Ingredients
Dry Ingredients
| Ingredient | Amount |
| All-purpose flour | 2 cups (250g) |
| Unsweetened cocoa powder | ½ cup (50g) |
| Baking powder | 2 teaspoons |
| Baking soda | ½ teaspoon |
| Salt | ¼ teaspoon |
Wet Ingredients
| Ingredient | Amount |
| Large eggs | 4 |
| Granulated sugar | 1 cup (200g) |
| Vegetable oil | ½ cup (120ml) |
| Milk | ¾ cup (180ml) |
| Vanilla extract | 1 teaspoon |
Step-by-Step Instructions
Step 1: Prepare the Pan
Grease an 8-inch (20 cm) tube pan or round cake pan and lightly dust it with cocoa powder or flour.
Step 2: Prepare the Steamer
Fill a large steamer or pot with about 2 inches (5 cm) of water. Bring the water to a gentle simmer before adding the cake.
Step 3: Mix the Dry Ingredients
In a medium bowl, whisk together the flour, cocoa powder, baking powder, baking soda, and salt until evenly combined.
Step 4: Beat the Eggs
Using an electric mixer, beat the eggs and sugar for 5–7 minutes until pale, thick, and fluffy.
Step 5: Add Wet Ingredients
Mix in the vegetable oil, milk, and vanilla extract until smooth.
Step 6: Combine Everything
Gradually fold the dry ingredients into the wet mixture. Stir gently until no dry flour remains. Avoid overmixing to keep the cake light.
Step 7: Fill the Pan
Pour the batter into the prepared cake pan and tap it gently on the counter to remove large air bubbles.
Step 8: Steam the Cake
Cover the pan loosely with aluminum foil to prevent water droplets from falling onto the cake.
Place the pan into the steamer.
Steam over medium heat for 45–50 minutes, or until a toothpick inserted into the center comes out clean.
Step 9: Cool
Remove the cake carefully from the steamer.
Allow it to cool in the pan for 10 minutes before transferring it to a wire rack.
Slice and enjoy.
