Spooky Halloween Rice Krispie Treats Recipe
Introduction
These Spooky Halloween Rice Krispie Treats are a fun and festive twist on a classic favorite. Easy to make and decorated with eerie green and black candy melts, they’re perfect for parties or a seasonal treat. Kids will love helping with the decorating too!

Ingredients
- 6 cups Rice Krispie cereal
- One 10oz bag mini marshmallows
- 4 tbsp unsalted butter
- 10oz green candy melts
- 3oz black candy melts
- Royal icing eyes
- Black jimmies sprinkles
Instructions
- Step 1: Line a 9×13-inch baking pan with parchment paper, leaving an overhang, or grease it generously to prevent sticking.
- Step 2: In a large pot, melt 4 tablespoons of unsalted butter over low heat. Add the mini marshmallows and stir constantly until the mixture is completely smooth and gooey.
- Step 3: Remove the pot from heat, then quickly add the Rice Krispie cereal. Stir well until all the cereal is evenly coated with the marshmallow mixture.
- Step 4: Press the mixture gently but firmly into the prepared pan. Use buttered hands, cooking spray, or a piece of parchment paper to prevent sticking, and avoid over-compressing the treats.
- Step 5: Let the treats cool completely at room temperature for 30-60 minutes, or refrigerate for 15-20 minutes until set. Lift the block using the parchment overhang and cut into desired shapes. Lightly grease your knife or cutters to prevent sticking.
- Step 6: Melt the green and black candy melts separately according to package instructions. Use the melted candy to drizzle, create patterns, or attach royal icing eyes and black jimmies sprinkles to decorate.
- Step 7: Allow the decorations to fully set and harden at room temperature or in the refrigerator for 10-15 minutes before serving.
Tips & Variations
- Use Halloween-themed cookie cutters like pumpkins, bats, or ghosts for extra festive shapes.
- If candy melts are too thick, stir in a small amount of vegetable oil to achieve a smoother drizzle.
- Substitute colored sprinkles or edible glitter to customize your spooky look.
- For a twist, add a handful of candy corn or Halloween candies into the cereal mixture before pressing into the pan.
Storage
Store leftover treats in an airtight container at room temperature for up to 3 days. Place parchment paper between layers to keep decorations intact. If decorations soften, chill briefly before serving to firm them up again.

FAQs
Can I make these treats without candy melts?
Yes, you can skip the candy melts and decorate with just royal icing or sprinkles, or enjoy the plain Rice Krispie treats as they are. Candy melts add color and design but aren’t essential.
How can I keep the treats from sticking to the pan?
Using parchment paper with an overhang or generously greasing the pan will help release the treats easily. Also, using buttered hands or parchment when pressing the mixture prevents sticking during preparation.

- 10 oz green candy melts
- 3 oz black candy melts
- Royal icing eyes
- Black jimmies sprinkles
Instructions
- Prepare Pan: Line a 9×13-inch baking pan with parchment paper, leaving an overhang, or grease it generously to prevent sticking of the treats later on.

Use the parchment overhang to lift the block from the pan, then cut into squares, rectangles, or use Halloween-themed cookie cutters. Lightly grease your knife or cutters to prevent sticking.
