Preheat the oven to 175°C. Grease a 115–125 ml oven-safe ramekin and set aside.

In a small saucepan over low heat, melt the chocolate chips and unsalted butter, stirring continuously until completely smooth. Alternatively, combine in a microwave-safe bowl and melt in 20-second intervals, stirring after each, until smooth.
03 -
In a separate mixing bowl, whisk together the egg, egg yolk, granulated sugar, pure vanilla extract, and a pinch of fine sea salt until thoroughly combined.
04 -
Add the all-purpose flour to the wet ingredients and whisk gently, ensuring minimal clumping.
05 -
Pour the melted chocolate-butter mixture into the flour and egg mixture. Fold gently with a spatula until a uniform batter forms.
06 -
Transfer the prepared batter into the greased ramekin. Place the ramekin on a baking tray and bake for 14–20 minutes, until the surface is just set but the center remains soft. Monitor closely to avoid overbaking.
07 -
Allow the cake to rest for 1 minute, then invert onto a plate or serve directly in the ramekin. Top with a scoop of vanilla ice cream and enjoy immediately.
