Prep the pan: Heat your oven to 350°F (175°C). Lightly grease a 9x13-inch baking dish.
Crush the pretzels: Place them in a zip-top bag and crush with a rolling pin until you have small pieces and crumbs. You want texture, not fine dust.
Make the crust: In a bowl, combine crushed pretzels, melted butter, and 1/4 cup sugar.
Stir until the pretzels are evenly coated.
Bake the crust: Press the mixture firmly into the bottom of the baking dish. Bake for 8–10 minutes, then cool completely. Cool fully so the filling won’t melt.
Beat the filling: With a mixer, beat the softened cream cheese, 1/2 cup sugar, vanilla, and a pinch of salt until smooth and fluffy.
Fold in the whipped topping: Gently fold until combined and creamy. Don’t overmix—keep it light.
Spread the filling: Carefully spread the cream cheese mixture over the cooled crust, sealing the edges so the gelatin won’t seep down.
Chill for 30 minutes.
Prep the gelatin: Dissolve the strawberry gelatin in 2 cups boiling water. Stir until fully dissolved. Let it cool until just slightly warm and syrupy.
If you want a softer set, stir in up to 1 cup cold water once dissolved and then cool.
Add the strawberries: Stir sliced strawberries into the cooled gelatin.
Assemble the top layer: Gently pour or spoon the strawberry mixture over the chilled cream layer. Smooth it out evenly.
Chill to set: Refrigerate for at least 4 hours, or until the gelatin is fully set. Overnight is even better for clean slices.
Serve: Slice into squares with a sharp knife.
Wipe the knife between cuts for neat edges.
