1 cup sugar
3/4 cup butter
1 can (5-oz) evaporated milk
2 pkgs (12-oz each) white chocolate morsels
1 jar (7-oz) marshmallow cream
3 cups coarsely crushed cream-filled chocolate sandwich cookies (about 25 cookies), divided
pinch of salt
Line a greased 9-inch square pan with aluminum foil leaving enough foil to later lift fudge from pan, set aside.
Combine the sugar, butter, and evaporated milk in a medium saucepan; cook over medium-high heat, stirring constantly, until mixture comes to a boil. Cook 3 minutes, stirring constantly. Remove from the heat.
Add the white chocolate morsels, marshmallow cream, 2 cups of the crushed cookies, and the salt; stir until the chocolate morsels melt.
Pour the fudge into the prepared pan. Sprinkle the remaining cup of crushed cookies over the fudge and press gently into fudge. Cover and chill until firm (approximately 1 to 2 hours).
Using the foil, lift the uncut fudge from the pan to a cutting board. Remove foil and cut fudge into squares.
