Citrus Upside Down Cake
This citrus upside-down cake is a one-pan vegan dessert: you press juicy mandarin slices into the base of a buttered pan, pour a soft almond-milk batter over them, and bake at 180 degrees Celsius for 30 to 35 minutes. Flip it warm and the fruit becomes a glossy, golden top. It is bright, tender, and ready in about an hour.
I was in the mood for something sweet one relaxed, free Saturday, and my first thought was to make a fast run to the supermarket. But I stopped that first impulse and decided I would make my own something sweet instead, and I landed on a citrus upside-down cake. Thinking of toppings I could use, I chose mandarins, partly because they are one of my favorite fruits, and partly because, in my country, nothing says winter better than the smell of freshly peeled citrus. I know it is a bit too early for that, but I think it is never too early to get in the holiday mood.
It was so delicious that I decided to share the recipe with you. As I am writing this, there is no more cake left, though I admit I had some helpers both in cooking and eating. I am quite proud of myself, because it is one of the best cakes I have made this year, and it is, for me at least, one of the most good-looking cakes out there. Trust me, it will be a feast to both taste and admire.
This Recipe Works If You Need
- A showstopper dessert that looks far more involved than it is, with the fruit doing all the visual work for you.
- An egg-free, dairy-optional cake you can keep fully plant-based by using almond milk and vegan butter.
- A holiday or winter table centerpiece, when the smell of freshly peeled citrus sets the mood.
- A one-bowl batter you can mix by hand, with no creaming, folding, or special equipment required.
- A way to use up a bag of mandarins before they soften, turning them into the best part of the cake.
Why You’ll Love This Recipe
- It looks impressive with no decorating skill. The mandarin slices arrange into a natural pattern, and the flip reveals a glossy, caramelized top without any frosting or piping.
- The batter comes together in one bowl. You dissolve sugar into the butter, add the wet and dry ingredients, mix until creamy, and you are done.
- It is naturally vegan. Almond milk, vegan butter, and coconut oil carry the cake, so there are no eggs and no dairy unless you choose to use them.
- The mandarins keep it moist. Their juice seeps into the crumb as it bakes, so the cake stays tender rather than dry.
- It is a four-seasons cake with a winter heart. You can bake it any time, but the citrus aroma makes it feel like a holiday.
- It rewards patience but forgives haste. The 15-minute batter rest improves the texture, yet the recipe is hard to ruin.
Ingredient Notes
Mandarins are the star here, and you need four. Choose fruit that feels heavy for its size with tight, glossy skin, which signals juiciness; light, puffy mandarins are drying out inside. Peel them, pull away as much of the white pith and stringy membrane as you can, since that part turns bitter when baked, and cut them horizontally into thick slices so they hold their round shape on top of the cake.
Flour makes up the structure, at one and a half cups. Spoon it into the measuring cup and level it off rather than scooping straight from the bag, because a packed cup adds extra flour and gives you a heavier, drier crumb.
Sugar appears twice in this cake. Six tablespoons go into the batter, and a separate sprinkle of brown sugar coats the buttered pan. The brown sugar is what melts with the coconut oil and mandarin juice to form that glossy layer on the flipped cake, so do not skip it for the base.
Almond milk is the liquid, and the recipe calls for it warm. Warming it helps the melted butter stay smooth instead of seizing into specks when the two meet. Use plain, unsweetened almond milk so the cake is not overly sweet, or swap in regular dairy milk if you are not keeping it vegan.
Vegan butter, melted, brings richness and helps dissolve the sugar. Melt it gently so it is liquid but not hot, and use a block-style vegan butter rather than a soft spread, since spreads carry more water and can throw off the batter. Regular dairy butter works in its place if vegan is not a requirement for you.
Mandarin or orange juice, a quarter cup, deepens the citrus flavor in the crumb itself. Squeeze it fresh from one of your mandarins or an orange for the brightest result; bottled juice works but tastes flatter.
Coconut oil brushes the baking tray and, together with the brown sugar, creates the non-stick caramel base that lets the cake release cleanly when you flip it. Use refined coconut oil if you do not want a coconut note; unrefined adds a faint tropical aroma.
