Dissolve the Gelatin In a large mixing bowl, pour the boiling water over the strawberry Jell-O gelatin. Stir continuously until the gelatin is completely dissolved with no visible granules.

Add Cold Water Stir in the ice cold water until fully combined. The mixture should begin to cool slightly but remain liquid.

Chill Briefly Allow the gelatin mixture to sit at room temperature for a few minutes until it thickens slightly but does not set.

Fold in Cool Whip Gently fold the thawed Cool Whip into the gelatin mixture until smooth and evenly colored. Take care not to overmix to keep the filling light and fluffy.

Fill the Crust Pour the strawberry mixture into the graham cracker pie crust, spreading it evenly with a spatula.

Refrigerate Until Set Place the pie in the refrigerator and chill for at least 2–3 hours, or until fully set and firm.

Garnish and Serve Before known, garnish with fresh strawberries if desired. Slice and serve chilled.
