Apple Cocoa Cake with No Added Sugar
This apple cocoa cake combines sweet apples, eggs, cocoa powder, and baking powder to make a simple flourless dessert. The apples provide natural sweetness and moisture, while the cocoa adds a rich chocolate flavour.
Expect a soft, dense cake with a texture closer to a baked chocolate pudding than a traditional sponge cake. It tastes delicious chilled and makes a lovely dessert served with plain yogurt or fresh fruit.

How to Make Apple Cocoa Cake
1. Prepare the Oven and Cake Pan
Preheat your oven to 350°F (175°C).
Lightly grease an 8-inch round cake pan with olive oil. Line the bottom with baking paper to help the cake release cleanly.
2. Prepare the Apples
Wash, peel, and core the apples. Cut them into small pieces and place them in a blender or food processor.
Blend until you have a smooth purée. Stop and scrape down the sides as needed. Avoid adding water because the apples already contain plenty of moisture.
3. Add the Eggs
Add the eggs to the apple purée. Blend until the mixture is smooth and evenly combined.
If your blender struggles with the apples alone, add the eggs with the chopped apples and blend them together.
4. Add the Cocoa and Baking Powder
Add the unsweetened cocoa powder and baking powder. If using vanilla, cinnamon, or salt, add them now.
Blend briefly until no dry cocoa remains. Scrape the sides and bottom of the blender to make sure everything is incorporated.
5. Fill the Cake Pan
Pour the batter into your prepared cake pan. Gently smooth the surface with a spatula.
The batter will be wetter than a typical flour-based cake batter.
6. Bake Until Set
Bake on the middle rack for 40–55 minutes, checking from about 35 minutes.
The cake is ready when:
- The edges look set.
- The centre no longer looks liquid or wobbles loosely.
- A toothpick inserted into the centre comes out with moist crumbs but no wet batter.
Baking time can vary depending on the size and juiciness of the apples, the cake pan, and your oven. If the top starts getting too dark before the centre sets, loosely cover it with foil.
7. Cool Before Slicing
Let the cake cool in the pan for 20–30 minutes. Carefully remove it and allow it to cool completely.
For firmer slices, refrigerate the cooled cake for 1–2 hours before serving. The cake is delicate while warm, so avoid cutting it straight from the oven.
Optional Cocoa Yogurt Topping
The basic cake does not produce the glossy chocolate coating shown in some recipe photos. For a simple topping with no added sugar, mix:
- ½ cup thick plain Greek yogurt
- 1 tablespoon unsweetened cocoa powder
- ¼ teaspoon vanilla extract, optional
Stir until smooth, then spread over the completely cooled cake. This topping has a tangy, dark chocolate flavour and will look creamy rather than glossy.
Tips for the Best Results
- Choose sweet apples. Tart apples will make the cake taste less sweet because there is no added sweetener.
- Blend thoroughly. Smooth apple purée gives the cake a more even texture.
- Do not add extra liquid. Water or milk can make it harder for the cake to set.
- Use the correct pan size. A smaller, deeper pan may need a longer baking time.
- Allow plenty of cooling time. Cooling helps the cake firm up and makes slicing easier.
- Expect a dense texture. Without flour or another dry structural ingredient, this cake will not rise like a traditional chocolate sponge.
Serving Suggestions
Serve a slice chilled or at room temperature with:
- Plain Greek yogurt
- Fresh strawberries or raspberries
- A light dusting of unsweetened cocoa powder
- A sprinkle of cinnamon
- A few chopped walnuts or almonds
Toppings are optional and change the nutritional content of the finished dessert.
Storage Instructions
Refrigerator: Store the cooled cake in an airtight container in the refrigerator for 3–4 days. Refrigerate within two hours of baking.
Freezer: Wrap individual cooled slices, place them in a freezer-safe container, and freeze for up to 2 months for best quality. Thaw overnight in the refrigerator. The texture may become slightly softer after thawing.
If using the yogurt topping, add it after thawing for the best texture.
Frequently Asked Questions
Is this cake sugar-free?
It has no added sugar, but apples contain naturally occurring sugars. “No added sugar” is the more accurate description.
Can I leave the apple skins on?
Yes, if your blender can process them very finely. However, peeling the apples produces a smoother texture.
Can I use a loaf pan?
Yes. Line and grease a standard 9 × 5-inch loaf pan. Start checking at 40 minutes and continue baking until the centre is set. The baking time will depend on the batter depth and the pan material.
Why is my cake too wet?
Very large or juicy apples, an underheated oven, or insufficient baking time can leave the centre wet. Measure the ingredients carefully, avoid adding liquid, and check the centre before removing the cake from the oven.
The cake will also feel softer while warm and firm up as it cools.
Will it look exactly like the cake in the photo?
These ingredients produce a moist, dense cake. The tall, airy crumb and thick, glossy chocolate coating in the reference photo are unlikely to come from this ingredient list alone.
Can I call this a weight-loss cake?
Avoid promising weight loss from an individual recipe. Describe it as a flourless apple cocoa cake with no added sugar, which accurately reflects its ingredients.
