In a bowl, mix melted butter and Saltine crackers until combined. Press crust into a 9” or 10” pie plate (I used a deep dish 9” pie plate). Refrigerate for at least 10 minutes.
Wash and remove the strawberry stems. Cut the strawberries into chunks. Pat strawberries dry with a paper towel.
In a bowl, mix cream cheese and marshmallow fluff together.
Stir in the strawberries and mini marshmallows.
Gently fold the Cool Whip into the cream cheese filling, folding until everything is combined.
Spoon cream cheese mixture into the pie crust. Refrigerate for at least 4 hours up to 24 hours.
Store any leftovers, covered in the refrigerator for up to 2 days. The crust will start getting soggy after that.
