These Are The World's Freakiest Milkshakes Slideshow

There are few better (or more fun) ways to cool down on a hot day than by indulging in a milkshake. Sweet, creamy, and (admit it) super-unhealthy, milkshakes are pretty much impossible to dislike. But over the past few years milkshakes have begun to morph into enormous, completely gut-busting monstrosities, and shops and restaurants around the world have begun to catch onto the trend.

There's a giant milkshake craze going on in Perth, of all places, and Babushka is seriously pushing some boundaries. Flavors include the very Australian Tim Tam & Coco Pop, Golden Gaytime with Gummi Bears (we'll have to look that one up), and the pièce de résistance: Triple Donut, Whiz Fizz, and Fairy Floss. Yes, those are doughnuts on that milkshake. And gummi worms. And chocolate-covered bacon.

Most Americans had never encountered an absurd milkshake before Black Tap launched theirs a couple years back, and people are still lining up to buy one, Instagram it, take a couple sips, then sit around wondering what to do with the rest of it. Options include Sweet N' Salty (chocolate frosted rim with chocolate gems and peanut butter cups topped with a Sugar Daddy, pretzel rods, chocolate covered pretzel, whipped cream, and chocolate drizzle); The Cookie Shake (vanilla frosted rim with cookie crumbles topped with a "cookiewich," crumbled cookies, chocolate chips, whipped cream, and chocolate drizzle); Sour Power (vanilla frosted rim with sour gummi poppers topped with a Pixy Stix, rainbow pop, sour skewer, whipped cream, and Nerds); and... and I'm exhausted.

This Peruvian restaurant has garnered a massive following for its crazy milkshakes, so much so that two new locations are in the works. Their shakes are available in Nutella, tres leches, cookies and cream, or one of several rotating varieties, and each one is different; don't be surprised if yours comes with an ice cream cone, brownie sundae, or piece of cake and a chocolate "syringe" perched on top.

This casual burger joint is serving some New England's craziest milkshakes — they call them "#FREAKFRAPPES" (naturally). The wildest offering is the "S'More Than You Can Handle," a frozen hot chocolate milkshake with a Graham cracker rim, chocolate syrup, and a "wicked big s'more."

Buns Bar has jumped on the insane shake bandwagon, and theirs are serious works of art. There are several rotating specials, but permanent menu items include Killa Vanilla (topped with tres leches cake), Death by Chocolate (topped with Grand Marnier-infused chocolate cake), and Gimme S'Mores (topped with s'mores).

This adorable shop with an adorable name sells some adorable milkshakes. The three year-old shop serves some pretty elaborate and whimsical shakes, including ones topped with matcha cake, candy, and ice cream comes filled with cotton candy.

Though it sounds like a place that might sell knockoff handbags, Cake Spade actually sells some wildly creative cakes, cupcakes, brownies, tarts, and what they call "cakeshakes." These come in Matcha Azuki, Mudslide, "Rodeo," and "Unicone" varieties, and each is insanely elaborate. The Mudslide, pictured, is topped with a cookie, a brownie, toasted marshmallows, caramel, and caramel popcorn.

If you were to hand us one of the ridiculous milkshakes served by Coney Waffle, we'd have no idea where to even start. These start out as tasty milkshakes, but the toppings are where it's at: Don't be surprised if yours comes topped with an ice cream cone, cookies, gummies, chocolate-covered pretzels, foil-wrapped chocolates, and a giant mound of cotton candy.

The Sour Green Monster, the Candy Carnival, the Chocolate Overload, and the Salted Caramel Delight are the names of a few of the crazy milkshakes on the menu at this South African restaurant. These elaborate, overflowing creations are just as wild as the name implies; the Salted Caramel Delight contains crème brûlée, caramel, chocolate, cheesecake, and salted caramel sauce, and the Oh Shake (pictured) contains banana, Nutella, and a giant slab of peanut butter fudge.

How about a milkshake made with chocolate, cotton candy, and cookie dough ice creams, topped with a chocolate chip cookie, a slice of chocolate cake, a brownie, an ice cream cone, cotton candy, sweet and sour candy, a Whirly Pop, marshmallow sauce, whipped cream, chocolate sauce, and sprinkles? The Candy Crush Belly Buster (pictured) at Cream & Sugar Café contains all that, and is just one of the seven "Freak Shakes" on the menu. If you want to customize your own here instead, they'll also let you do that.

This funky new doughnut shop has created some truly outrageous shakes, like the Rainbow Brite (topped with chocolate, candy, cake, cotton candy, a lollipop, and cotton candy); the 8th Wonder (topped with three doughnut cheeseburger sliders); and the Red Velvet (topped with cotton candy, red velvet fritters, and a big slab of red velvet cake). The offerings change every week, so you'll just need to keep coming back!

Naughty Boy's "Instashakes" are meant to be Instagrammed, as the name might imply, but judging by the descriptions they probably taste pretty good too. There's the Kinder Surprise (Kinder-inspired milk, white chocolate ganache, white chocolate mousse, mud cake, chocolate shards, and chocolate soil); the Caramel Éclair (salted caramel milk, Nutella, butterscotch filled éclair, caramel cream, and honeycomb pieces); and the Berry Cheesecake (berry 'cheesecake' milk, passionfruit curd, white chocolate mousse, freeze dried fruits, berry cheesecake, fresh berries), along with a weekly rotating special.

Patissez calls itself the "Home of the Freak Shake," and it indeed was one of the first places in Australia to supercharge milkshakes and help turn it into an international trend. Six FreakShakes are on offer at any given moment; the current lineup includes the Pretzella (fully loaded Nutella shake, salty pretzels,
Nutella, vanilla soft serve, and Nutella dunked pretzels), the King ( peanut butter white chocolate, maple bacon crumb, salted caramel, chocolate fudge, chocolate soft serve, cinnamon doughie bites, toasted marshmallow, and salted caramel injection), and the Nutcracker (paple roasted almond and pecan popcorn, salted caramel, vanilla soft serve, almond and pecan popcorn crown, and salted caramel injection).

This charming shop prides itself on its bespoke wedding cakes, but it also turns out some absolutely gorgeous (and delicious) milkshakes. These don't just stack a bunch of crazy stuff on top of a shake; these are actually meant to be eaten (and not just photographed) and contain really high-quality ingredients. One is topped with cookie crumbles, whipped cream, and an ice cream sandwich; another is topped with hot fudge, whipped cream, and a fudgy brownie; and a third is covered with caramel and popcorn, and topped with a slice of chocolate cake.

Fruit-filled and colorful milkshakes are on offer at this charming Perth bakery, including the Fruity Pavlova (mango milkshake with raspberry purée, topped with whipped cream, pink pavlova meringue, and raspberry and passion fruit jellies), and the Matcha-Rena (matcha milkshake with chocolate ganache, topped with chocolate mousse, pistachios, and a matcha-chocolate gelato pop).
