Lapis Surabaya is one of Indonesia’s most iconic butter cakes, featuring two golden sponge layers and a chocolate layer, lightly sandwiched with strawberry jam. Made with 30–35 egg yolks and premium butter, it has a rich flavour and an irresistibly soft, melt-in-your-mouth texture. Believed to have been influenced by Dutch colonial baking, it has become a beloved Indonesian celebration cake.

Steps

45 minutes

1

Beat the egg yolk, sugar and vanilla paste until thick, pale and fluffy. Set aside.
2

In a separate bowl, beat butter, margarine and condensed milk until light, pale and creamy.
3

To make chocolate paste, in the separate bowl mix cocoa powder, hot water and chocolate paste together and set aside.
4

4. Gently fold the whipped egg yolk mixture into the butter mixture using a spatula until thoroughly combined. Take your time with this step, as both mixtures are similar in colour. Make sure there are no pockets of unmixed butter.
5

Sift in flour, cornflour and milk powder and fold gently until no dry ingredients remain.
6

6. Divide the batter into three equal portions, approximately 420 g each. Stir the chocolate mixture into one portion, leaving the other two portions plain.
7

Pour each batter into a 24 cm square baking pan lined with baking paper.
8

Bake at 180ºC for about 25 minutes or until cooked through.
9

9. Allow the cakes to cool completely. Spread strawberry jam over one yellow layer, place the chocolate layer on top, then spread another layer of strawberry jam over the chocolate layer. Finish with the remaining yellow layer.
10

Cut the cake into 12 equal sizes and enjoy

Tips

* Beat the butter until it becomes very light and fluffy. This helps create a soft, tender cake.

* Beat the egg yolks until they reach the ribbon stage—they should fall slowly from the whisk and leave a visible trail.

* Fold the egg mixture and butter mixture together thoroughly. Since they are similar in colour, it’s easy to miss unmixed butter. If not fully incorporated, the baked cake may develop a dense, rubbery layer caused by separated butter.
