Fale Dunaju, or Polish apple cake

As I was growing up I used to think that Poland is the country with the richest cake tradition in the world. I had two grandmas – one Italian and one Polish – and the Polish one was definitely the best cake maker of the two. Her recipe book seemed an endless source of cake possibilities. Her daughters, my mom and my aunt, are no less talented when it comes to making cakes. When my mom started making my grandma’s recipes in Italy, everyone praised her cakes. Even something as simple as apple pie would make everyone talk about it for days. Polish apple cake was special.

Polish apple cake is indeed quite spectacular and its show factor just rises when you slice through it and take out a piece. Each slice of this cake displays a wavy pattern where the light and dark batters meet. This is what gives Polish apple cake its name, Fale Dunaju, which means “waves of the Danube” in Polish. It just takes a very simple step in the preparation of this cake to achieve this effect that always has everyone enchanted.

A stormy day on the Danube, on this slice.

First, you spread half of the batter in the baking pan. Then, you add cocoa powder to the other half of the batter and mix it well. Then it’s all about spreading the brown batter over the other layer, making sure not to mix them up. Spoon it out, little by little, and even it out with a spatula. I find it helpful to push it all the way to the edges, making sure the batter touches the edges of the pan. This usually helps “seal” the light batter underneath. Then it’s all about pressing the apple slices down. Press them so that they basically touch the bottom of the pan. When the cake bakes, the light batter will come towards the top, being weighed down where an apple piece sits. This is how you get the Danube wave effect.

There is a similar cake in the German pastry tradition and its German name (Donauwelle) means exactly the same thing. The main difference from the Polish version is that the German cake has cherries instead of apples. A layer of buttercream on the top completes the cake. Apparently, even the Polish version of this cake should feature some icing on the top. But this is not the way my grandma used to make it. Her fale Dunaju was complete with a generous sprinkle of sugar on the top, and that sugary crust has always been my favourite asset. Who needs buttercream when you have a sugar crust, after all.

Course Dessert
Cuisine Polish
Prep Time 25 minutes
Cook Time 35 minutes
Total Time 1 hour
Servings 10 portions


  • 250 g margarine (room temperature)
  • 200 g sugar
  • 5 eggs (room temperature)
  • 300 g flour
  • 2 tsp baking powder
  • 2 tbsp unsweetened cocoa powder
  • 2 apples
  • 1 tbsp coarse cane sugar


  1. Preheat the oven to 180°C. Peel and cut the apples in thin slices, then set aside. Don't worry if they turn slightly brown as they sit. This will not be a problem once the apples get cooked in the cake.

  2. Separate the egg whites from the yolks. Beat the whites until soft peaks form. Still mixing, add a little sugar - that will slightly stiffen the mixture - then set aside. 

  3. In another bowl, cream the margarine with the rest of the sugar. Add the yolks, one at a time. When done, set the mixer aside.

  4. Sift the baking powder and half of the flour into the margarine mixture and fold in by hand using a spatula or wooden spoon. Once incorporated, add the second half of the flour and fold that in. The batter gets quite hard, and that is the right texture.

  5. When all the flour has been incorporated, gently fold in the egg whites making sure not to knock too much air out of them. This step will make the batter thinner and fluffier.

  6. Pour half of the batter into a 24-cm round cake pan and spread it all over the bottom, making an even layer.

  7. Sift the cocoa powder into the rest of the batter and fold in. Spread cocoa batter  all over the other batter layer in the baking pan.

  8. Press apple slices into the batter, making sure to pierce right through so that they touch the bottom of the pan. 

  9. Sprinkle cane sugar (or any kind of coarser sugar) all over the cake top.

  10. Bake the cake at 180°C for 35 minutes or until a toothpick inserted in the middle comes out clean. Make sure to avoid piercing through an apple slice or the moisture of the fruit might make you fail the toothpick test.

The recipe that has been passed down to me features margarine. Feel free to swap it with unsalted butterif you prefer. Sure, butter tastes delicious and it surely makes the end flavour of this cake even richer. It was not always available in my grandparents’ house, though, as margarine was a much cheaper alternative. So to me this cake must be made with margarine. Whatever the fat of your choice, this cake always comes out with a wonderful fluffy texture. It takes a small workout to incorporate by hand the flour into the cake batter, but the final product is really worth the effort.

    Eva, this is such a lovely family recipe, and I love the beautiful pattern on top of the cake! I have missed your posts very much and was so happy to see that you had posted today! However, I completely understand — life can become very busy and time can fly by so quickly!

    1. Eva November 21, 2015 at 19:37

      I was feeling really sorry to be away from the blog because it had become a routine I was enjoying a lot, but I was so busy I completely lost track of time – November is almost over? ùHow did that happen?! I’ll try to get back to a little more regular blogging now!

