This clementine cake gets its flavor from citrus fruit, whether clementines, satsuma oranges, or tangerines. The cake itself is made from simple everyday ingredients including flour, semolina, butter, and eggs, then it’s topped with candied clementine slices.
This clementine cake may look like an upside-down cake and taste like an upside-down cake but it couldn’t be more right-side-up, with no scary moment of reckoning—or rather, wrecking—that requires you to scarily turn out the rich, buttery cake and its sticky sweet topping from the pan while preventing it from crumbling or cracking. Incidentally, this clementine cake was originally called a satsuma cake, which sounds sorta exotic but “satsuma” simply refers to all those cute little orbs of citrus that are ubiquitous at grocery stores each winter, including clementines, tangerines, even smallish navel oranges. Use whichever you fancy or can get your hands on. Any citrus with few or no seeds and thin peels that are easy to slip off* works spectacularly well atop this cake.

How To Select The Right Citrus For This Recipe
The most critical attribute of whatever citrus that you select for this recipe—whether satsumas, tangerines, clementines, or smallish navel oranges—isn’t the tartness of the segments so much as the thickness of the peel, which remains on the citrus to keep the lovely circles of segments intact and to impart a slight bitterness to the stunningly sweet glaze. Fear not, the rinds soften sufficiently to be fork-friendly and turn sweet enough to be palate-pleasing, but only if you use thin-skinned citrus. Thicker-skinned citrus such as regular oranges just can’t be coaxed to play nicely in the time allowed, and simmering them a little longer until they do turn tender brings bitter consequences, both in terms of taste and the inescapable fact that the citrus segments tend to sag and fall apart.
That said, if you can only find thick-skinned citrus, we have a fix for you. One of our veteran recipe testers, Helen Doberstein, was so taken by this simple and stunning recipe—yet vexed by the thick peels she was finding in grocery stores—that she kept tinkering until she had an aha! moment. She microwaved thicker citrus slices prior to simmering them. (Brilliant, right?) You’ll find all the essentials of her trusty trick explained in the recipe below.
- Quick Glance
- 30 M
- 1 H, 30 M
- Serves 8 to 10
Special Equipment: 9- or 10-inch springform pan
- For the glazed citrus
- 6 thin-skinned satsumas, clementines, tangerines, blood oranges, or small navel oranges, preferably organic
- Juice of 1/2 lemon
- 1 cup granulated sugar
- 1/4 teaspoon kosher salt
- For the clementine cake
- 1 stick unsalted butter (4 oz), at room temperature, plus more for the pan
- 3/4 cup granulated sugar
- 2 large eggs, at room temperature
- 1/3 cup semolina flour (or substitute all-purpose flour)
- 2/3 cup all-purpose flour
- 1 teaspoon baking powder
- 1/4 teaspoon salt
- Make the glazed citrus
- 1. Finely grate the zest of one of the citrus fruits and reserve the zest for the cake batter. Cut the citrus fruit in half, juice it, and strain the juice; you should have 1/3 cup juice. (There’s a slight chance you may need a second citrus to yield sufficient juice.)
- 2. Slice the remaining citrus fruits into very thin rounds—not paper thin, mind you, but no more than 1/4 inch thick. Remove and discard any seeds. [Editor’s Note: If using thicker-skinned citrus such as tangerines, blood oranges, or navel oranges, slice the citrus 1/4 inch thick, place the slices on a plate, and microwave on high for 2 minutes for tangerines or blood oranges, 3 minutes for navel oranges. This helps ensure the thick peel softens without turning the citrus segments soggy.]
- 3. Combine the orange juice, lemon juice, sugar, salt, and orange slices in a medium nonreactive saucepan over low heat and bring to a slow simmer. Cook for 6 to 7 minutes, until the peels are tender and the centers of the orange slices are starting to become tender and translucent but are not falling apart. If the peels aren’t yet tender enough to cut with a fork, keep simmering until they are. Using a slotted spoon, carefully transfer the orange slices to a plate. Continue to simmer the syrup until it has reduced to 1/2 cup, anywhere from 5 minutes to 15 minutes, depending on how long you simmered the orange slices and the size of your pan.

- 4. Preheat the oven to 375°F (190°C). Butter a 9- or 10-inch springform cake pan.
- 5. Toss the butter and sugar in the bowl of an electric mixer fitted with the paddle attachment and beat on medium speed until fluffy. With the mixer still running, add an egg and mix until it’s completely and indisputably incorporated before adding the second egg. When the second egg is similarly incorporated, sprinkle the grated orange zest reserved from the glaze recipe over the batter and mix until combined.
- 6. In a bowl, sift together the semolina flour, all-purpose flour, baking powder, and salt. Gently mix the flour mixture into the batter, a little at a time, and mix just until everything is incorporated and no white streaks of flour remain. Pour the batter into the buttered cake pan and smooth the surface. Arrange the glazed oranges on the batter in a single layer, allowing any excess glaze to drip from the oranges back into the pan before draping them on the cake. Reserve the remaining glaze in the pan. (You may also end up with some extra citrus slices, which is intentional, as we want you to have plenty despite the fact that some of the slices may fall apart during simmering. We like to nibble the glazed citrus as is or spoon it over yogurt.)
- 7. Bake the cake for 15 minutes. Reduce the oven temperature to 350°F (177°C) and bake the cake for 35 to 40 minutes more, for a total of 50 to 55 minutes, until the cake is an even golden brown and a toothpick inserted in the center comes out clean. Let the cake cool in the pan on a wire rack until warm, not hot. Then, using a wooden skewer, poke holes all over the surface of the cake. Brush the remaining glaze over the top using a pastry brush. Allow the cake to cool to room temperature on a wire rack before removing it from the pan or simply slice and serve the cake straight from the pan.
