Add the eggs, one at a time and continue whisking for 2-3 minutes.

Add the flour mix and and continue to mix with a spatula.

Separate the batter into two different bowls.

In the one bowl sift in the cocoa powder, and add the chocolate chips.

In the other add the walnuts and the pumpkin mush.

In a baking tray 20x20cm place at the bottom a piece of baking paper, and brush with butter (and the sides of the baking tray).

Take spoonfuls of each mixture (using a different spoon for every batter), and place them in the baking tray.

With a knife stir the mixture in every direction to create a marble effect.

Bake in a preheated oven in 180oC for 50 to 60 minutes.
