The bottom tier is a rich fruit cake and the top tier is vanilla sponge; however you do have the choice to make both tiers vanilla sponge should you prefer.
The decoration of this lovely two-tier wedding cake is based on a Scottish theme... the cake topper is made by hand from a variety of silk floral elements, including thistles, heather, ivy leaves, rosebuds and bows of purple organza ribbon.
To finish the decoration process both tiers are wrapped with a 1" wide tartan ribbon.
Once coated with marzipan and icing, the cake dimensions are approx. 8 ½" diameter x 2 ½" high for the bottom tier and 6 ½" x 2 ½" for the top tier. The cake is then mounted on a coated ½" thick cake board and finished with a picot-edged satin ribbon.
