Every summer, our neighbor gives us bags of organic plums when their plum trees fruit. One of the best ways to use up those plums is to turn them into a Plum Cake (すもものケーキ). My family looks forward to this cake, especially when plums and other stone fruits are in season.

I found this plum cake recipe online (written in Japanese) several years ago when I was looking for ideas to make the most of the abundant plums I had. This original recipe came from the baker’s British mother-in-law and I adapted the recipe to make it in my 9-inch cake pan with a few additional ingredients.

Why You Should Make This Plum Cake

  • Incredibly easy! Just mix all the ingredients and bake!
  • The recipe is easy to memorize (in metrics) and highly adaptable. See the next section.
  • The cake is so delicious and outstanding!
  • You can use various fruits (blueberries and peaches) to make the cake year-round.

This cake is a delicious way to end the day. Yet, it’s also gorgeous enough to grace any special occasion or a last-minute brunch party. Serve it plain, or topped with vanilla ice cream or crème fraîche.

The Basic Cake Batter Recipe That’s Easy to Remember

As I mentioned earlier, this cake batter is so easy to remember. I usually make dessert recipes using a metric measurement (with a kitchen scale). *The cup measurement is written on the recipe card. I find it a little harder to memorize than this metric recipe.

For a 7-8 inch (18-20 cm) round pan

  • 100 g unsalted butter
  • 100 g sugar
  • 100 g eggs (2 large eggs)
  • 100 g all-purpose flour
  • 1 tsp baking powder
  • pinch kosher salt
  • 1 tsp almond or vanilla extract

* You can also use a 6-inch (15 cm) square pan.

For a 9-10 inch (23-25 cm) round pan

  • 150 g unsalted butter
  • 150 g sugar
  • 150 g eggs (3 large eggs)
  • 150 g all-purpose flour
  • 1 1/2 tsp baking powder
  • 1/2 tsp kosher salt
  • 1 1/2 tsp almond or vanilla extract

* You can also use an 8-inch (20 cm) square pan.

How to Make the Best Plum Cake

  1. Before you start: Preheat the oven to 350ºF (ºC) and bring the butter and eggs to room temperature.
  2. Make the batter: Cream the butter and sugar in a bowl. Add eggs one at a time and add almond/vanilla extract. Add dry ingredients and mix to combine.
  3. Prepare the cake pan: Spread the cake batter into a spring-form pan. Place the plum halves skin side up on top of the batter. Sprinkle ground cinnamon and sugar (crystal or turbinado sugar).
  4. Bake the cake: Bake in a preheated 350ºF oven for 35-45 minutes.
  5. Enjoy! Let cool slightly and remove the cake pan. Enjoy the cake with a cup of tea (Hot Cinnamon Spice is my favorite to go with this cake).

Cake Batter Variations

Over the years, I’ve made different variations of the basic cake batter recipe above. I keep the core ingredients but change things up slightly based on the fruits.

  • Lemon zest
  • Almond slices
  • Ground cardamom (you can also use ground cinnamon and nutmeg combo)
  • Vanilla extract (I use the almond extract as basic)
  • Crystallized ginger

Baking Tips

  • Pan options: I use a standard 9-inch springform pan and the cake bakes beautifully. If you don’t own one, you can line a regular 9-inch cake pan with parchment paper and the cake should come out well. If you want to bake the cake in an 8-inch square cake pan, please check the baking time as it may require extra time to bake or finish earlier than the specified time.
  • Flour options: I’ve tried this recipe with both all-purpose flour and cake flour, and they come out equally well. I haven’t tried combining it with the almond meal but I think that will work too. I assume gluten-free flour should work, too.
  • Almond or vanilla extract: My family loves almond extract in this recipe (it’s our secret ingredient in making waffles!), but feel free to use vanilla if that’s what you have on hand.
  • Optional ground cinnamon: I love sprinkling ground cinnamon for an extra bit of flavor. Warm spices like cinnamon, nutmeg, and cardamom complement the fruit very well.
  • Sparkling sugar crystal or turbinado sugar: I highly recommend sprinkling crystal or turbinado sugar on top of the cake. It gives a little sparkle on top of the cake as well as a light crackly crust. If you don’t have this type of sugar, you can simply use regular granulated sugar. If your plums are slightly sour, I find the sugar topping necessary and may want to increase the amount a tiny bit.

