They're available with either two three-inch chocolate Oreo wafers or two "bakery-quality" chocolate chip cookies made with Nestle Toll House semi-sweet morsels, which sandwich a layer of Sonic's vanilla ice cream.
You can get one for $1.99. They're also available for $1.49 after 8 PM every night through September 2, 2019.
Carl's Jr. and Hardee's offered a similar concept (with both Oreo and chocolate chip cookie options) for a limited time back starting back in 2011.
