Tension grows in a semifinal round of garden-inspired sweets, with two cooks duking it out for the remaining spot in the grand finale.

The judges ask 10 new cooks for dazzling desserts that are hiding a secret. Later, the bottom two must make a whimsical "I'm Not Lion" cake.

The next task is a tall order: edible towers that are at least 2 feet high. The two cooks who don't measure up must make Zumbo's "Lucky 13" cake.

The competition heats up with different takes on the ultimate ice cream sundae. Then it's on to Zumbo's "lazy" version ... which is anything but.

Kids take over the Dessert Factory for a colorful party-cake challenge. But the fun's over when Zumbo reveals a fruity test fraught with peril.

It’s a fight to the finish -- with smoke and mirrors -- as three hungry dessert makers compete for a golden ticket to the finals.

A dessert challenge with a timed bonus keeps the competitors on their toes. Later, the lowest scorers must make a layered cake -- a clock on a rock.

An out-of-this-world challenge sends the cooks' creativity sky-high. But a Zumbo Test of sobering difficulty brings two of them back down to earth.

The contestants' sweet creations take a dark turn with desserts that scream "fright night." And if they fail? A terrifying Zumbo Test awaits.

With their dessert dreams on the line, the finalists are ready to compete. But this time, the Zumbo Test comes first -- and it’s a doozy.
