The s'more has a documented birthday. August 1927, when a recipe for "Some Mores" appeared in a Girl Scout handbook called Tramping and Trailing with the Girl Scouts. The name tells you everything about the original experience: you'd finish one and immediately want some more. This cookie captures that same compulsion.

The trick is building graham flavor into the dough itself. Most recipes just stick a graham cracker piece inside and call it done. That's lazy. Grinding crackers into the flour gives you that honeyed, toasty flavor in every bite, not just where you happen to hit a chunk. The stuffing stays simple: a square of good chocolate pressed against a marshmallow, then sealed inside dough and frozen before baking.

Freezing matters. Without it, your marshmallow melts out the bottom and your chocolate runs before the cookie sets. Twenty minutes in the freezer creates a thermal buffer. The outside bakes golden while the center stays protected just long enough to turn gooey without escaping. Pull these from the oven when they look slightly underdone. They'll firm up as they cool, and the center will stay soft for hours.

I've brought these to more potlucks than I can count. They disappear first, every time. The secret isn't really a secret: Americans have been chasing that campfire feeling since childhood. This cookie delivers it without the smoke in your eyes.

The technique, the tradition, and the story behind every dish.

Equipment Needed

  • Stand mixer with paddle attachment
  • Food processor (for grinding crackers)
  • #16 cookie scoop or tablespoon measure
  • Rimmed baking sheets
  • Parchment paper
  • Wire cooling rack

Instructions

  1. 1

    Make graham flour blend

    Whisk together the all-purpose flour, graham cracker crumbs, baking soda, salt, and cinnamon in a medium bowl. The crumbs should be powder-fine. If yours are coarse, pulse them in a food processor until they resemble sand. This graham flour is where your cookie gets its soul.

    Use whole graham crackers you grind yourself for the freshest flavor. About 8 full cracker sheets yield 1 cup of crumbs.
  2. 2

    Cream butter and sugars

    Beat the softened butter with both sugars in a stand mixer fitted with the paddle attachment on medium-high speed. Go for a full three minutes. The mixture should turn pale, fluffy, and noticeably lighter in color. Scrape down the bowl once halfway through. This aeration gives your cookies their chewy centers.

  3. 3

    Add eggs and vanilla

    Add the eggs one at a time, beating for 30 seconds after each addition. Pour in the vanilla and mix until combined. The batter may look slightly curdled at this point. That's fine. It comes together when the dry ingredients go in.

  4. 4

    Form the dough

    Reduce mixer speed to low and add the flour mixture in two additions, mixing just until the last streak of flour disappears. Fold in the chocolate chips by hand with a sturdy spatula. The dough will be thick, almost like soft clay. Resist the urge to add more flour.

  5. 5

    Assemble stuffed centers

    Press one chocolate square firmly against a marshmallow, slightly embedding it. These become your cookie centers. Using a #16 cookie scoop or about 3 tablespoons of dough, flatten a portion in your palm. Place the marshmallow-chocolate combo in the center with the chocolate facing down. Wrap the dough around it completely, pinching seams closed and rolling into a smooth ball. The seal must be tight. Any gaps and your marshmallow escapes during baking.

    Slightly wet hands prevent the dough from sticking as you work. Keep a small bowl of water nearby.
  6. 6

    Freeze the cookies

    Arrange stuffed dough balls on a parchment-lined baking sheet, spacing them two inches apart. Freeze for at least 20 minutes, or up to 30. This step is not optional. The cold core buys you time in the oven, letting the outside set before the inside turns to lava and bursts through.

  7. 7

    Preheat and prepare

    Position a rack in the center of your oven and heat to 350°F (175°C). Line two fresh baking sheets with parchment paper. If you only have one sheet, you'll bake in batches, keeping remaining dough balls frozen until ready.

  8. 8

    Bake until golden

    Transfer frozen dough balls to prepared sheets, leaving three inches between each. They spread significantly. Bake 12 to 14 minutes, rotating the pan halfway through. The cookies are done when edges turn golden brown but centers still look pale and slightly puffy. They'll appear underdone. Trust this. The centers firm up as they cool, trapping that gooey pocket inside.

    Watch for the first hint of golden color around the edges. That's your cue to start checking every minute. Overbaking turns your molten center into a chewy lump.
  9. 9

    Cool and serve

    Let cookies rest on the baking sheet for a full 5 minutes. They're fragile when hot and the centers need time to set up slightly. Transfer to a wire rack using a thin spatula. Serve warm for the most dramatic marshmallow pull, or at room temperature where they're easier to transport. Break one open before serving. The sight of that stretchy marshmallow center sells these better than any description.

Chef Tips

  • Quality chocolate matters here. Use a bar you'd happily eat on its own. Ghirardelli or Lindt work well. Baking chips for the dough are fine, but the center square should be the good stuff.
  • These cookies spread flat if your butter is too soft. It should hold a thumbprint but not look greasy or shiny. If your kitchen runs warm, refrigerate the butter briefly before using.
  • For an extra campfire touch, lightly toast the tops of the cookies under the broiler for 30 seconds after baking. Watch constantly. The line between toasted and burned is measured in seconds.
  • Store baked cookies in an airtight container at room temperature for up to 3 days. The marshmallow center stays soft. Reheat briefly in a 300°F oven to restore the gooey pull.

Advance Preparation

  • Assembled unbaked dough balls freeze beautifully for up to 2 months. Freeze solid on a sheet pan, then transfer to a zip-top freezer bag. Bake directly from frozen, adding 2-3 minutes to the baking time.
  • The dough can be made and refrigerated up to 3 days ahead. Let it soften at room temperature for 15 minutes before scooping and stuffing.
  • Baked cookies can be frozen for up to 1 month. Thaw at room temperature and warm briefly in a low oven to revive the gooey center.
