Give your cake a dramatic look by placing it on a base board covered with fondant. Cut cake boards 2 in. larger in diameter than your cake, unless otherwise directed, then roll out fondant about 1 in. larger than board size. Wrap board with foil.
Steps
step 1 – coat board
Lightly coat foil-wrapped board with piping gel to help the fondant stick to the foil.
step 2 – roll & drape fondant
Roll out fondant to desired size, 1/4 in. thick. Position over board using a rolling pin, draping fondant over edge.
step 3 – smooth top & sides
Trim excess fondant from edges under bottom of board. Smooth top and sides with Easy-Glide Smoother.
