The ten competing bakers celebrate the spring equinox by first making colorful and delicious doughnuts themed to either sunrise or sunset.

There are shooting stars, the Milky Way, the Northern Lights, meteor showers and more.

It's raining cats and dogs as the nine competing bakers make "kittyclairs" -- eclairs with an orange kitty theme. Then they play puppy games, making desserts with sporty themes like a kayaking poodle and a tennis-loving Labrador.

It's team challenge week, and the eight bakers grab a buddy to spring into the outdoors. First, they bake tasty hand-held treats for a hike.

Spring is the time to clean and streamline, so the six remaining competitors make minimalist creations that are both flourless and flower-less. Then the bakers choose a crafted item from a funky yard sale and use it as inspiration for a gorgeous dessert

It's all things spring and flower-centric when the five remaining bakers are assigned cherries, cherry blossom decor and a crumble dessert to combine into a fabulous floral fusion. Then the competitors work with an ever-popular trend to create flower-crown cakes.

It's Mother's Day, and Mom takes a spring vacation to celebrate. Inspired by Mom's favorite cocktail, the four remaining bakers create sweet, spicy margarita madness desserts. Then the competitors make look-alike baked goods based on Mom's pool float, choosing between flamingo, swan, seahorse or peacock.

The pressure mounts in the Spring Baking Championship finale as the three remaining bakers celebrate graduation day by making an honor roll dessert and a diploma dessert with a dipping sauce.
