With an ice cream scoop, pour 3 tbsp (45 ml) of the chocolate batter in the centre of the springform pan and allow it to spread for about 20 seconds. With the second ice cream scoop, pour the same amount of vanilla batter in the centre of the chocolate batter. Again, allow to spread for about 20 seconds. Repeat these two steps alternately until all the batter has been used. Bake for about 1 hour 10 minutes or until a toothpick inserted in the centre of the cake comes out clean. Let cool. Unmould from the pan and cool completely on a wire rack.
