Flavor Variations

Coconut Twist

Tips for Success

  • Use real passion fruit pulp (fresh or frozen) for the best flavor
  • Let the curd cool completely before assembling
  • Level your cake layers with a serrated knife for a stable stack
  • Use a turntable and offset spatula for a clean ganache finish
  • Let the assembled cake set in the fridge before slicing

Make-Ahead and Storage

  • Cake layers can be made 1–2 days ahead and stored wrapped at room temp
  • Passion fruit curd keeps in the fridge for 4–5 days
  • Ganache can be made a day ahead and rewarmed gently
  • Assembled cake lasts 3–4 days refrigerated — best within 48 hours

Frequently Asked Questions

Can I use passion fruit concentrate instead of fresh pulp?
Yes, but choose one with no added sugar and dilute slightly if very strong.

Can I make this cake gluten-free?
Use a 1:1 gluten-free flour blend for the cake layers.

Is the white chocolate too sweet?
The tang of passion fruit balances it well — use dark or semi-sweet chocolate if you prefer less sweetness.

Yes. Wrap slices tightly and freeze for up to 1 month.
