Portuguese Orange Olive Oil Cake

Method

1. Position a rack in the middle of the oven, remove any racks above it, and crank up the heat to 350°F (180°C). Coat your tube pan with baking spray and set aside.
2. Finely grate the zest of 3 oranges and then squeeze the juice from them. You should have 1 cup of orange juice; if not, squeeze the 4th orange
3. In a large bowl, whisk together the flour, baking powder, and salt.
4. In the bowl of a stand mixer fitted with a paddle attachment or with a handheld mixer in a large bowl, beat the eggs on medium-high speed until well combined, about 1 minute. Slowly pour in the granulated sugar and continue to beat until thick and pale yellow, about 3 minutes.
5. Switch to low speed and alternate adding the flour mixture and the oil, starting and ending with the flour and beating until just a few wisps of flour remain. Add the zest and slowly drizzle in the orange juice, with the mixer on its lowest setting, to bring the batter together.
6. Gently scrape the batter into the prepared pan and bake until a cake tester comes out with a few moist crumbs clinging to it, about 40 min to an hour. Check the cake occasionally and if the top begins to brown a touch too much, loosely cover it with foil.
7. When the cake is done, place the pan on a wire rack and let the cake cool in the pan for 15 minutes. (Don’t forget to come back after 15 minutes. Seriously. If the cake remains in the pan too long, the sugars begin to cool and stick to the pan.)
8. Turn the cake out onto the wire rack and let it cool completely. (We know. Resist the temptation.) Place the cake on a covered cake stand and let it sit overnight. (Seriously. This dense, moist, fruity cake only gets better with age. Don’t even think about taking a bite until the day after you make it—or even the day after that.) Just before serving, dust with confectioners’ sugar.
