Preparation Using electric mixer, beat cream and orange juice concentrate in medium bowl until stiff peaks form. Place 8 cookies on rimmed baking sheet, spacing apart. Spoon about 1 level tablespoon whipped orange cream atop each cookie, then top each with second cookie and another tablespoon cream. Repeat 2 more times with cookies and cream, creating 8 stacks of 4 cookies with 4 layers of orange cream. Top each stack with fifth cookie. Transfer remaining orange cream to small bowl; cover and chill cream. Cover and chill stacks at least 6 hours or overnight (cookies will soften). Carefully transfer 1 stack to each of 8 plates. Rewhisk reserved orange cream, if necessary, until stiff peaks form. Spoon dollop of orange cream atop each stack, sprinkle with grated orange peel, and serve.
