Introduction

This Single Serve S’mores Cookie is a perfect quick treat for satisfying your sweet tooth without making a whole batch. It combines the classic flavors of chocolate, marshmallow, and graham crackers into one gooey, delicious cookie just for you.

A round cookie base with a rough, golden-brown texture forms the bottom layer, topped with a thick layer of melted dark chocolate that shines slightly. On top of the chocolate, there is a layer of large toasted marshmallows, white with golden brown spots, arranged close together covering most of the surface. Drizzles of dark chocolate sauce run over the marshmallows, and small crumbs of roasted crumbs are scattered on top, adding a crunchy texture. The cookie is placed on a white speckled plate set on a wooden surface with some small marshmallows scattered around, and a glass of milk is seen blurred in the background. photo taken with an iphone --ar 4:5 --v 7

How to Serve

A large round cookie forms the base layer, golden brown with a crumbly texture and visible chocolate chunks mixed in. On top of this cookie, there is a layer of melted dark chocolate spread thickly, slightly glossy and oozing around the edges. The top layer consists of puffy marshmallows toasted to a light golden brown on their tops, arranged close together covering the chocolate completely. Drizzled over the marshmallows is a thin runny chocolate sauce, dark and shiny. Light brown crumbs are sprinkled on top of the marshmallows and chocolate drizzle, adding a crumbly texture. The dessert is placed on a white plate with small black speckles, sitting on a white marbled textured surface. In the background, a clear glass filled with white milk is visible with small marshmallows scattered around. photo taken with an iphone --ar 4:5 --v 7
