Halloween Rice Krispie Treats

Halloween Rice Krispie decorating has become one of our favorite October traditions. I set out the icing, candy eyes, and sprinkles, and my eight kids create their own monsters and mummies. After 20 years of baking for my family, I know some of the best Halloween treats are the ones the kids help make.

Why This Recipe Works

• Quick and Easy – They are the cutest and can be made in minutes making them the perfect last minute Halloween treat. 
• Simple Ingredients – Start with pre-made rice crispy treats from your local grocery store. Then add your favorite decorations for a crowd pleasing Halloween Rice Crispy Treats.
• Perfect Party Treat – If you love to plan a Halloween Party this would be perfect activity for the kids to do.

Ingredients

• Pre-made original Rice Krispie Treats — 16 standard store-bought treats give you the perfect amount for 8 monsters and 8 mummies. Original flavor works best as the neutral base for the decorations. Mini treats work for bite-sized versions. Homemade rice krispie treats work equally well.
• Candy eyes — 32 eyes gives you 2 per treat. These are available in the baking aisle of most grocery stores or at any craft store near Halloween. Mini candy eyes give a more delicate look and jumbo candy eyes give a funnier more cartoonish result — both work beautifully
• Green pre-made decorating icing — used for the monster faces. Store-bought tubes give you the most control for spreading. If using white icing tint with green gel food coloring for a vibrant Frankenstein green
• White pre-made decorating icing — used for the mummy wrapping lines. The white color against the tan rice krispie treat gives you the classic mummy bandage appearance
• Black writing gel — used to pipe the monster mouth and add detail to both designs. Writing gel is thinner and more precise than regular icing — it flows through a small tip perfectly for clean lines and details
• Black sugar sprinkles — scattered over the green monster icing to create the Frankenstein hair detail. Black sanding sugar or any dark sprinkle works as a substitute

Carrie’s Tip: You do not need a piping bag for this — a regular zip-top sandwich bag works just as well and is what I use every single time. Spoon the icing into the corner of the bag press all the air out and seal it tightly. Then snip the very tip of the corner with scissors — start with the smallest cut possible and make it bigger if needed. This gives you total control over the icing lines and means no special equipment is required for the kids to decorate their own.

How to Make Mummy Rice Krispie Treats

Step 1 – On the remaining Rice Krispie treats, put the eyes on the middle. Use a little bit of icing to glue on some eyes. You can even use chocolate chips for eyes if you do not have any candy eyes.

Step 2 – Then, I put some icing in a sandwich bag. I pressed all the icing towards the corner and I cut the corner to make a homemade piping bag. Then I “piped” the lines on the Rice Krispies Treats to look like Mummies.

Step 3 – Serve at your next Halloween Party for a fun and festive treat.

Tips for Success

• Set up a decorating station first. Lay out all the icing candy eyes sprinkles and zip-top bags before you open a single treat — once you start decorating you want everything within reach
• Work one design at a time. Complete all the monsters before starting the mummies so the icing does not set before the decorations go on
• Less icing is more. A thin even layer of green icing on the monster gives a cleaner result than a thick glob — spread thinly and evenly for the best appearance
• Snip the smallest possible hole. Start with the tiniest snip on the zip-top bag corner — you can always make it bigger but you cannot make it smaller. A small hole gives you far more control over the icing lines
• Let them dry completely before stacking. Always let the icing set for at least 15–20 minutes before stacking or packaging — wet icing smears and the candy eyes can shift

Make Ahead and Storage Instructions

Make Ahead

• Decorate up to 2–3 days ahead and store in a single layer in an airtight container at room temperature. The icing sets firmly overnight making them actually easier to stack and transport by the next day

Storage

• Store in an airtight container at room temperature for up to 4 days — separate layers with parchment paper to prevent the decorated surfaces from sticking together

Packaging for Parties

• Wrap individual treats in small cellophane bags tied with an orange or black ribbon for the most impressive Halloween party favor presentation — these look like they came from a specialty bakery and cost less than $1 each

Homemade Option

• Make homemade rice krispie treats using butter mini marshmallows and rice krispie cereal — line the pan with parchment paper cut into rectangles and decorate the same way. Homemade treats are slightly softer than store-bought and give a more rustic result
