Preheat oven to 350°F (175°C). Line a baking pan with parchment paper, leaving overhang for easy removal. In a bowl, mix melted butter, sugar, vanilla, and salt. Stir in flour until a thick dough forms. Press evenly into the prepared pan and bake for 15-18 minutes, until lightly golden. Remove and allow to cool slightly.

Combine cranberries, water, and sugar in a saucepan. Simmer over medium heat for 8-10 minutes, stirring occasionally, until berries burst and mixture thickens to a sauce-like consistency. Allow to cool briefly before spreading evenly over the baked crust.

Return the pan to the 350°F (175°C) oven and bake for 25-30 minutes, until the center is just set and no longer jiggles when gently shaken. Cool completely at room temperature, then refrigerate for at least 2 hours or overnight for clean slices.

Using the parchment overhang, lift the bars from the pan. Dust with powdered sugar just before serving. Cut into squares with a sharp knife, wiping the blade between cuts for pristine edges.
