Keto Protein Cake | Less Than 1 Net Carb Per Cake!

One of the most popular food trends in recent years is keto, an eating style that eliminates carbohydrates to help you reach your weight loss goals. This low carb cake recipe is made using protein powder and unsweetened cocoa powder for a chocolatey keto treat!

This keto protein cake is so easy to make and only has 1 net carb per cake! It’s perfect for breakfast, an afternoon snack, or dessert.

This recipe came to mind as I was driving home from work one day. I’ve been wanting to make some kind of cake for a long time, but I didn’t know how to go about it. I didn’t find it by searching recipes or testing. As I scrolled through my Instagram, I saw a few cakes that made me think I was destined to make the perfect keto cake. And we did. Our protein muffins contain less than one net carbohydrate and taste like a real meal, damn good. See below how I prepare them!

Protein desserts

The secret to this very low carb cake is the protein powder used. We use Isopure protein powder (Cookies and Cream are our favorites). Not only does it contain no carbs, but it has a lot of flavor and is really high quality (in our opinion!). The downside is that it’s a bit expensive, but considering all the benefits, we think it’s worth it! It should be noted that the nutritional value of the brownies will change if you use a different protein powder. When you focus on fat, as keto fanatics do, it’s easy to overlook protein intake. We even make fat bombs! Well, it’s time for protein desserts to take center stage for a change, so we created these bites of protein heaven!

We have a chocolate protein cake for chocolate lovers and a vanilla protein cake for vanilla lovers! Although Matt prefers chocolate – the chocolate icing was his idea – I prefer vanilla. But it’s better to have one of each! One trick to making the frosting creamy and smooth is to make sure the butter is at room temperature when you mix it. Cold butter is not only harder to mix, but it takes longer and has a slightly different texture. However, if you want to avoid the frosting, I suggest adding a few extra drops of stevia to the cake batter for a sweeter cake that looks more like a party cake!
