Upside-Down Citrus Cake
Citrus treats have a way of instantly brightening my mood, especially in the middle of winter when everything feels a little heavier and slower. Today it snowed here in Connecticut, and while winter can sometimes feel endless, days like this remind me why I actually love it. The trees look softer under a blanket of snow, everything feels quieter, and time seems to slow down just a bit. It’s the kind of day that makes you want to bake something simple, comforting, and cozy.
That’s where this Upside-Down Citrus Cake comes in. It’s bright, fragrant, and full of fresh citrus flavor—exactly the kind of dessert that feels like sunshine when it’s cold outside. Baking with citrus in winter feels grounding and uplifting at the same time. The colors alone are enough to make the kitchen feel warmer, and the smell of oranges baking in sugar is genuinely one of my favorite winter aromas.
One of the things I love most about upside-down cakes is just how easy they are. They look impressive, but they’re honestly one of the least fussy cakes you can make. All you really do is arrange fruit slices on the bottom of the pan, pour a simple cake batter on top, and let the oven do the rest. No frosting, no decorating, nothing overly fancy. Once it’s baked and flipped, the cake is finished—beautiful fruit on top and a soft, tender crumb underneath.
This version uses a mix of raspberry oranges, navel orange, and cara cara orange, which gives the top of the cake a really gorgeous mix of colors and flavors. The citrus slices soften as they bake, soaking into a lightly sweet sugar syrup that turns jammy and glossy once the cake is inverted. Underneath is a simple vanilla cake made extra moist with yogurt, letting the citrus really shine.
This is the kind of cake I love making on a snowy afternoon—something that feels special but doesn’t require a lot of effort. It’s perfect with a cup of coffee while watching the snow fall, just as good served slightly warm as it is the next day, and proof that winter baking doesn’t have to be heavy to be comforting.
Ingredients
Citrus Topping
- 2 raspberry oranges, sliced ½-inch thick
- 1 navel orange, sliced ½-inch thick
- 1 cara cara orange, sliced ½-inch thick
- ⅓ cup granulated sugar (67 g)
- ¼ cup water (60 g)
Cake Batter
- ½ cup unsalted butter, room temperature (113 g)
- ⅓ cup granulated sugar (67 g)
- ⅓ cup light brown sugar, packed (73 g)
- 2 large eggs, room temperature (about 100 g without shells)
- 3–4 tablespoons freshly squeezed orange juice (45–60 g)
- Zest of 1 whole lemon
- 2 tablespoons vanilla extract (26 g)
- 1½ cups plus 1 tablespoon all-purpose flour (190 g)
- 1 teaspoon baking powder (4 g)
- ¼ teaspoon baking soda (1 g)
- ½ teaspoon salt (3 g)
- ⅔ cup plain yogurt (150 g)
Instructions
- Prep the pan and oven
Preheat your oven to 350°F. Line a 9-inch round cake pan with parchment paper, making sure it covers both the bottom and the sides. Spray generously with nonstick spray and set aside. - Prepare the citrus slices
With the peel still on, use a sharp knife to slice the oranges into ½-inch-thick rounds. Once sliced, carefully remove the peel from each slice by cutting away the outer ring. Doing it this way helps keep the citrus slices intact so they don’t fall apart. - Make the sugar syrup
In a microwave-safe bowl, combine the granulated sugar and water. Microwave for 45–50 seconds, or until the sugar is completely dissolved. - Assemble the citrus layer
Pour half of the sugar syrup into the bottom of the prepared cake pan. Arrange the citrus slices evenly over the syrup. Once arranged, pour the remaining sugar syrup evenly over the citrus slices. Set aside. - Make the cake batter
In a large bowl, beat the butter and sugars together until light and fluffy. Add the eggs, orange juice, lemon zest, and vanilla extract, mixing until fully combined. - Combine dry ingredients
In a separate bowl, whisk together the flour, baking powder, baking soda, and salt. - Finish the batter
Slowly alternate folding the dry ingredients and the yogurt into the wet ingredients, mixing just until combined. The batter will be thick. - Bake
Pour the batter evenly over the prepared citrus slices, spreading it gently to the edges. Bake for 35 minutes, or until the cake is set and baked through. - Cool and invert
Allow the cake to cool completely in the pan. Once fully cooled, carefully invert onto a serving plate or cake stand. Peel away the parchment before slicing.
