Preheat your oven to 180 degrees and line a 28x18cm slice tin with baking paper - make sure you leave paper hanging over the sides to help you remove the Passionfruit Slice once it has cooked.
Place the flour, coconut, caster sugar and melted butter in a large bowl and stir to combine before using your hands to bring the dough together.
Transfer the dough to slice tin and use a metal spoon to press it down firmly over the base.
Place the slice into the oven and bake for 12 minutes or until light golden brown and set aside to cool.
Reduce the oven temperature to 150 degrees.
Use a whisk to combine the condensed milk, lemon juice and passionfruit pulp in a bowl
Pour and spread evenly over base
Bake for 15 minutes or until just firm to the touch.
Place the baked slice into the fridge for 2 - 3 hours or until it has completely cooled before cutting into squares to enjoy.
