How to Make Halloween Rice Krispie Treats

This no-bake easy recipe is so full of flavor. Let’s make them!

Use non-stick cooking spray to lightly coat the bottom of a 9×13 baking dish and line it with parchment paper. Then, follow these steps to melt your marshmallows.

Four-step process of making marshmallow mixture in a pot for Halloween Rice Krispie Treats: Step 1: Melted butter. Step 2: Marshmallows added. Step 3: Marshmallows starting to melt. Step 4: Melted marshmallows mixed with butter.
  1. In a large pot over low heat, melt the butter and stir in the salt.
  2. Stir in the marshmallows with the butter.
  3. Melt the marshmallows, stirring constantly.
  4. Add the vanilla.

Make sure to stir constantly so it does not burn. Remove the pot from heat as soon the mixture is fully melted.

Add the crispy rice cereal into the pot along with the other mix-ins.

Gently stir the mixture until evenly combined.

Tips and Tricks

Store leftovers in an airtight container or on a plate covered with plastic wrap. You don’t have to refrigerate these yummy marshmallow treats. I recommend eating within about two days.
