Step 1: Prepare the Crust Begin by combining 1 1/2 cups chocolate wafer crumbs with 4 tablespoons melted butter. Press this mixture evenly into a 10-inch tart pan. Bake it for 10 to 12 minutes, then let it cool completely this takes about 15 minutes of prep time and ensures a sturdy base with great texture contrast to the ganache.

Step 2: Make the Ganache Heat 1 1/2 cups heavy cream until it simmers, then pour it over 12 ounces of roughly chopped dark chocolate. Let it sit for a few minutes before whisking until smooth, and stir in 4 tablespoons butter until fully mixed. This step, which takes around 10 minutes, creates the rich, creamy filling that makes this chocolate truffle tart so irresistible.

Step 3: Assemble and Chill Pour the ganache into the cooled crust and refrigerate for at least 2 hours until it sets firmly. Once set, sprinkle 1 tablespoon flaky sea salt on top for a flavor boost. If you want to add the optional whipped cream, mix 1 1/2 cups heavy cream with 1/2 teaspoon vanilla bean paste, a pinch of salt, and sugar to taste, then whip until soft peaks form.

Final Touches For clean slices, dip your knife in hot water, dry it, and cut this tip helps keep everything neat. The total time is about 25 minutes of active work plus chilling, making it perfect for busy professionals. Remember, using high-quality chocolate really makes a difference, as noted in the recipe details.
