This is my first wedding cake. My niece asked me on Monday for a cake on Saturday. The cake was iced with buttercream icing. The Celtic Trinity Knot (behind the bride & groom cake topper) was made out of royal icing along with the roses & initials (LMP2 - the bride and grooom had the same initials) The leaves and acorns were made out of fondant dusted with bronze gold luster dust.
