

And one last thing on protein powder. If you use a different powder, keep the scoop size in mind. I’ve included the weight of the two scoops of PEScience in this recipe. Your protein powder should have the weight of each scoop on its nutrition label for comparison. 80 grams of protein powder will definitely cook differently than 62 grams of protein powder.

I shared the photo above in my Instagram story with all the failed attempts during recipe development. Small changes can take a cupcake from fluffy to rock hard in the blink of an eye. 

Sugar Free Frosting

This one is easy. I used a straight out of the container sugar free frosting to keep things super simple. While the macros aren’t amazing, the frosting sure is tasty and super creamy.

If you wanted to save some calories by making your own macro friendly frosting, I have a couple recipes you can try:

For comparison, the current recipe’s frosting equates to 400 calories, 0g protein, 68g carbs, and 24g fat. Or 33 calories, 6g carbs, and 2g fat per cupcake. Using another option will take a bit more time in the kitchen but will definitely save some calories.

Okay, I think you’re good to go. If you make these super simple protein cupcakes, I wanna know about it. Snap a pic and tag me on Instagram. I’ll be sure to share it with everyone.

99-calorie simple protein cupcakes

5-Ingredient Simple Protein Cupcakes

Yield: 12 protein cupcakes
Prep Time: 10 minutes
Cook Time: 15 minutes
Total Time: 25 minutes

A quick and easy recipe for 99-calorie protein cupcakes with chocolate frosting. 


  • 1 C (113g) Pillsbury Sugar Free Yellow Cake Mix, measurement is an approximation since it's not calculated on the packaging
  • 2 scoops (62g) PEScience Protein Powder, vanilla
  • 3 large Eggs
  • 1/4 C (60mL) Unsweetened Almond Milk, or your choice of liquid
  • 1/2 C (120g) Pillsbury Sugar Free Chocolate Fudge Frosting


  1. Preheat oven to 325F and spray a 12-muffin tin with nonstick cooking spray or prepare 12 silicone baking cups (my preferred method). 
  2. Mix the dry ingredients in a large bowl before adding the eggs and almond milk. Stir well.
  3. Use a spoon to transfer the cupcake batter to the baking cups or muffin tin, filling each about half way. Start on the lighter side and fill in at the end as needed so you don't run out of batter before you fill all 12.  how to make simple protein cupcakes
  4. Bake for 12-14 minutes or until a toothpick comes out clean. 
  5. After the protein cupcakes have cooled slightly, use a knife or icing spatula to spread the frosting on each cupcake. Top with sprinkles if you'd like (not included in nutrition info). 


*With whey-only protein powder, use 4 scoops (112g) and keep everything else the same. 

Each cupcake has 2 Smart Points.

The current frosting equates to 400 calories, 0g protein, 68g carbs, and 24g fat. Or 33 calories, 6g carbs, and 2g fat per cupcake.

By the way, the silicone baking cups you see in the instructions are too legit to quit. They’re easily one of the best kitchen purchases I’ve made recently.

When I see "5 ingredients" on a recipe I automatically click it. I am so tired from work once I get home yet I want a delicious and easy snack at the same time. Well these are super easy to make when you're tired but have a sweet tooth. I didn't have the yellow cake mix at first but added it to my grocery list that weekend and made these the next day. They taste like a nice moist cake. Super yummy and high protein!! I highly recommend. Mine didn't come out as pretty as Mason's but they were sure tasty!!
