🕐How to make the Cosmic Crisp Apple Crumble
🍏🍎Get the apple filling ready
In a medium bowl, mix cut apples with lemon juice. Add vanilla extract and mix. Pour over apples. Transfer fruit mix into an 8 1/4-inch Pyrex glass baking dish. Place Pyrex in the Air Fryer and bake for 15 minutes at 350 degrees F.

▶️Prepare the crisp topping
In a medium bowl, combine the brown sugar, melted butter, all-purpose flour, and cinnamon until the mixture takes on a crumbly texture. Sprinkle it evenly over baked apples. Place in the Air Fryer and bake for 10-15 minutes or until topping gets light brown and is crispy. You can leave it longer in the Air Fryer if you want your crumble really crunchy. Serve warm with ice cream or whipped cream. Or you can cool completely before serving.

Try it for yourself!

Should I use light or dark brown sugar when making this Apple Crumble?
Light and dark brown sugar can both be used to make apple crisp, but there are some key differences between the two. Dark brown sugar contains more molasses than light or golden brown sugar, which gives it a richer, more robust flavor. If you prefer a bolder flavor, dark brown sugar is the way to go. However, if you want a more subtle sweetness, light or golden brown sugar will work just fine.
Here are some additional details about the differences between light and dark brown sugar:
Light brown sugar: Light brown sugar is made by mixing white sugar with a small amount of molasses. It has a light brown color and a slightly sweet, caramel-like flavor.
Dark brown sugar: Dark brown sugar is made by mixing white sugar with a larger amount of molasses. It has a darker brown color and a richer, more robust flavor.
