A Taste of Danish Summer: Endeavour into Flavours

There is just something about such a glass of old-fashioned Danish rhubarb cake with Danish macaroons and whipped cream, and everything. The taste of the sour rhubarb pudding, the sweet crunch of macaroons and crumble, and then the creamy and delicious whipped cream and almonds on top. Yum, Yum, Yum…!

It is a dessert we make again and again during the summer, and for that matter also in the autumn because we often have rhubarb in the freezer after the season ends. It is an easy dessert, it tastes terrific, and then you can make it well in advance.

We love to serve old-fashioned danish rhubarb cake, or “gammeldags rabarberkage” as we call it, in a glass, but if you would rather serve completely traditional in a large bowl, then, of course, you just do it instead. The recipe is exactly the same. We just think the glasses are easier, and then it also looks super nice.

Dig Deeper: Notes on the Key Ingredients

Rhubarb – You can use all kinds of rhubarb, but depending on the sweetness of the ones you use, you may need a little more sugar in the pudding. Here it is a mixture of the sweet red strawberry rhubarb and some old-fashioned rhubarb varieties that are greener in the stems.

Danish Macaroons – Here you can use pre-purchased danish macaroons or make your own. It is entirely up to you. Danish macaroons can not be bought outside Denmark to my knowledge, you can though buy them online here.

Crumble – Yes, in most places it is probably called apple cake crumble, but now it is not old-fashioned apple cake but old-fashioned rhubarb cake. But apple cake crumble can also be made yourself or bought ready-made. Here in the recipe, I make it myself, it is so easy, but you can, of course, buy it ready-made in the supermarket if you live in Denmark.

Whipped cream – Whipped cream is needed on Danish rhubarb cake. That’s just how it is.

Almonds – Almonds and rhubarb go well together. That is why we always serve almond flakes on rhubarb pudding and old-fashioned Danish rhubarb cake.

How to make Old-fashioned Danish Rhubarb cake?

Old-fashioned Danish rhubarb cake is both an easy and really delicious classic Danish dessert. The first thing to do is to prepare the various elements.

The rhubarb pudding must be made from rhubarb, vanilla, sugar, and water, and then a crumble must be made. It is made by roasting bread crumbs and sugar in melted butter on a frying pan. Last but not least, whip the cream.

When all the elements are ready and cooled down, the dessert can be assembled. First a layer of rhubarb pudding, then a layer of crumble and danish macaroons, and then rhubarb pudding again before adding whipped cream and almonds on top.

  • Stir potato starch into ½dl of water and pour it into the pudding while stirring. Add the thickener until you are satisfied with the consistency of the pudding. Remember it gets a little thicker when it cools down.
  • Take the pudding off the heat and let it cool in a bowl before putting it in the fridge. Sprinkle a little sugar on top so that it does not form a skin.


  • Melt the butter in a frying pan.
  • Put bread crumbs and sugar on the pan and fry it over medium heat until the crumble is golden, it takes about 5-10 minutes. Place the crumble to cool on a piece of baking paper.


  • Whip the cream to a light and fluffy whipped cream.
  • Serve the dessert in a serving glass or in a large bowl, the procedure is the same.
  • First, put a layer of rhubarb pudding in the bottom, and then put a layer of crumble on top. Crush the danish macaroons and spread them on top of the crumble. Now put another layer of rhubarb pudding on top, and finally whipped cream. Sprinkle with almond flakes on top and now the dessert is ready to serve.
