In a medium bowl, crush the pretzel twists into coarse pieces.
In a separate bowl, combine the crushed pretzels, melted butter, and ¼ cup of granulated sugar. Mix well until combined.
Press the pretzel mixture evenly into the bottom of a 9x13-inch baking dish. Bake in the preheated oven for 10 minutes. Remove and let it cool.
In another bowl, beat the cream cheese with an electric mixer until smooth. Gradually add in the remaining ½ cup of granulated sugar and the powdered sugar until well blended.
Fold in the whipped topping gently until just combined.
Spread the cream cheese mixture evenly over the cooled pretzel crust.
In a small bowl, dissolve the strawberry gelatin mix in boiling water, stirring until fully dissolved. Allow to cool for a few minutes.
Add the sliced strawberries to the cooled gelatin, then pour this mixture over the cream cheese layer in the baking dish.
Refrigerate for at least 2 hours, or until the gelatin is firm.
Serve chilled, cutting into squares and enjoy this delightful treat!
