Make the crust: In a large bowl, with an electric mixer, blend together the flour, confectioners' sugar, butter and orange zest until crumbly. Mix lightly with floured hands, press the mixture evenly into the bottom of a greased 9 x 13-inch pan. Bake 20-25 minutes until lightly browned.

Meanwhile make the topping: In a large bowl, lightly beat the eggs. Mix in the granulated sugar, flour, baking powder, orange juice and sour cream. Set aside until crust is done.

Remove crust from oven. Quickly remix the orange topping and pour it over the warm crust. Return to oven and bake 25-30 minutes until topping is a light golden brown. Let cool. Just before serving, sprinkle with confectioners' sugar through a strainer.
