¼cup/ 60ml buttermilk or use substitute SEE NOTE 1
1 ¼cup/ 150g all purpose / cake / plain flour
2Tablespoons/ 30ml milk
FOR THE TOPPING
395gcan / 14 oz sweetened condensed milk
½cup/ 125ml fresh lemon juice
¼cupcanned or fresh passionfruit pulp
Instructions
TO MAKE THE BASE
Preheat the oven to 350°F (175°C) fan or 360°F (180°C) conventional.
Grease and line an 8 inch / 20cm pan with parchment / baking paper allowing the sides to overhang.
Using an electric beater, beat the butter, sugar and vanilla in a bowl until pale and creamy. Beat in the buttermilk or plain yoghurt. If you do not have buttermilk then just add 1 teaspoon lemon juice to a ¼ cup of milk. Leave it aside for 5 minutes to allow it to curdle. Use this mixture instead of the buttermilk in the recipe.
Fold in the flour and milk and mix until smooth.
Spoon the mixture into the prepared pan. Use the back of a metal spoon to spread and press evenly over the base of the pan. Bake for 15 minutes or until a skewer inserted into the centre comes out clean. Remove from the oven.
TO MAKE THE TOPPING
Use a whisk to combine the condensed milk, lemon juice and passionfruit in a bowl until smooth. Pour the condensed milk mixture over the base.
Bake for 15 minutes or until firm to the touch. Set aside to cool completely. I usually just place the tin into the fridge for an hour or freezer for 30 minutes to speed up the cooling and setting process. Then cut into slices to serve
