Ingredients
2 cups all-purpose flour
1 cup granulated sugar
2 teaspoons baking powder
¼ teaspoon salt
3 large eggs, room temperature
¾ cup vegetable oil
1 cup milk
2 teaspoons vanilla extract
Chocolate Swirl Ingredients
2 tablespoons cocoa powder
2 tablespoons hot milk or hot water
1 tablespoon sugar (optional, for a sweeter chocolate flavor)
Instructions
Prepare the Oven and Pan
Preheat your oven to 170°C / 340°F. Grease and line an 8-inch round cake pan or a standard loaf pan with parchment paper to ensure easy removal after baking.
Mix the Dry Ingredients
In a large mixing bowl, whisk together the flour, sugar, baking powder, and salt until evenly combined. This helps the cake rise evenly and prevents lumps.
Combine the Wet Ingredients
In a separate bowl, whisk the eggs, vegetable oil, milk, and vanilla extract until smooth and well blended. Using room-temperature eggs helps create a softer, more even texture.
Make the Cake Batter
Pour the wet ingredients into the bowl of dry ingredients and mix gently until just combined. Do not overmix, as this can make the cake dense instead of soft and fluffy.
Create the Marble Effect
Divide the batter evenly into two bowls. In a small cup, mix the cocoa powder with hot milk or hot water until smooth, adding sugar if desired. Stir this chocolate mixture into one bowl of batter. Spoon the vanilla and chocolate batters alternately into the prepared pan, then gently swirl with a knife or skewer to create a marble pattern. Avoid over-swirling to keep the colors distinct.
Bake
Bake for 40–45 minutes, or until a toothpick inserted into the center comes out clean. Baking times may vary slightly depending on your oven and pan type.
Cool and Serve
Allow the cake to cool in the pan for 10 minutes, then transfer to a wire rack to cool completely before slicing. This helps the cake set and keeps it from crumbling.
Baking Tips for Best Results
Use full-fat milk for a richer, more tender crumb.
Do not overmix the batter after adding the flour to keep the cake light.
For extra flavor, add a pinch of cinnamon or a splash of coffee to the chocolate batter.
This cake stores well at room temperature for up to 3 days when wrapped tightly.
