Stacey Solomon and Liam Charles present the quarter-final, and to begin with the teams must create 24 illusion desserts, tricking the judges into thinking they are about to eat hot dogs. They must also make their version of a childhood favourite for Cherish Finden - the Singapore ice-cream sandwich - all in three and a half hours. The chefs then face a rollercoaster ride of a challenge as they create sugar and chocolate theme parks, which must also incorporate desserts.
