Stir in the eggs and the chocolate sauce, and then mix well.
Take another bowl and combine the flour with the baking soda and hot chocolate mix. Then, add the dry ingredients to the wet ingredients, and mix until well combined.
Place silicone baking cups in the air fryer. Fill them with batter.
Air fry them for 12-15 minutes. Insert a toothpick into the center of the cupcakes. If it comes out clean – they are ready.After removing them from the air fryer – let them cool for at least 5-10 minutes, and then add frosting on top.
