Sultana & White Chocolate Shortbread

Beat the butter and sugar until creamy, approximately 2-3 minutes, add the sifted flour, when almost combined add the sultanas, choc chips & continue to beat with the flat beaters until a firm dough is obtained, be aware that it does take time to bring it together. If you knead by hand it will take approximately 4 minutes of kneading.
Wrap the dough in plastic and refrigerate for 30-60 minutes or even overnight.
Remove the dough from the fridge, and if very firm, gently knead, place the dough between 2 sheets of parchment paper and roll to ¼ inch thickness, cut out with your feastive cookie cutters, place on the prepared cookie sheets. Refrigerate the cookies while the oven is pre-heating, for about 15 minutes.
Pre-heat the oven to 160C. Line 1 or 2 cookie sheets with parchment paper.
Bake the cookies for approximately 10 minutes. Remove from the oven, let sit 2-3 minutes on the cookie sheet then move to a wire rack to cool completely.
Enjoy!
