Though POWs typically steamed KLIM cakes due to lack of ovens, this is a historically faithful baked adaptation that captures the same texture and ingredients. It remains dense, simple, and symbolic of what a holiday treat meant inside a WWII Japanese POW camp.

1tablespoonsugaroptional but documented in Red Cross parcels
1tablespoonrice flour or finely crushed cooked rice
Pinchof salt
Instructions
Preheat oven to 325°F (165°C).
Mix powdered milk and water into a thick batter.
Stir in sugar, rice flour or crushed rice, and a pinch of salt.

Bake for 25 to 35 minutes until the top is set and lightly firm to the touch.
Cool for 10 minutes before slicing.
Notes
Texture: This cake will not rise or become fluffy. KLIM cakes were dense, chewy, and compact because prisoners relied on powdered milk and rice instead of flour, eggs, or leavening.
Flavor: The sugar is optional but historically accurate. Even a single spoonful would have been rare and often traded or saved for holidays.
Pan Size: Use the smallest tin or ramekin you have. Historically these were cooked in KLIM tins, so a small container produces the most authentic texture and shape.
