Cosmic Treats & Sweets is operating on Pittsburgh Street in Mars, adding an ice cream stop to the northern Pittsburgh region’s small-business mix. Its official website now posts daily hours and an image-based menu, while earlier reporting documents the business’s arrival during 2026.

This October 13 guide combines current visitor information with clearly dated opening background. It is a menu and planning overview, rather than a new October ribbon-cutting announcement or a review based on a personal visit.

An earlier opening, with a local family connection

In a July 29 Butler Eagle report, William Pitts described Cosmic Treats as an extension of the Purvis family’s businesses, including fuel distributor Purvis Brothers and Planet Mart convenience stores. The shop sits beside a Planet Mart in a building previously occupied by Mars Pizza, which the report said had moved to Grand Avenue.

The Eagle reported a June 24 start. A later September 17 Butler Radio item described an official opening that day. The reports do not explain the relationship between those milestones, so this guide does not assign an independently verified grand-opening date. The established point is that the shop was already operating when the July story appeared.

Owner Mac Purvis Jr. told the Eagle that the ice cream used a base from Marburger Dairy. The newspaper also described hard ice cream, soft serve and the Supernova blended dessert. Those are attributed details from the earlier report, rather than sourcing or production independently inspected by The Pittsburgh Wire.

Current hours, rotating flavors and menu choices

The official website, checked October 13, lists 509 Pittsburgh Street, Mars, PA 16046, with daily hours of 11 a.m.–9 p.m. The posted menu says flavors change daily, so illustrated flavors should not be treated as a promise of today’s case selection.

The menu lists a six-flavor flight for $6.99. Supernovas are posted at $7.50 for medium and $9.50 for large, with mix-in choices such as cookie dough and cookies and cream. Berry and fudge parfaits are listed at $8.99 each. These are posted item prices; confirm the total and any requested extras when ordering.

Other formats include scoops, soft serve, sundaes, shakes and floats. The distinction is useful for planning: a flight, a blended dessert and a traditional scoop order are separate menu choices, rather than interchangeable sizes of the same item.

An optional loyalty-app route

The Cosmic Treats & Sweets App Store listing identifies Planet Mart as the developer and Purvis Brothers, Inc. as the seller. It describes access to deals and a loyalty program, with a free download for compatible Apple devices.

The listing does not establish a specific discount, points conversion or reward for every purchase. Check the current program terms before comparing an app offer with the counter price; a free download is not a guarantee of a particular saving.

What to check before the trip

Use the operator’s current hours and ask about the day’s flavors when a particular choice matters. The earlier newspaper’s flavor counts are a July snapshot, not a fixed October inventory. Likewise, an old opening announcement should not be used as evidence of a promotion still running today.

Our Cosmic Treats business profile links the official menu and this background guide, keeping the current visit information separate from the earlier opening reports.
