These are some of the best cookies me and my family have ever had. They are awesome. You will not be disappointed and you’ll be going back for more. I would recommend as gifts, events, and just for snacking. These are great.

This place has some amazing cookies. Gourmet and worth the price (and calories). My favorite is the s’mores cookie and a pecan turtle one. So far no other place has beat their cookie quality. Mary's is the best!

Wow... I mean... Cookie Crumbl has NOTHING on these because they actually sell real cookies. We bought 6 and got 2 free. You can bye editable cookie dough, gluten free versions, ice cream AND.... you can buy the premade dough to bake at home! Pairs great with Baron's Creek Wine...
