Preheat oven to 375° F.
Combine flour, baking soda and salt in small bowl. Beat butter, granulated sugar, brown sugar and vanilla extract in large mixer bowl until creamy. Add eggs, one at a time, beating well after each addition. Gradually beat in flour mixture. Stir in morsels and crushed Mini Oreos, saving some whole Oreos to place on top of cookies after baking. Use a cookie scoop to drop dough onto cookie sheet. I did two scoops for larger cookies.
Bake for 9 to 11 minutes or until golden brown. Sprinkle more chocolate chips, Mini Oreos, and rainbow sprinkles on top. Cool on baking sheets for 2 minutes, and then place on wire racks to cool completely.
