Melt the butter and in a bowl, mix the melted butter, sugar, brown sugar together.
Add in the maple syrup, egg and vanilla extract and mix together.
Mix in the flour, baking soda, baking powder and cornflour.
Finally mix in the chocolate chips and dried cranberries and place the mixture in the fridge for at least 30 minutes. I waited around 40 minutes.
Preheat the oven to 180°C (350°F) and line a baking tray with baking paper.
Roll the chilled dough into balls and place on the tray.
Bake for around 10-12 minutes. The cookies will have spread slightly, the top will have a very slightly golden look to it and they will be soft to the touch.
Allow the cookies to cool for 10 minutes before devouring!
