Preheat your oven to 350°F.
In a mixing bowl, combine the crushed pretzels, granulated sugar, and melted butter, stirring until the mixture resembles wet sand.
Transfer this mixture into a 9x13-inch baking dish, pressing it firmly to create an even crust.
Bake for 10 minutes, then set aside to cool completely.
In another bowl, whip the softened cream cheese and powdered sugar together until creamy and smooth.
Gently fold in the whipped topping until the mixture is light and fluffy.
Once the pretzel crust has cooled, spread the cream cheese mixture evenly over the top.
In a separate bowl, mix the boiling water with the strawberry gelatin, stirring until fully dissolved.
Allow this mixture to cool for about 10 minutes before adding the sliced strawberries, gently mixing to coat them in the gelatin.
Carefully pour the strawberry mixture over the cream cheese layer, ensuring an even distribution.
Place the dish in the refrigerator and let it chill for a minimum of 4 hours, or until the gelatin has completely set.
Once ready, slice into squares and serve chilled.
