Chicago never sleeps, and neither does your sweet tooth. When midnight munchies strike or date night runs past dinner, finding the perfect dessert spot can feel impossible. Fortunately, the Windy City offers amazing dessert counters that keep their doors open well into the evening, serving everything from classic sundaes to gourmet cookies when you need them most.
1. Margie’s Candies — Bucktown & Ravenswood

Step into a time machine where sundaes reign supreme and hot fudge flows like liquid gold. This century-old institution has been satisfying Chicago’s sweet cravings since the 1920s, earning its reputation as a true dessert temple.
Order the legendary Royal George sundae and watch servers pour hot fudge from an actual silver gravy boat. The spectacle alone makes it worth the visit, but the taste keeps people coming back generation after generation.
Weekend warriors can indulge until 1:00 a.m. at the original Bucktown location, while the Ravenswood shop closes earlier but still offers that same magical experience.
2. Firecakes Donuts — River North (walk-up window)

Forget everything you know about late-night donuts. Firecakes elevates the humble pastry into an art form with small-batch creations that taste like they were made by your favorite grandmother.
Their donut ice cream sandwiches blur the line between breakfast and dessert in the most delicious way possible. Each bite combines warm, pillowy dough with cool, creamy ice cream that melts perfectly in your mouth.
The River North location keeps night owls happy with midnight closes Wednesday through Saturday. Their convenient walk-up window means you can grab these treats without even leaving your car.
3. Insomnia Cookies — Old Town (and other neighborhoods)

Sometimes the name says it all. Insomnia Cookies understands that cookie cravings don’t follow normal business hours, which is why they’ve built their entire brand around serving warm treats when everyone else has closed.
Their signature warm chocolate chip cookies arrive at your table still gooey from the oven. Pair them with cold milk or upgrade to an ice cream sandwich for the ultimate comfort food experience.

5. The Original Rainbow Cone — Navy Pier

Five flavors stacked like edible architecture create Chicago’s most Instagram-worthy dessert. The Rainbow Cone isn’t just ice cream; it’s a colorful monument to the city’s playful spirit and sweet traditions.
Each layer tells a story: chocolate for richness, strawberry for sweetness, Palmer House for local pride, pistachio for sophistication, and orange sherbet for that perfect tangy finish. The combination sounds crazy but tastes like genius.
Navy Pier location keeps the magic alive until 11:00 p.m. on Saturdays and 10:00 p.m. on Fridays. Nothing beats walking the pier with this iconic treat, watching the city lights reflect off Lake Michigan while savoring each colorful bite.
6. JoJo’s ShakeBAR — River North

Maximalism meets milkshake magic at JoJo’s, where bigger is always better and restraint is a foreign concept. Their creations defy gravity and common sense in the most delicious way possible.

7. Ghirardelli Ice Cream & Chocolate Shop — Michigan Ave/Wrigley Building

Tourist trap or late-night treasure? Sometimes both labels fit perfectly, especially when hot fudge sundaes are involved. Ghirardelli’s Michigan Avenue location delivers reliable sweetness when downtown adventures run past dinnertime.
Their hot fudge sundaes follow a time-tested formula that hasn’t changed because it doesn’t need to. Premium ice cream meets warm chocolate in portions generous enough to share (but you probably won’t want to).

Midwest comfort food reaches its frozen peak at Andy’s, where custard concretes and jackhammers provide the perfect antidote to Chicago’s unpredictable weather. This isn’t just ice cream; it’s a regional obsession with serious scientific backing.
Their concretes blend frozen custard with mix-ins until achieving the perfect consistency – thick enough to turn the cup upside down without spilling. Jackhammers take things further, creating treats so dense they require industrial-strength names.
The West Lawn location near Midway keeps drive-thru service running until 11:30 p.m. on weekends. Perfect for airport runs or late-night sugar emergencies when only the richest frozen custard will do.
9. JARS by Fabio Viviani — West Loop

Celebrity chef Fabio Viviani transformed dessert presentation by putting gourmet treats into mason jars, creating Instagram-perfect portions that taste even better than they photograph. Each jar contains layers of culinary artistry.
Tiramisu, Oreo, and red velvet variations showcase classic flavors with modern technique. The transparent jars reveal beautiful layers of cake, custard, and creative toppings that make choosing almost impossible.
Weekend hours stretch to midnight on Friday and Saturday, giving West Loop night crawlers plenty of time to discover their new favorite dessert format. These portable treats prove that good things really do come in small packages – or in this case, perfectly sized jars.
