Step 1

To prepare the wax paper, measure the cake circumference and cut 2 strips of wax paper for that length. For 9-inch cake, I needed 2 15-inch strips. Height of the strips depends on the design you're planning, whether you want it the same height as your cake, or taller, etc. Just add an inch or so extra on top of the height of your design.

Step 2

Using a ruler and a pen, draw 2 lines on prepared wax papers that will guide you to draw the design.

Step 3

To melt the chocolate, place chocolate in microwave-safe bowl. Start with 1 minute at 50% power, stir well and microwave for another 30 seconds at 50% power. Repeat until chocolate is fully melted.

Step 4

Transfer the melted chocolate into a frosting bag with round tip.

Step 5

Start piping your design within the lines, making sure it's thick enough to stand. Too thin lines are too fragile.

Step 6

Set for 30-60 minutes at room temperature. Or  in a pinch, you can put it in a fridge, checking it every 5 minutes or so. It should be firm, but still pliable. You don't want the chocolate too hard, or it'll break.

Step 7

Carefully lift the wax strip with chocolate design, and wrap around the frosted cake. Repeat with the other side.

Step 8

Carefully peel off the wax paper. If the chocolate is a bit too soft, you can put the cake in fridge for 30 minutes, or longer, and then peel the wax paper off.
