CARROT CAKE PROTEIN SLICES
My all-time favorite cake is carrot cake, so I’m constantly perfecting my “healthified” version to taste as close as possible to the real thing. After making these Carrot Cake Protein Slices, I had some store-bought “all-the-oil” “all-the-sugar” carrot cake. The verdict? Well, the store-bought carrot cake had more raisins and coconut (which I loved), but otherwise, this is equally delicious and I actually liked my cream cheese frosting better! It’s a must-try if you love carrot cake as much as I do 😉 This recipe was even named one of the top 50 high protein desserts on FeastGood.com!

Which type of whey is best for baking?
The protein powder I used in this recipe is Quest Protein Powder in Vanilla Milkshake. You can really use any brand of protein powder so long as it’s a whey concentrate or whey blend. I don’t recommend baking with whey isolate because it usually results in baked goods that are dry and crumbly or oddly “spongey.”
Collagen and vegan protein powders behave much differently compared to whey, so they cannot be substituted without multiple modifications (which I have not tested).
For perfect amount of sweetness, I added my favorite organic, calorie-free stevia blend that’s twice as sweet as sugar. If you need to substitute erythritol, monk fruit, baking stevia or another sweetener that measures 1-to-1 like sugar, use twice as much (half a cup).
You can also use a calorie-free brown sugar alternative for an even richer taste! My favorite is this monk fruit brown sugar alternative. Other options include Sukrin Gold, Lakanto Golden, or Swerve Brown Sugar. These all measure 1:1 like sugar so use double the amount (half a cup). You could also substitute one-quarter cup of Truvia or Splenda brown sugar blend, though this will add some calories and sugar (they’re not sugar-free)!
I used coconut flour to keep the carbs low, but feel free to substitute twice as much (one-quarter cup) of gluten-free baking flour, gluten-free oat flour, or cassava flour (Paleo). You could also try a quarter cup of all-purpose flour, brown rice flour, cake flour, sweet white sorghum flour, spelt flour, tiger nut flour or whole wheat pastry flour! If substituting almond flour, you will likely need 3-4 times as much, so start with six tablespoons but you may need up to half a cup.
To add moisture to these protein slices, I combined grated carrot, unsweetened applesauce, and almond butter. There is no real substitution for the first two, but you can totally swap the almond butter for cashew butter, or one-quarter cup of almond flour plus 1-2 tablespoons of melted coconut oil.
This recipe also calls for one egg white which can be swapped for one tablespoon of ground flaxseed plus two tablespoons of water for an egg-free version. The unsweetened almond milk can be substituted for unsweetened coconut milk or any milk you have!
Feel free to add some raisins, unsweetened shredded coconut, and chopped walnuts (or pecans) to these Carrot Cake Protein Slices too 😉
For the frosting I simply combined Greek cream cheese (found this at Walmart), confectioner’s erythritol (a sugar-free alternative to powdered sugar), a little Quest Protein Powder in Vanilla Milkshake, and vanilla extract. The frosting is so good! If you can’t find Greek cream cheese, neufchâtel cheese or reduced fat cream cheese would also work. You can even use dairy-free cream cheese!
