These easy, delicious S'Mores Blossom Cookies include all the favorite flavors of the American campfire favorite, S'mores!
For the graham cracker coating, place 1/2 cup graham cracker crumbs and melted butter in a shallow dish. Stir until combined. Set aside.
Add 1/2 cup graham cracker crumbs and stir well to combine.
Sprinkle flour, baking soda, baking powder and salt evenly over the top of the butter mixture and stir until all flour is incorporated.
Working with 1 1/2 tablespoons of dough at a time, roll into 1 1/2-inch balls. Toss dough balls in the prepared graham cracker crumb mixture to coat. Space them evenly on prepared sheets, 12 per sheet.
4. Adjust oven rack 10 inches below broiler element and heat broiler to high. Place one marshmallow half, cut side down, in center of each cookie. Broil cookies, one sheet at a time, until marshmallows are deep golden brown, 30 to 45 seconds, rotating halfway through for even browning, if needed.
Immediately place one Hershey Kiss in the center of each marshmallow, pressing down lightly. Repeat with remaining cookies, marshmallows, and Kisses. Let cookies cool slightly before serving (if you can stand it).
