Step 1

Preheat oven to 400 degrees. Line a 9x13-inch baking pan with parchment paper.

Step 2

In a medium bowl, stir together pretzel pieces, butter, and 1/2 cup sugar. Transfer mixture to prepared baking pan. Press down gently on it and spread it out some. It does not need to cover the bottom of the pan.

Step 3

Bake for 7 minutes. Let cool.

Step 4

In a large bowl, use a hand-held mixer to beat cream cheese and remaining 1/2 cup sugar until smooth and creamy.

Step 5

Fold in Pineapple and Cool Whip. Refrigerate for at least 1 hour.

Step 6

Just before serving, crumble the pretzel mixture and mix into pineapple mixture. I like to reserve some of it to sprinkle on top.
