Kek Batik (Malaysian Tiffin)

Melt the butter in a saucepan over low heat. Whisk in the Milo chocolate powder, cocoa powder, and condensed milk.

Mix in the eggs and water. Cook, stirring, until thickened.

Remove from the heat, and stir in the biscuit pieces and cereal flakes so everything is well coated with the chocolate mixture.

Transfer the mixture into a mold (e.g. cake pan, aluminum tin, tupperware) that has been lined with parchment or plastic.

Tap the mold a few times on a hard surface to even everything out.

Let cool completely, then unmold and cut into slices.
