There are very simple ingredients used in this recipe:

  • Plums – fresh ripe, juicy plums
  • Eggs – fresh, organic if possible
  • Flour – all purpose will do
  • Sugar – plain sugar for sweetness
  • Cinnamon – ground cinnamon for flavor
  • Vegetable oil – needed for elasticity
  • Baking powder – raising agent
  • Vanilla extract – or almond, rum, any favorites


🍰 How To Make This Upside Down Plum Cake

This plum cake is so simple and easy to make. Just follow the steps below:

1. Make the caramel

Prepare a 8 x12 inches rectangle baking cake pan, spray it with oil and line it with parchment paper. Spray the parchment paper also.

Rinse the plums and let them dry. Make a dry caramel (Nila explains it great here) melting 5 tbsp of sugar in a  non-stick sauce pan.

Pour it gently (with care!) into the cake form and make sure it coats all the pan’s bottom.

Cut the plums in halves and remove their pits.

Place them over the caramel with the cut down. Sprinkle with lots of ground cinnamon.

Preheat the oven at 340 degrees (medium).

2. Make the batter

Separate the eggs. Place the egg whites in a large bawl and add a pinch of salt.

Start beating with a mixer until firm peaks are forming. Add in about half of the sugar and mix until it forms a meringue.

In another bawl put together the egg yolks, the remaining sugar, the oil and vanilla extract.

Mix them until the sugar dissolves and the mixture gets a silky appearance and doubles in volume. Now we’re going to add this mixture to the meringue, in 2-3 batches.

We are going to use ONLY a rubber spatula and gentle folding moves from now on.

Gently incorporate with slow moves all the yellow mixture. Next, add the sifted flour and the baking powder in the same way, mixing it slowly with folding moves so all the air stays in the batter.

Stop as soon as the flour is incorporated, don’t over mix it.

Pour the batter over the plums and evenly smooth the surface with your spatula.

3. Bake the plum cake

Bake the upside down plum cake for 30 minutes, or until a toothpick comes out clean. Take the cake out of the oven and let it rest for about 10 minutes.

Run a knife around edges to ensure it’s loosened from the baking pan. Using a quick and secure flipping move transfer the cake onto your desired platter. Remove the pan and the parchment paper and let it cool completely.

🍏 Variation: Upside Down Apple Cake

And because it was so easy, I made one with apples too, a few days later.

This cake is so versatile, you can use almost any fresh fruits at hand. I had a few apples laying around and I was asked to do something with them.

So, I decided to variate this recipe and add a little something extra.

I used 2 sliced apples instead of plums. When all the flour was incorporated, I transferred 1/3 of the batter in another bawl and added 2 tbsp of cocoa.

I poured this batter over the apples and caramel, then the white batter over it.

I finely sliced a 3rd apple and pressed those slices it into the batter so I have some pieces of fruits into the cake.

You can see the result is below: more deliciousness for me to indulge!
