Light, soft, and deeply chocolatey, this vegan chocolate sponge base is the perfect foundation for cakes, layered desserts, cupcakes, and celebration bakes. It has a tender crumb, rich cocoa flavor, and stays wonderfully moist without eggs or dairy.
Can This Recipe Support Weight Loss Goals?
This chocolate sponge can fit into a balanced eating plan when enjoyed in a moderate portion. Using unsweetened cocoa and plant-based ingredients keeps the recipe simple, while portion size remains important because cake is still a calorie-dense dessert.
Does This Recipe Fit a High-Protein Lifestyle?
This sponge provides a modest amount of plant-based protein from the flour and plant milk. For a more protein-focused dessert, pair it with a high-protein vegan yogurt or soy-based chocolate filling. Using soy milk can also provide more protein than many other plant milks.

Short Introduction
This vegan chocolate sponge is soft, moist, and packed with rich cocoa flavor.
Plant milk and a simple egg-free technique create a beautifully tender crumb.
Use it as a base for layered cakes, trifles, cupcakes, or your favorite chocolate dessert.
📝 Ingredients
- 1½ cups all-purpose flour
- ½ cup unsweetened cocoa powder
- ¾ cup granulated sugar
- 1 teaspoon baking soda
- 1 teaspoon baking powder
- ½ teaspoon salt
- 1 cup unsweetened plant milk
- ⅓ cup neutral vegetable oil
- 1 tablespoon apple cider vinegar
- 2 teaspoons vanilla extract
- ½ cup hot water or hot brewed coffee
Note: Coffee does not make the cake taste like coffee; it simply intensifies the chocolate flavor. Use hot water if preferred.
Directions
- Preheat the oven.
Preheat your oven to 350°F (175°C). Grease an 8-inch round cake pan and line the bottom with parchment paper. - Combine the dry ingredients.
In a large bowl, whisk together flour, cocoa powder, sugar, baking soda, baking powder, and salt. - Prepare the wet ingredients.
In a separate bowl, whisk together plant milk, vegetable oil, apple cider vinegar, and vanilla. - Combine wet and dry ingredients.
Pour the wet mixture into the dry ingredients. Whisk gently until just combined, about 20–30 seconds. - Add the hot liquid.
Slowly pour in the hot water or coffee while whisking gently. The batter will become fairly thin—this is normal. - Transfer to the pan.
Pour the batter into the prepared cake pan and gently tap the pan once or twice to release large air bubbles. - Bake.
Place in the center of the oven and bake at 350°F (175°C) for 25–30 minutes. - Check for doneness.
Insert a toothpick into the center. It should come out clean or with a few moist crumbs. - Cool.
Let the cake cool in the pan for 10 minutes, then carefully remove it and transfer it to a wire rack. - Cool completely.
Allow the sponge to cool for at least 45–60 minutes before slicing or decorating. - Use as a cake base.
Slice horizontally into layers or use the whole sponge as the base for your favorite vegan frosting and filling.
Vegan Baking Tips
- Use unsweetened soy milk for a more protein-rich option.
- Don’t overmix once the flour is added.
- The hot liquid helps bloom the cocoa and creates a moist crumb.
- Use room-temperature ingredients when possible.
- For neat cake layers, chill the completely cooled sponge for 30–60 minutes before slicing.
