Preheat the oven at 350 degrees F (180 C)

In a large bowl cream the olive oil and the sugars.

Add the eggs one by one and mix well.

Add the rest of the wet ingredients (orange juice and or brandy) and mix well.

Ina smaller bowl, mix the flour with the baking powder, baking soda and cinnamon.

Add the flour mixture to the olive oil mixture and mix just enough so that the flour has been blended in.

Add the walnuts and chocolate chips and mix until they are spread throughout the whole batter.

Pour batter in a 9 inch springform pan (in this photo I had used an 8 inch, which was a bit small hence the dome).

Bake for about 35-40 minutes until a toothpick inserted in the cake comes out clean.

Let it cool, and dust with powdered sugar.
