I’ve been meaning to make a flourless chocolate cake keto, after making a vegan flourless chocolate cake and a zucchini chocolate cake. 

Flourless keto chocolate cakes have a different texture. As it is made with no flour and no grains, it can be a little heavier and less fluffy. However, it is just as delicious.

Also known as a low carb torte, this keto flourless cake is a game changer!

How to make a keto flourless chocolate cake

I tested this recipe out two ways, as I’d always like to offer an eggless vegan version. See further down the post for that particular option.

The Ingredients

• Keto Chocolate– I don’t recommend using sugar free keto chocolate chips, as they don’t have the best melted texture. For this keto flourless chocolate cake, use a chopped up unsweetened chocolate bar. Although bitter on its own, you won’t taste the bitterness once baked. 
• Butter– Unsalted butter or grass fed butter. Try to use a good quality butter, preferably from sticks. Cheaper brands and butter from a block can often contain added water. 
• Granulated sweetener– Erythritol or monk fruit sweeter (granulated) can be used. I haven’t tried other keto sugar substitutes.
• Salt– A must for this keto flourless cake- It brings out the sweetness! 
• Espresso powder– Optional, but intensifies the chocolate flavor!
• Vanilla extract- Gives a light vanilla note that enhances the chocolate. 
• Eggs– Keep the eggs at room temperature. 
• Cocoa Powder– Use a good quality cocoa powder, as some of the cheaper ones are clumpy and don’t have a rich chocolate flavor. 

The instructions 

Please note, I doubled the recipe to make a flourless layer chocolate cake. If you also choose to do that, double the amounts for all the ingredients. 

You can use either a microwave or stovetop to melt the butter with chocolate. I didn’t notice much of a difference between them. 

When the cake is mostly baked, you’ll notice the tops having a thin crust. This is completely normal and is supposed to happen.

Let the cake cool in the pan completely. Once cool, you can gently remove it (it will have sunk slightly in the middle) or flip it upside down onto a plate. 

Vegan Gluten Free Flourless Chocolate Cake Option

For a vegan gluten free flourless chocolate cake, I used the following recipe:

2 ½ cups rolled oats, 1 tbsp baking powder, 2 tbsp cocoa powder, ¾ cup sugar of choice, 1 cup mashed sweet potato (or pumpkin), 1 flax egg (1 tbsp ground flaxseed with 3 tbsp water, sitting for 10 minutes to form a gel), 1 cup dairy free milk,¼ cup coconut oil.

Add all the ingredients into a high-speed blender or food processor and blend until smooth. Transfer to an 8-inch cake pan and bake for 25-30 minutes, until a skewer comes out clean. 

Low Carb Flourless Chocolate Cake Tips

• For ease of removal, don’t simply grease the cake pan. Instead, cut a piece of parchment paper to fit the base. 
• If you don’t use the microwave, heat the butter and chocolate over extremely low heat. 
• Do not overmix the cake batter after adding in the cocoa powder- carefully fold it through until it is just combined. 
• Any chocolate frosting works. You can keep it unfrosted, and it will still be delicious!
• The low carb flourless chocolate cake must be cooled completely, before frosting. 
• Be careful when transferring the cake from the pan, as it will be fragile. 

Storing and Freezing Tips

• To store: Leftover flourless chocolate cake must be stored in the refrigerator, especially if it has frosting on it. Keep it covered or in a sealable container, and it will remain fresh for up to 2 weeks.
• Can you freeze a flourless chocolate cake? You can freeze this flourless chocolate cake. Keep leftover cake in a freezer friendly container, and it can be stored in the freezer for up to 6 months. 

To enjoy this flourless chocolate cake from a frozen state, thaw overnight in the fridge, before allowing to thaw at room temperature the day of consumption. 

DO NOT reheat using an oven or microwave, as this will thaw and cook it at the same time.
