Ingredients

(Tip: You’ll find the full list of ingredients and measurements in the recipe card below.)

• 200 g unsalted butter, softened
• 200 g granulated sugar
• 200 g all-purpose flour
• 4 large eggs
• 1 packet baking powder, about 11 g
• 1 packet vanilla sugar, about 7.5 g
• 2 tablespoons unsweetened cocoa powder
• butter for greasing the pan
• a small amount of flour for dusting the pan, optional

Directions

Preheat your oven to 180°C (350°F). Grease a loaf pan with butter and lightly dust with flour if needed.

In a large bowl, cream the softened butter with the sugar and vanilla sugar until light and creamy.

Add the eggs one at a time, mixing well after each addition.

Gradually add the flour and baking powder, mixing until a smooth and homogeneous batter forms.

Divide the batter evenly into two separate bowls.

Add the unsweetened cocoa powder to one portion and mix well.

Pour part of the plain batter into the loaf pan. Add the chocolate batter in the center, then top with the remaining plain batter.

Gently run a knife through the batter to create a marbled effect without overmixing.

Bake for 40 to 45 minutes.

Check for doneness by inserting a knife into the center. It should come out clean.

Let the cake cool for a few minutes in the pan, then transfer to a wire rack to cool completely.
