4 eggs, separated
1 teaspoon vanilla extract
1 cup sugar
1/4 cup firmly packed light brown sugar
3/4 cup olive oil
3 1/3 cups flour
1 heaping teaspoon baking powder
Zest of 1 orange
1 cup freshly squeezed orange juice (Kiros suggests 4 oranges, but I found 3 to be sufficient)
1/2 cup pine nuts
Recipe
Preheat the oven to 350, grease 2 8 1/2 inch springform pans with olive oil and flour. Whip the egg whites until they're firm, then whip the yolks with the vanilla until they attain some body and become foamy. Whisk in the sugars, then gradually add the olive oil, mixing well. Add the flour, baking powder, orange zest and juice and beat until the batter becomes smooth. Gently fold in the egg whites.
Divide the batter between the two pans and sprinkle the top of each with the pine nuts. Bake for 35 minutes or until the tops are golden brown and a toothpick comes out clean. Allow to cool before serving.
