These Funfetti Protein Cupcakes taste just like cake batter! They’re ridiculously moist, smothered in creamy frosting, and topped with sweet sprinkles. It’s hard to believe there’s only 4g sugar and 13g protein in each 160-calorie cupcake! These cupcakes are also gluten-free (yay).


Protein recommendations

For this recipe, I recommend a whey blend protein combining whey isolate, casein, and milk protein isolate or whey concentrate. I used Quest Protein in Vanilla Milkshake here, but any whey blend should work just fine! You should also be able to use whey concentrate like Garden of Life Organic Whey. I do not recommend whey isolate as it tends to dry out baked goods. Other proteins like plant-based blends and collagen will not work here as they behave much differently than whey.


Flour recommendations

To keep the carbs low without losing that fluffy texture, I combined gluten-free baking flour and coconut flour together. You can swap the gluten-free baking flour for all-purpose flour, brown rice flour, cake flour, cassava flour (Paleo), fine oat flour, sweet white sorghum flour, or whole wheat pastry flour.

The coconut flour can also be swapped out for twice as much of any of the previously mentioned flours (half a cup or 60 grams to be exact).


Sweetener recommendations

I used my favorite organic stevia-erythritol blend to sweeten these cupcakes. It’s calorie-free and twice as sweet as sugar with no bitter aftertaste. If using baking stevia, granulated erythritol or regular sugar, you will need to use twice as much to get the same amount of sweetness.

For the frosting, I used powdered monk fruit sweetener. Confectioner’s erythritol or powdered sugar will also work).


Other ingredients

To keep these cupcakes moist without a ton of fat, I used a combo of nonfat plain Greek yogurt, unsweetened applesauce, and avocado oil (you can also use melted coconut oil!). You can use all yogurt, all applesauce, or more oil in place of either one, but doing so will change the end product’s texture and flavor as well as the macros.

This recipe only calls for one egg white – I’ve found many protein recipes call for a lot of egg to increase the protein content, but unfortunately, that can make for some pretty dense cupcakes! If you can’t have eggs, you can substitute vegan egg replacer or two tablespoons of aquafaba (liquid from a can of chickpeas).

Frosting ingredients

The frosting is just a blend of fat free cream cheese and nonfat plain Greek yogurt with powdered sweetener, more vanilla whey protein, and pure vanilla extract. For the powdered sweetener, you could use powdered erythritol like Swerve, powdered monk fruit, or powdered sugar if you don’t care about the added sugar. If you’d rather not use fat free cream cheese, you can use reduced fat cream cheese, Neufchatel cheese, or even dairy-free cream cheese. Add a little vanilla extract and it’s simply dreamy!

So dang good! Here’s the recipe for these Funfetti Protein Cupcakes… I’d love your comment below if you try it 🙂

    These Mediterranean Turkey Stuffed Peppers are high on the flavor charts and very filling for the calories. These peppers will not only satisfy your tastebuds, but your hunger, too!
