This classic chocolate lava cake recipe is a must-try for all chocolate lovers. The cake has a crispy exterior and a gooey, molten chocolate center that oozes out when you cut into it. To make this cake, you will need butter, chocolate, eggs, sugar, flour, and salt. Melt the butter and chocolate together, then whisk in the eggs, sugar, flour, and salt. Pour the batter into ramekins and bake for 12-14 minutes. Serve warm with a scoop of vanilla ice cream.
