From reading some old threads I've found that people here have had success with these substitutions in the classic Revolution Rolls:

Revolution Rolls made with mayonnaise instead of cream cheese (3 T mayo : 3 eggs). One person used half that much mayonnaise with success.

Revolution Rolls or Oopsie Rolls made with a nut butter or peanut butter in place of cream cheese (anywhere from [2 heaping T peanut butter : 4 eggs] to [6 T nut butter : 3 eggs]). Using the higher proportion of nut butter to egg makes the results drier and crispier.

Oopsie Rolls made with avocado instead of cream cheese. LCStudent (Lauren) did this and liked them but said they tasted a little avocado-y and thought they needed either onion/garlic powder or sweetener/cinnamon.

One recipe with a dairy-free substitution:
