Ingredients
Butter (to grease pan)
2 cups all-purpose flour
1.5 teaspoons baking powder
1/4 teaspoon salt
1/2 cup extra virgin olive oil
1 cup sugar
4 eggs, separated
1/3 cup freshly squeezed orange juice
2 teaspoons grated orange zest
Steps
- Preheat oven to 350 degrees. Grease 9 x 13 inch pan. Combine flour, baking powder, and salt in a bowl and set aside.
- Use electric mixer to beat olive oil with 3/4 cup of the sugar until creamy. Add egg yolks and beat until thick.
- Mix in the dry ingredients (flour, baking powder, salt) until smooth. Stir in orange juice and zest.
- In separate bowl, beat egg whites until foamy, then mix in remaining 1/4 cup of sugar and beat until it has soft peaks[1]. Then stir eggs whites into batter, which is going to be very thick.
- Pour into pan and bake for 35 minutes, or until toothpick comes out clean. Let cool for 15 minutes.
- Frost or glaze as you like.[2]
[2] I say as you like, particularly, because I underestimated my abilities and made a pretty lame sugar & milk based frosting. Mostly, I would say don't over do it, if you want to appreciate the olive oil and orange flavors.
