FREQUENTLY ASKED QUESTIONS:

What kind of Rice Krispies should I use?

We use regular Rice Krispies for this recipe, but other flavors can be used such as cinnamon sugar, strawberry, frosted, etc. They should all work as this recipe is basic and no extra flavoring is added.

What chocolate is best to use?

We prefer to use a higher quality chocolate so it melts nicely. You can use a chocolate bar, chocolate chips or even melting wafers for this recipe.

Do I have to use gel food coloring?

Yes, this is essential to use when you are coloring chocolate. Liquid will make the chocolate seize so gel will help solve that problem.

Can I add more flavor to these?

If you want to add some more flavor to this recipe you can add in 1 1/2 teaspoons of vanilla extract into the marshmallows after they are melted and you add in your Rice Krispies.

What marshmallows should I use?

You can use regular or mini marshmallows. I used a mixture of strawberry and regular to add a little bit of flavor and color to these but you can use any color of flavor that you would like!

Can I double this recipe?

Absolutely, this makes a 9×9-inch pan of bars, just double this and you can make it in a 9×13-inch pan instead.

How do I store leftovers?

These can be stored in an airtight container in the refrigerator where they will keep for up to 5 days. I do not recommend freezing this recipe.

INGREDIENTS NEEDED: (FULL RECIPE AT THE BOTTOM OF THE POST)

  • marshmallows
  • unsalted butter
  • rice krispies cereal
  • white chocolate
  • gel food color
  • eye-shaped candies
  • colored sprinkles or jimmies 
Ingredients needed: marshmallows, unsalted Butter, Rice Krispies cereal, white chocolate, gel food color, eye-shaped candies and colored sprinkles or jimmies.

HOW TO MAKE HALLOWEEN RICE KRISPIES MONSTERS:

Line a 9×9-inch square baking pan with parchment paper – making sure it covers the bottom and goes up the sides (this will make it easier to remove them later to cut.) Place the marshmallows and butter in a large microwave-safe bowl.

Butter and marshmallows melted in bowl.

Microwave on high for 1 minute, stir to combine. Continue until everything is melted and smooth, this should only take 2-3 intervals. Once it’s completely melted, add the Rice Krispies and stir well to combine.

Rice Krispies added to marshmallow mixture.

Pour the mixture into the prepared pan and press down until evenly flat. I like to spray my hand with nonstick cooking spray and press down flat. Refrigerate it for at least 4 hours (or overnight). Note: getting them cold helps them to keep their shape when dipping into the melted chocolate. You can also freeze them for an hour or so to speed up the process.

Take bars out from the refrigerator and remove the rice Krispies from the pan using the extra parchment paper on the sides. Run a sharp knife under hot water for a few seconds to warm it up, wipe it dry, and then use it to cut the rice Krispie treats into rectangular pieces. Microwave the chopped white chocolate along with 1-2 teaspoons of oil at 20 seconds intervals until melted (stir after each interval). Once melted, divide it equally into 3 parts and add the gel food colors of your choice and mix well (I used green, orange, and blue).

At this point you can either dip the Rice Krispies treat directly into the colored chocolate OR use a spoon and pour the melted chocolate over it to make the monster heads OR you can even slather the melted chocolate using a butter knife (the coating doesn’t have to be perfect, just choose a way that you’re comfortable with). Once done, set it on parchment paper. Now, gently press the candy eyes and sprinkle the upper part of the head with your favorite sprinkles to give it a Halloween-y look. Repeat with all the pieces. Refrigerate for about 20-30 minutes or until the chocolate sets. Serve and enjoy!
