Pour melted butter straight in a 9 inch pan.
Preheat oven to 375 degrees F.
In a 9 inch pan, pour melted butter along with the sugars and combine with a spatula or wooden spoon.
Add the egg, vanilla extract and mix.
Next, dump all the dry ingredients and mix until incorporated.
Fold in chocolate chips and spread the batter smooth. The cookie dough will be sticky so I use a piece of parchment paper to push the dough to the edge of the pan.
Bake the Pizookie at 375 degrees F for 10 minutes or until lightly golden brown around the edges but a bit under baked in the center.
Top with vanilla icecream and a nice drizzle of melted chocolate and enjoy!
