In a medium mixing bowl, cream together butter, brown sugar, water and vanilla. Stir in flour and salt until fully combined. Gently stir in chocolate chips. Set aside.
Put regular rice krispies and cocoa krispies into separate bowls. Set aside.
In a medium saucepan, melt butter over low heat. Add marshmallows and stir until completely melted.
Pour half of the marshmallow mixture over the rice krispies and half over the cocoa krispies. Stir each bowl carefully until combined.
Scoop cocoa krispie mixture into the 9x13 pan. Press gently with the flat end of a wooden spoon or large spatula.
Crumble cookie dough over cocoa krispies and press down. Finally, add the rice krispie layer and press down to mesh layers. Sprinkle with mini chocolate chips, if desired.
Let cool and then slice into squares and enjoy!
