Yoyo Cookies with Creamy Passion Fruit Filling

Cookies:
175g unsalted butter, softened
115g confectioners’ sugar, sifted
2 teaspoons finely grated lemon zest
265g all purpose flour, sifted
35g corn flour (cornstarch), sifted
1/3 cup (80ml) passion fruit pulp

Filling*:
125g unsalted butter, softened
150g confectioners’ sugar, sifted
¼ cup (60ml) passion fruit pulp

Preheat the oven to 160ºC/320ºF; line two large baking sheets with baking paper.

To make the filling, place the butter and sugar in the bowl of an electric mixer and beat for 6-8 minutes or until pale and creamy. Strain the passion fruit pulp through a sieve to remove the seeds. Add to the butter mixture and beat for further 3-4 minutes or until smooth. Set aside.
Make the cookies: place the butter, sugar and lemon zest in the bowl of an electric mixer and beat for 6-8 minutes or until pale and creamy. Add the flour, corn flour and passion fruit pulp and mix in slow speed until combined. Roll 1 rounded teaspoon of the mixture into balls with damp hands and place on prepared sheets – if the mixture gets a little sticky, refrigerate it for 15-20 minutes. Press each cookie with a damp fork to flatten. Bake for 12-15 minutes or until light golden. Allow to cool on sheets.
Sandwich the cookies together with the passion fruit filling to serve.

* I was pretty generous filling the cookies and still got loads of filling left. I believe half the recipe would be enough.
