Made from a 65-year-old recipe that includes custard and shake milk, the chocolate shake at Connie’s Frozen Custard is the creamery’s most popular drink.

The shake has an egg yolk base and is gluten-free. Diners can choose from more than 30 toppings or seasonal mix-ins to create a unique shake flavor.

Owner Melissa Ashby said she first learned about custard from a Missouri-based shop before bringing the ice cream alternative to the Greater Houston area. Connie’s serves a variety of custard concoctions, including concretes, sundaes and malts.

“Custard is creamier, denser and has less air than normal ice cream, which makes it so good,” Ashby said.

The chocolate shake comes in two sizes—16 ounces or 24 ounces—which cost $3.89 and $5.38, respectively.

Connie’s has been serving Cy-Fair residents for the past 16 years at its location on Jones Road.
