This a French Chocolate Silk Pie inspired cookie.
First we start with chocolate cookie base. It is loaded with dark chocolate chips, semi-sweet chips, and chocolate Oreos. It's filled with a fluffy dark chocolate marshmallow buttercream. The cookie is topped with a dollop of whipped white frosting and a fluffy chocolate marshmallow fudge. The whole cookie is coated in a chocolate hardshell and a Hershey bar chunk.
