1 cup of mini marshmallows or large marshmallows cut up
Preheat oven to 375 degrees.
In the bowl of a mixer, cream butter and then add both sugars. Once mixed, add in egg and vanilla extract.
In a separate bowl, combine flour, graham cracker crumbs, salt, and baking soda.
Add the dry mix into the wet mixture, scraping down the sides to make sure everything is incorporated.
Mix in chocolate chips (not the Hershey's squares yet.)
Scoop the cookie dough into 24 balls and spread out on two cookie sheets lined with a silicone baking mat or parchment paper.
Bake one tray at a time for 8 minutes, take out of the oven, closing the oven door so you do not lose heat. Press marshmallows and Hershey's squares into the top of the cookies (I did 1-2 squares and then 3-4 marshmallows in each cookies). Put tray back in the oven and bake for an additional 3-4 minutes. Repeat for second tray.
Let cookies cool for 5-10 minutes and then move to cooling tray. Store in an airtight container.
