If you love oranges then you'll love this Orange Upside-Down Cake. The cake is a delicious cornmeal buttermilk cake flavored with orange zest and fresh thyme topped with a beautiful spiral of fresh orange slices which are candied during the baking process. It's irresistibly delicious, flavorful and a great dessert to serve to family and friends.
Why This Recipe Tastes So Good
Upside-down cakes are always delicious and this orange upside-down cake is not exception. Caramelized fruit on top of a soft moist cake is a great combination. Oranges make a great fruit upside-down cake and the slight bitterness of the candied orange peel tastes great on this cake. The cake is made with fresh orange zest and thyme which makes for a great floral combination with the oranges. Top the servings with whipped creme fraiche and enjoy.
Orange Upside-Down Cake Ingredients
This recipe is based on my Meyer Lemon Upside-Down Cake, but for this orange version, I used orange zest and fresh thyme to flavor the cake and to complement the oranges on top.
This Orange Upside-Down Cake has the following ingredients:
- Cara Cara or Navel Oranges. I used Cara Cara oranges because of their sweetness and unique taste, but regular navel oranges will work in this recipe.
- Granulated Sugar. Sugar is in the topping to candy the oranges as they bake and provide moisture for the cake
- Unsalted Butter. I prefer unsalted butter to control the salt in the recipe. If you use salted butter, reduce the salt in the topping and in the cake batter by half.
- All-Purpose Flour. AP flour provides structure for the cake.
- Cornmeal. Cornmeal adds a slice crunch to the cake and slight corn flavor that goes well with the oranges.
- Buttermilk. Provides moisture, fat, and flavor. If you don't have buttermilk you can make your own using milk and lemon (or vinegar).
- Orange Zest. Adds a flavor punch to the cake.
- Fresh Thyme. The fresh thyme adds a nice herbal flavor to the cake that pairs well with the sweetness of the cake and the oranges.
- Baking Soda and Baking Powder. These are the chemical leaveners that provide lift to the cake. If it's been a while since you've used your supply of either test them by placing 1/2 teaspoon in a cup and add hot water. They should bubble and foam. If they don't throw them away and buy new.
How to Make This Cake
Make sure the butter, eggs, and buttermilk are all at room temperature. Room temperate means about 68 degrees F. Crack the eggs into a small bowl and measure the buttermilk into a measuring cup.
Remove the leaves from the thyme stalks by holding the stalks so the tiny leaves point upwards and then pinch the stalk between your thumb and forefinger and pull the stalk upward with your other hand. The leaves will easily come. Pinch off the leaves that are at the top of the stalk.
To bump up the flavor of this cake place the sugar in small bowl and then zest the orange onto the sugar until you have what looks like 2 teaspoons (1 large or 2 medium navel oranges). When you zest fruit directly into the sugar or other ingredients you capture the oil that makes up the flavor the fruit. Add the thyme and use your fingers to rub the zest and thyme into the sugar. The smell will be fragrant and slightly floral.
For the orange topping, you're going to need about 4 or 5 oranges depending on the size. To keep a uniform size for the upside-down oranges the middle section of the oranges is used. The juice is squeezed from the top and bottom of the orange for the orange glaze and I eat the rest.
Place 4 tablespoons of butter into a 9-inch cake pan and place it in the oven to melt. Remove the pan from the oven and brush the butter up the sides of the pan. Sprinkle the sugar evenly across the butter. Arrange the orange slices by starting in the center and creating a spiral out to the edges of the pan.
Set the pan aside, make the cake batter according to the recipe directions and gently scrape the batter on top of the oranges being careful not to disturb the oranges. Smooth the top with an offset spatula and bake the cake.
When the cake is done, allow it to cool for 10 minutes and then invert it onto a plate or serving platter. Some of the orange slices may stick to the pan. Simply remove them and place them back on the cake.
Serve the cake at room temperature with a dollop of whipped cream fraiche.
