What You Need

My passionfruit slice recipe is made from basic pantry staples:

  • self-raising flour – use self-raising flour or make your own by sifting 2 teaspoons of baking powder through every 1 cup of plain (all-purpose) flour.
  • desiccated coconut – this is the fine coconut that you buy from the supermarket (not larger shredded coconut or coconut flakes).
  • caster sugar – also known as superfine sugar. This is a very fine white sugar.
  • melted butter
  • passionfruit pulp – small tins can be bought from the canned fruit aisle of the supermarket. Alternatively, you can use fresh passionfruit pulp.
  • sweetened condensed milk – use full fat sweetened condensed milk (not skim).
  • lemon juice – fresh or bottled lemon juice can be used.

How To Bake The Slice

This simple slice has two parts:

  • the cake-like base
  • the creamy passionfruit topping

Note: please scroll to the recipe card at the bottom of the post for ingredient quantities and the full detailed method.

Recipe Tips

To form the dough – the base mixture can be quite crumbly so I recommend using your hands to mix it together.

Pressing the mixture into the tin – use the back of a spoon or a round glass to press the mixture firmly into the baking tin.

Baking the base – cook the base until only just lightly golden around the edges.

Baking the slice – continue to cook the slice until the passionfruit layer has just set.

Cutting the slice – allow the slice to completely cool in the tin before cutting into slices.

Storing – this slice can be stored at room temperature for up to 4 days.

Freezing – this slice is not suitable for freezing.
