Let’s dive into the story, tips, and pure joy behind this delightful cake!


A Slice of History

German Plum Cake has been a staple in homes across Germany for centuries, especially during late summer and early fall when Zwetschgen (small, dark purple plums) are in season. These plums, often called Italian prune plums, are preferred for their firm texture and tangy-sweet flavor, which holds up beautifully during baking. Unlike larger, juicier plums, Zwetschgen won’t make your cake soggy—just perfectly luscious.

The recipe itself likely originated in Bavaria or Saxony, regions known for their love of baking with fresh, seasonal fruits. Traditionally served in the afternoon with coffee (a cultural ritual called Kaffee und Kuchen), this cake quickly became a favorite for its simplicity and versatility. The addition of streusel—a crumbly, buttery topping—was the crowning touch that elevated the dessert to legendary status.


Why You’ll Love This Cake

This cake isn’t just delicious—it’s also forgiving and incredibly versatile. The buttery streusel provides a satisfying crunch, while the plums offer a juicy tang that cuts through the sweetness. It’s a dessert that feels fancy but is actually quite simple to make. Whether you’re baking for a crowd or just treating yourself, Oma’s German Plum Cake is a winner every time.


Tips for Making the Perfect German Plum Cake

  • Choosing the Right Plums: If you can find authentic Zwetschgen, use them! If not, Italian prune plums are the next best thing. In a pinch, you can use regular plums, but try to pick firm ones that aren’t overly ripe.
  • The Streusel Game: The streusel is the star of this cake. Use cold butter, and don’t overmix—it should have a crumbly texture. If you want to jazz it up, add a pinch of cinnamon or a handful of chopped almonds.
  • Layering the Plums: Arrange the plums in overlapping rows for even coverage. This not only ensures every bite has fruit but also creates a stunning visual.
  • Baking Tip: Bake the cake until the streusel is golden brown, and you see bubbling juices from the plums peeking through. That’s your sign it’s ready to come out of the oven!

Fun Toppings and Pairings

While the cake is divine on its own, you can take it to the next level with a few toppings:

  • Whipped Cream: Light and airy, this classic topping balances the tartness of the plums.
  • Caramel Drizzle: A decadent option for those with a sweet tooth.
  • Vanilla Ice Cream: Serve a warm slice with a scoop of vanilla for a dessert that’s downright dreamy.
  • Powdered Sugar: For a simple and elegant finish, dust a light layer over the cake before serving.

Storage Tips

  • Room Temperature: Keep the cake in an airtight container at room temperature for up to two days.
  • Refrigeration: For longer storage, refrigerate the cake for up to five days. Bring it to room temperature before serving, or warm it slightly in the oven for that fresh-baked feel.
  • Freezing: Yes, you can freeze this cake! Wrap individual slices tightly in plastic wrap and place them in a freezer-safe bag. When you’re ready to enjoy, let them thaw at room temperature or reheat gently in the oven.

📢 Fun Facts About German Plum Cake

  • Zwetschgenkuchen is so popular in Germany that it often makes an appearance at village festivals and fairs.
  • In some regions, people sprinkle the cake with slivered almonds or use a quark-based dough instead of yeast or butter dough.
  • The word “Zwetschge” specifically refers to the type of plum used in this cake, while “Pflaume” is the general German word for plums.

Diabetic Version

For those looking to enjoy the classic Swabian Plum Cake without the sugar rush, this diabetic-friendly version is a delightful alternative. By substituting traditional sugar with a diabetic-friendly sweetener, you can savor the same rich flavors and comforting texture while keeping your blood sugar levels in check.

Substitution to original recipe below:

Cake:
  • Instead of 2/3 cups of sugar –> use 1/2 to 1 teaspoon of powdered stevia depending on how sweet you want it.
  • Replace 1/2 of the regular flour with almond flour, blending the rest with other gluten free flours such as tapioca or coconut flour. 
  • Instead of 1 tsp of baking powder use 2.
Topping:
  • Use 1 tsp of powdered stevia instead of 3/4 cup sugar. 
  • Instead of regular flour use coconut or tapioca flour. I would not recommend almond flour, because it will make the streusel dense.

You can get stevia in many grocery stores or on Amazon. Click on the picture or HERE to find it on Amazon.
