Ingredients Overview
This chocolate keto cake uses simple, easy-to-find ingredients that combine to create a truly exceptional dessert. Here’s what you’ll need:
- Almond Flour – The foundation of our cake, providing structure while keeping carbs low. Make sure to use fine almond flour (not almond meal) for the best texture.
- Cocoa Powder – Regular and Dutch-process cocoa create depth of flavor and that rich chocolate color.
- Baking Powder – Provides the perfect rise for a fluffy texture.
- Salt – Enhances all the flavors, especially chocolate.
- Liquid – Water or any milk of your choice works well.

- Erythritol – A keto-friendly sweetener that tastes like sugar without the carbs. Regular sugar works if you’re not counting carbs.

Tools You’ll Need
Tools You’ll Need:
- • 8-inch round cake pan
- • Parchment paper
- • Mixing bowl
- • Whisk or electric mixer
- • Measuring cups and spoons
- • Cooling rack
Step-by-Step Overview
Making this chocolate keto cake is surprisingly simple! Follow these steps for the perfect low-carb chocolate cake:
- Step 1
Preheat your oven to 350°F (175°C). Prepare your 8-inch cake pan by greasing it thoroughly and lining the bottom with parchment paper. This step is crucial for easy removal after baking.
- Step 2
In a large mixing bowl, combine all ingredients: almond flour, cocoa powders, baking powder, salt, water/milk, eggs, erythritol, and vanilla extract. Mix thoroughly until the batter is smooth and well combined. The batter will be thicker than traditional cake batters – this is normal for almond flour recipes.
- Step 3
Pour the cake batter into your prepared pan. If the surface is uneven, use a second sheet of parchment paper to gently press and smooth it out. This technique prevents your hands from sticking to the batter while ensuring a nice, even top.
- Step 4
Bake on the center rack for 14 minutes. Check for doneness by inserting a toothpick – it should come out clean or with just a few crumbs when the cake is ready. If needed, bake for a few more minutes until the cake is firm to the touch.
- Step 5
Allow the cake to cool completely in the pan before removing. This patience is crucial – the cake structure continues to set as it cools, and removing it too early could cause it to break. Once cooled, it’s ready for frosting!

Making a Double-Layer Cake
If you’d like to create a showstopping double-layer chocolate keto cake:
- Step 1
Double all ingredient quantities in the recipe.
- Step 2
Prepare two 8-inch cake pans instead of one.
- Step 3
Divide the batter equally between the two pans.
- Step 4
Bake as directed, checking for doneness at the 14-minute mark.

Cool both layers completely before frosting between layers and around the outside.
Tips & Tricks
Recipe Notes:
- Room temperature eggs blend more easily with other ingredients for a smoother batter.
- The combination of regular and Dutch cocoa powders creates a deeper, more complex chocolate flavor. If you only have one type, that’s fine too!
- Don’t overbake! Almond flour cakes can dry out quickly. It’s better to slightly underbake than overbake.
- For the vegan version, use a flax egg (1 tablespoon ground flaxseed mixed with 3 tablespoons water) or commercial egg replacer for each egg.
- Store leftovers in an airtight container in the refrigerator for up to 5 days.
Variations
Make this chocolate keto cake your own with these delicious variations:
- Triple Chocolate: Add 1/4 cup sugar-free chocolate chips to the batter for even more chocolate goodness.
- Mocha Cake: Add 1 tablespoon of instant espresso powder to the batter for a coffee-chocolate flavor.
- Orange Chocolate: Add 1 teaspoon of orange extract and 1 tablespoon of orange zest to the batter.
- Spiced Chocolate: Add 1/2 teaspoon of cinnamon and a pinch of cayenne for a Mexican chocolate-inspired kick.
- Mint Chocolate: Add 1/2 teaspoon of mint extract to the batter for a refreshing twist.
Frosting Ideas
Complete your chocolate keto cake with one of these delicious keto-friendly frosting options:
- Chocolate Cream Cheese Frosting: Blend 8oz softened cream cheese, 1/4 cup softened butter, 1/3 cup powdered erythritol, 1/4 cup cocoa powder, and 1 tsp vanilla extract until smooth.
- Whipped Cream Frosting: Whip 1 cup heavy cream with 2 tbsp powdered erythritol and 1 tsp vanilla until stiff peaks form.
- Chocolate Ganache: Heat 1/2 cup heavy cream until almost boiling, pour over 3/4 cup sugar-free chocolate chips, let sit 2 minutes, then stir until smooth.
- Peanut Butter Frosting: Mix 1/2 cup natural peanut butter, 2 tbsp softened butter, 1/4 cup powdered erythritol, and a splash of heavy cream until smooth.
- Coconut Cream Frosting: Whip the solid portion of chilled coconut cream with 2 tbsp powdered erythritol and 1/2 tsp vanilla until light and fluffy.
Storage & Reheating
Your chocolate keto cake will stay fresh and delicious with proper storage:
- Counter: Store unfrosted cake in an airtight container at room temperature for up to 2 days.
- Refrigerator: Store frosted cake in an airtight container for up to 5 days. Unfrosted cake will last up to a week.
- Freezer: Wrap individual slices or the whole unfrosted cake tightly in plastic wrap, then aluminum foil. Freeze for up to 3 months. Thaw in the refrigerator overnight before serving.
- Reheating: Microwave individual slices for 10-15 seconds to restore that fresh-baked texture and enhance the chocolate flavor.
FAQ
Can I use coconut flour instead of almond flour?
Coconut flour absorbs much more liquid than almond flour, so it’s not a direct substitute. If you want to use coconut flour, you would need to completely reformulate the recipe with more eggs and liquid.
Is this cake suitable for diabetics?
While this cake is low in carbohydrates and uses a sugar substitute, individual responses to ingredients vary. People with diabetes should consult their healthcare provider about incorporating this recipe into their meal plan.
How many net carbs are in this chocolate keto cake?
Each serving contains approximately 4g net carbs, making it suitable for most keto diets. The exact count will vary slightly depending on your specific ingredients and serving size.
Can I use a different sized pan?
Yes, but you’ll need to adjust baking times. A larger pan will require less baking time as the cake will be thinner, while a smaller pan will need more time as the cake will be thicker.
Why did my cake turn out dry?
The most common reason for a dry keto cake is overbaking. Almond flour doesn’t behave exactly like wheat flour and can dry out quickly. Check the cake early and remove it when a toothpick inserted comes out with a few moist crumbs.
