Ingredients You’ll Need
The ingredients for this Chocolate Sponge Cake Loaf Recipe are straightforward yet carefully chosen to create a tender crumb, deep chocolate flavor, and beautiful color. Each component plays a vital role in achieving that perfect balance between softness and richness.
- 1½ cups (190g) all-purpose flour: Provides the structure for the cake while keeping it light.
- ½ cup (60g) cocoa powder: Gives the cake its rich chocolate flavor and deep color.
- 1 cup (200g) sugar: Sweetens the cake while helping with moisture retention.
- 1 teaspoon baking powder: A leavening agent that ensures the cake is fluffy and rises well.
- ½ teaspoon baking soda: Works with the baking powder to provide extra lift and height.
- ¼ teaspoon salt: Enhances the chocolate flavor and balances sweetness.
- ¾ cup (180ml) vegetable oil: Keeps the cake moist and tender without making it heavy.
- ¾ cup (180ml) warm milk: Adds moisture and helps activate the leavening agents.
- 3 large eggs: Contribute richness, structure, and a light texture.
- 1 teaspoon vanilla extract: Adds a subtle sweetness and depth to the chocolate.
- 2 tablespoons warm water (optional): Gives the batter a lighter, airier texture.
How to Make Chocolate Sponge Cake Loaf Recipe
Step 1: Prepare Your Oven and Pan
Start by preheating your oven to 170°C (340°F). While the oven is warming up, grease your loaf pan thoroughly and line it with parchment paper. This step ensures your cake won’t stick and will come out perfectly smooth on all sides.
Step 2: Mix the Dry Ingredients
In a large bowl, whisk together the all-purpose flour, cocoa powder, baking powder, baking soda, salt, and sugar. Whisking well at this stage means even distribution of ingredients, which is key to a uniform rise and chocolatey flavor in every bite.
Step 3: Combine the Wet Ingredients
In another bowl, beat the eggs first, then add the vegetable oil, warm milk, vanilla extract, and warm water if you’re using it. Mix these gently but thoroughly until everything is well combined. Incorporating the wet ingredients encourages a smooth batter that helps achieve the cake’s light and fluffy texture.
Step 4: Bring It All Together
Pour the wet ingredient mixture into the dry ingredients and fold them together gently. It’s important to whisk until the batter is smooth with no lumps, but be careful not to overmix as this could make the cake dense rather than soft.
Step 5: Bake to Perfection
Transfer the batter to your prepared loaf pan. Give the pan a gentle tap on the counter to release any air bubbles trapped in the batter. Place the pan into your oven and bake for 35 to 45 minutes. You’ll know the cake is ready when a toothpick inserted in the center comes out clean. This is the heart of the Chocolate Sponge Cake Loaf Recipe, and the aroma filling your kitchen will be simply irresistible.
Step 6: Cool and Slice
Allow the cake to cool in the loaf pan for about 10 minutes, then carefully remove it and transfer it to a wire rack to cool completely. This cooling step is essential for setting the perfect crumb before slicing.
How to Serve Chocolate Sponge Cake Loaf Recipe

Garnishes
This chocolate sponge cake loaf shines on its own, but if you want to jazz it up, try dusting it with powdered sugar or cocoa powder. A dollop of whipped cream or a drizzle of chocolate ganache adds elegance and extra indulgence for special occasions.
Side Dishes
Pair your slices with fresh berries like raspberries or strawberries to add a burst of freshness that perfectly complements the rich chocolate flavor. A scoop of vanilla ice cream or a spoonful of mascarpone can also balance the cake’s sweetness, making every bite a delightful experience.
Creative Ways to Present
Serve slices stacked with layers of jam or Nutella spread in between for a decadent twist. Alternatively, cut the loaf into thick sticks and serve as a dippable treat alongside a warm cup of coffee or hot chocolate for cozy afternoons.
Make Ahead and Storage
Storing Leftovers
This loaf keeps beautifully in an airtight container at room temperature for 2 to 3 days. You can also refrigerate it for up to a week, but bring it to room temperature before serving to enjoy its lovely sponge texture.
Freezing
If you want to keep your cake fresh for longer, wrap the cooled loaf tightly in plastic wrap and place it in a freezer-safe bag or container. The Chocolate Sponge Cake Loaf Recipe freezes well for up to 2 months. Thaw it overnight in the fridge before enjoying.
Reheating
To refresh slices, warm them in a microwave for 15 to 20 seconds or in a low oven (150°C/300°F) for about 10 minutes. This will revive the softness and bring out the rich chocolate aroma beautifully.
FAQs
Can I use butter instead of vegetable oil?
Yes! You can substitute melted butter for vegetable oil in equal amounts. Butter will add a richer flavor but might result in a slightly denser texture compared to the lightness that oil offers.
What if I don’t have cocoa powder?
You can’t really replicate that authentic chocolate sponge loaf without cocoa powder, but for a vanilla sponge loaf, simply omit it and add an extra tablespoon of flour. The flavor will be different but still delicious.
Can I add chocolate chips or nuts?
Absolutely! Adding chocolate chips or chopped nuts like walnuts or almonds can give the cake delightful bursts of texture and flavor. Fold them gently into the batter before baking.
Why is my chocolate sponge cake loaf dense?
Dense sponge cakes usually come from overmixing the batter or using too much flour. Be gentle when combining wet and dry ingredients and measure carefully to keep the cake light and airy.
Is this recipe suitable for beginners?
Definitely! The Chocolate Sponge Cake Loaf Recipe is straightforward and forgiving, making it an excellent choice for bakers of any skill level looking to create a delicious homemade dessert.
