Ingredients for Keto Chocolate Cake
Below is the base recipe. Measurements are provided in grams for accuracy, with cup equivalents for convenience.
For the Cake
- 4 large eggs, separated
- 15 g (1 tbsp) coconut oil or unsalted butter, melted
- 1 tsp pure vanilla extract
- 150 g (1½ cups) fine almond flour
- 100 g (½ cup) keto-friendly sweetener (erythritol, monk fruit, or allulose)
- 30 g (¼ cup) unsweetened cacao powder, sifted
- ¼ tsp bicarbonate of soda (baking soda)
- 120 ml (½ cup) unsweetened almond milk or coconut milk
- 1 tsp apple cider vinegar
- ½ tsp baking powder
For the Frosting
- 250 g (1 cup) Greek-style yogurt (full-fat)
- 1 tsp cacao powder, sifted
- 1–2 tsp keto sweetener (powdered form)
Ingredient Substitutions and Variations
One of the best things about keto baking is how adaptable it can be. Here’s how you can make changes without compromising the texture or flavor:
- Almond Flour: Can be replaced with ¼ the amount of coconut flour (adjust liquids accordingly).
- Sweetener: Monk fruit or allulose can give a softer texture compared to erythritol.
- Dairy-Free Option: Replace Greek yogurt with coconut yogurt or whipped coconut cream.
- Extra Chocolate Kick: Add sugar-free chocolate chips into the batter.
- Nut-Free Version: Use sunflower seed flour (note: may affect color slightly).
Step-by-Step Instructions
1. Prepare the Pan and Oven
Preheat your oven to 175°C (350°F). Grease and line an 8-inch round cake pan with parchment paper for easy release.
2. Separate the Eggs
Place the whites in a clean, dry bowl and the yolks in another mixing bowl. This step will help create a lighter, airier cake.
3. Mix the Wet Ingredients
Whisk the egg yolks with melted coconut oil and vanilla until smooth and slightly creamy.
4. Combine the Dry Ingredients
In a separate bowl, whisk together almond flour, sweetener, cacao powder, baking soda, and baking powder. Ensure there are no lumps.
5. Make Keto “Buttermilk”
Stir the apple cider vinegar into almond milk and let it sit for 1–2 minutes. This helps activate the baking soda for a better rise.
6. Blend the Batter
Alternate adding the dry mixture and almond milk into the yolk mixture, stirring gently until combined.
7. Whip the Egg Whites
Beat egg whites until stiff peaks form. This adds volume without gluten.
8. Fold Gently
Fold the egg whites into the batter in three parts, being careful not to deflate the mixture.
9. Bake
Pour batter into the pan and bake for 25–30 minutes. Check doneness with a toothpick — it should come out clean or with a few moist crumbs.
10. Cool and Frost
Let the cake cool completely before frosting. Mix Greek yogurt, cacao powder, and sweetener, then spread evenly over the cake.
Pro Baking Tips
- Room Temperature Ingredients: Helps with even mixing and better rise.
- Don’t Overmix: Overmixing deflates the air from the whipped egg whites.
- Check Early: Keto cakes can overbake quickly; start checking at 20 minutes.
- Enhance Flavor: A teaspoon of instant coffee powder deepens chocolate flavor.
- Extra Moisture: A spoon of sour cream in the batter keeps it tender.
Serving Ideas
- With Fresh Berries: Strawberries or raspberries add freshness.
- With Whipped Cream: Use unsweetened cream for a rich contrast.
- As a Layer Cake: Double the recipe and add sugar-free ganache between layers.
- Chilled: Refrigerating for a few hours gives it a fudgier bite.
