3 ounces white baking chocolate, melted and cooled
4 teaspoons lime juice
1 teaspoon grated lime zest
1 cup heavy whipping cream
2 tablespoons confectioners' sugar
1/2 cup cream-filled chocolate sandwich cookie crumbs
Black decorating gel
In a large bowl, beat cream cheese until smooth. Gradually add white chocolate, lime juice and peel; mix well. Set aside.
In a small bowl, beat cream until it begins to thicken. Add confectioners' sugar; beat until stiff peaks form. Gently fold into cream cheese mixture.
Sprinkle cookie crumbs into four dessert dishes, 2 tablespoons in each. Using a large round pastry tip, pipe white chocolate mixture into ghost shapes onto cookie crumbs. Add eyes and mouths with black decorating gel. Serve immediately.
