S'mores Cookies with Graham Crackers and Marshmallows

Soft, chewy cookies that capture all the nostalgic flavors of campfire s'mores in a handheld treat. These cookies combine chunks of graham crackers, melted chocolate pieces, and gooey mini marshmallows in a tender butter cookie base. Perfect for summer gatherings, bake sales, or whenever you're craving that classic s'mores combination without the campfire. The key is chilling the dough to prevent spreading and carefully sealing marshmallows inside to avoid melting onto the baking sheet.

Full guide →FAQ
Can I make these without chilling the dough?
Chilling is essential to prevent excessive spreading. Without it, cookies will be thin and may lose their shape and texture.
What if I don't have butter extract?
You can omit butter extract or substitute with additional vanilla extract, though the flavor will be slightly different.
How long do these cookies stay fresh?
Store in an airtight container for up to 3 days at room temperature, or freeze for up to 3 months for longer storage.
