Preheat oven to 400°F (200°C). Line a baking sheet with parchment paper.
Mix together pretzels, melted butter, and 1/2 cup sugar.
Spread pretzel mixture on prepared baking sheet. Bake for 7 minutes.
Let pretzels cool and break into pieces.
Beat the cream cheese and remaining 1/2 cup sugar until smooth.
Fold in the drained pineapple and Cool Whip. Refrigerate for over 1 hour.
Mix in the pretzel pieces before serving. Enjoy!
Notes:
Save some pretzels to sprinkle on top for extra crunch. To keep the pretzels crispy for a long time, mix them in just before serving.
