Half a teaspoon of salt

Firstly, preheat the oven to 180 degrees Celsius. In a large bowl, cream together the butter, brown sugar and white sugar until it becomes light and fluffy. Add the vanilla extract and then the eggs one at a time, beating well. Combine the salt, cocoa, flour, baking powder and baking soda and gradually stir until a consistent creamed mixture has formed. 

Shape the dough into balls which are the size of your palm and place on a greased baking tray. Flatten the dough slightly with the bottom of a drinking glass. Bake for 8-10 minutes or until the cookies look puffy and the tops are cracked but still soft. Remove from the oven and allow to cool completely. 

For the filling, remove the Gookie Dough from the fridge and allow it to soften slightly and then put all of the contents of Gookie Dough in a medium bowl along with the marshmallow fluff and vanilla extract. With an electric mixer, mix the ingredients together until a fairly thick mixture has formed. 

When assembling the sandwiches, you need to scoop three teaspoons (maybe more) of filling onto the bottom of a cooled cookie and top with another cookie. ENJOY! *Recipe credit and adapted from Heat Oven to 350*
