1 ½cups (170 grams)graham cracker crumbsabout 10 full graham crackers, turned to flour in a food processor and sifted for large chunks
1teaspoonbaking soda
1teaspoonkosher salt
2 ¼cups (270 grams)all-purpose flour
1(3-ounce container)marshmallow bits*
2cupsmixed milk and semi-sweet chocolate chunks
Topping:
1cupmini marshmallows
Instructions
Preheat the oven to 350°F. Line a baking sheet with parchment paper.
In the bowl of a stand mixer fitted with the paddle attachment, mix the butter and sugar on medium speed for 2 minutes until light and fluffy. Turn the speed down to medium low and add the eggs one at a time, then the vanilla. Scrape the sides of the bowl as necessary, ensuring the mixture is cohesive.
With the mixer on medium-low speed, add the graham cracker crumbs, baking soda, and salt, mixing until incorporated.
Turn the speed to low and stir in the flour until just combined. Stir in the marshmallow bits and chopped milk chocolate until evenly incorporated.
Using a standard (1.5-ounce) cookie scoop, drop balls of dough about 2 inches apart onto the baking sheet.
Bake the cookies for 5-6 minutes, remove the pan from the oven, and press 3 mini marshmallows carefully on the tops of the cookies. Return to the oven and continue baking for 4-6 minutes, until the marshmallows puff up and turn golden. The cookie edges should be lightly golden on the edges and tops as well.
Allow the cookies to cool on the baking sheet for 5 minutes, then serve warm or transfer to a wire rack to cool completely.
These can be stored in an airtight container at room temperature for up to 3 days.
Notes
If you cannot find marshmallow bits (they should be at Target or a chain supermarket) and you don't want to go to the trouble of making your own (I don't blame you), it's okay to leave them out.
