Cosmic Ice Cream and Trill Burgers teamed up on a banana pudding milkshake as Houston's summer heat pushed more customers toward cold treats and quick neighborhood stops. The collaboration surfaced July 8, 2026, and tied into the National Ice Cream Day stretch, giving two local brands a shared promotion built around foot traffic and social-media reach.
For Cosmic, the partnership also puts a newer Bellaire shop in the spotlight. Camille and Julian Haynes opened the company’s first location in Webster and Clear Lake in February 2021, followed by Spring Branch in 2023 and Pearland in 2024. The Bellaire store opened this spring at 5400 Bissonnet St., Suite 12, in the Bellaire Triangle Shopping Center, a roughly 1,164-square-foot space that operates daily from noon to 10 p.m.
The milkshake fits naturally with Cosmic’s menu. The company already sells a Banana Pudding flavor built from roasted banana ice cream, Nilla wafer pieces and Cool Whip swirl, making the collaboration feel less like a random stunt and more like an extension of what the shop already does well. Cosmic makes its ice cream in-house and builds flavors from the owners’ travels, family recipes, childhood memories and customer suggestions, a formula that has helped the brand move from one storefront to four across the region in just a few years.
Trill Burgers brings a different kind of local recognition. Bun B’s burger chain centers its sandwiches on two 44 Farms Texas beef patties, caramelized onions, pickles and Trill Sauce on a potato roll bun, a straightforward Texas product that has grown from a pop-up idea into a more established Houston restaurant name. The brand has also leaned into dessert tie-ins before, including Trill Shakes made with Cosmic HTX ice cream in Missouri City, suggesting this latest pairing is part of a broader habit of cross-brand marketing rather than a one-off novelty.
That matters in Harris County because these collaborations now serve a clear business purpose. Instead of relying only on a new store opening or a standard menu update, Cosmic and Trill Burgers are using a limited-run flavor to draw repeat visits, reinforce local identity and keep both brands in the conversation during the slow, scorching stretch of summer.
