This molten Nutella lava cake is a decadent dessert that combines the rich flavors of chocolate and Nutella. The recipe is simple and requires only a few ingredients, including butter, chocolate, eggs, sugar, flour, and Nutella. The Nutella is swirled into the batter before baking, creating a molten center that oozes out when you cut into the cake. Serve it warm with a scoop of vanilla ice cream for the ultimate indulgence.
