End your Valentine's Day dinner on a sweet note with a decadent molten chocolate lava cake. Mix together melted chocolate, butter, sugar, eggs, and flour to create a rich and gooey batter. Pour the batter into greased ramekins and bake until the edges are set but the center is still soft and molten. Serve the warm cakes with a dusting of powdered sugar and a scoop of vanilla ice cream. This indulgent dessert is the perfect way to end a romantic meal.
