While brownies are cooling, place 1/2 cup of the whipping cream in small saucepan. Sprinkle gelatin over cream; let stand 5 minutes to soften. Heat over low heat for 2 to 3 minutes or until gelatin has dissolved, stirring occasionally. Remove from heat. Stir in half of the crushed candies. Cool 20 to 25 minutes or until lukewarm, stirring occasionally. Most of candy will melt.
