Strawberry Pretzel Salad

I made this but pretzel curst didn't set up, it was a mess. Not going to make again

Took forever and the top isn't the jello consistency but still very good

Directions Preheat the oven to 400 degrees F (200 degrees C). Stir crushed pretzels, melted butter, and 3 tablespoons sugar together until well-combined; mix well and press mixture into the bottom of a 9x13-inch baking dish. Bake in the preheated oven until set, about 8 to 10 minutes; set aside to cool. Place cream cheese and 1 cup sugar in a large bowl. Beat with an electric mixer until smooth; fold in whipped topping. Spread mixture onto cooled crust. Dissolve gelatin in boiling water. Stir in still-frozen strawberries and allow to set briefly. Pour and spread over cream cheese layer; refrigerate until set, at least 2 hours.
