Step 1

Dissolve the Jell-O in the hot water by stirring until crystals are no longer visible.

Step 2

Add the frozen orange juice concentrate and stir until completely melted. Add the juice from one of the cans of mandarin oranges, then stir in the oranges from all three cans.

Step 3

Pour into a large glass dish and transfer to the refrigerator to chill until completely set, about 4 hours.

Step 4

Combine the instant vanilla pudding mix and cold milk in a bowl and whisk well until it starts to set up, about 1-2 minutes. Note that this recipe does not use the same amount of milk as directed on the package of pudding. Fold in the Cool Whip or whipped cream, then spread over the top of the set Jell-O.

Refrigerate until ready to serve.
