01 - Lightly spray a microwave-safe mug with nonstick cooking spray to prevent sticking.
02 - Add the angel food cake mix and water to the mug. Stir thoroughly until fully combined and smooth with no lumps.
03 - Place the mug in the air fryer basket. Cook at 320°F for 7-8 minutes until the cake has risen and is set in the center. Test doneness by inserting a toothpick—if it comes out clean, the cake is ready.
04 - Carefully remove the hot mug from the air fryer using oven mitts. Let cool for 1-2 minutes before topping with whipped cream and fresh berries. Serve immediately.
