Why you should make this recipe

This cake is uber-citrusy and very moist. It is perfect as is, right out of the pan and because it is so moist, it lasts for days. I think of upside down cakes as very rustic or “homey” desserts. If this sounds like your kind of sweet treat, I think you’ll like it.

  • Easy to make – This cake is easier to make than it looks.
  • Perfect for special occasions – A great addition to holiday dinners or special celebrations.
  • Versatile – Mandarins are available year round, which make them a great option for this cake.

Clementine upside down cake

This is a cake that I make almost every Christmas. It looks like it took all day, when in fact, it did not. Made with buttermilk to give it a little tang, this cake is just barely sweet. It goes really well with a cup of coffee or tea as a breakfast treat or a dessert.

Ingredients

This simple clementine cake recipe is made with common ingredients that you likely already have in your pantry.

Ingredients for clementine upside down cake on white background.
  • All-purpose flour – Weighing your flour is the most accurate way to measure. I highly recommend using a scale to measure flour. 
  • Butter – Use unsalted butter so you can control the amount of salt in your baked goods.
  • Clementines – Clementines are a type of mandarin orange. They are a hybrid of a sweet orange + a mandarin.
    • Substitution: Mandarin oranges, like Cuties, are the perfect swap.
  • Vanilla – Vanilla extract gives baked goods that familiar flavor we all love.
  • Sugar  – Granulated white sugar provides just a touch of sweetness. The glass canisters make it easy to see what you have.
  • Buttermilk – Buttermilk gives the upside down cake moisture and tang.
  • Eggs – Eggs provide moisture and structure to the batter.
  • Salt – All baked goods need salt. I use Diamond Crystal in all of my recipes.
  • Baking powder – Baking powder gives the cake a bit of lift.
  • Baking soda – Baking soda reacts with the acid in the buttermilk to give the cake a fluffy interior.

This is the scale that I own and use daily. It is easy to use, plus it measures in pounds, ounces and grams.

Measuring ingredients by weight, ESPECIALLY in baking, is much more accurate than cup measurement.

Step by step photos showing how to make a clementine upside down cake.
  1. Prep – Preheat oven to 350°F // 180°C // Gas mark 4. Mix wet ingredients in one bowl and whisk dry ingredients in a separate bowl.
  2. Slice – Boil the thin slices of clementine for a few minutes to soften them. Then arrange the slices in a circular pattern in the cake pan.
  3. Scoop – Using a large cookie scoop or spoon, gently scoop the batter on top of the sliced clementines.
  4. Bake – Bake for 35 minutes, or until a toothpick inserted in the center of the cake comes out with a few crumbs attached. Let it cool slightly before flipping over and removing cake from pan.

Clementine upside down cake FAQ’s

What kind of pan do I need to bake this clementine cake?

I bake this cake in a standard 9×2 cake pan, but I suggest placing the pan on a baking sheet, just in case it bubbles over. If you own a 9×3 cake pan, use it.

Can I make it ahead?

Yes. This cake is perfect for making ahead of time. You can make it up to 2 days before.

How long will it stay fresh?

You can store this cake in an airtight container at cool room temperature for up to a week.

Variations and substitutions

  • Add a little spice – Add in a 1/2 teaspoon of ground cardamom for a little extra spice.
  • Substitute – If you can’t find clementines, use mandarin oranges. Clementines are in season during the winter months, but mandarin oranges are available year-round.

Serving suggestions

I love this cake as it is, with a cup of coffee or tea. You can dust the top with powdered sugar, if you like, for a little decoration.

If you want a sauce to pour over the cake, try this crème anglaise from my bread pudding recipe.

Helpful tools and equipment

  • Possibly one of the greatest things ever invented – 9 inch parchment paper rounds. These pre-cut pieces of parchment paper go directly on the bottom of your pan creating a layer between the pan and your cake making it easy to remove with no sticking.
  • Cake pans – If you have a 9 x 3 cake pan, this is the time to use it. Those high sides will give your cake nice, straight sides and you won’t have to obsessively look through the oven glass to make sure it isn’t spilling over.
  • Small offset spatula – When you scoop the cake batter on top of the clementines, you’ll need to smooth the top before putting the cake in the oven. This offset spatula is small enough to allow you to get in the pan easily without hitting the side of the cake pan.
  • You’ll also need the basics like mixing bowls, measuring cups and spoons and a hand mixer.

  • 12 tbsp. unsalted butter, room temp // 170g

  • 1 tsp. kosher salt
  • 2 large eggs
  • 1/2 cup + 2 tbsp. buttermilk

Instructions

  1. Preheat oven to 350°F / 180°C / Gas mark 4.
  2. Thinly slice 5 of the clementines, then set aside. Zest and juice remaining 3 clementines. Set aside.
  3. Bring a medium pot of water to a boil and add clementine slices. Boil 3 minutes, then drain and arrange slices on a layer of paper towel to dry before proceeding.
  4. If using, place a parchment paper round in the bottom of your cake pan. Place 4 tbsp. of butter in a 9 x 2 cake pan and place in the oven to melt.
  5. When butter has melted, add 1/2 cup sugar and 2 tbsp. clementine juice. Whisk to combine.
  6. Arrange clementine slices in pan on top of sugar mixture, starting in the center and working out from the middle. Make sure to overlap slices to secure them in place. Set pan aside.

  10. Gently scoop batter on top of clementine slices and smooth the top with an offset spatula.
  11. Bake until cake is golden and puffed, and a cake tester (toothpick) comes out with a few crumbs attached, 30 to 35 minutes. Transfer to a wire rack to cool in the pan for 10 - 15 minutes.
  12. Gently run a knife around the edge of the pan to loosen the cake, then invert onto cooling rack to cool completely. Let cool before slicing.

Please note - you'll need 8 clementines TOTAL for the recipe.
To serve later: If you are not serving the same day, wrap cake very well in plastic wrap while still warm and place in freezer. Thaw at room temp (not in refrigerator) for a few hours before serving.

  1. This post made me cry for so many reasons. I love reading your posts, you are honest and poetic all at once. And what a story! You just ooze courageousness and I have admired you for that since we met. But I guess we are all scared of the unknown. This post means more to me than you can know, and it is advice I so needed right now to start off the new year with. And the cake is absolutely stunning. I am so happy and so lucky to have met you this year and count you as a good friend. xo

    1. Jamie, you have no idea what your words mean to me. To think that you enjoy reading what I write fills me with such happiness. Your writing is so beautiful and graceful, like a well choreographed ballet, and my writing aspires to be your first draft full of red ink, eraser marks and scratched out lines.
      I am so lucky to call you friend. <3

  2. Moving is so hard and takes such courage. It’s stepping off the deep end and trusting yourself enough to know that you are capable, more than capable even, and that it’s all going to turn out okay in the end. I’m glad you chose to share this particular post with our new group first, Cheryl. I knew you were someone special because of how Jenni feels about you. Now you’ve shown me that in your own words.

    P.S. That cake is something special too. Just beautiful!

    1. I’m sure it would be fine, but honestly I’ve never tried it so I can’t say “absolutely!”
      Give it a shot and let me know how it turned out! 🙂
