Add to a baking sheet: Spread the mixture into a parchment paper lined baking sheet.
Add the drizzle on top: Melt candy wafers in a piping bag and drizzle over the top of the Rice Krispie treats.
Add more toppings if liked: You can add more toppings if liked, and then just let the Halloween Rice Krispie treats set. When firm, you can slice them and serve.
Substitutions and Variations
Different candies: Any colors of M&Ms would work or you could use different candies like Skittles, white or milk chocolate chips, or butterscotch chips.
Another pretzel shape: Use pretzel twists, snaps, waffles, sticks, or any shape. You can either break them up or add them whole. If you don’t like pretzels, use extra Rice Krispie cereal and a pinch of salt.
A different cereal: Cocoa Pebbles, Cocoa Krispies or Cornflakes would work in place of the Rice Krispies.
Serving Suggestions
Savory scary snacks: A charcoal black crust pizza or jack-o-lantern stuffed peppers are great Halloween options.
Sweet spooky treats: Pair your Frankenstein Rice Krispie treats with chocolate frogs and Snickers mummies.
Devilish drinks: You can’t go wrong with vampire kiss jello shots or Halloween ice cream floats.
How to Store Rice Krispie Treats
Store: These are best served the day they’re made but you can keep leftovers in an airtight container on the counter for up to 2 days. Don’t refrigerate a Rice Krispie treat – they’ll become too hard when chilled.
Freeze: They don’t freeze well.
Top Tips
Don’t skip the nonstick cooking spray: It helps hold the parchment paper in place when you add the Rice Krispies mixture and also when you’re ready to slice.
Press the Rice Krispie mixture in gently: Don’t press down too hard because this would make the treats hard.
No piping bag? Use a Ziploc bag instead.
