Chocolate Cosmos Wedding Cake
Make Fondant Lamb's Ears
Tint 1/2 pound fondant pale green. Lightly dust a work surface with cornstarch. Roll a 2- to 3-inch ball of fondant 1/16 inch thick. Quickly cut out as many leaves as possible with a small leaf cutter (1 3/4 by 1 1/8 inches); immediately imprint with a leaf veiner. Gently bend leaves for a natural shape. Continue until you have about 40 leaves. Let dry on a baking sheet, about 3 to 4 hours; lightly brush with petal dust.Advertisement
Prepare Chocolate Fondant
Knead modeling chocolate until soft and malleable. Divide in half; wrap each in plastic. Divide 7 pounds rolled fondant in half. On a surface lightly dusted with cornstarch, knead half of fondant until soft and malleable, then knead with one of the chocolate halves until fully combined; cover with plastic wrap. Repeat with remaining fondant and chocolate halves. Knead both portions together to form one disk. Wrap in plastic; store at room temperature until ready to use.
Cover the Cake Board
In a small bowl, stir together the corn syrup and 2 tablespoons warm water. Thinly paint the mixture over the top of the petal cake board. On a clean surface lightly dusted with cornstarch, roll enough chocolate fondant to cover the board (see the fondant amounts at the end of the ingredients list) into a large disk about 1/8 inch thick. Working quickly, center and gently lay fondant on the board, smoothing it with your hands. Trim edges with a sharp paring knife. (Excess fondant may be reused if it is free of crumbs, filling, or icing.)
Cover the Tiers
Thinly coat each tier with the desired frosting to seal in the crumbs, then chill 30 minutes. On a surface lightly dusted with cornstarch, roll enough fondant to cover each respective tier, working with one tier at a time. Working quickly, center and gently lay fondant on tiers. Starting from the center, smooth it with your hands. Trim any excess fondant from bottom edge with a pizza cutter. Set tiers aside, preferably in a cool room; do not refrigerate.
In a small bowl, stir the meringue powder with 3 tablespoons of water until the powder dissolves. Working with one tier at a time, set each onto a large sheet of waxed paper; quickly brush the top of the tier with the meringue-powder mixture, and dust it with white sanding sugar. Brush off any excess sugar. Repeat process to coat the cake board.
Stack the Tiers
Lightly brush the center of the cake board with water; center and place the 15-inch tier on top. Insert 6 wooden dowels in a circle about 4 1/2 inches inside the edge of the tier. Moisten the center of the 15-inch tier; place the 9-inch tier on top. Insert the remaining 4 dowels in a 3-inch square in the center of the tier. Lightly brush the center of the tier with water; center and place the 6-inch tier on top.
Just before displaying cake, arrange the cosmos in miniature bouquets; tie with the white ribbon. Set cake on display table; randomly arrange bouquets on top of each tier and around cake board, inserting fondant leaves into bouquets. With hot glue or double-sided tape, secure brown ribbon around board, overlapping ends in the back.
