Mary's Mountain Cookies is by far THE best cookie shop there is.. Unlike crumbl, their cookies are made with authenticity and care. It is family owned, by Mitzi and her daughter Kayla, and they incorporate their own twist into the delicious cookie flavours. I cant help but feel like these cookies came from my mommas own kitchen with every bite. Its so hard for me not to eat the whole thing 😋 never too rich, but justtt right! My personal favourite is the Almond Glaze, and...

The customer service is really great, always friendly ladies helping. The cookies are delicious and decorated so cute. They change some of the flavors, adding new ones when seasons change so there is always something new to try. Right now the oatmeal creme pies are my absolute favorite. They are the nostalgic bliss of little debbies, but if mom made them 😂🥰 I love this little shop, I tell everyone about it. Highly recommend to stop for a yummy cookie or 8!!
