Preheat your Air Fryer at 375 for 3 minutes.
In a large mixing bowl, whisk your flour, baking powder, baking soda, and salt. Set aside.
In a separate large bowl, whisk together your butter and sugar.
Add eggs, milk, and vanilla to your butter and sugar bowl. Mix.
Add in your flour mixture. Mix.
Add in 1 cup of your chocolate chips. Fold in.
Place your silicone molds in the air fryer. Add your muffin mixture to the mold 3/4 of the way. Top with a few chocolate chips (about 3-6 chips per muffin according to your liking).
Sprinkle with some sparkling sugar.
Cook at 375 degrees F for 10 minutes or until golden brown. I suggest also sticking a toothpick in the middle of one muffin, and if the stick comes out clean (no batter), it is done!
Allow muffins to cool. Then enjoy!
