Cut the bread into cubes and melt the butter.

Sprinkle cheese powder over the bread, then gently mix in the granulated sugar. Gradually drizzle the butter over the bread and mix gently (do not pour all at once, as the bread absorbs butter quickly).

Bake for 8 minutes at 320-340°F in an air fryer (check and stir after 4 minutes, then continue baking for another 4 minutes). Let cool and store in a container for later enjoyment.
