Indonesia experienced a colonial history under the Dutch for a long time. The Dutch colonial period in Indonesia made so much impact on Indonesian people’s lives and cuisine. When the Dutch arrived, they brought their cooking and baking methods. Many Indonesian recipes trace their roots to the Dutch colonial era, and one of them is Klappertaart.

What is Klappertaart?

Klappertaart literally means “coconut cake” or “coconut tart” in Dutch. It is a Dutch-influenced Indonesian cake originating from Manado, the capital city of the province of North Sulawesi.

It is a cake with coconut as the main ingredient. The base is soft custard with young coconut meat slices, raisins, and nuts mixed in the cake. The top is finished with a thin layer of sweet and fluffy meringue. The recipe is greatly influenced by the European style of cooking. 

There are several ways to cook Klappertaart. The entire thing can be steamed or baked until fully cooked. There is also the no-bake version.

Manado’s Christmas Cake

Klappertaart becomes popular due to its delicious taste. As time went by, the Christians in Manado created a tradition to bake this cake for Christmas and to celebrate other festive moments.

Ingredients You Need

Custard

  • Coconut water – Coconut water is the clear fluid found inside the center of a young, green coconut.
  • Milk – To add richness.
  • All-purpose flour – To thicken the custard.
  • Cornstarch – To thicken the custard.
  • Granulated sugar – To sweeten.
  • Salt – To balance the sweetness.
  • Unsalted butter – Adding richness.
  • Egg yolks – The main thickener in custard and add richness to the cake.
  • Vanilla extract – To enhance the flavor.
  • Rhum – Rhum is completely optional, but it is recommended for deeper flavor.

Add-ins and toppings

  • Young coconut meat slices – Use the coconut meat inside the center of young, green coconuts, which is still soft and scoopable. The coconut meat will be too hard if you use mature coconut instead of green coconut.
  • Raisins – Soak raisins in warm water before using to soften them.
  • Kenari nuts – Kenari nut or also known as pili nut is a native nut from Indonesia with a tear shape similar to the almond. You can substitute kenari nuts with sliced almonds. Make sure to toast the nuts before adding it to the custard base.

Meringue

  • Egg whites – Bring the egg whites to room temperature for more volume and help the sugar to dissolve easily.
  • Granulated sugar – Add granulated sugar little by little as this will help it incorporate.
  • Salt – To taste.
  • Ground cinnamon – To spice the dessert.

How to Make

  1. Cut open two young, green coconuts. Drain the coconut water in a big bowl. Use a spoon to scoop the coconut meat inside. Set aside.
  2. In a medium saucepan, add all-purpose flour, cornstarch, sugar, salt, coconut water, and milk. Cook on low heat while whisking constantly until the mixture thickens and boils. Remove from the heat.
