Melt butter and chocolate (break it into pieces first) in a microwave-safe bowl. Stir every 20 seconds, it should be ready in about 1 minute.
Take another bowl (a large one), and using an electric beater- beat the egg, egg yolk, sugar, and vanilla extract. Continue mixing until the mixture is well blended.
Add the chocolate mixture, flour, and salt to the egg mixture, and mix well until combined.
Grease 3 ramekins, and pour the batter inside each.
Air fry at 380F (190C) for 7-10 minutes. Remove the ramekins from the air fryer (be careful- they will be hot!) and let cool for a minute. Loosen the cake from the ramekin (I used a knife) and turn it over onto a serving plate.
