It's a Ferris Wheel of fails as the teams make treats with a state-fair theme; from caramel corn knockdown-doll clowns to roller coaster cakes.

Baking duos go off the deep end with desserts inspired by the wonders of the ocean, including marine animal mini cakes and enormous edible octopuses.

Candy-jeweled brooch cookies? Inviting cookie-jar cakes? These sugary sweets are just like the ones Grandma used to make - if Grandma couldn't bake.

From splashy cereal-bowl cakes to towering hamburgers with fries, these attempts at hyperrealistic treats are so bad, you won't believe your eyes.
