The official state tree of Maryland is the white oak, which can live over 600 years! The leaves of this tree are very easy to pipe, and would look great in a variety of colors for a cake to celebrate any autumn holiday. You'll need stiff consistency royal icing, leaf tip #101 (or #104 for larger leaves), round tip #3, a glue stick, a flower nail, a Styrofoam brick, parchment paper squares, and a dusting pouch filled with a 50/50 mix of cornstarch and powdered sugar. Start by sticking a parchment square to the nail with a dab from the glue stick.
you might want to pipe some to accompany the leaves.
