There is no shortage of decadent chocolate recipes on my blog because I LOVE chocolate. It’s a lovely way to add flavor and enjoy a treat that is out of this world. This low carb cake has quickly moved up on my list of favorites. Every moist bite leaves me wanting the next even more. Take it to a potluck, and there won’t even be a crumb leftover. That’s how incredible it is.
I have one little secret for you. Now, I will tell you, but don’t tell your kids! It can be our little secret. 🙂 This low carb chocolate cake has two full cups of shredded zucchini in this cake. Can you believe it? Zucchini is a beautiful ingredient to add in some nutrients, but it also helps keep the cake moist. You can set this cake in front of someone who doesn’t eat low carb, and odds are they won’t even be able to tell the difference in this keto chocolate cake recipe either.
How To Make Keto Chocolate Cake
This cake is very easy to make. The hardest part is smelling the aroma of the fresh baking cake and not being able to eat it yet. Take a look at these simple directions.
First Step: Warm up your oven to 350 degrees F. Then line three 9-inch cake pans with parchment paper. Give them a spray with non-stick cooking spray and set aside.
Second Step: Combine the sweetener, blanched almond flour, unsweetened cocoa powder, baking powder, baking soda, salt, eggs, coconut oil, vanilla extract, unsweetened macadamia milk (or unsweetened almond milk), and zucchini in a bowl. Mix on low until the ingredients are combined, then turn up the speed to medium and continue mixing for 2 minutes. Pour the keto chocolate cake batter into the three pans.
Third Step: Bake the cake layers for 30-35 minutes or until the centers are firm when you touch them. Allow the cake layers to cool for 10 minutes before removing from the pans and letting cool on a wire rack the rest of the way.
Fourth Step: While the cake is cooling, begin preparing the frosting. Warm up the butter, cocoa, sweetener, and half and half in a saucepan. Whisk continuously until smooth, then remove from the heat and pour in the vanilla.
Assembly: Pour ¼ of the frosting over the bottom cake layer. Then add a layer of cake and ¼ more frosting. Add the top layer of the cake and add the rest of the frosting. Allow some of the icing to drip down the edges, top the keto chocolate cake with some chocolate shavings, and enjoy!
Other Types of Keto Frosting
I really do love the chocolate pan frosting on this cake. If you've never made one before it's like an inexpensive version of a ganache. You use cocoa powder and half and half (half milk and half cream) instead of melting chocolate with heavy cream. It is still smooth, rich, and delicious. I could eat it with just a spoon.
I also really want to try this Coffee Frosting! Just sub in swerve for the powdered sugar.
Can you taste the zucchini?
Absolutely not! My kids had no idea there was zucchini. Since the cake it such a dark color you can't see it or taste it. The zucchini is what makes this cake so moist so trust me and don't leave it out. You can use yellow squash in place of the zucchini if you prefer.
More Ideas and Substitutions
- Dairy-Free - the cake itself if dairy-free already. To make a dairy-free ganache heat sugar-free chocolate chips and a little coconut cream until they are melted.
- Nut-Free - a great replacement for almond flour in this keto chocolate cake recipe is sunflower seed flour. It can be subbed 1:1 for almond. You can use carton coconut milk in place of the nut milk. It is not as easy to sub in coconut flour so I don't recommend that.
- Toppings - raspberries look great on this cake! Some other ideas are sugar-free white chocolate chips, drizzled on white chocolate, or piping on peanut butter frosting on top of the chocolate ganache around the edges. You could also stick chopped nuts to the side or sprinkle some on top.
How do you store Chocolate Cake?
You can store the low carb keto chocolate cake in the fridge or on the counter. As long as it’s kept airtight, it will last for several days. I find that it tastes so much better when it’s cool, but try it both ways and see which way you prefer. Making the layer cake in advance, and having it saved for special occasions is easy. This will save you time if you are hosting a party or get-together because you can make it a day or two in advance.
