Mix together the flour, sugar and baking powder in a large bowl. Add the oil, vanilla and eggs and stir together. Toss in the add ins and combine with your hands. Form the dough into 3 to 4 loaves, depending on how big you want your cookies to be. (I do 4 loaves.) Place the loaves on parchment paper on a cookie sheet and sprinkle with cinnamon sugar.
Bake until golden brown, about 40 minutes. Allow to cool for 10 to 15 minutes, then slice on the bias. If you prefer traditional biscotti, after slicing, lay them flat on the cookie sheet. Reduce the oven temperature to 300 degrees F and continue to bake for another 10 to 15 minutes.
