Wrap in plastic wrap; freeze in a single layer overnight. For chocolate sauce, in a small saucepan, combine the water, cocoa and sugar; bring to a boil over medium heat, stirring constantly. Reduce heat; simmer for 2-3 minutes or until thickened. Remove from the heat; stir in butter until melted. To serve, dust brownie hearts with confectioners' sugar and drizzle with warm chocolate sauce. Store sauce in the refrigerator.
