When the world gets you down… make cupcakes! Light, fluffy vanilla collagen protein cupcakes to be exact, topped with sweet dairy-free buttercream frosting. Oh, and sprinkles, because sprinkles make everything more fun! One bite and you won’t believe these are high in protein, gluten-free, dairy-free, and virtually sugar-free! Yes, the world just got 10x better 😉 You might also like my Chocolate Collagen Protein Cupcakes.

Did you know? Compared to bovine collagen, marine collagen has a lower risk of transmitting diseases, fewer inflammatory effects, and an up to 1.5 times higher absorption rate! (source)


Collagen recommendations

This is one of the reasons I chose LIV Body’s Marine Collagen for this recipe. It’s flavorless, odorless, with a high bioavailability and tons of health benefits, including improved skin and joint health. Best of all, you can use my code NOEXCUSES for 20% off all LIV Body products.

Feel free to substitute the collagen peptides for an additional quarter cup of flour (30 grams). You can *try* substituting the collagen protein for 30 grams of another protein powder (whey concentrate, whey blend, or vegan protein), but doing so will alter the taste and texture. Too much of these other protein powders (without other modifications), will result in cupcakes that are super dense and dry! YUCK.


Flour substitutions

In this recipe, I went with gluten-free baking flour for light, fluffy, gluten-free cupcakes. Feel free to substitute three-quarters of a cup (90 grams) of any fine flour like brown rice flour, cake flour, cassava flour, sweet white sorghum flour, or whole wheat pastry flour plus one-quarter cup (30 grams) of tapioca flour (starch). Though I haven’t tried it in this specific recipe, you can try half as much coconut flour (six tablespoons) in place of the aforementioned flours for a lower carb version. Please note, the texture will probably be a bit more crumbly.

Sweetener substitutions

To sweeten these cupcakes, I used an organic stevia erythritol blend that’s twice as sweet as sugar. The brand I use has no bitter aftertaste! Feel free to sub double the amount (one half cup) granulated monk fruit, granulated erythritol, or baking stevia. You use also use coconut sugar or granulated sugar, but this will significantly increase the calories, carbs, and sugar per cupcake.


Other substitutions

I also used egg whites, unsweetened dairy-free yogurt, vegan buttery spread, vinegar, and pure vanilla extract in these cupcakes. You should be able to substitute one-quarter cup of water for the egg whites in a pinch. You can also use unsweetened applesauce in place of the dairy-free yogurt, or coconut oil or another neutral-flavored oil in place of the buttery spread. The vinegar helps “tenderize” the cupcakes, but it’s optional (apple cider or white vinegar works)

To make sugar-free buttercream frosting, I use this powdered monk fruit and erythritol blend, which an all-natural, sugar-free, and calorie-free alternative to powdered sugar. You can substitute regular powdered sugar, or simply blend granulated erythritol into a powder. DO NOT sub baking stevia or any type of granulated stevia here or your frosting will be bitter and disgusting!.


I beat the powdered monk fruit and erythritol with tapioca starch (or corn starch), LIV Body’s Marine Collagen (optional), vegan buttery spread, unsweetened almond milk (any milk will do), and pure vanilla extract. The result? The most incredibly rich, smooth, buttery, sugar-free frosting!

And of course, I added some natural sprinkles just for fun 😉
