Step One:

Use the 2 Tbsp. of melted (or softened butter) to grease a 9″ x 13″ baking dish.

Step Two:

Put the marshmallows and 4 Tbsp. butter in a large pot on the stove. Turn the stove onto medium-low heat and melt together the marshmallows and the butter.

Step Three:

Once the shapes of the marshmallows are no longer visible and you have a smooth cream, turn off the heat, and add 1 teaspoon of vanilla. Stir well.

Step Four:

Add the 6 cups of Rice Krispies cereal and stir well (make sure the cereal is completely coated with the marshmallow mixture).

Step Five:

Pour the Rice Krispie/marshmallow mixture into the prepared (greased) 9″ x 13″ baking dish.

Step Six:

With the back of a buttered spatula or large spoon, press the Rice Krispies into the pan. Sprinkle with optional sprinkles if you would like.

Step Seven:

Let cool for 20 minutes and enjoy!
