Mary's Mountain Cookies in South Fort Collins

Love love love Mary’s Mountain Cookies! Every time I come to this location, the staff are so friendly, helpful, and available (and also very patient as I take forever to decide). There’s so many delicious cookies to choose from, you can’t go wrong! My personal favorite is the frosted Oreo cookie, so yummy!

I was craving sweets and this was the perfect spot! Being out of town, I was happy to see such great selection and they tasted delicious! I’m definitely making another visit when I’m back in town ⭐️

The best customer service and workers! I went last night around 7:30 while door dashing. The workers that helped me while choosing which cookie flavors I liked were the kindest people ever. Used to go to the old town location, but will from now on go to this location because they are what customer service should be. PS. The s’more’s cookie is to die for.

wonderful service and delicious cookies.

Everyone here is really nice every time I go in but tonight I was walking home from work and smelled the cookies and had to stop in. So, I got a red velvet cookie (which was amazing) and after a couple bites, walking home, I dropped it in goose poop :( so my mom stopped in an hour later to get another to replace it and told the girls working about it and they were so lovely and kind and offered one to make up for my bad luck and JUST BECAUSE OF THIS I will now make this a weekly stop on my way home because that is the sweetest thing ever thank you guys so much <3

Best cookies ever!

I've been going to this location for about 15 years. It has a new owner as of two months ago, and things are really going downhill. They changed the names of all of the cookies to make them 'cutesy' but it's really just annoying and confusing. They no longer have 'avalanche' (two cookies sandwiched around frosting) cookies in the display case, instead they moved them to the freezer. So they're hard as a rock now, which is the biggest issue with all of the cookies. They all used to be big and soft and chewy and delicious. Now they're flat and hard. I have to put them on the microwave when I get home.

Extremely displeased with what's happening, it's been a family ritual to go there every Friday with my family for years, so this is really sad to see.

Omg. The BEST cookies I have ever eaten. EVER. And the people that work there.... AWESOME, friendly,.

Amazing cookies, and very friendly staff. I needed to pick out a few cookies as gifts, the staff was very patient and helped me make my selection. The cookies were amazing, and my only regret is that I didn't buy more. Highly recommended!

My granddaughter loves Mary's Mountain Cookies!! There is a large assortment of options, plus big cookies and smaller cookies. She loves their frosted sugar cookie and I enjoy the s'mores cookie.

There was such a great variety of cookies at Mary's, but this s'mores one really spoke to me. The soft, pillow marshmallow, chocolate chunks and integrated graham crackers all made for a delicious eating experience. The cookie is huge too! And a at a decent price. Good service, nice little spot to hang out.

I love coming to this cookie shop! It’s seriously one of my favorites! The employees are all extremely friendly and knowledgeable about their products. I’m writing today because my experience was so positive! The young man and two women are an amazing dynamic!

Very good cookies!! The ice cream is good too!!

Such a sweet staff! Thank you 🍀

Give me all the cookies! They have so many options, and it's so hard to choose because everything looks delicious. Their cookies are giant, too. I highly recommend their smores cookies and the M&M Avalanche. What a charming little cookie shop.