Baking powder and baking soda work together for lift, with two teaspoons of powder and one of soda. Make sure both are fresh, because old leaveners are the most common reason an upside-down cake bakes up dense and flat. The soda also reacts with the acidic citrus juice to give the crumb its rise.
Vanilla extract and a pinch of salt round everything out. Half a teaspoon of vanilla warms the citrus, and the salt sharpens the sweetness rather than making the cake taste salty, so do not leave it out.
Tips
- Do not skip the 15-minute rest. Letting the batter sit hydrates the flour and gives the leaveners a head start, so the cake bakes up with a finer, more even crumb. While it rests, you can slice the mandarins and prep the pan.
- Sprinkle the brown sugar on the bottom and the sides. Coating the sides as well as the base means the caramel wraps the edges of the cake, so the whole top gleams after you flip it, not just the center.
- Check doneness with a toothpick. Insert it into the center near the end of the 30 to 35 minutes; it should come out mostly clean with no wet batter clinging to it. The top will also spring back lightly when pressed.
- Rest the cake 10 minutes, then flip while still warm. Too soon and it falls apart; fully cold and the caramel sets hard and sticks to the pan. Ten minutes is the sweet spot for a clean release.
- Flip with confidence. Set your serving plate over the pan, hold both together, and turn them over in one decisive motion rather than easing it slowly, which is when slices shift out of place.
Substitutions and Variations
- Swap the mandarins for oranges. Thin-skinned oranges work beautifully sliced the same way, and the cake turns into an orange upside-down version with a slightly more tart edge.
- Make it dairy instead of vegan. The card allows regular dairy milk in place of almond milk and regular dairy butter in place of vegan butter, so you can use what you have on hand.
- Adjust the sweetness. Mandarins vary in sugar from batch to batch; with very sweet fruit you can trim the batter sugar slightly, or add a touch more brown sugar to the pan for a deeper caramel with tart fruit.
- Add a warming spice. A pinch of cinnamon or cardamom in the batter leans the cake further into holiday territory without competing with the citrus.
Storage and Make Ahead
This cake is at its best the day it is baked, when the caramelized citrus top is still glossy and the crumb is freshly tender. Keep leftovers covered at room temperature for up to a day, or in the fridge for three to four days; the fruit will release a little more moisture over time, so the texture grows softer and more pudding-like, which I do not mind at all. Let chilled slices come to room temperature before serving, or warm them briefly so the top loosens again. Serve with vegan whipped cream, as the recipe suggests, for a bit of contrast against the bright fruit.
If you love this kind of fruit-forward, flipped dessert, my upside-down apple pie uses the same technique with autumn apples.

Notes
Frequently Asked Questions
It is a cake baked with sliced citrus fruit arranged on the bottom of the pan and the batter poured over the top. Once it bakes and you flip it onto a plate, the fruit ends up on top in a glossy, caramelized layer. This version uses mandarins and a soft almond-milk batter, and it is fully vegan when made with almond milk and vegan butter.
Yes. Oranges work in place of mandarins, sliced horizontally into thick rounds the same way. The recipe even calls for mandarin or orange juice in the batter, so an all-orange version is a natural swap. Expect a slightly more tart, less candy-sweet result than mandarins give.
Brush the baking tray with coconut oil and sprinkle the bottom and sides with brown sugar before adding the fruit. This forms a caramel layer that releases the cake cleanly. Then let the baked cake rest for 10 minutes before flipping; too soon and it tears, fully cold and the caramel sets hard.
Resting the batter lets the flour fully hydrate and gives the baking powder and baking soda a head start, which produces a finer, more even crumb. It is a short, hands-off step, so use the time to slice the mandarins and prep the pan.
Bake at 180 degrees Celsius for 30 to 35 minutes, then check with a toothpick inserted into the center. It should come out mostly clean with no wet batter clinging to it. The top should also spring back lightly when pressed.
Yes, it is vegan as written, using warm almond milk, melted vegan butter, and coconut oil, with no eggs. The recipe also offers regular dairy milk and dairy butter as optional swaps if you are not keeping it plant-based. Serve it with vegan whipped cream to keep the whole dessert dairy-free.
Do you think it would be good using orange slices?
Yes 🙂 It works with any citrus fruit.
Extremely easy and super delicious, I LOVED it! 🙂
