I ranked every concrete from Andy’s Frozen Custard. From treats with whole pie slices to Oreo chunks, they’re definitely not created equal.

• I compared seven concretes from the Midwest-based chain Andy’s Frozen Custard.
• I wasn’t a huge fan of the triple-chocolate option because it was a little too rich for me.
• The nutty waffle crunch and BootDaddy concretes were my favorites.

I grew up on the West Coast and first discovered frozen custard when I moved to the Chicago suburbs for college. Since then, I’ve been a fan of the Midwestern staple, which is made with egg yolks and usually has a smoother, thicker texture than ice cream.

In recent years, however, the frozen dessert’s popularity has grown beyond the Midwest, partially due to the US’s largest frozen-custard-only chain, Andy’s Frozen Custard.

The Missouri-based chain, which has over 150 locations across 15 states, is famous for its concretes — frozen vanilla or chocolate custard blended with other ingredients like fruit or candy.

Recently, I headed to my local Andy’s to try all the concretes available and see which were best. Here’s how the frozen desserts stacked up, from worst to best.
