Carina from Bristol discovers that there is a hole in her plan to make a chocolate balloon. Meanwhile, Karl hopes to win over the judges with his Angel of the North.
Challenged to produce chocolates based on their favourite desserts, two contestants choose tiramisu as their inspiration. The Bikers visit the Quality Street production line.
The hopefuls go supersize and bite-size in two exciting rounds. New-fangled chocolate toys lead to meltdowns, before the contestants try to wow with a grab-bag of morsels, from boozy bubbles to amaretto waves.
The semi-final sees the contestants creating Easter eggs chock-full of treats. However, they quickly find themselves treading on eggshells as they try to meld two fragile white chocolate hemispheres together.
In the final of the contest, the remaining three contestants produce three different versions of their signature chocolate bars, before the final two compete for mass production of their recipe.
