Method
Make the cookies
- Heat the oven to 350°F with a rack in the center.
- Lightly grease an 18x13-inch broiler-safe metal baking sheet with the oil.
- In a medium bowl, whisk the melted butter, brown sugar, granulated sugar, pumpkin puree, egg yolk, and vanilla until smooth.
- In a separate bowl, whisk together the flour, graham cracker crumbs, baking soda, pumpkin pie spice, and salt.
- Fold the dry ingredients into the pumpkin mixture just until no dry streaks remain.
- Fold in the chocolate chips.
- Cover and refrigerate the dough for 30 minutes.
- Divide the dough into 12 equal portions, about 1/4 cup each, and arrange them at least 3 inches apart on the prepared baking sheet.
- Bake for 13–15 minutes, until the edges are set and the centers look soft.
Toast the marshmallows
- Set the oven to high broil and position the rack about 6 inches below the broiler element.
- Press one marshmallow half, cut side up, onto each cookie.
- Broil for 30–60 seconds, watching continuously, until the marshmallows are puffed and golden.
Cool the cookies
- Let the cookies cool on the baking sheet for 10 minutes.
- Transfer them to a wire rack.
Notes
For evenly toasted tops, watch the cookies continuously while broiling. Store in an airtight container in the refrigerator for up to 4 days; freeze without marshmallow topping for up to 2 months. For a dairy-free variation, use dairy-free butter and chocolate chips and check that the marshmallows are dairy-free.
