Ingredients

  • 250 g White Granulated Sugar (plain, fine)
  • 0.5 tsp Salt (fine sea salt)
  • 400 ml Coconut Milk (full‑fat, 14‑oz can)
  • 30 ml Coconut Oil (melted for sugar mixture)
  • 265 g Tapioca Starch (also called tapioca flour)
  • 15 g Rice Flour (plain white rice flour)
  • 2 tsp Double‑Acting Baking Powder (standard grocery store brand)
  • 6 large Eggs (room temperature)
  • 1.5 tsp Vanilla Extract (pure)
  • 2 tsp Pandan Extract (butterfly brand, green liquid)
  • 23 g Coconut Oil (liquid, added after final straining)

Instructions

  1. Preheat Oven

    Set the oven to 350°F (175°C) and place the pre‑oiled bundt pan on the middle rack to warm up.

    Time: PT5M

    Temperature: 350°F

  2. Melt Sugar and Coconut Oil

    In a saucepan combine 250 g sugar, 0.5 tsp salt and 30 ml coconut oil. Heat over medium‑low, stirring gently until the sugar fully dissolves and the mixture is smooth.

    Time: PT5M

  3. Add Coconut Milk

    Pour the 400 ml coconut milk into the sugar‑oil mixture. Stir and keep the heat on medium‑low until everything is fully incorporated and no sugar granules remain.

    Time: PT5M

  4. Sift Dry Ingredients

    In a separate bowl sift together 265 g tapioca starch, 15 g rice flour and 2 tsp double‑acting baking powder. Set aside.

    Time: PT2M

  5. Strain Eggs

    Crack 6 large eggs into a bowl, then push them through a fine mesh strainer into a large mixing bowl. Do this gently to avoid incorporating air.

    Time: PT2M

  6. Flavor the Eggs

    Add 1.5 tsp vanilla extract and 2 tsp pandan extract to the strained eggs. Fold lightly until just combined.

    Time: PT2M

  7. Combine Wet and Dry

    Pour the warm coconut‑milk mixture into the egg bowl, then add the sifted dry ingredients. Mix gently with a spatula until the batter is just incorporated; it will look slightly lumpy.

    Time: PT2M

  8. Strain the Batter

    Set a clean strainer over a large bowl and push the batter through in small portions, using a spatula to assist. This removes any remaining lumps.

    Time: PT5M

  9. Add Final Coconut Oil

    Microwave 23 g coconut oil for 10 seconds until liquid, then fold it into the strained batter gently.

    Time: PT1M

  10. Transfer to Bundt Pan

    Pour the batter into the pre‑oiled bundt pan, smoothing the top with a spatula.

    Time: PT1M

  11. Bake

    Place the pan in the preheated oven and bake for 45 minutes at 350°F. Do NOT open the oven for the first 30 minutes.

    Time: PT45M

    Temperature: 350°F

  12. Check Doneness

    Insert a cake tester or bamboo skewer into the center; it should come out clean.

    Time: PT2M

  13. Cool in Oven

    Turn the oven off, prop the door open with a wooden spoon, and let the cake cool inside for 15 minutes.

    Time: PT15M

  14. Release and Final Cool

    Remove the pan, invert the cake onto a wire rack, and let it cool completely (about 5‑10 minutes).

    Time: PT5M

  15. Slice and Serve

    Using a sharp knife, cut the cake into 8 wedges and serve at room temperature.

    Time: PT2M

Troubleshooting

Cake lacks honeycomb holes

Make sure the oven door stays closed for the first 30 minutes and avoid over‑mixing the batter.

Cake sticks to the pan

Grease the bundt pan thoroughly and consider using a non‑stick spray in addition to butter.

Batter is too thick

Add a tablespoon of coconut milk to loosen it; the batter should be pourable.

Freezer: Wrap tightly and freeze for up to 1 month; thaw in the fridge before serving.

Room temperature: Not recommended beyond a few hours; cake may dry out.

Make-Ahead Tips
