Preheat your oven to 325°F (160°C). Grease a 9-inch springform pan and line the bottom with parchment paper.

Melt butter and chocolate:

• In a medium saucepan, melt the butter and chopped dark chocolate over low heat, stirring frequently until smooth and well combined. Remove from heat and let cool slightly.

Prepare the batter:

• Stir in the granulated sugar, salt, and vanilla extract into the chocolate mixture until well incorporated.
• Add the eggs one at a time, mixing well after each addition until the batter is smooth and glossy.

Bake the cake:

• Pour the batter into the prepared springform pan and smooth the top with a spatula.
• Bake in the preheated oven for 35-40 minutes, or until the top is set and a toothpick inserted into the center comes out with a few moist crumbs attached.

Cool and serve:

• Allow the cake to cool in the pan for about 10 minutes, then run a knife around the edges to loosen it. Remove the sides of the springform pan and let the cake cool completely on a wire rack.

Optional garnish:

• Dust the top of the cake with cocoa powder or powdered sugar before serving.
• Serve slices of the cake with fresh berries or a dollop of whipped cream, if desired.
