Keto Protein Birthday Cake

Every birthday celebration should end with something sweet – preferably a big, layered cake topped with icing and loaded with carbs.

However, chocolates, shakes, and brownies are also welcomed on this special day. Normally, most people don’t care about carbs in sweets, especially not on birthdays. But when you or your friend is following a keto diet, those unwelcomed carbs will definitely ruin all the fun.

Luckily, it is possible to make beautiful and delicious cakes and other birthday sweets with few carbs. What’s even better is that we’ve created flavorful keto protein cake and sweets recipes that pack a serious protein and MCTs punch. These will make your birthday celebrations even more keto friendly. So, check out our keto protein birthday cake recipes below to celebrate your next birthday the keto way.

What Are Keto Protein Cakes?

Keto protein cakes are keto-friendly birthday cakes that include our Keto Protein Birthday Cake powder. This product contains hydrolyzed collagen peptides and MCT powder – two highly effective keto ingredients. Collagen peptides are easily digestible proteins that support gut, skin, and joint health, while MCT powder is a source of medium-chain triglycerides, fats that the body turns quickly into ketones. The product, of course, is birthday cake flavored, making it ideal for birthday dessert making.

Cake vs. Keto Protein Cake

A slice (77g) of your average birthday cake has around 300 calories, 40g of net carbs, and only 2g of protein. Our keto protein birthday recipes, on the other hand, have varying amounts of calories, less than 5g of net carbs on average, and up to 11g of protein. The macros do vary from one recipe to the next. But one thing is for sure – our keto protein cakes will not kick you out of ketosis and they’re rich in protein.

Are Keto Protein Cakes Low Carb?

Absolutely. All recipes listed below have less than 5g of carbs per serving. Many of these recipes replace wheat flour with coconut and almond flours. Nut flours, in general, tend to be high in fat and fiber while being low in carbs. Most recipes call for both types to help create the same texture and taste you would expect with classic dessert. Our recipe also replace sugar with erythritol and stevia, which are healthy low-carb sweeteners.
