Ingredients
For the Sponge Cake
- 1½ cups (190 g) all-purpose flour
- ¾ cup (150 g) granulated sugar
- 4 large eggs, room temperature
- ¼ cup (60 ml) neutral oil
- ¼ cup (60 ml) milk
- 1 teaspoon vanilla extract
- 1 teaspoon baking powder
- Pinch of salt
- 1 tablespoon instant coffee
- 1 tablespoon hot water

Instructions
1. Prepare the Coffee Mixture
Place the instant coffee in a small bowl.
Add 1 tablespoon hot water and stir until the coffee is completely dissolved.
Set aside to cool slightly.
2. Prepare the Pan and Oven
Preheat the oven to 350°F (175°C).
Grease an 8-inch round cake pan and line the bottom with parchment paper.
Lightly dust the sides with flour or use baking spray.
Set aside.
3. Prepare the Dry Ingredients
In a medium bowl, whisk together the flour, baking powder, and salt.
Set aside.
4. Beat the Eggs and Sugar
Place the eggs and sugar in a large mixing bowl.
Using an electric mixer, beat on medium-high speed for approximately 5–7 minutes, until the mixture becomes pale, thick, and significantly increased in volume.
This is an important step because the whipped eggs provide much of the cake’s light sponge texture.
5. Add the Oil, Milk, and Vanilla
Reduce the mixer speed to low.
Slowly add the oil, milk, and vanilla extract.
Mix just until incorporated.
Don’t overmix at this stage.
6. Fold in the Flour
Sift the flour mixture over the egg mixture in two or three additions.
Using a silicone spatula, gently fold the flour into the batter with broad, sweeping motions.
Continue just until no dry flour remains.
Be careful not to deflate the whipped eggs.
7. Divide the Batter
Pour approximately two-thirds of the batter into a separate bowl.
Leave the remaining one-third in the original bowl.
8. Add the Coffee
Pour the dissolved coffee mixture into the smaller portion of batter.
Gently fold until evenly incorporated.
The coffee batter should become a light mocha color.
9. Create the Marble Effect
Pour alternating spoonfuls of the vanilla and coffee batters into the prepared cake pan.
You can create layers or random patches.
Once all the batter is in the pan, insert a skewer or thin knife into the batter and make a few gentle swirls.
Do not over-swirl, or the two colors will blend together instead of creating a distinct marble pattern.
10. Bake
Place the cake in the preheated oven.
Bake for approximately 35–40 minutes, or until a toothpick inserted into the center comes out clean or with a few moist crumbs.
Avoid opening the oven during the first 25 minutes, as a sudden temperature change can cause the sponge to collapse.
11. Cool the Cake
Remove the cake from the oven and allow it to cool in the pan for 10 minutes.
Run a thin knife around the edges, then carefully turn the cake onto a wire rack.
Remove the parchment paper and allow the cake to cool completely.
12. Decorate and Serve
Once completely cool, dust lightly with powdered sugar.
For a more indulgent dessert, drizzle with chocolate glaze or decorate with whipped cream and chocolate shavings.
Slice with a sharp serrated knife and serve with coffee or tea.
Chef’s Tips
- Use room-temperature eggs: They whip to a greater volume than cold eggs.
- Beat the eggs well: This is key to achieving a light sponge.
- Fold gently: Overmixing can knock out the air and produce a dense cake.
- Sift the flour: This makes it easier to incorporate without overmixing.
- Don’t over-swirl: A few gentle strokes create a much prettier marble effect.
- Don’t overbake: Too much baking can dry out the delicate sponge.
- Cool before decorating: Warm cake can cause powdered sugar or frosting to melt.
Flavor Variations
Mocha Marble Cake
Add 1 tablespoon cocoa powder to the coffee batter for a deeper chocolate-coffee flavor.
Chocolate Coffee Cake
Replace 2 tablespoons of flour with 2 tablespoons unsweetened cocoa powder in the main batter.
Coffee Cream Cake
Slice the cooled cake horizontally and fill with lightly sweetened whipped cream flavored with instant coffee.
Chocolate Glazed Coffee Cake
Pour a simple dark chocolate ganache over the cooled cake and let it set before slicing.

Add ½ teaspoon hazelnut extract or sprinkle chopped toasted hazelnuts over the finished cake.
