Crumbl Review: Oatmeal Marshmallow Cookie
This one is built around a really solid concept — taking a classic oatmeal cookie and softening it with marshmallow. It’s not trying to be flashy or overly complex, which actually works in its favour because oatmeal cookies rely a lot on texture and balance rather than bold flavour.
The base of the cookie is exactly what you’d want from an oatmeal cookie. It’s soft, slightly chewy, and has that subtle grainy texture from the oats that gives it a bit more structure than a standard cookie. It’s not dry, and it doesn’t crumble apart — it holds together really well while still feeling light.
Flavour-wise, it leans warm and slightly sweet. You get that mild brown sugar and oat flavour, but it’s not overly spiced or heavy. It’s more of a clean, comforting flavour rather than something bold.
The marshmallow is what changes the whole experience. It adds a soft, slightly stretchy texture and a light sweetness that blends into the cookie rather than sitting on top of it. It doesn’t overpower the oatmeal — it just softens it and makes it feel more like a dessert.
Texture is where this cookie really works. You’ve got the chew from the oats combined with the smooth, almost melted feel of the marshmallow, which keeps it from being too one-note.
What I like about this one is how balanced it feels. It’s not too sweet, not too rich, and not too heavy. It’s just a really easy cookie to eat.
Final Verdict:
A soft, balanced cookie that leans into comfort flavours. Simple, but done really well.
