Preheat the oven to 400°F (200°C). Grease a 6-cup muffin tin with butter or non-stick baking spray and place it on a baking sheet.
Melt the chocolate and butter together in a double boiler or in the microwave. Stir until completely combined.
In a medium bowl, whisk together the sugar, eggs, cocoa powder, vanilla extract and salt until combined. Slowly add the melted chocolate mixture and whisk until combined.
Divide the batter evenly among the muffin cups. Bake for 15 minutes, until the edges are set and the center is still slightly wobbly.
Let the cakes cool in the tin for 10 minutes before transferring them to a cooling rack. Serve warm with a dollop of whipped cream or a scoop of ice cream. Enjoy!
