  • Preheat oven to 350°F and spray an 8x8 baking dish with nonstick cooking spray.

Tips and Tricks
  • Leftovers: refrigerate any leftover bars- either in an airtight container or put plastic wrap over the dish you baked them in.
  • Cutting: To cut the lemon bars cleanly simply wipe down the knife you use to cut them after every cut.
  • Garnish: I highly recommend garnishing with  a little extra lemon zest!
