S'mores Blossom Cookies

Directions

1. Set oven rack to middle position and preheat oven to 350°F. Line baking sheets with parchment paper or silpats.
2. Whisk together the flour, baking soda, baking powder and salt in a bowl.
3. In the bowl of a stand mixer fitted with the paddle, beat the butter, sugar and 1/2 cup of the graham cracker crumbs on medium-high speed until pale and fluffy, about 3 minutes. Add the egg and vanilla and beat on slow until incorporated. Reduce speed to low, slowly add the flour mixture and mix until just combined.
4. Spread the remaining 1/2 cup graham cracker crumbs in a shallow dish. Use a cookie scoop to portion the dough into about 1 tablespoon balls, roll into balls, then toss in the graham cracker crumbs to coat. Space the dough balls evenly on the prepared baking sheets.
5. Bake 1 sheet at a time until the cookies are just set and beginning to crack on the sides, 10 to 12 minutes. Let cookies cool on the sheet for 5 minutes, then transfer to a wire rack.
6. Adjust oven rack to 10 inches from the broiler and heat the broiler. Place 1 marshmallow half, cut side down, in the center of each cookie. Broil until the marshmallow is a deep golden brown - keep a close eye on them so they don’t burn! Transfer the sheet to a wire rack and immediately place 1 Hershey’s Kiss on each cookie, pressing down lightly to squish the marshmallow out over the cookie. Let cool completely before serving.
