Mary's Mountain Cookies Avalanches

The Avalanche – our cookie sandwich

Look out, here comes an Avalanche! Here at Mary’s Mountain Cookies, Avalanches have a completely different meaning to it, a definition that will have you running towards it rather than running away! Our Avalanches are made up of two two-ounce cookies, with buttercream frosting sandwiched in between. You can choose from the classic chocolate chip and vanilla frosting, or our Cookies and Cream cookies with Cookies and Cream frosting. It is a customer favorite for all ages with a sweet tooth. Best of all, Avalanches are included in the “Buy 6 Get 2 Free” deal that we run every day!
