Preheat oven to 350 degrees. Spray a 9x13in pan with non stick cooking spray.

Next, combine butter, flour, powdered sugar and salt in a bowl until dough resembles small pea sized pieces.

Pat dough into bottom of the pan evenly.

Bake for 10 minutes.

Remove crust from oven, then start to prepare filling while crust is cooling.

For the filling blend eggs, sugar, flour, lemon juice, passion fruit puree and lemon peel until combined. Note it will be lumpy, but will smooth out during baking.

Pour filling over crust.

Bake for about 20 minutes or until the sides begin to loosen from the pan.

Allow to cool completely.

Right before serving, cut into bars and sift with powdered sugar. Serve immediately.
