Heat the oven to 360°F (180 °C). In a mixing bowl, put 1 egg + 1 yolk , the softened butter, sugar, vanilla sugar and whip until gray in color.
Then add the oil, milk , 5 tablespoons orange juice, grated orange rind. Mix everything with a mixer on medium speed, then add the sifted flour mixed with the baking powder and knead a soft dough by hand.
