Prepare in advance
Shortbread base
Preheat the oven to 175° traditional heat. Butter a 20cm square mold. Line it with baking paper for easy unmolding.
In a food processor or with a stand mixer, beat the soft butter, brown sugar, flour, salt and vanilla to obtain a sandy mixture. Continue beating until the batter comes together and forms a paste.
Press this dough into the bottom of the mold. For ease, I put a baking paper on top before packing with the back of a tablespoon.
Bake 20 minutes. Let cool in the pan, on a wire rack.
Soft caramel (toffee)
In a saucepan, put the diced butter, brown sugar, sweetened condensed milk and honey. Heat over low heat for 15-20 minutes, stirring with a wooden spoon: do not stop mixing otherwise it will stick.
The mixture should take on a nice caramel color and become a little thick. Off the heat, add the vanilla. Pour this caramel over the biscuit base. Let cool then refrigerate for 45 minutes.
Chocolate ganache
In a saucepan, heat the cream and the chocolate in pieces over low heat, stirring to obtain a very smooth ganache.
Pour the ganache into the mold, over the cooled caramel, and refrigerate for 1 to 2 hours before cutting into 16 small squares. Sprinkle with fleur de sel (optional) for even more flavor.

Notes
This millionaire shortbread can be kept for about 4 days at room temperature in a bell jar or in the refrigerator. If you put it in the refrigerator, take it out 15 minutes before tasting so that it regains its texture and taste.
