Notes

  • You don't have to grease the pan, but it doesn't hurt if you do. Use some cooking spray if you're concerned about easy cleanup.
  • Line a square baking pan with parchment paper so that the layers can be removed easily.
  • After baking, let the baking dish cool completely, then cover with foil and place in the refrigerator to chill before cutting with a knife.
