Preheat your oven to 400 degrees Fahrenheit and line a baking sheet with parchment paper.
Mix the crushed pretzels, melted butter, and brown sugar in a bowl, then spread evenly on the baking sheet.
Bake for 7 minutes until caramelized. Let it cool completely on the counter, then break it into crunchy pieces.
Beat the softened cream cheese and granulated sugar in a large bowl with a hand mixer until smooth.
Fold the thawed whipped topping and diced strawberries gently into the cream cheese mixture using a spatula.
Combine the baked pretzel crunch into the creamy strawberry mixture right before serving to maintain the texture.
