Ingredients
Method
- Beat softened butter, confectioners’ sugar, and cocoa powder in a stand mixer until smooth and creamy. Add the egg yolk and vanilla, mixing just until combined.
- Sift the flour into the chocolate mixture and mix on low until a soft dough forms. Press evenly into a 10-inch tart pan and shape up the sides.
- Preheat oven to 350°F (175°C). Line the crust with foil and add pie weights. Bake 15 minutes, remove weights, and bake another 10–15 minutes until dry and firm. Cool completely.
- Combine sugar, water, and corn syrup in a heavy saucepan. Boil, swirling occasionally, until medium amber. Remove from heat and whisk in butter, cream, crème fraîche, and salt. Pour into cooled crust and let set 1 hour.
- Place chopped chocolate in a bowl. Heat cream until just boiling and pour over chocolate. Rest 1 minute, then whisk smooth. Pour over caramel and tilt to coat. Chill 1 hour and finish with fleur de sel.
Notes
Dust fingers with cocoa when pressing dough to reduce sticking. For deeper caramel flavor, cook slightly darker but avoid burning. Sour cream can replace crème fraîche. If the glaze seizes, whisk in warm cream.
