Paul Hollywood said "We want the bakers to make a chocolate caterpillar cake. The caterpillar should be made of a chocolate swiss roll sponge filled with a chocolate meringue buttercream and then coated in a silky-smooth ganache. The caterpillar should feature decorations to bring it to life."

​

The bakers were given 2.5 hours to complete the task.

Paul Hollywood "The trick is getting the bake of the swiss roll sponge just right. Overbaking it by just a minute will make it bone dry. Also, it's important to create the ridges and if the bakers follow the recipe, it steps them through the process. Inside there is a Swiss meringue buttercream and then a silky chocolate ganache on top.
