The kid bakers must create carnival-themed cupcakes using carnival treats.

Valerie and Duff task the 11 remaining kid bakers with creating volcano Bundt cakes that spew smoke and edible boulders. The red-hot challenge will test these amazing bakers to their fiery core!

In an ode to the outrageous psychedelic colors of tie-dye, Valerie and Duff head back to the 1960s and ask the remaining nine kid bakers to "color them wow" with mind-blowing cakes.

The remaining 10 kid bakers must create a comfort food dessert imposter -- meatloaf, fried chicken, mac and cheese and more -- to keep their place at the table.

The remaining six kid bakers create mobile app icons out of sugar cookies and explain what each app does to the judges.

For the finale, the last three kid bakers have to create an original superhero cake and describe their superhero's powers during tasting. Who will win this last challenge and fly off with $25,000?
