In a large bowl, combine the melted butter and both sugars on a medium speed for 3-5 minutes, until fully incorporated.
Add in the egg and vanilla and mix until combined.
Add the flour, baking powder, baking soda and spices. Mix until totally combined into a soft cookie dough. Put this mixture into the fridge for at least and hour.
Preheat the oven to 200C/180C Fan/Gas 6. Line 2-3 large baking trays.
In a small bowl, mix together the cinnamon and sugar.
Once the cookie dough has chilled and firmed up a little, use a tablespoon to scoop balls of the dough. Roll into a ball then roll in the cinnamon sugar mixture. Place on the baking trays with about 2 inches apart.
Bake for 10-12 minutes, until they are golden and crisp at the edges. Let cool on a wire rack before eating!
