Method
Make the shortbread crust
- Preheat the oven to 350°F and line an 8x8 baking dish if desired for easy lifting.
- Mix all-purpose flour, softened butter, granulated sugar, and salt until the mixture looks crumbly, then press firmly into the bottom of an 8x8 baking dish.
- Bake at 350°F for 12-15 minutes until the crust turns golden at the edges and set in the center.
Add dulce de leche and chocolate
- Spread the dulce de leche evenly over the warm crust so it reaches the corners.
- Melt the dark chocolate chips with 2 tablespoons butter, then drizzle or spread it over the dulce de leche for a thick, even layer.
- Bake again at 350°F for 8-10 minutes until the chocolate is set and looks glossy on top.
Cool, chill, and slice
- Cool the bars completely to room temperature so the caramel thickens and the layers hold together.
- Refrigerate for at least 30 minutes so the bars firm up for clean cuts.
- Cut into 16 squares, then sprinkle with fleur de sel and serve at room temperature or chilled.
Notes
For the ooey texture, use a warm crust to help dulce de leche spread smoothly, and cool fully before slicing so layers don’t smear. Store covered in the refrigerator for up to 4 days; freeze up to 1 month (thaw overnight in the fridge). For a dairy-light option, you can try a plant-butter substitute and dairy-free chocolate, but texture may be slightly softer.
