Instead of bowls filled with bite-size chocolate bars and sugary sweets, treat guests with grown-up, dressed-up cocktails at Halloween parties and events. Here's a look at some scarily good concoctions.

To modernize an old-fashioned, BLT Steak Atlanta infuses Whistle Pig bourbon with Werther’s Original hard candies and combines it with sweet vermouth and aromatic bitters. A bourbon-macerated cherry and a crushed sea salt rim garnish the drink.

For Halloween, the Lollipop Brew at the Sugar Factory American Brassiere in Miami Beach comes dressed up with gummy snakes, spiders, and brains, along with lollipops and a candy necklace. The cocktail, which is served year-round minus the extra creepy crawlies, contains a wicked mix of Monin cantaloupe syrup, Bacardi coconut rum, Ketel One Citroen, grenadine, and pineapple juice.

As an homage to surrealist artist René Magritte, guests sipped on "Magritte-Ahhs," a concoction of cotton-candy clouds, tequila, agave, and lime-kaffir salt at the Woman's Board and Board of Trustees gala in June 2014 at the Art Institute of Chicago.

For a sweet twist on a simple cocktail, BLT Steak Atlanta mixes Red Vine-infused Stoli vodka with club soda and garnishes the glass with a strawberry and strands of the licorice candy.

The vintage ice cream parlor theme of Washingtonian magazine's annual AT&T's Best of Washington party, held at the National Building Museum in July 2012, inspired the blue rock candy drink stirrers in the signature cocktail, which was called the AT&Tini.
