Equipment

  • 1 round baking pan (7-8 inch diameter or 18-20 cm)

Ingredients

I highly recommend using a kitchen scale to measure.

  • 3 eggs (Size M)
  • 140 g tapioca starch
  • 10 g all-purpose flour (or rice flour or tapioca starch)
  • 240 g coconut milk (full-fat)
  • 5 g coconut oil (or melted butter) (about 1 tsp)
  • 180 g palm sugar
  • 4 g baking powder (double-acting or single-acting) (almost 1 tsp)
  • 2 g baking soda (almost ½ tsp)
  • ½ tsp salt
  • Cooking oil (for greasing the pan)

Instructions

Prepare the Batter

  • Lightly beat the eggs.
  • In a pot, gently heat palm sugar, salt, and coconut milk until smooth (don’t boil). Slowly whisk into the eggs and let cool for 15 min.
  • Whisk in tapioca starch and flour, then strain. Mix in baking powder, baking soda, and coconut oil. Strain again for a smooth batter.

Prepare the Mold & Bake

  • Grease the bottom of the mold only, then pour in the batter. Cover with foil if your oven can’t turn off top heat.
  • Preheat oven to 340°F (170°C), no fan, top heat off if possible, 15–20 min.
  • Place the cake on the second rack. Bake in stages:
    - 15 min at 340°F (170°C)
    - 30 min at 265°F (130°C), uncover (or turn on top heat)
    - Finally, 355°F (180°C), bake 15 min more until golden.

Cool & Enjoy

  • Let cake cool completely in the mold for easy unmolding.
  • Cut into bite-sized pieces. Enjoy on its own or drizzle with sweet coconut sauce (highly recommended!).
