Ingredients
Method
- **Brown.** Melt butter in a saucepan over medium heat 5 minutes until amber and nutty. Cool 15 minutes.
- **Mix.** Whisk cooled brown butter with brown sugar and granulated sugar 2 minutes. Add eggs and vanilla, whisk smooth.
- **Combine.** Stir in flour, baking soda, salt, and chocolate chips until just combined.
- **Stuff.** Scoop 1/4 cup dough, flatten in your hand. Place 1 tbsp marshmallow fluff, a graham cracker piece, and a chocolate chunk in the center. Top with another 1/4 cup dough and pinch seams closed completely.
- **Chill.** Place stuffed cookies on a parchment lined sheet pan and chill 30 minutes.
- **Bake.** Preheat oven to 375F. Bake chilled cookies 14 to 16 minutes until edges are set and tops golden.
- **Serve.** Cool 5 minutes on the pan and serve warm so the marshmallow centers are still gooey and stretchy.
Notes
Brown the butter for a deeper flavor that mimics campfire roasted marshmallows. Use marshmallow fluff, not whole marshmallows. Whole marshmallows shrink and harden in the oven. Seal the dough seam fully closed by pinching with wet fingers.
