Method
Make the shortbread crust
- Mix all-purpose flour, butter, granulated sugar, and salt until the mixture looks crumbly.
- Press the crumbly mixture firmly into an 8x8 baking dish to create an even, compact layer.
- Bake at 350°F for 12-15 minutes until the crust turns golden.
Layer dulce de leche and chocolate
- Spread the dulce de leche over the warm crust in an even layer.
- Melt the dark chocolate chips with the 2 tablespoons of butter, then drizzle or spread over the dulce de leche.
- Bake at 350°F for another 8-10 minutes until the chocolate is set.
Chill, slice, and serve
- Cool completely at room temperature before chilling to help the layers set cleanly.
- Refrigerate for at least 30 minutes so the bars hold their shape.
- Cut into 16 squares, then sprinkle with fleur de sel.
- Serve at room temperature or chilled for the gooey caramel texture.
Notes
For the cleanest slices, cool completely and chill until firm (at least 30 minutes). Store covered in the refrigerator for up to 4 days; freeze cut bars in a single layer for up to 2 months, thaw in the fridge overnight. For a dietary swap, use a plant-butter substitute in the crust and chocolate layer for similar structure and flavor.
