Be sure to start this recipe one day before.

1. In a bowl or electric mixer, beat butter, brown sugar, raw sugar, vanilla essence and egg until evenly combined.
2. In a separate bowl, combine the plain flour, corn flour, baking powder and bicarbonate of soda.
3. To make the cookie dough, gradually add the flour mixture and oil to the butter mixture and stir until well combined.
4. Fold in the zest of two oranges and chocolate chip with a spatula/spoon until well mixed. Cover with plastic wrap and refrigerate overnight.
5. Preheat oven to 180 degrees Celsius and line baking trays with parchment paper.
6. Scoop tablespoon-sized balls of cookie dough (roughly 4cm) and space them evenly on the baking trays, leaving space for spreading.
7. Bake them for 10-12 minutes or until golden brown (you may need to bake them in batches depending on your oven and tray space – if so, keep the dough refrigerated between batches)
8. Once baked, let cookies cool for 5 minutes on the tray before transferring to a wire rack to cool completely.
9. Serve with fresh strawberries and store excess cookies in an airtight container or cookie jar.
