Chocolate orange shortbread biscuits are light, buttery, melt in your mouth cookies with chocolate and orange zest. They are perfect for making in bulk and freezing and are easy to make.
Mix the butter and sugar together until just combined. Don't overmix.
Sift the flour and cornflour into the bowl with the butter and sugar.
Add the orange zest and chocolate chips and mix until just combined. Again, don't overmix.
Roll the dough on a lightly floured pastry board to form a log about 4 centimetres (1.5") in diameter. Wrap in cling film and chill for at least 30 minutes.
Carefully remove the cling film. Cut the shortbread dough into slices about 1 cm (about 0.4") thick and place on a lined baking sheet.
Bake
Bake at 150oC, 300oF, gas mark 2 until they are just starting to turn golden at the edges (around 20 minutes) but check regularly to avoid overcooking. If you are baking in batches, chill the second batch before baking and do not reuse a baking sheet which is still warm.
Leave on the tray for about 5 minutes before transferring to a wire rack to cool.
Notes
Note
The preparation time noted in based on baking in a single batch.
To store
Store your chocolate orange shortbread in an airtight container for up to a couple of days.
For longer storage, freeze in an airtight container. The shortbread can be defrosted at room temperature or in a microwave.
Tips
Don't skip the chilling part. If the shortbread dough isn't chilled before baking it is likely to spread.
Remove the butter from the fridge so that is softens enough to mix easily.
Check after 10 minutes in the oven and then every 5 minutes until ready to avoid overcooking.
