3 Ingredient Low-Carb Vanilla Protein Cake Recipe!

If you’re looking for a super simple, high protein cake that you can enjoy anytime, you’re in the right place!

This recipe comes with a warning: “WARNING: Do not overbake your cake; if you overbake it, it’ll go rubbery, dry, and lose all its deliciousness.” It also comes with a bit of a twist: “TWIST: If you underbake your cake, you’ll end up with a delicious custardy cake; no, you won’t be able to layer it with frosting BUT it’ll be like a smooth little mousse-type-thing, jam-packed with protein!

OK. With that out of the way, allow the recipe to proceed:


Ingredients for the Cake, you get four cakes):

2 cups (pausterized) liquid egg whites
1 cup vanilla whey protein powder
1/2 cup coconut flour 

Ingredients for the Filling (per tower):

1/4 cup chocolate whey protein powder
1/2 cup milk
2 tablespoons coconut flour
1/2 tablespoon cocoa powder


1. To get your cake into that custardy cake as mentioned before , bake it for no more than 10 minutes at 170 C (320 F) or until the centre is slightly wet but the sides have more of less set.

2. Bake the mix inside four small porcelain ramekins. This is pretty vague but you need to play around with it a bit. If you want to get it cakey to layer it up with frosting , take it out after 17-18 minutes, when it will have cooked through. Be careful not to overbake it. Just keep and eye on it and take it out as soon as it cooks.

3. For the frosting, all you need to do is mix all the ingredients together in a bowl and boom – you’re done. Add more liquid if you want it creamier or even some Greek yogurt. You can add more cocoa if you want too or some zero calorie syrups.

Macros per cake (without the frosting out of 4):

244.6 kcals
6.9 g carbs
36.3 g protein
6.7 g fat
6.8 g fibre

The frosting will then add the following macros per four-story tower:

327.1 kcals
18.4 g carbs
34.8 g protein
9g fat
9.8 g fibre

You can make  four little cakes to create four towers by cutting the cakes horizontally (once they’d cooled) and adding the frosting in between. Then roll the whole thing in 100% unsweetened cocoa to create some truly ominous-looking cocoa towers. The cocoa on the outside is optional, It kind of adds a nice bitterness to the whole thing.

Remember you can make shorter towers too or, if you’re feeling lazy, just add the filling on top as a type of frosting!
