This keto German chocolate layer cake is a showstopper with layers of coconut-pecan filling and a rich chocolate ganache.
It’s a naked keto German chocolate layer cake, and it’s incredible! Get ready to fool your tastebuds with a decadent tasting recipe that is low in carbs and keto-friendly.
Of course, I have given instructions for making a two-layer cake if this is what you prefer.
My recipe uses my favorite, moist keto Hershey’s chocolate cake I doubled the recipe, to make it a spectacular four-layer cake but have instructions for making it a two-layer cake too.
Keto German Chocolate Layer Cake
A traditional German chocolate cake gets its name from the man who created the recipe, Samuel German, and not the country.
He created a blend of chocolate that was sweet and it was lighter in color and had a milder chocolate flavor. Since this is a low-carb German chocolate cake, there was no sweet baking chocolate used and I went for a bolder chocolatey flavor by using cocoa powder instead.
Plus in the case of the classic recipe, the cake is usually completely frosted in coconut pecan frosting. But I opted to make this a naked layer cake so that you can enjoy all the flavor without it being cloyingly sweet.
The layers of sugar-free coconut pecan filling peeking out make it a stunner for sure.
I also topped off the cake with a chocolate ganache and more toasted pecans for good measure. It made the perfect keto birthday cake and a fun and delicious way to celebrate my brother Paul’s day.

This recipe has three distinct parts and I’ll walk you through each one so that you feel confident that you can duplicate the recipe.
First, is the keto-friendly chocolate cake. It’s made with a combination of almond flour and coconut flour and has the best texture. It gets its rich flavor from natural cocoa powder. The use of eggs, butter, and heavy cream in the batter not only provides richness but moisture.
The second part of this classic cake is the coconut pecan filling, without a doubt, it’s the star of this cake.
I was able to duplicate the flavor by using unsweetened coconut flakes, sugar-substitute, heavy cream instead of evaporated milk, egg yolks, butter and further enhancing the flavor by toasting the pecans.
The third and final part of the cake is the addition of chocolate ganache which I only added to the top layer. It’s totally an optional step but makes for a lovely presentation and added flavor of course.
What You’ll Need
- Almond flour finely milled measured and sifted
- Coconut flour
- Cocoa powder
- Baking powder
- Granulated sugar-substitute
- Unsweetened coconut flakes
- Eggs, room temperature
- Butter, unsalted
- Heavy Cream
- Sugar-free chocolate chips if making the ganache
- Vanilla extract
- Instant espresso coffee, to intensify the chocolate flavor (optional)
- Sifter, to sift the almond flour
- Electric mixer
- Mixing bowls
- 4-quart saucepan, to make the filling
- 9-inch cake pans
- Nonstick frying pan, to toast the pecans
As far as the best sweeteners for this sugar-free German chocolate cake, I recommend the use of Lakanto’s granulated sugar substitute it’s their erythritol and monk fruit sweetener that is as close to sugar as it gets.
Having said that, you can also use the brand Swerve which is an erythritol blend. Similar to Lakanto it uses sugar alcohols and has a 0 % impact on blood sugar.
You could also use the stevia and erythritol-based brand Pyure if you prefer to use a stevia-based sweetener. I will however add that we are not sure why but chocolate and stevia do not always place nice and can intensify the aftertaste of stevia.
It’s not my preference to ever use stevia in chocolate recipes for this reason. Due note, that if this is your pick make sure you reduce the amount called for in the recipe by half since it’s a much sweeter option.
Lastly, if you can’t easily find a more natural sugar substitute you can also use Splenda with good success. I know not everyone would agree with me here and I respect that but in my book, it’s still better than regular sugar.

Join Our Jesus And Keto Movement
Randy and I came to the keto diet looking at it from a Christian perspective. As believers, we live our lives supported by God’s grace.
So when the Holy Spirit led us to combine our Christian faith and the keto diet, we did so in hopes of finding lasting transformation.
To say we needed God’s intervention is putting it mildly. When we followed the Holy Spirit’s prompting to we got on the path to real transformation.
Knowing firsthand the benefits of this decision we have created a closed Christian group that is using the keto diet to transform their lives. We invite you to join our Private Facebook Group and see if it’s not the key you have been missing.

- While the cake bakes proceed to make the frosting.
- Allow the cake to cool for about 20 minutes on a baking rack. Then using a thin knife run around the edge of each cake before carefully removing the cakes out of the pans. Return back to the cooling rack to cool completely.

- To make the frosting add the granulated sugar substitute, heavy cream, and egg yolks into a large saucepan. Whisk all the ingredients until fully combined.

- Add the second cake layer over the frosting. Add the remaining on top and spread evenly to the edge of the cake.
- Store leftovers in the refrigerator for up to 5 days. I do not recommend you freeze the cake after it's been frosted. If you need to freeze the cake do so before frosting and make the frosting the day it is defrosted.
