I have made this dish for several years now. Everyone loves it. Whenever I go to a potluck I am asked to bring this dish. It can be used as a salad or a dessert. When used as a dessert, it is a refreshing change for a dessert with a sweet crunchy taste. This can be made the night before.
Place pretzels in food processor and process until small pieces are left. You can also crush them with a rolling pin if you don't have a food processor. Add powdered sugar and melted butter. Spread in a 13 x 9 pan. Bake at 350 degrees for 10 minutes. Cool
Mix the egg, powdered sugar, cream cheese and lemon juice together until well blended. Fold in cool whip. Spread over cooled pretzel layer. Allow to cool in refrigerator while you complete step three.
Dissolve jello in boiling water. Add frozen raspberries. Place in refrigerator for a few minutes to thicken. Spoon over top of cream cheese layer. Chill. Cut into serving sizes.
You can change this by changing the jello and fruit flavors. For example use strawberry jello and frozen strawberries, blackberry jello and frozen blackberries, peach jello and frozen peaches, etc.
