Start by melting the butter (I used a microwave-safe bowl) and microwaved it until melted.
Mix in the chocolate chips.
Mix until the chocolate chips are melted.
Mix in the unsweetened cocoa powder.
Add in the sugar.
Add the rest of the ingredients in.
Mix well.
Spread into an air fryer safe pan, and bake at 320 degrees F, air fryer setting, for 25 minutes.
Let cool, before adding the icing.
In a large mixing bowl, mix the cream cheese, and butter. Then mix in the vanilla, and powdered sugar, mix until smooth.
Spread the icing over the cooled brownies, and then crush up the Oreos and sprinkle on top
Plate, serve, and enjoy!
