Method
Make and bake the shortbread crust
- Mix all-purpose flour, softened butter, granulated sugar, and salt until crumbly, using a pressing texture as the guide.
- Press the crumbly mixture firmly into an 8x8 baking dish to form an even, compact layer.
- Bake at 350°F for 12-15 minutes until the crust turns golden at the edges.
Add dulce de leche and chocolate, then bake again
- Spread dulce de leche over the warm crust in an even layer, keeping the surface level for glossy pooling.
- Melt dark chocolate chips with 2 tablespoons butter until smooth, then drizzle or spread over the dulce de leche in an even coat.
- Bake at 350°F for 8-10 minutes until the chocolate is set and no longer looks wet or shiny.
Cool, chill, and slice
- Cool completely at room temperature until the bars release their initial warmth.
- Refrigerate for at least 30 minutes to firm the caramel so the bars cut cleanly.
- Cut into 16 squares and sprinkle with fleur de sel.
- Serve at room temperature or chilled, letting the center become slightly gooey again if preferred.
Notes
For the cleanest squares, chill until fully firm before cutting, then wipe the knife between slices. Store covered in the refrigerator up to 4 days; freezing is yes—freeze squares in a single layer, then wrap for up to 2 months and thaw in the fridge. For a gluten-free option, swap in a 1:1 gluten-free all-purpose flour blend for the crust.
