Introduction

Indulge in the nostalgic flavors of campfire s’mores with this Single Serve S’mores Cookie. Perfectly gooey and loaded with chocolate, marshmallows, and graham cracker crumbs, it’s a delightful treat you can whip up in minutes.

A round cookie base with a rough, crumbly texture and light brown color forms the bottom layer. On top of the cookie is a thick layer of melted dark chocolate spreading unevenly, giving it a glossy and rich look. The next layer is a cluster of large white marshmallows, some browned and toasted on top, evenly placed covering most of the cookie surface. Drizzled over the marshmallows and chocolate is a thin stream of dark chocolate sauce, adding a shiny contrast. Small crunchy crumbs are sprinkled over the whole dessert, enhancing the texture. The dessert sits on a white speckled plate, placed on a wooden surface, with a blurred glass of milk and scattered mini marshmallows in the background. Photo taken with an iphone --ar 4:5 --v 7

Step 5: Scoop the dough onto the prepared baking sheet, shaping it into a single large cookie.

Tips & Variations

For extra flavor, sprinkle additional chocolate chips or graham cracker crumbs on top before baking.
Make it vegan by substituting butter with a vegan alternative and using a flax egg.
Use coconut oil instead of butter for a different flavor profile.
Substitute all-purpose flour with gluten-free flour to make the cookie gluten-free.
Customize by adding nuts or different types of chocolate.
For a quick fix, cook the dough in a microwave-safe mug for 40-60 seconds.

Storage

Store any leftover cookie in an airtight container at room temperature for 1-2 days. Reheat gently in the microwave or enjoy at room temperature for a chewier texture.
