I love summer time. I love the sunshine. I do not enjoy winter time or the very short days we have. When it gets dark at 4pm, my body seems to think it’s time to crawl into bed at 7pm.

The one thing that takes these winter blues away is the knowledge that it is citrus season. The family fruit bowl is filled to the brim with oranges, tangerines and grapefruits. Those happy fruits put a smile on my face and brighten our short days.

Why this recipe is so awesome

I have a weakness for desserts, especially cakes and cookies. I totally go ga-ga for fruity desserts (although chocolate isn’t too far behind). I am still plowing through my endless supply of Valencia oranges from our visit to an orange grove, and an upside down orange cake was calling my name.

This cake is really, REALLY simple. It’s easy to mix together and assemble. The cake batter uses extra virgin olive oil – don’t let that scare you. I share why I love to bake with olive oil here.

By using thin-skinned Valencia oranges, you don’t have to remove the peel. The result is some delicious orange caramelizing goodness on the bottom of the cast-iron skillet.

There is orange flavor all throughout the cake and not just with the fruit on the bottom. I use orange juice and orange zest in the cake batter. The result is a fluffy and moist orange cake topped (once inverted) with caramelized orange slices.

Orange heaven…

Ingredients you need

• Oranges: Orange slices line the bottom of the pan. If you use Valencia oranges you can leave the peel on as it has very little pith (white part), which tastes bitter. If you are using a thick skinned orange, remove the skin and pith from your rounds. The batter also uses orange juice and orange zest, so bring on the oranges!
• Extra virgin olive oil: You should also taste your olive oil alone to make sure it isn’t rancid. Olive oils come in a range of flavor profiles, from pungent to mild. I suggest choosing a mild or buttery olive oil for this cake.
• Butter: The cake is baked with olive oil, but I use butter for the bottom of the pan to caramelize the brown sugar and orange slices.
• Greek yogurt: I love baking with yogurt because it makes my cakes so fluffy and moist. You can also use sour cream instead.
• Pantry staples: brown sugar (light or dark, granulated sugar, all purpose flour, baking powder, salt
• Eggs

Step-by-step directions

1. Using a 9-inch cast iron skillet, heat over medium-high heat and melt butter. When butter is bubbling and just starts to brown, stir in brown sugar. Cook until sugar has dissolved into the butter and starts to melt, then remove from heat. Spread sugar mixture evenly across the bottom of the pan.

2. Remove pan from heat. Arrange thinly sliced oranges over the brown sugar into desired pattern and set aside.

3. In a medium-sized bowl whisk together flour, baking powder and salt.

4. In a large bowl, mix together sugar, yogurt, orange juice, orange zest, olive oil and eggs until combined.

5. In batches, mix flour mixture into yogurt mixture and stir until combined.

6. Pour cake batter evenly over the orange slices in your cast iron pan.

7. Place cake in the oven and bake at 350ºF for 30 minutes, or until a toothpick inserted into the center of the cake comes out clean. Allow cake to cool for 10 minutes in the pan.

8. Run a knife blade along the sides of the cake to insure a clean removal. Place serving plate over the cast iron skillet and carefully invert the cake. Keep the skillet on the plate until the cake falls into the plate. Remove skillet and allow cake to cool to room temperature, about 1 hour before serving.
