On a cutting board, trim the crusts off of the bread.
Press the bread slice flat with a rolling pin.
Using a small knife, trim the pressed bread's edges to make it look like a square.
Take a cannoli tube and wrap the flattened bread around a cannoli, sealing the edges with a little dab of water. Firmly press the edge of the bread that you just folded over.
Generously brush the rolled bread cannoli with ghee.
Repeat the process with the rest of the bread slices and form them into cannolis.
Arrange the ghee-coated bread cannolis in an air-fryer in a single layer.
Bake at 330°F for about 12- 15 minutes or until lightly golden. Rotate the cannolis halfway into the baking time.
When done, remove the cannolis from the air-fryer and let them cool for 5 minutes.
Gently twist the cannoli tube, and the bread cannolis will slide off the tubes.
Remove all the cannolis from the tubes and set them aside to cool completely.
