Wow! My daughter and I loved everything we got! The cookies were large and had a great texture to them! The Turtle Infused Cookie was my favorite bc it had a chocolate drizzle on top that really made it pop- but my daughter loved the Oreo ! The S'more one was missing the chocolate drizzle that is on the top of it on the pic but it was still good. I would suggest trying Mary's!

This was the first time I ordered from Mary's Mountain cookies and all I can say is wow!! The cookies were so fresh and very big! I especially loved the Frosted Sugar, the icing was delicious! Reminded me of my childhood when my mom would bake sugar cookies during the holidays and I'd help put the frosting on them. I will definitely be ordering again from Mary's. I think I've just found my new favorite cookie place.

5oz Snickerdoodle is on point! 5oz Chocolate Chip Cookie was good but needs more chocolate chips to make up for the size. The 2oz Oreo Crunch is different and just ok. Probably would be better with frosting

We have been wanting to try this cookie place for a awhile. I am mad we waited so long. We are not fans of Crumbl at all and Mary's Mountain Cookies blew us away. Absolutely amazing and delicous. We will be back.
