Frankenstein Rice Krispie Treats
These adorable and spooky treats are fun to make and even more fun to eat! They're perfect for a Halloween party or a school snack.
Yields: 12-16 treats
Prep time: 20 minutes
Chill time: 30 minutes
Ingredients:
6 cups Rice Krispies cereal
1 (10.5 ounce) bag mini marshmallows
3 tablespoons unsalted butter
1 teaspoon vanilla extract
Green candy melts (about 10-12 oz), or white candy melts/frosting with green food coloring
Black sprinkles (preferably jimmie style, for hair)
Edible candy eyes (small size)
Black icing gel (for stitches and mouth)
Equipment:
9x13 inch baking pan
Parchment paper or aluminum foil
Large microwave-safe bowl (or large pot)
Spatula (greased)
Small microwave-safe bowl (for candy melts)
Piping bag or ziploc bag with a tiny corner snipped (for black gel icing)
Instructions:
1. Prepare the Pan:
* Grease a 9x13 inch baking pan with butter or cooking spray.
* Alternatively, line the pan with parchment paper or aluminum foil, leaving an overhang on the sides. This makes it easier to lift the treats out later. Lightly grease the paper/foil as well.
2. Make the Rice Krispie Treats Base:
* In a large microwave-safe bowl (or a large pot over low heat), melt the butter.
* Add the mini marshmallows and stir until completely melted and smooth. This can take 1-2 minutes in the microwave, stirring halfway, or about 5 minutes on the stovetop.
* Remove from heat (if using stovetop) or microwave. Stir in the vanilla extract.
* Add the Rice Krispies cereal to the marshmallow mixture. Using a greased spatula or spoon, gently fold until the cereal is evenly coated.
3. Press into Pan:
* Transfer the mixture to your prepared 9x13 inch baking pan.
* Using the greased spatula or your greased hands, gently and evenly press the mixture into the pan. Don't press too firmly, as this can make the treats hard.
* Let the treats cool completely at room temperature for at least 30 minutes, or you can pop them in the fridge for 15-20 minutes to speed it up.
4. Cut into Rectangles:
* Once cooled and set, lift the entire block of Rice Krispie treats out of the pan using the parchment paper/foil overhang.
* Place it on a cutting board.
* Using a sharp, greased knife, cut the treats into rectangles. You can cut them into 3 rows by 4 or 5 columns to get 12-15 "Frankenstein faces."
5. Melt the Green Candy Melts:
* Place the green candy melts in a small microwave-safe bowl.
* Melt according to package directions, usually in 30-second intervals, stirring well after each, until smooth and creamy. Be careful not to overheat.
* If using white candy melts/frosting: Melt as directed, then stir in green food coloring (gel food coloring works best for vibrant color) until you reach your desired Frankenstein green.
6. Decorate the Frankenstein Faces:
* Take one Rice Krispie treat rectangle. Dip about two-thirds of the top into the melted green candy, allowing excess to drip off. Alternatively, you can use a spoon or offset spatula to spread the green candy onto the top of each treat.
* Place the dipped treat onto a sheet of parchment paper.
* Immediately place two edible candy eyes onto the green "face" area.
* Immediately sprinkle black jimmie sprinkles along the top edge of the green candy for Frankenstein's hair. Gently press them slightly so they stick.
* Repeat with all the remaining treats.
7. Add Stitches and Mouth:
* Once the green candy has set (this happens fairly quickly), use the black icing gel to draw a zig-zag mouth and small stitch marks on each side of the face, near where a "neck bolt" would be. You can also add a scar or forehead stitch.
8. Chill and Serve:
* Let the decorated treats set completely (the green candy should be firm) before serving. You can place them in the refrigerator for about 10-15 minutes to speed this up.
* Store in an airtight container at room temperature for up to 3-4 days.
Enjoy your monstrously good Frankenstein Rice Krispie Treats!
