How to cook deliciously - Marmorkuchen (German Marble Cake)

1 . Stage

Preheat the oven to 350 degrees F (175 degrees C). Grease a large Kugelhopf or Bundt® cake pan with butter.

2 . Stage

Beat butter with an electric mixer in a large bowl until light and creamy. Slowly add sugar and vanilla sugar while beating constantly. Add eggs, 1 at a time, beating well after each addition. Beat for 5 minutes until batter is light and fluffy.

3 . Stage

Sift flour and baking powder together in a separate bowl. Gradually mix flour mixture into the cake batter, alternating with the milk. Add rum and lemon zest. Pour 2/3 of the batter into the prepared pan.

4 . Stage

Stir cocoa powder into the remaining batter until fully incorporated. Pour chocolate batter over the vanilla batter in the pan. Gently move a knife up and down through the batter in circular movements to create a marbled effect.

5 . Stage

Bake cake in the preheated oven until a toothpick inserted in the center comes out clean, 50 to 60 minutes. Let cool slightly in the pan. Remove and place on a cooling rack to cool completely.
