🍫 Ultra-Moist Steamed Chocolate Cake
Incredibly moist, deeply chocolatey, and made without an oven, this steamed chocolate cake is the perfect dessert when you want a rich homemade cake with a wonderfully soft texture.
Steaming keeps the cake exceptionally tender and moist, while hot coffee or water intensifies the chocolate flavor. A glossy chocolate coating poured over the top finishes it with a smooth, fudgy layer.
It’s simple enough for an everyday treat but impressive enough for birthdays, celebrations, and afternoon coffee.

🛒 Ingredients
For the Cake
- 1½ cups (190 g) all-purpose flour
- ½ cup (45–50 g) unsweetened cocoa powder
- 1 cup (200 g) granulated sugar
- 1 teaspoon baking powder
- ½ teaspoon baking soda
- ¼ teaspoon salt
- 2 large eggs, room temperature
- ½ cup (113 g) unsalted butter, melted and slightly cooled
- ¾ cup (180 ml) milk
- 1 teaspoon vanilla extract
- ½ cup (120 ml) hot water or hot coffee
🍫 For the Chocolate Coating
- ½ cup (120 ml) heavy cream
- 1 cup (170 g) semi-sweet or dark chocolate chips, or finely chopped chocolate

👩🍳 Instructions
1. Prepare the Steaming Setup
Fill a large pot with approximately 2–3 inches (5–7 cm) of water.
Place a steaming rack inside.
Bring the water to a gentle simmer while preparing the cake batter.
The water should be steaming steadily but not violently boiling.
2. Prepare the Cake Pan
Grease an 8-inch (20 cm) round cake pan with butter or nonstick spray.
Line the bottom with parchment paper.
For easier removal, lightly grease the parchment as well.
Set aside.
3. Combine the Dry Ingredients
In a large bowl, whisk together:
- Flour
- Cocoa powder
- Sugar
- Baking powder
- Baking soda
- Salt
Whisk thoroughly to break up any cocoa lumps.
4. Combine the Wet Ingredients
In a separate bowl, whisk together the eggs, melted butter, milk, and vanilla extract.
Make sure the melted butter has cooled slightly so it doesn’t cook the eggs.
5. Make the Batter
Pour the wet ingredients into the dry ingredients.
Whisk gently until just combined.
Don’t overmix—the batter should be smooth but not beaten excessively.
6. Add the Hot Liquid
Slowly pour in the hot water or hot coffee, whisking gently as you add it.
The batter will become noticeably thinner.
Don’t worry—this is intentional.
The thin batter helps create an exceptionally moist and tender steamed cake.
If using coffee, choose plain brewed coffee rather than strongly flavored coffee. It enhances the chocolate flavor without making the cake taste like coffee.
7. Fill the Cake Pan
Pour the batter into the prepared cake pan.
Gently tap the pan once or twice on the counter to release large air bubbles.
Cover the top of the pan tightly with aluminum foil.
This is important because it prevents condensation from dripping onto the cake.
8. Steam the Cake
Place the covered cake pan on the steaming rack.
Cover the pot with a tight-fitting lid.
Steam over medium heat for 45–55 minutes.
Try not to lift the lid during the first 40 minutes, as releasing the steam can affect the cake’s rise.
The cake is done when a toothpick inserted into the center comes out with a few moist crumbs but no wet batter.
9. Cool the Cake
Carefully remove the cake pan from the steamer.
Remove the foil and allow the cake to cool in the pan for about 10–15 minutes.
Run a thin knife around the edges, then carefully invert the cake onto a cooling rack or serving plate.
Allow it to cool further before adding the chocolate coating.

10. Heat the Cream
Place the heavy cream in a small saucepan.
Heat over medium-low heat until it is hot and steaming, but do not bring it to a full boil.
Remove from the heat.
11. Add the Chocolate
Place the chocolate in a heatproof bowl.
Pour the hot cream over the chocolate.
Let it sit undisturbed for 2 minutes.
Add the butter and optional corn syrup or honey.
12. Stir Until Smooth
Slowly stir from the center outward until the chocolate melts completely and the mixture becomes smooth, glossy, and silky.
If a few chocolate pieces remain unmelted, place the bowl over a saucepan of barely simmering water for a few seconds and stir until completely smooth.
13. Coat the Cake
Place the cooled cake on a serving plate.
Pour the chocolate coating over the center of the cake.
Use an offset spatula or the back of a spoon to gently spread it toward the edges, allowing some chocolate to naturally drip down the sides.
Let the coating sit for 15–20 minutes before slicing.
For a firmer chocolate topping, refrigerate the cake for about 30 minutes.
⭐ Chef’s Tips
Don’t skip covering the pan: Steam condensation can make the surface of the cake wet and uneven.
Keep the steam steady: Too little steam can leave the cake undercooked, while extremely vigorous boiling can create an uneven texture.
Use hot coffee for deeper chocolate flavor: Coffee intensifies cocoa without making the finished cake taste strongly of coffee.
Don’t overmix: Once the flour is incorporated, stop mixing.
Check the water level: If your steaming time is long, make sure the pot doesn’t run dry. Add more hot water if necessary.
Cool before coating: A very hot cake can cause the chocolate coating to become excessively thin and run off.
For the moistest texture: Don’t over-steam the cake. Remove it as soon as a toothpick comes out with a few moist crumbs.

Sprinkle chopped toasted walnuts, pecans, or hazelnuts over the chocolate coating.

- Fresh strawberries
- Raspberries

🧊 Storage
Store the cake in an airtight container.
Keep at room temperature for up to 2 days if your kitchen is cool, or refrigerate for up to 4–5 days.
If refrigerated, allow slices to sit at room temperature for about 15–20 minutes before serving for the softest texture.
❄️ Freezing
The steamed chocolate cake can be frozen for up to 2 months.
For best results, freeze the cake without the chocolate coating.
Wrap it tightly in plastic wrap, followed by aluminum foil.
Thaw overnight in the refrigerator, then bring to room temperature before adding the chocolate coating.
