Preparation Steps

• Preheat oven to 375°F (190°C). Line baking sheets with parchment paper.
• In a large bowl, cream together the softened butter, granulated sugar, and brown sugar until light and fluffy.
• Beat in the eggs one at a time, then stir in the vanilla extract.
• In a separate bowl, whisk together the flour, baking soda, and salt.
• Gradually add the dry ingredients to the wet ingredients, mixing until just combined. Do not overmix.
• Stir in the chocolate chips and graham cracker crumbs.
• Drop rounded tablespoons of dough onto the prepared baking sheets. Gently press a few mini marshmallows into the top of each cookie dough ball.
• Bake for 10-12 minutes, or until the edges are golden brown and the centers are still slightly soft.
• If desired, you can briefly broil the cookies for 30-60 seconds to toast the marshmallows. Watch carefully to prevent burning.
• Let the cookies cool on the baking sheets for a few minutes before transferring them to a wire rack to cool completely.
