Ingredients

For the Cake:

200g (1 ¾ cups) all-purpose flour
1 ½ teaspoons baking powder
½ teaspoon baking soda
¼ teaspoon salt
150g (¾ cup) granulated sugar
115g (½ cup) unsalted butter, softened
2 large eggs
1 teaspoon vanilla extract
120ml (½ cup) whole milk
2 tablespoons vegetable oil

For the Chocolate Swirl:

2 tablespoons unsweetened cocoa powder
2 tablespoons hot water

Instructions

Step 1: Prepare the Batter

Preheat the oven to 175°C (350°F). Grease and line a loaf pan with parchment paper.
In a bowl, whisk together the flour, baking powder, baking soda, and salt. Set aside.
In a separate large bowl, beat the butter and sugar until light and fluffy, about 2-3 minutes.
Add the eggs, one at a time, beating well after each addition. Mix in the vanilla extract.
Gradually add the dry ingredients to the wet ingredients, alternating with the milk and oil. Mix until just combined.

Step 2: Create the Chocolate Swirl

In a small bowl, mix the cocoa powder with hot water to form a smooth paste.
Take ⅓ of the vanilla batter and mix it with the cocoa paste until fully combined.

Step 3: Assemble the Marble Cake

Pour half of the vanilla batter into the prepared loaf pan.
Add the chocolate batter on top, then the remaining vanilla batter.
Use a knife or skewer to gently swirl the batters together, creating a marbled effect.

Step 4: Bake and Cool

Bake for 45-50 minutes, or until a toothpick inserted in the center comes out clean.
Let the cake cool in the pan for 10 minutes, then transfer to a wire rack to cool completely.

Tips for the Best Marble Loaf Cake

Don’t Overmix the Batter: Overmixing can make the cake dense instead of soft and fluffy.
Use Room Temperature Ingredients: This helps create a smoother batter and even baking.
Swirl Gently: Use a knife or skewer to create light swirls—don’t overmix, or you’ll lose the marbled effect.
Store Properly: Keep in an airtight container at room temperature for up to 3 days, or refrigerate for up to a week.
