Are you sold! Once you try this recipe you will be in love with the flavours. This is an old-fashioned recipe that has been around since I was a kid. I used to make it as a teenager everytime the passionfruit vine was “overproducing”.

The recipe uses 130gm of passionfruit pulp so it’s particularly good if you need to use up a lot of passionfruit quickly. Plus, the resulting slice is so delicious it will magically disappear.

Simple Passionfruit Slice Method – Without Thermomix

Although the recipe is given for a Thermomix it’s super easy to make by hand.

  1. Melt the butter in the microwave, then add all the biscuit base ingredients to a food processor and process until you have a fine crumb.
  2. Press the crumb into a small baking tray.
  3. Refrigerate.
  4. With a whisk or stick blender combine the ingredients until they’re light and fluffy.
  5. Pour the filling over the base and bake for 12 minutes. Refrigerate for 2-3 hours.

Passionfruit Slice Tips

  • The total fruit pulp and juice needed is to equal approximately 250ml. You can change the ratio of passionfruit to lemon if you have an excess of either passionfruit or lemon.
  • Don’t overcook the slice, it needs to just barely be set. 12-15 minutes maximum depending on your oven.

    I used to make this recipe in the 1980s as we had a passionfruit vine growing in our garden & it always had heaps of fruit. I can’t believe we have to pay $1:50 each for these delicious fruits in the supermarket! Can’t wait to bake Julie.

    1. Julie Carlyle says:

      Awesome! I’m so pleased you’re excited. I can’t believe how expensive all the fruit and vegetables are, especially passionfruit!!! It’s so good when you have a neighbour with a vine 🙂

  2. Julie says:

    1- Would you be able to use canned passionfruit instead of fresh?

    2- if using just lemon do you use 245g of lemon juice or would that be too runny?

    Looking forward to making this and not sure if I prefer passion fruit or lemon so looks like I will have to make both 🙂

    1. Julie Carlyle says:

      Hi Julie
      Yes, you can use canned passionfruit instead of fresh 🙂 You should just use the recommended amount of lemon as it will taste too tart if you add more. The slice is best with the combination of passionfruit and lemon. I hope you enjoy the recipe.
      Happy cooking

    How long does this last in the fridge? I jave kids that dont eat this stuff ususlly 🙁 can i also freeze it?

    1. Julie Carlyle says:

      Hi, I imagine this will probably last about 5 days in the fridge. It can also be frozen 🙂
      Happy Cooking 🙂

    Made this for a friend who gave me a heap of passionfruit but they only ended up getting a quarter of it as it was divine. The only thing I found was the base too was crumbly so would use more butter next time. Someone also suggested using gingernut or butternut snap biscuits which I think I will try. Very easy to make and will definitely be a keeper.