How to Substitute Plums with Other Fruits

If you are not a fan of plums, you can definitely substitute them with other fruits. In general, I think you can use pretty much any kind of fruit.

  • Peaches
  • Blueberries
  • Figs
  • Apricots

Peach Cake

Slice 2 fresh peaches into 8-12 wedges, coat them with lemon juice to prevent them from turning brown, and fan them out on the cake batter.

Blueberry Cake

Combine 2 cups (300 g) of fresh blueberries with 1 tsp flour and lemon juice in a bowl. Spoon the berry mixture over the batter. If you use frozen blueberries, use them frozen. The flour coating is to prevent the blueberries from sinking to the bottom of the cake.

Fig Cake

Slice 10-14 fresh figs vertically in half and place them flesh side up.

Apricot Cake

Slice 10-12 fresh apricots vertically in half or quarters and place them skin side up.

Plum Cake Storage

The cake will keep well covered (I usually use a cake stand with a dome lid) at room temperature for 2 days or in the refrigerator for up to 5 days. I actually prefer to make this cake a day in advance as it tastes better the next day.

You can also freeze the leftover cake for up to 3 months.

Instructions 

  • Before You Start: I highly encourage you to weigh your ingredients using a kitchen scale for this recipe. Click on the “Metric” button at the top of the recipe to convert the ingredient measurements to metric. If you‘re using a cup measurement, please follow the “fluff and sprinkle“ method: Fluff your flour with a spoon, sprinkle the flour into your measuring cup, and level it off. Otherwise, you may scoop more flour than you need.
  • Gather all the ingredients. For a smaller pan, see the measurement in the blog post. Preheat the oven to 350°F (180ºC) and set the oven rack in the middle position. 

  • Crack 3 large eggs (50 g each w/o shell) in a small bowl (to avoid accidentally adding a broken egg shell into the batter). In another medium bowl, whisk together 1¼ cups all-purpose flour (plain flour), 1½ tsp baking powder, and 1 tsp Diamond Crystal kosher salt.

  • Slice 6 plums in half by cutting the fruit around the pit. Hold the fruit and twist it to open.

  • Remove the pits from the halves.

  • Add 11 Tbsp unsalted butter to the bowl of an electric mixer fitted with the paddle attachment or beaters. Grease a 9-inch springform pan (both the sides and bottom) with the residual butter left on the wrapper.

  • You can line the bottom of the cake pan with a parchment paper circle (optional). This will make it easier to remove the cake from the pan.

  • Add ¾ cup sugar to the mixer bowl. Cream the butter and sugar until pale and fluffy, about 3 minutes.

  • Add the eggs, one at a time, and beat on low speed until well combined.

  • Using the silicone spatula, scrape down the sides of the bowl and add 1½ tsp almond extract.

  • Gradually add the flour mixture and beat on low speed until smooth and combined.

  • Scrape down the sides of the bowl with the spatula.

  • Transfer the batter to the prepared pan and smooth the top with the spatula.

  • Arrange the plums on top, skin side up in a circular pattern, to mostly cover the batter.

  • Sprinkle ¼ tsp ground cinnamon and 1½ tsp white sparkling sugar over the plums.

  • Bake for 35 to 45 minutes (larger fruit needs a longer bake time), until the cake is golden on top and a toothpick inserted into the center comes out clean.

  • Place the cake on a wire rack to cool. Run a butter knife along the outer edge of the cake to loosen it from the pan. Then, release and remove the sides of your springform pan, leaving the base in place.

To Store

  • Store the leftover cake, covered, at room temperature for 2 days or in the refrigerator for up to 5 days. Or, freeze the leftover cake for up to 3 months. Make sure to wrap the completely cooled cake with aluminum foil or plastic wrap, and then place it in a freezer bag. Thaw overnight on the countertop before serving.