Pro Tips for Making This Cake
- This cake is made with all-purpose flour and cornmeal. Combine the buttermilk and cornmeal and allow it to sit for 15 minutes before combining it with the other ingredients. This step softens the cornmeal and allows it to mix in better with the other ingredients.
- The eggs, butter, and buttermilk should all be at room temperate before starting this recipe.
- If the oranges have really thick peels (greater than 1/4-inch) remove the peels after slicing the oranges. Peels that are too thick will make this dessert too bitter.
- Use a sharp thin blade to slice the oranges.
- Whether you're making Orange, Lemon or Pineapple Upside-Down Cake change the spices in the cake batter to complement the fruit that you're using. In my Meyer Lemon Upside Down Cake I used ginger and cardamon. In a pineapple upside-down cake consider using allspice.

- 3/4 cup (150 grams) granulated sugar
- 1/4 teaspoon kosher salt
- 4 Cara Cara oranges sliced 1/4-inch thick
- 1/3 cup (60 grams) cornmeal
- 3/4 cup buttermilk
- 1 1/4 cups (162 grams) all-purpose flour
- 1 1/2 teaspoons baking powder
- 1/4 teaspoon baking soda
- 1/2 teaspoon kosher salt
- 1 cup (200 grams) granulated sugar
- 2 teaspoons navel orange zest
- 2 teaspoons fresh thyme
- 1/2 cup (114 grams) unsalted butter room temperature
- 2 (100 grams) large eggs room temperature
- 2 tablespoons fresh-squeezed orange juice
- 1 tablespoon fresh squeezed lemon juice
- 2 tablespoons granulated sugar
- 1 tablespoon apricot jam Smucker's brand recommended
- Place the cornmeal and buttermilk in a small bowl and whisk to combine. Allow this mixture to sit for 15 minutes before adding to the other ingredients. This step softens the cornmeal.
For the Orange Topping
- Preheat the oven to 350 degrees. Cut the butter into 4 pieces, place them in the 9-inch cake pan and place the pan in the oven. Melt the butter until it just melted - 2 minutes. With a pastry brush, brush the butter up the sides of the pan. Sprinkle the sugar over the butter. Layer the orange slices on top of the sugar, overlapping the oranges in spiral pattern.
For the Cake
- Place the flour, salt, baking powder, and baking soda in a medium bowl and whisk until the ingredients are well combined, about 30 seconds.
- Place the sugar in a medium bowl. Zest the orange on top of the sugar, until you have what looks like 2 teaspoons. Add the thyme and use your fingers to rub the zest and thyme into the sugar. Place the sugar in the bowl of a stand mixer. Add the butter. Beat the butter and sugar mixture on medium speed until light and fluffy, about 3 to 4 minutes.
- Add one egg at a time, beating after each addition. Add half of the flour mixture and mix at low speed until well combined. There may be some flour on the sides of the bowl - that's okay. Add all the buttermilk-cornmeal mixture and mix on low speed until combined. Add the remaining flour and mix on low speed. Scrape the sides and bottom of the bowl and mix for another 10 seconds to ensure all the ingredients are well combined
- Gently pour the batter over the orange slices and smooth the top with an offset spatula. Bake until a cake tester comes out clean, about 45 minutes. Let the cake cool in the pan for 10 minutes. Run a knife around the edges to release the cake and invert it onto a platter or plate.
Orange Glaze (Optional)
- Make this glaze after the cake has cooled to room temperature.
- Combine the orange juice, lemon juice, and sugar in a small saucepan and bring to a boil. Reduce the heat to medium-low and allow it to simmer until it thickens. Stir in the apricot jam and then remove the pan from the heat.
- Allow the jam to cool until it is just a little warm and then brush the glaze over the top of the cake,
Serving and Storing the Cake
- Serve the cake at room temperature. You can eat the cake as soon as it is cool, but it will taste even better the next day. The cake tastes really good with a dollop of lightly sweetened whipped creme fraiche or whipped cream. Use a sharp knife to cut through the oranges and cake.
- The cake can sit a room temperature for 2 days in a covered container and in the refrigerator for 1 week.
