You’re going to flip over this homemade Citrus Upside-Down Sheet Cake that’s ooey-gooey, tender and buttery!

With the amount of citrus filling the bins at the super market these days, I couldn’t resist making this colorful fruit the star of today’s show! Blood oranges, navel oranges, ruby red grapefruits, clementines….so many gorgeous choices!
Question: Have you noticed lately all of the beautiful upside-down cakes, especially citrus, occupying the inter-webs? They’re making me pine for upside-down cake!
It’s been forever since I’ve made pineapple upside-down cake. It. was. time!

INGREDIENTS FOR CITRUS UPSIDE-DOWN SHEET CAKE:
-
- Unsalted butter
- Light brown sugar
- Oranges and grapefruit (I used blood oranges, ruby red grapefruits and navel oranges)
- All-purpose flour
- Granulated sugar
- Baking powder
- Baking soda
- Salt
- Ground cinnamon
- Eggs
- Buttermilk
- Vegetable oil
- Vanilla extract

DIRECTIONS FOR MAKING THIS CAKE:
- Preheat oven to 350 degrees and prepare a 13 x 9 metal baking pan with nonstick baking spray and flour.
- For the topping (which is actually the bottom of the cake while baking): Pour melted butter in the prepared pan. Evenly sprinkle with brown sugar and then arrange peeled citrus slices on the brown sugar.
- For the cake: In a large bowl, whisk together the flour, sugar, baking powder, baking soda, salt and cinnamon.
- Add eggs, buttermilk, oil, and vanilla to the flour mixture.
- Using an electric mixer on medium-low speed, beat for 1 minute until blended. Scrape sides and bottom of bowl with a spatula. Beat on medium speed for 1 more minute.
- Carefully pour batter over citrus and spread evenly.
- Bake in preheated oven for 50 to 60 minutes until a toothpick inserted in the center comes out with a few moist crumbs attached.
- Immediately run a knife around edge of pan.
- Place a large platter over pan and, pressing platter and pan together, invert cake onto platter (I used the bottom side of a cookie sheet). Replace any topping that may have stuck to the pan.
- Let cool for 15 minutes and serve warm, or cool completely and serve at room temperature.

COOK’S NOTES:
- When readying the citrus, it’s easiest to slice the fruit with the peel on, then gently remove the peel and pith by cutting it off with a knife.
- Don’t be afraid to show the cake who’s boss when it comes time to flipping (after baking). Gentle but assertive is the name of the flipping game!
- I used different citrus for the purpose of color, but feel free to use [any] one or more of your favorites.
- This cake lives up to its ooey-gooey nature; so if you like tender brown-sugary delicious crumb – you’ve come to the right place!
- This upside-down cake will look beautiful on your holiday brunch table! #Easteriscoming

Sweet. Tart. Ooey. Gooey. Delicious….worth repeating. 😉
