Lastly, turn off the mixer, add the cheese using wooden spatula. Be gentle pls.
Set aside in the fridge for 30 min to 2 hours before baking. Dough is kinda sticky and yummy ( I cant help myself.. I licked my fingers every time..)
Then you can start baking.. A tbsp per cookie is fine but mine, I use ice cream scoop for a big cookie!
