Preheat oven to 180C. Line cake pan, at least 5 cm deep banana leaf with the shiny side facing up.
Combine tapioca with coconut milk, sugar, salt, butter and egg yolks in a heavy-bottomed pan.
Cook over low heat and keep stirring until it turns into a custardy mixture.
Scrape batter into lined pan. Bake on the oven’s lowest shelf for 40 to 45 minutes. Then, scatter cold butter bits over the kueh, and move pan to a high shelf in the upper third of the oven.
Bake for 10 to 15 minutes more, until bengka is well browned
Let kueh cool to at least room temperture before unmoulding. Slice with a serrated knife to serve.
