4tablespoonsunsalted butter
1/3cupbrown sugar
2blood oranges, rinds removed* and thinly sliced
Cake:
1cupall-purpose flour
1/2cupalmond flour (or another 1/2 cup all-purpose flour)
2teaspoonsbaking powder
Pinch of salt
3/4cupsugar
Grated zest of 1 blood orange
1/2cupplain Greek yogurt
3largeeggs
1/2teaspoonalmond extract
1/2cupextra-virgin olive oil
Instructions
For the Blood Orange Topping (do this first):
In a microwave-safe bowl or a saucepan on the stove, melt the butter. Whisk in the sugar until it melts. Pour the mixture into the bottom of a greased 9-inch round cake pan. Arrange the orange slices on top of the mixture, overlapping slightly, in a spiral pattern. You may wind up not using all the orange slices, depending on their size. Have a snack.
For the Cake:
Preheat the oven to 350 degrees F. In a large bowl, whisk together the flour, almond flour, baking powder, and salt.
In a medium bowl, place the sugar and orange zest and rub them together with your fingers until the sugar smells fragrantly orange. This releases the oils in the zest and flavors the cake.
Add the yogurt, eggs, olive oil, and almond extract to the sugar and whisk vigorously until the mixture is very well blended. Whisk some more for good measure.
Add the dry ingredients, and fold and stir them in with a wooden spoon until fully blended and the batter is smooth and thick.
Pour the batter over the orange slices in the cake pan and bake for 35-40 minutes, or until the cake is golden brown and beginning to come away from the pan. A knife or toothpick inserted in the center should come out clean.
Let the pan cool on a rack for 5 minutes, then run a knife or thin spatula around the edges of the cake. Place a large plate over the pan, then flip so the cake comes out upside-down onto the plate.
Let cool to room temperature. Serve alone or with whipped cream. Cake will keep, well-wrapped at room temperature, for 3-4 days.
Notes
*I did not remove the orange rind when taking pictures of this cake because it's prettier that way, but the rinds impart a slightly bitter flavor, so I'd recommend removing them.Cake recipe adapted from Dorie Greenspan's French Yogurt Cake in Baking: From My Home to Yours.
