What Is the Crumbl Oatmeal Marshmallow Cookie?
The Crumbl Oatmeal Marshmallow Cookie is a gourmet bakery cookie built around a soft and chewy oatmeal base. It is flavored with gentle spices and natural sweetness, then topped with a generous layer of marshmallow cream cheese frosting.
Unlike basic oatmeal cookies, this version includes hints of molasses and vanilla, which deepen the flavor without making it heavy. The frosting adds a fluffy, cloud-like finish that melts smoothly with every bite. Together, these elements create a cookie that feels rich yet comforting.
Although some testing flavors come with extra charges, this cookie is treated as a standard Crumbl cookie, meaning there is usually no upcharge when it appears on the weekly menu.
Flavor Profile and Taste Experience
A Balanced and Comforting Flavor
The first bite delivers a soft and chewy oatmeal texture. Immediately after, the warm spices come through, followed by light sweetness from molasses and vanilla. Then, the marshmallow cream cheese frosting adds smoothness and mild tang, preventing the cookie from tasting overly sweet.
Overall, the flavor is balanced rather than intense. This makes it easy to enjoy an entire cookie without feeling overwhelmed.
Texture You Can Expect
- Soft and chewy oatmeal base
- Creamy and airy frosting
- Slightly dense center for a bakery-style bite
This contrast in textures is one reason customers describe it as “comforting but indulgent.”
