Crush the pretzels using a food processor or by hand. This should yield 2 cups crushed.
Combine the crushed pretzels, butter and 1/4 cup of the sugar in a medium mixing bowl. Stir until the pretzels are coated with the butter and sugar.
Press the coated pretzel crumbs into the bottom of a 9 x 13 x 2 inch baking dish. Bake for 6-8 minutes. Remove the pretzels from the oven and allow them to cool completely.
Bring the lemonade to a boil in a medium saucepan over medium high heat. Add the strawberry gelatin and stir until the gelatin is dissolved.
Add two cups of cold water. Then remove the saucepan from the heat and set aside to allow the gelatin to cool completely.
In the mean time, whip together the cream cheese and the remaining cup of sugar until the cream cheese is fluffy.
Gently fold in the whipped topping. Then carefully spread the cream cheese mixture over the top of the pretzels.
Add the strawberries to the cooled gelatin. Pour the strawberry mixture over the cream cheese. Cover and chill for eight hours.
