Preheat the oven to 350°F (175°C).
Prepare the Jello: In a medium bowl, dissolve the strawberry Jello in boiling water. Stir well and allow it to cool to room temperature.
Make the Pretzel Crust: In a medium saucepan, melt the butter and mix in 1/4 cup sugar. Stir in the crushed pretzels.
Bake the Crust: Transfer the pretzel mixture to a 9x13-inch baking pan and press it evenly into the bottom using a fork. Bake for 10 minutes, then remove from the oven and allow to cool completely.
Prepare the Creamy Layer: Using an electric hand mixer, beat the softened cream cheese and 1/2 cup sugar together until smooth. Fold in the whipped topping until fully combined.
Spread the Cream Layer: Evenly spread the cream cheese mixture over the cooled pretzel crust, making sure to cover the entire surface. Refrigerate for 30 minutes.
Add the Jello Layer: Stir the sliced strawberries into the room-temperature Jello mixture. Pour it evenly over the cream cheese layer.
Chill and Set: Place the pan in the refrigerator for 2-3 hours, or until the Jello is fully set.
Serve and Enjoy! Slice into squares and serve chilled.
