Crush the Oreo cookies, by placing them in a bag and pounding them with your hand or kitchen tool.
Fold the Oreo Cookies into the prepared batter.
Pour the batter into a prepared bundt pan, that fits inside your Air Fryer Basket.
Set the timer for 15 minutes at 320 degrees F.
After the 15 minutes check the status of your cake, by using a toothpick and inserting it in the middle of the cake, if it comes out clean remove the cake. If it doesn't add 5 minutes to your time, and repeat until the cake is baked through.
Remove the cake from the Air Fryer Oven, and let the cake rest.
In a small bowl pour the chocolate chips and shortening in it. Then place it in the microwave for 30 seconds, remove it from the microwave and mix well. Repeat for another 30 seconds if the chocolate is not melted.
