Preheat your oven to 400 degrees fahrenheit, and line a baking sheet with parchment paper.
In a medium mixing bowl, stir together crushed pretzels, melted butter, and 1/2 cup granulated sugar.
Spread the pretzel mixture in an even layer onto the parchment, and bake for 7-8 minutes.
Allow the pretzel mixture to cool completely, and break up into a crumble.
In a large mixing bowl, beat cream cheese until smooth.
Add in 1/2 cup granulated sugar, cool whip, and strawberry jello. Mix until well combined.
Fold in the fresh strawberries and pretzel crumble.
If desired, top with extra fresh strawberries or a bit of the pretzel crumble.
