Frankenstein Rice Krispies Treats

I spent my summers at our cabin on Sugar Lake in Minnesota when I was a kid. We were in the water all day every day, except every now and then we had a rainy day.

We either played games or watched movies when it wasn’t lake weather. We biked to the Glen Store, which was a tiny little gas station and café. The gas pumps were so old they reminded me of the Andy Griffith show! They only had a few VHS tapes to rent, so we would watch those on repeat.

One of the few movies they had, which was pretty random, was Young Frankenstein (the old black & white movie). I absolutely loved it! From then on Frankenstein has been my favorite Halloween character!

So of course I had to make Frankenstein Rice Krisipie Treats!

How to Make 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.

Add a few drops of neon green food coloring to the melted marshmallows and mix until well combined. Add additional drops to reach desired color if necessary.

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

Distribute evenly and press firmly into the pan.

Cut into 12 pieces, giving you rectangle shapes.

Separate onto parchment paper.

Melt 2 cups chocolate chips in the microwave in 30 second intervals, stirring between each interval, until smooth and creamy.

Dunk one end of a Rice Krispie Treat 1/3 of the way into the melted chocolate. Sprinkle with chocolate sprinkles and set on the parchment paper. Repeat until all of the treats have ‘hair.’

‘Glue’ 2 Reese’s Mini’s for bolts with a dot of melted chocolate about 2/3 of the way down on the side of the treats.

‘Glue’ 2 candy eyes onto each treat.

Then pipe on the mouths.

Let harden.

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!
