Creamy Vanilla Custard Squares

Thicken the Cream – Heat over medium, stirring constantly and scraping the pan edges. Cook 5–7 minutes until thickened into a smooth, heavy cream.

 Finish & Assemble – Remove from heat and stir in butter, vanilla, and salt. Pour warm custard over the cooled crust and smooth the top.

 Chill & Set – Refrigerate at least 1 hour (2–3 hours recommended for cleaner slices) until custard is fully set.

 Serve – Lift out using parchment paper, slice into squares, and dust with powdered sugar just before serving.
