Preheat the oven to 350°F (175°C). In a mixing bowl, combine flour, sugar, melted butter, and salt. Mix until crumbly.

Press the mixture into the bottom of a greased baking pan. Bake for 15-20 minutes or until lightly golden.

In another bowl, combine sliced strawberries, sugar, and lemon juice. Let sit for 10 minutes to macerate.

Spread the macerated strawberries evenly over the baked crust.

Bake for an additional 10-15 minutes until the strawberries are soft.

In a mixing bowl, whip the chilled heavy cream with powdered sugar and vanilla extract until soft peaks form.

Spread the whipped cream over the cooled strawberry bars before serving.
