How to Make Halloween Rice Krispie Treats

Spray 9 x 13 pan with non-stick spray and set aside.

Melt 3 tbsp butter in a large microwave safe bowl.

Pour 1 (10 oz) bag of marshmallows into the bowl and stir.

Place into microwave for 45 seconds, remove and stir.

Return to the microwave and heat for another 45 seconds. Remove from the microwave and stir again.

Pour 6 cups Rice Krispies into the melted marshmallows and mix until well combined.

Distribute evenly and press firmly into the pan.

Sprinkle top with Halloween sprinkles.

Pro Tip: Place a Ziplock bag over your hand and spray the outside of the bag with non-stick spray before pressing down the Rice Krispie Treats. This helps to keep them from sticking to your hand!

Use Fresh Marshmallows – Fresh marshmallows melt more smoothly and create softer, chewier treats.

Mix Gently – Fold the Rice Krispies cereal into the melted marshmallows carefully so the cereal stays crispy.

Avoid Pressing Too Firmly – Gently press the mixture into the pan. Compacting it too much can result in dense, tough treats.

Add Sprinkles While the Mixture is Warm – Halloween Sprinkles will stick better before the treats cool and set.

Store in Air Tight Container – Rice Krispie Treats stay soft and fresh for up to 2-3 days at room temperature.
