Open your can of biscuits and separate them. Take 2 and put the rest back in the fridge
With the 2 biscuits, carefully separate them in half. So you have 4 discs or pizzas.
Brush on each of them some butter.
Add the marinara sauce, about 2 teaspoons per pizza
Sprinkle some of the cheese and top with pepperoni pieces.
Bake in the air fryer at 400 degrees F on a manual setting for 5-6 minutes or until the cheese is melted
Once they are done, put them on a cooling rack to cool while you cook the other ones.
Repeat steps 2 to 7 until you have 16 little pizzas.
