This marble bundt cake is a classic Italian breakfast cake called Ciambella Marmorizzata. The batter is made with simple ingredients you certainly have at home: flour, sugar, eggs, milk, butter, and baking powder. Half is flavored with vanilla and half with cocoa creating a nice black-and-white effect.

Notes
Remove the butter from the fridge for at least one hour before starting. The butter should be at room temperature, and it cannot be melted
Instead of making two different batters, I make one batch, then separate them into two to make the two different flavors.
If you want a marble effect, pour only half of the vanilla batter, then the chocolate and the rest of the vanilla at the end.
The cooking time is linked to the amount of batter. If you make half a cake, the baking time will be less. To check when the cake is cooked, pierce it with a metal skewer. The cake is cooked when the skewer comes out clean.
Wait 10 minutes to cool down before removing the cake from the pan. If you remove it when it is too hot, the cake may break.
