• Measure your butter and sugars and add them to a mixing bowl. Mix them together until soft and creamy. (You can also use your mixer if you want).
  
• Add in your egg and vanilla, and mix in.
  
• Sieve in the plain flour, baking powder, bicarbonate of soda, and a pinch of salt.
  
• Mix together to form a cookie dough.
• Stir in your chocolate chips, along with the M&Ms, Smarties or coloured chocolate beans.
  
• Use an ice cream scoop to portion the cookie dough. (Mine is about 5cm and makes about 12 or you can divide it into 8 and have larger cookies).
  
• When the cookies are rolled place them in the fridge for at least 30 minutes. (You can also freeze them at this point).
  

Freezing your cookie dough

• Once you have made your cookie dough balls you can put them in a freezer bag and freeze them for a later date.
  

Cooking your air fryer Christmas NYC cookies

• (You might need to do a few batches if you want to do all the cookies together. If they are chilled you can cook a few when needed.)
• Place the cold cookie dough balls on a sheet of baking parchment / greaseproof paper in the air fryer.
• Make sure they are spaced out as they will spread when baking.
• Bake in the air fryer at 170ºC / 338ºF for 10-12 minutes depending on size until they are golden brown.
  
• Leave the cookies to cool and they are ready to enjoy.
  

Cooking your Christmas NYC cookies from frozen in the air fryer

• Place the frozen cookie dough balls on baking trays with baking parchment / greaseproof paper.
• Make sure they are spaced out as they will spread when baking. You might need to do them in batches. I can cook 4 cookies at a time in my air fryer.
• Bake in the air fryer at 170ºC / 338ºF for 12-15 minutes depending on size until they are golden brown. They need a little longer from frozen and you might want to give them a gentle press halfway through if you want them to be thinner.
• Leave the cookies to cool and they are ready to enjoy.
