Fluffy lemon filling on a buttery cracker crust.
Crush the crackers in a gallon size zip-lock bag. Pour into a medium bowl. Melt butter and pour into the crackers. Add powdered sugar and mix, reserving ⅔ cup for topping. Press the remaining mixture into a 9 x 13 inch pan.
In another mixing bowl, combine the frozen lemonade, sweetened condensed milk, whipped topping, and lemon juice until smooth. Spread over the cracker mixture evenly. Top with the reserved ⅔ cup. Refrigerate for 2-3 hours or over night.
