Raspberrry Pretzel Dessert or Salad

This dish always gets so many compliments! It looks really pretty too!

2 cups mashed pretzels
1/2 cup melted butter
2 Tablespoons sugar
8 oz. cream cheese (softened)
1 cup sugar
9 oz. Cool Whip
1 6 oz. Raspberry Jello
10-16 oz. bag frozen berries (I use raspberries)
1 3/4 cup boiling water

In a 9x13 glass pan, mix mashed pretzels, butter and 2 T. sugar together until well blended. Press down and cook for 10 minutes at 350 degrees. Let cool completely. Mix cream cheese, 1 cup sugar, and Cool Whip until well blended. Frost over the pretzel, making sure to cover all the edges so the Jello layer doesn't seep into the crust. Put in freezer to chill. Dissolve Jello in boiling water, add frozen berries. Pour on top of cream cheese layer and spread. Cover and refrigerate until Jello is set or overnight for best results.