      1. Anna November 22, 2015 at 00:32

        I completely understand — it seems the last few months have flown by very quickly! It’s wonderful to hear from you again, Eva!

  3. Rowena November 20, 2015 at 10:04

    I could stare at these cake photos for hours….WOW!

    1. Eva November 21, 2015 at 19:38

      Thanks a lot! I tried to include some other objects in the pictures, not only cake-related, and I like how they fit in the photos 🙂

  4. Karoline November 22, 2015 at 11:44

    Looks delicious! I’m definitely going to try that soon. 🙂

      Please do! It has a wonderful soft texture 🙂

    I’ve never heard of this type of cake before, but would love to try because it looks delicious! Love the chocolate and apple pairing here. Bet it smells AMAZING as it bakes 🙂

    1. Eva September 10, 2018 at 14:30

      YES! It fills the kitchen with a wonderful apple and cocoa scent. The only thing that beats that smell is the flavour of the cake when you finally get to taste it 😀

    this one won my heart totally. I just love the top. I have never tried a polish recipe before. I guess what best other than an apple cake.

    1. Eva September 14, 2018 at 19:43

      I think every place has a traditional recipe for apple cake or pie, or apple something (I’m thinking strudel). Glad I had this chance to introduce you to a Polish recipe!!

  7. Julie September 14, 2018 at 19:38

    I generally don’t think about pairing chocolate with apples, but this cake has such a striking, beautiful appearance. I love the waves!

    1. Eva September 14, 2018 at 19:42

      Once I just ditched the apples and used pears (that’s what I had). I also couldn’t care less about the wavy pattern and just went all chocolate (because chocolate and pear is heaven). It was divine! So if you think that you would like it better like this, I’d say go for pears!

  8. Dominique | Perchance to Cook September 14, 2018 at 19:52

    I love the idea to add cocoa powder to an apple cake. I’ve never tried that before but the flavor combination sounds delicious. Can’t wait to try it!

    1. Eva September 14, 2018 at 20:03

      It is quite peculiar to have cocoa powderin an apple cake recipe, I agree. I hope you enjoy!

    It certainly is a lovely recipe. Don’t you just love traditional recipes passed down in a family. I wish I would have known my Italian grandparents but they died when my parents were young. There is a decided German influence in our Italian food because of where we lived. I’d love to have a taste of your apple cake.

    1. Eva September 15, 2018 at 17:06

      I am guessing your roots are in the Trentino Alto Adige region then, if you speak of German influences in your food? Italian food is much more varied than what people tend to know. I am from one of the regions that border with France and we do share something of our food tradition with the French of the region just across the Alps. My husband is from the other side of northern Italy and his food is heavily influenced by the Balkans and by Austria! It’s amazing how rich a food heritage can be!

    I love fall just because it is apple season!! This cake looks like the perfect recipe to make with all of the apples I am going to be buying!

    1. Eva September 16, 2018 at 17:36

      Fantastic! I’m glad I helped you plan for an apple recipe now that it’s the perfect time for that kind of baking!

    This cake is gorgeous! It certainly lives up to its name. I would love to make it for a fall harvest celebration.

    1. Eva September 16, 2018 at 19:02

      I’m happy I revamped this post in time for apple season because I love sharing this recipe!

    What a beautiful cake! I really like the addition of chocolate to the top layer. This would be perfect for a fall treat.

    1. Eva September 17, 2018 at 15:01

      It really is, I make it every fall. When apples are in season and all you need is the comforting flavour of a childhood favourite… Autumn is also my favourite season, so it all pairs up so wonderfully.

  13. Kelsey September 17, 2018 at 02:58

    Wow! This is so pretty and I love how few ingredients it takes to make! That is my favorite part!

    1. Eva September 17, 2018 at 15:02

      It’s really simple! Perfect to bring to parties, it requires minimum effort (well, if you don’t count the whisking workout!) and it always pleases the crowds 😀

  14. Kitty September 17, 2018 at 05:12

    I love family recipes. I wish I had gotten more from my grandmother before she passed. Thanks for sharing!

    1. Eva September 17, 2018 at 15:03

      Having her recipes as her legacy is what makes me feel like she’s still around. She passed away earlier this year and it still feels so strange. But she lives on in her recipes, and I think it is a beautiful way to be remembered.

  15. Nicolas Hortense September 18, 2018 at 04:26

    That is one gorgeous cake!! love that ripple effect on the inside. Definitely nice to see a new cuisine (:

    1. Eva September 18, 2018 at 19:49

      I’m glad you got to see something new in my post 🙂
