How To Make Halloween Rice Krispie Treats
Prep the Pan: Lightly spray the bottom of a 9×13 baking pan with cooking spray, then line it with parchment paper. The spray helps keep the parchment in place and makes it super easy to lift the treats out when they’re ready to cut.
Melt the Butter: In a large pot, melt the butter over low heat. Keep it nice and slow so everything melts evenly.
Melt the Marshmallows: Set aside 1 ½ cups of marshmallows for later. Add the rest of the marshmallows to the pot with the melted butter, stirring constantly until the mixture is smooth and creamy.
Add Flavor: Remove the pot from heat and stir in the vanilla extract and a pinch of salt for extra flavor.
Mix in the Good Stuff: Now, gently fold in your Rice Krispies cereal along with the reserved marshmallows, pretzel twists, M&M’s, candy corn, and sprinkles. Stir until everything is evenly combined and coated in the marshmallow goodness.
Spread It Out: Transfer the Rice Krispie mixture into the prepared baking pan. Use a rubber spatula to gently spread it into an even layer, but don’t press it down too hard—you want your treats to stay soft and chewy!
Melt the Candy Wafers: Pop your candy wafers into a piping bag and melt them on the low or defrost setting of your microwave. Give the bag a quick massage every 30 seconds to make sure it melts evenly.
Drizzle and Top: Once the candy is fully melted, let it cool for about 5 minutes. Then, snip a small piece off the tip of the bag and drizzle the melted candy over your Rice Krispie treats. Feel free to sprinkle on extra toppings like more M&M’s, pretzels, candy corn, and sprinkles while the drizzle is still wet.
Cool and Cut: Let the treats cool on the counter for 30 minutes to an hour. Once they’ve set, cut them into squares and enjoy!
Variations and Substitutions
Feel free to swap out the regular Rice Krispies for other cereals like Cocoa Krispies, Cocoa Pebbles, or even Corn Flakes if you’re in the mood for something different. They’ll all work great!
When it comes to M&M’s, any color or variety will do the trick. I went with the “Ghoul’s Mix” for a fun Halloween vibe, but use whatever you have on hand.
For the pretzels, you’ve got options! Pretzel twists, sticks, snaps, or waffles all work. You can leave them whole or break them into smaller pieces for extra crunch. They’re great for cutting the sweetness from the candy, but if you’d prefer, you can swap them out for more Rice Krispies and just add an extra ⅛ teaspoon of salt to balance things out.
Storage
These rice krispie treats are best eaten the same day but you can store leftovers in an airtight container on the counter for up to 2 days. I do not recommend refrigerating as it will harden.

Ingredients
1/2 cup 1/2 (1 stick) unsalted butter
14 ounces 14 mini marshmallows, divided
1 tsp 1 pure vanilla extract
1/8 tsp 1/8 salt
7 cups 7 rice krispies cereal
1 cup 1 Halloween M&M’s
1 cup 1 candy corn
3/4 cup 3/4 mini pretzel twists
1/4 cup 1/4 sprinkles
- Optional topping ideas
1/4 cup 1/4 green candy melts, drizzled on
Directions
- Lightly grease the bottom of a 9×13 baking pan with cooking spray and line with parchment paper. The cooking spray will help keep the parchment paper in place when pouring the Rice Krispie mixture in and will also make it easier to remove the treats when they are ready to cut.
- Melt the butter in a large pot over low heat.
- Separate 1 1/2 cups of marshmallows and set it aside to mix in later. Add the rest of the marshmallows to the pot with the melted butter and continue to melt on low heat, stirring constantly until you get a smooth consistency.
- Remove the pot from the heat and then stir in the vanilla extract and salt.
- Fold in the Rice Krispies cereal, mini marshmallows, mini pretzel twists, M&M’s, candy corn, and sprinkles until evenly combined.
- Gently spread the Rice Krispies mixture into an even layer in the baking pan with a rubber spatula. Do not press it in together too firmly otherwise you will end up with hard treats.
- Melt the candy wafers in a piping bag on a low or defrost setting until fully melted. Massage the bag every 30 seconds to ensure even heating.
- Allow to cool for 5 minutes before snipping a small piece of the tip and drizzling over the prepared Rice Krispie treats. Immediately top with additional toppings such as more M&M’s, pretzels, candy corn, and sprinkles if desired.
- Allow it to cool on the counter for 30 minutes to 1 hour before cutting into squares. Enjoy!
Notes
- You can use another cereal such as cocoa krispies, cocoa pebbles, or even corn flakes instead of regular rice krispies if desired
- Any color and variety of M&M’s will work. I opted for their “Ghoul’s Mix Milk Chocolate M&M’s”
- You can use pretzel twists, sticks, snaps, crisps, waffles, etc. Keep the pretzels whole or break them into smaller pieces
- The pretzels help to balance out the sweetness from the candy but you can opt to replace it with the same amount of rice krispies cereal and just add another ⅛ teaspoon of salt if desired.
