Blueberry Squares with Passion Fruit Syrup

Blueberry Squares with Passion Fruit Syrup

This is one of the easiest cake to make if you have a lot of blueberries to use up. (Although that never happens in this house as all the kids are eating them by the punnets)

If you can’t source passion fruit, you can skip the syrup and it is still a very yummy cake for the afternoon. (Or you can replace passion fruit with lemon!) But passion fruit has this amazing aroma that makes you feel like you’re on holiday, which is what we’re all after being stuck at home!

  • Put icing sugar and passion fruit juice in a saucepan and heat gently until sugar dissolves.
  • Prick the warm cake with a fork all over, the spoon the syrup evenly over the surface.
  • Leave cake to cool completely in the tin, then cut into 9 squares.

To serve

  • Top the squares with the reserved blueberries and dust with icing sugar (pour over leftover syrup if you have any left).

  • Hi Annie

    I am sure this recipe is originally from a cookbook which I owned long time ago but lost it.
    Would you please tell me the name of the cookbook?
    Thank you!


    • Hi Matilda, yes you’re right! Unfortunately I don’t have the book anymore as I made some tweaks before I purge my cookbooks. I remember it had lots of pictures in it… sorry that’s no help!

    • I haven’t tried freezing this myself but I’d say you can, before putting syrup on top. You can make the syrup in advance and freeze the cake, once cake is thoroughly defrosted, add syrup on as you normally would. Enjoy!
