What I love about this Easy Halloween Treat Idea

• Making one large Halloween Rice Krispies Treat means less time spent in the kitchen and still provides a wow factor that will be a big hit
• You can’t go wrong with making rice krispies treats for the holidays. Kids, teens, and adults love this classic treat

Ingredients

Here’s what you’ll need for this easy Halloween dessert

• Mini Marshmallows – You can use regular. I prefer mini because it is easier to melt tiny marshmallows and quicker. Don’t forget to reserve a couple for Frankenstein neck bolts
• Butter – Use unsalted butter and be careful not to burn the butter on the stovetop. Watch it closely as it melts
• Rice Krispies Cereal – You’ll use a good amount of cereal (around 6 cups), so it’s best to get a fresh new box
• Food Coloring – You’ll want to color your melted marshmallows so it is close to the green you think of when you see Frankenstein
• Frosting – Chocolate frosting is already dark brown which is perfect for this fun Halloween treat
• Sprinkles – this is not completely necessary but I think it makes the hair look more like a hair texture
• More marshmallows – You will only need one regular-sized marshmallow for the eyes
• M&Ms – I used the Halloween green, but brown would also work well for this Frankenstein treat
• Gel Decorating Gel – I used black for the pupil of Frank’s eyes

Equipment You’ll Need

• A 9×13 baking dish to mold this treat
• Parchment paper
• A piping bag, coupler, and writing tips for making the stitches and eyebrows (you could also use a larger round tip for a bigger impact)

How to Make a Large Frankenstein Rice Krispies Treat

Step One

In a large saucepan over medium heat, add butter and melt it

Once the butter is melted add the marshmallows

Reduce heat to low and stir marshmallows until they are melted

Remove from heat

Step Two

Add some food coloring and stir in – Add more if you want a darker color

Pour rice crisp cereal into a large mixing bowl and fold in the colored marshmallow

Line a baking dish with parchment paper

Step Three

Scoop the rice krispies cereal into the baking dish and spread out

Let it cool off enough for the marshmallows to harden a little bit, so when you lift it up out of the pan it won’t fall apart

Once the marshmallows have set up a little bit, lift the parchment paper up and out of the baking dish

Decorating

Spread some of the chocolate frosting onto the top part of the rectangle, pulling some down into jagged edges for Frank’s bangs

Sprinkle chocolate sprinkles onto the frosting

Use kitchen shears the tips off of a regular-sized marshmallow

Place those tips onto the rectangle for the eyes

Add M&Ms to the center of the marshmallows and black gel for the pupils

Scoop the rest of the chocolate frosting into a piping bag that has been set up with a writing tip

Draw stitches for a mouth and eyebrows

You can also add some more stitches to Frank’s forehead

Add a couple of mini marshmallows on the neck portion for Frank’s bolts

When the frosting has had time to dry and harden, you can transfer Frank onto a tray and cut the large rice krispies treat into smaller rectangles

Expert Tips

• Watch your butter so it does not burn. I’ve had to scrap butter and start over so many times
• Also, watch your marshmallows so they don’t burn. Turn the heat off if it is getting too hot and just stir until the marshmallows melt
• If your marshmallows cool off too quickly and won’t stir into the cereal, pop them into the microwave for about 10 seconds

Variations

You can cut the large rectangle into about 20 smaller ones and decorate them individually

Instead of marshmallow bolts, you can use the tips of large pretzel rods for bolts or Rolos candy

Use melting chocolate instead of frosting for decorating
