Creating S’mores Halloween Treats is a breeze with these step-by-step instructions:

1. Preheat Oven: Begin by preheating your oven to 350°F (175°C).
2. Combine Dry Ingredients: In a large bowl, mix graham cracker crumbs, sugar, and cocoa powder until well combined.
3. Add Butter: Pour the melted butter into the dry mixture and mix until it resembles wet sand.
4. Prepare Baking Dish: Grease an 8×8-inch baking dish and press the graham cracker mixture into the bottom firmly.
5. Layer Chocolate: Sprinkle the semi-sweet chocolate chips evenly over the pressed graham cracker base.
6. Add Marshmallows: Distribute the mini marshmallows over the chocolate layer, covering it completely.
7. Bake: Place the dish in the oven and bake for approximately 10-15 minutes, or until the marshmallows are golden brown and gooey.
8. Cool Slightly: Remove from the oven and allow cooling for 5 minutes. This helps in ensuring the treats hold their shape when cut.
9. Add Candies: While still warm, sprinkle the Halloween-themed candies over the top. Press them gently into the warm marshmallows.
10. Cut and Serve: Once cooled completely, cut into squares or bars. Optionally, you can add edible glitter or sprinkles for an extra festive touch.

By following these straightforward steps, you’ll have delicious S’mores Halloween Treats filled with delightful flavors and fun visual appeal.
