This ice cream sandwich truck specializing in custom cookie-wiches can be found most days (all day) at Klyde Warren Park, but check their schedule for details before you head out. Possible cookie and ice cream combinations range from classic (chocolate chip with vanilla) to rather eccentric (potato chip-butterscotch with fried chicken and waffles). [Photo: Coolhaus]

Henry's provides ice cream to a ton of different restaurants in the Metroplex, but for the ultimate selection, head to the retail location in Plano, where you'll find go-to favorites like cinnamon, butter pecan and chocolate chip served alongside more, er, experimental flavors such as sweet corn, licorice, and avocado. There's a reason Henry's has been going strong for 25-plus years now. [Photo: Henry's]

This old-fashioned soda fountain has been serving Dallas since 1912, and it remains a favorite place to stop in for a sweet treat. Ice cream cups and cones are available, but best bets are the sweet, rich milkshakes in flavors like butterscotch, chocolate and strawberry, or for something a little lighter, the orange freeze made with sherbet.

Tucked away in a Plano strip mall next to a Starbucks is this small shop offering some of the most unique ice cream flavors you'll find in DFW. Think lychee, almond-pistachio-saffron, custard apple, Thai tea, Thai coffee, oolong tea and falooda, which contains rose flavoring. (If there are picky eaters or kids in your group, they also have flavors like cookies and cream or bubblegum.) [Photo: Old Town Creamery/Facebook]

At least in Dallas, Paciugo has become synonymous with gelato. Yes, it's a (rather large) chain -- since opening its first Dallas store in 2000, the gelato masters at Paciugo have since grown to 40-plus locations -- but it's also creamy, dense and comes in a huge array of rotating flavors ranging from chocolate-hazelnut and balsamic strawberry to candy-colored rose and violet. It also has about 70 percent less fat than regular ice cream, if that kind of stuff matters to you. [Photo: Paciugo/Facebook]

This friendly, independently-owned scoop shop in Richardson's II Creeks development is very popular with the locals for its fresh, housemade ice cream in flavors like bourbon vanilla, salted caramel, coffee toffee, mint Oreo and more. No sundaes or fancy toppings here, just straight-up cups and cones. [Photo: Sweet Firefly/Facebook]

This retro Knox Street shop has been serving hot dogs and frozen custard since 1996, and it's the extra-high butterfat percentage that makes the custard so damn good -- super smooth, rich and creamy, like the fattening lovechild of fro-yo and pudding. Chocolate and vanilla are always available along with a rotating selection of other flavors like hazelnut fudge, butter pecan, coconut and cookies 'n cream. It's plenty good on its own, but feel free to gild the lily by adding toppings such as pecans, sprinkles or graham crackers, or opting for a hot fudge-smothered sundae.

Walking into this adorably old-school ice cream parlor in Denton's downtown square, you're immediately struck by the sweet scent of freshly baked waffle cones. Indecisive types beware: The selection of housemade flavors here is mindbogglingly expansive, from classics like mint chocolate chip and butter brickle to more unusual creations such as Bees Knees (lavender and honey). Besides regular old scoops, there's also malts, shakes, ice cream sodas, and phosphates. [Photo: Dan H./Yelp]

When this trendy popsicle shop opened last summer, the line was out the door practically every day. Fresh fruit popsicles in unusual flavors like blood orange and pineapple jalapeno are refreshing on a hot day, but for something more in the vein of traditional ice cream, look to the creamy pops in flavors like chocolate peanut butter, coffee, avocado, and tangy buttermilk.

Aaron Barker's ice cream shop now has bigger, better digs in Oak Cliff. A rotating selection of flavors could include selections like cookie butter, banana pudding, or even Shiner Bock; the Rice Krispy treat ice cream sandwiches are always a good bet, and if you really feel like getting wild, there's also Twinkie strawberry shortcake.

This brand new entrant into the ice cream scene is a great addition to the Dallas Farmers Market. Owner Mark Wang has an engineering background, and he's engineering some seriously good, intensely flavored ice cream with 12 percent butterfat. Chocolate fiends will flip for the Callebaut dark chocolate in a housemade waffle cone, but do also try the more unusual flavors like basil lemongrass. Check their Facebook page to keep tabs on their schedule. [Photo: Roomies/Facebook]
