Ingredients

For the Cake:

1 cup (230 g) unsalted butter, softened
1 ½ cups (300 g) granulated sugar
4 large eggs, at room temperature
2 teaspoons pure vanilla extract
2 cups (250 g) all-purpose flour
1 teaspoon baking powder
¼ teaspoon salt
½ cup (120 ml) whole milk
2 tablespoons unsweetened cocoa powder
2 tablespoons boiling water (for the chocolate batter)

Optional Toppings:

Powdered sugar for dusting
Chocolate ganache or glaze
Fresh berries or whipped cream

Cooking Directions

Preheat the Oven:
Preheat your oven to 350°F (175°C). Grease and flour a 9×5-inch loaf pan or line it with parchment paper.
Cream Butter and Sugar:
In a large bowl, beat the softened butter and sugar together until light and fluffy, about 3–4 minutes.
Add Eggs and Vanilla:
Beat in the eggs one at a time, mixing well after each addition. Stir in the vanilla extract.
Combine Dry Ingredients:
In a separate bowl, whisk together flour, baking powder, and salt.
Mix Wet and Dry Ingredients:
Gradually add the dry mixture to the creamed butter mixture, alternating with milk. Begin and end with the flour mixture. Mix until just combined.
Prepare Chocolate Batter:
In a small bowl, mix cocoa powder with boiling water to make a smooth paste. Take about 1 cup of the batter and stir it into the cocoa paste to create the chocolate batter.
Create the Marble Effect:
Spoon half of the vanilla batter into the loaf pan, then spoon the chocolate batter over it. Top with the remaining vanilla batter. Swirl gently with a knife or skewer to create a marbled pattern — do not overmix.
Bake:
Bake for 55–65 minutes, or until a toothpick inserted into the center comes out clean.
Cool the Cake:
Let the cake cool in the pan for 10 minutes, then transfer to a wire rack to cool completely before slicing.
