In a large bowl, combine the cream, eggs, sugar, and the lemon extract. Whisk until well combined.
Add the blueberries, cream cheese, and the cubed croissants. Toss gently until everything is thoroughly combined and set aside.
Pour the croissant mixture into a 6 cup bundt pan, distributing it evenly accross the pan. Place the pan in the air fryer basket.
Set the Ninja Foodi function to Air Crisp and the temperature to 350 degrees F. Air Crisp or fry for about 60 minutes, or until the custard is set in the middle.
Allow to rest for about 10 minutes before unmolding it onto a serving pan.
Serve and enjoy.
Notes
The original recipe calls for an additional 3 tablespoons of sugar with these instructions: Place the bundt pan in the air fryer basket. Preheat the air fryer to 400 degrees F. Sprinkle the 3 tablespoons of sugar in the bottom of the hot pan. Set the air fryer to 400 degrees F for 10 minutes, or until the sugar caramelizes. Tip the pan to spread the caramel evenly accross the bottom of the pan. Then you would continue with adding the bread pudding mixture and following the rest of the steps. As mentioned in the post, I skipped this step and this recipe is still fantastic without it!
