Description

An elegant dessert featuring a crisp chocolate pastry shell filled with rich salted caramel and topped with airy chocolate mousse domes—finished with a dusting of cocoa powder and a chocolate garnish for a refined presentation.


Ingredients

Units Scale
  • 1 1/4 cups all-purpose flour
  • 1/4 cup unsweetened cocoa powder
  • 1/4 cup powdered sugar
  • 1/2 cup cold unsalted butter, cubed
  • 1 egg yolk
  • 12 tbsp cold water
  • 1/2 cup sugar (for caramel)
  • 2 tbsp water (for caramel)
  • 1/4 cup heavy cream (for caramel)
  • 1/4 tsp sea salt
  • 2 tbsp unsalted butter (for caramel)
  • 1 cup heavy cream (for mousse)
  • 1/2 cup dark chocolate, chopped
  • 1 tbsp sugar (for mousse)
  • 1 tsp vanilla extract
  • Cocoa powder (for dusting)
  • Dark chocolate disc or shaving (for garnish)

Instructions

  1. Preheat the oven to 350°F (175°C).
  2. In a bowl, mix flour, cocoa powder, and powdered sugar. Cut in cold butter until the mixture becomes crumbly.
  3. Add egg yolk and cold water until the dough comes together. Press into a tart pan or molds. Prick the base with a fork and chill for 15 minutes.
  4. Bake for 18–20 minutes or until the tart shell is firm. Let cool completely.
  5. For the salted caramel, combine sugar and water in a saucepan. Cook over medium heat until the mixture turns golden amber.
  6. Remove from heat and carefully whisk in the cream, salt, and butter. Let the caramel cool slightly, then pour into the baked tart shell. Chill until set.
  7. Melt the dark chocolate and let cool slightly. In a separate bowl, whip the heavy cream with sugar and vanilla to soft peaks.
  8. Fold the melted chocolate into the whipped cream until smooth and fluffy.
  9. Pipe the chocolate mousse over the chilled caramel layer and chill until fully set.
  10. Before serving, dust with cocoa powder and top with a dark chocolate disc or shaving.

Notes

  • Ensure the caramel is fully cooled before adding mousse to prevent melting.
  • Chill the tart shell before baking to help prevent shrinkage.
  • Use high-quality chocolate for best flavor and texture.
  • Tart can be made a day in advance and stored in the fridge.
