If you are wondering if Hershey’s cocoa powder is keto-friendly, rest assured it is.

The good news is that cocoa powder has zero sweeteners and can, therefore, be used in keto baking.

This means you have the green light to use Hershey’s cocoa powder while doing keto.

Let me start off by saying that my love for Hershey’s Chocolate cake is two-fold.

One is the fact that it’s a super easy recipe to execute, and two is that it boasts a rich chocolate flavor. It’s a winner, for sure!

I can’t tell you with certainty, but I’m pretty sure that the recipe on the back of the cocoa box was probably the first chocolate cake I made from scratch a kazillion moons ago. 

Don’t get me wrong, I know there are some fancier brands of chocolate out there, but here’s the thing: Hershey’s brand of chocolate has never disappointed me. Not even once.

Keto Chocolate Butter Cream Frosting

I have also included a low-carb chocolate buttercream frosting as an option that only slightly increases the net carbs from 3.4 to 4.2 net carbs. 

It’s a great chocolate frosting to include for special occasions, even as a chocolate keto birthday cake. 

I’ve also shared in the recipe card how to make this a layer cake or cupcakes, depending on your choice of pans. 

  • Unsalted butter, room temperature​ softened
  • Cream cheese softened at room temperature
  • Sugar substitute confectioner’s sugar
  • Hershey’s unsweetened natural cocoa powder
  • Sea salt
  • Heavy cream
  • Vanilla extract

How To Make A Keto Hershey’s “Perfectly Chocolate” Cake

I’ll admit that at first, I thought that my attempt to convert this classic recipe into a keto-friendly option was going to be impossible.

Thankfully, that was not the case. A little prayer before attempting to convert a recipe is the secret to my success.

Thankfully, the keto-friendly version of the classic Hershey’s cake produced a moist cake that is also flat-out delicious. 

It’s now one of our family’s favorite cake recipes!

Just like the original recipe, you will start by mixing the dry and wet ingredients in two separate bowls. 

I did, however, replace the vegetable oil that’s called for in the original with melted, cooled butter. Because butter is always a good idea. Don’t you agree?

You can also use melted refined coconut oil or ghee in place of the butter. If you opt to use coconut oil, I suggest you use refined coconut oil so that the coconut flavor doesn’t overpower the recipe.

Instead of the 1 cup of milk, I used 1/2 cup of heavy whipping cream and 1/2 cup of water. The milk is way too high in carbs.

This cream and water combo works as a great substitute. 

I also used three large eggs instead of the two that the original recipe called for to ensure the cake would be moist and have the perfect crumb.

Of course, in order to make this a true Keto Hershey’s Chocolate Cake, I also swapped out the sugar for a sugar substitute and the all-purpose flour for a finely milled almond and coconut flour combination.

Then, it was just a matter of combining the wet ingredients with the dry and then stirring in the cup of boiling water at the end.

Don’t be surprised by the fact that this recipe has a thin batter; this is exactly the consistency you want and mimics the traditional Hershey’s cake. 

A Keto Chocolate Cake For A Magnesium Boost

Usually, when I find myself craving chocolate, it’s an indicator that my magnesium levels may be a little low.

At that point, I make sure I take some magnesium and then proceed to the kitchen to find some chocolate, and that usually translates into a low-carb chocolate cake.

It’s pretty incredible how our bodies can tell us what we need if we learn to tune in.

My keto cake recipe is a great alternative to the original recipe. It is just as rich-tasting and easy to make.

Having the ability to enjoy a classic chocolate cake without the worry of it causing you to slip is why I am so passionate about creating keto recipes.

Sugar-Substitutes That Work With This Keto Chocolate Cake

When it comes to choosing which sugar substitute to use for what our family considers the best keto chocolate cake, I have several for you to choose from. 

My first choice is Lakanto Monk FruitThis is because it really behaves the most like regular sugar, as far as I am concerned. It is a monk fruit and erythritol blend.

Lakanto Monk Fruit gets its sweetness from antioxidants called mogrosides, instead of fructose or sucrose. That’s why it’s a great all-natural sugar substitute and has zero calories and zero glycemic index.

I’m, however, also partial to Swerve, which is an erythritol blend. Swerve is made from ingredients found in select fruits and starchy root vegetables and contains no artificial ingredients, preservatives, or flavors.

Swerve is the name brand of Erythritol. It’s unlike other sugar alcohols that have a 0 % impact on blood sugar.

You could also use the stevia and erythritol-based brand Pyure for most of my baked goods.

But I personally am not a fan of stevia-based sweeteners because I find that I am quite sensitive to bitter aftertastes. And in chocolate recipes, this seems to be magnified. 

Having said this if you are accustomed to using it and don’t have an issue, then I recommend using the Pyure brand. However, you will want to use half the amount called for in this recipe since it’s much sweeter.

Lastly, if you can easily find a more natural sugar substitute, you can also use Splenda with great success. 

You will want to use Splenda, which has a bulking agent. It’s the one that comes in larger bags. I don’t recommend Splenda Bake because it’s actually a half-sugar, half-sucralose product and will be too high in carbs to be considered keto-friendly.
