Our ice cream just got better and healthier!

Today marks 8 years since we began service at Mullen's Dairy Bar. We wanted to thank all our dedicated team members—past and present—as well as our loyal customers who have been part of the Mullen's Dairy Bar story.

We'd like to take this occasion to announce a big change to our homemade ice cream that is making it creamier and healthier! We developed a new, all-natural 14% butterfat mix with our long term local partner Galloway Company.

So what does that mean? It means that Mullen's Dairy Bar is now a "super premium" ice cream—but most importantly our ice cream no longer contains corn syrup and carrageenan!

When we announced the transition away from artificial dyes last fall—we received considerable feedback about both corn syrup and carrageenan. We shared we were on a journey to get to an all-natural ice cream that families can enjoy. We are proud to announce that we are now there.

Tonya and her team have been churning this new ice cream for a couple weeks and we are so excited to share it with all of you!

Come see us for a scoop or two this weekend—all locations are open for the season! ✌🏻❤️🍦
