The star of the show at the Lutz Café in Chicago is the Baumkuchen (tree cake), a 3-foot-tall tower of a cake baked in a rotisserie oven and coated in vanilla or chocolate frosting. On Kid in a Candy Store, Adam Gertler was impressed by its flakiness and buttery flavor.

iCream in Chicago serves classic treats with a hip twist: The ice cream is made with a blast of liquid nitrogen. When Adam Gertler visited the kitchen in Kid in a Candy Store, he was blown away that the ice cream in his PBOMG Sundae took less than a minute to freeze, thanks to this sweet science.

Come time for Halloween, the DeBrito Chocolate Factory has amped up the simple caramel apple into a treat chock-full of creative flavors. Adam Gertler's favorite had to be the caramel apple topped with cotton candy. But for those in need of a pick-me-up, try The Jolt! made with coffee toffee.

At Olsen's Danish Village, the traditional Kransekage cake (often seen at Danish weddings) has been a delightful spectacle for decades. Olsen's stacks 16 individual pastry rings, then drizzles icing on each layer. Although the cake is a showstopper, Olsen's offers other Danish goodies too.

As an absolute expert of edible drink straws and caramel marshmallows, Hammond's Candies is also home to the "heavyweight champion" of lollipops. They've been perfecting lollipops since 1920 and the giant Birthday Cake Lollipop beats them all — it's roughly 800 lollipops rolled into one.

This "sequel to street food" took Adam Gertler for a spin. Here, the humble cinnamon-sugar churro has been transformed into the gourmet "xooro" (pronounced sure-OH) and filled with dulce de leche and even custard. The gourmet flavors continue with toppings like toasted hazelnuts and bacon.

The chocolates at Eclipse Chocolate not only come in elegant designs and flavors, but they're a sustainable confection too. Eclipse uses only Guillard Chocolate for its signature Rocky Mountain chocolate bar, made with all-natural vanilla bean marshmallows and gray sea salt sprinkled on top.

With locations in Qatar and Turkey (and several in California), Yummy Cupcakes has truly brought its unique cupcakes to the world. The rotating menu features more than 280 flavors, like Green Tea Wasabi Cupcakes and Tomato Soup Spice Cupcakes, which are surprisingly moist, but mostly yummy.

These marshmallows aren't your typical s'more stuffer. At Plush Puffs, they've re-engineered the humble mallow into an artisan confection with flavors like caramel swirl, lemony meringue and chocolate chipetta. For big marshmallow fanatics, order "The Big One," a whopping 2-pound marshmallow.

The chocolatiers at Generations of Lee Gelfond Chocolate pack more than 15,000 chocolate molds into their bag of tricks -- one of the largest collections in the world. On Kid in a Candy Store, Adam Gertler didn't come for their tricks, but instead the giant white and dark chocolate haunted house.
