Apparently, cookies-and-cream ice cream needed a brownie situation underneath it. Oberweis and Killer Brownie have teamed up on a Kitchen Sink Sundae, and this is not a one-topping operation.

The limited-time dessert is available at Oberweis Ice Cream and Dairy Stores throughout September 2026, while supplies last. There’s also a Wednesday discount to know about before you plan your dessert run.

What’s in the Kitchen Sink Sundae?

It starts with a warm Killer Brownie Kitchen Sink Brownie: a chocolate-brownie and blondie combination with chocolate chips, sprinkles and M&M’s. Oberweis adds its Cookies & Cream ice cream, hot fudge, whipped cream, more sprinkles and a cherry.

So, yes, there’s a brownie layer, a blondie layer and cookies in the ice cream. Choosing just one dessert component was apparently not on the agenda.

Wednesdays get you $1 off

The brands’ September 8 announcement says guests get $1 off the Kitchen Sink Sundae every Wednesday in September. The remaining Wednesday dates after September 17 are September 23 and September 30.

The release does not give a standard sundae price. Check your shop for pricing and availability, especially if you’re making a special trip; the collaboration is limited-time and while supplies last.

Where to find it

This is an Oberweis Ice Cream and Dairy Store dessert, not a promise that the packaged brownie aisle has a ready-made sundae waiting for you. Use Oberweis’s official site to find a location and check store details.

Brownie people and cookies-and-cream people can call a temporary truce. There’s room for both in this bowl.
