A luscious dessert combining the richness of chocolate with the boldness of red wine.
Preheat your oven to 350°F (175°C).
Ensure the oven is fully preheated for even baking.
Combine the chocolate cookie crumbs and melted butter in a mixing bowl until evenly mixed.
Mix thoroughly to ensure the butter coats all the crumbs.
Press the mixture into the bottom of a springform pan to form an even crust.
Use the back of a spoon to press the crumbs firmly into place.
Bake the crust in the preheated oven for 10 minutes, then let it cool completely on a wire rack.
Cooling the crust prevents it from becoming soggy when the filling is added.
Heat the heavy cream, red wine, sour cream, and sugar in a saucepan over medium heat, whisking constantly until the sugar dissolves and the mixture begins to bubble around the edges.
Whisking constantly prevents the mixture from scorching.
Pour the hot cream mixture over the chopped chocolate in a bowl and let it sit for 30 seconds.
Letting it sit allows the heat to melt the chocolate evenly.
Whisk the mixture gently until smooth and glossy.
Whisk gently to avoid incorporating air bubbles.
Pour the chocolate filling into the cooled crust and spread it evenly with a spatula.
Spread evenly for a smooth and professional look.
Refrigerate the tart for at least 4 hours to set.
Chilling allows the flavors to meld and the filling to firm up.
Slice and serve the tart, garnished with fresh berries or a dollop of whipped cream if desired.
Serve chilled for the best texture and flavor.
