How to Make Frankenstein Halloween Rice Krispie Treats

Step 1: Butter the Casserole Dish

Start by buttering your 9 x 13 casserole dish generously so that the treats do not stick.

Step 2: Melt the Butter

In a large pot over low-medium heat, melt the unsalted butter until it is completely liquid.

Step 3: Add Marshmallows

Once the butter is melted, add the mini marshmallows. Stir constantly until they are fully melted and smooth.

Step 4: Mix in Rice Krispie Cereal

Pour in the rice krispie cereal. Use your spatula to gently fold until all cereal is evenly coated with the melted marshmallow mixture.

Step 5: Press Mixture into Dish

Spoon the mixture into your prepared casserole dish. Press down firmly with your spatula until it fills the dish evenly and has a flat top.

Step 6: Allow to Set

Let the mixture cool at room temperature for about 30 minutes until it sets properly.

Step 7: Cut Treats

Remove the cooled rice krispie treats from the dish. Cut them into rectangles or fun shapes as desired.

Step 8: Melt Green Candy Melts

Set up a double boiler by placing a bowl over a small pot of boiling water. Add green candy melts to the bowl and stir until completely melted. If needed, add a teaspoon of vegetable shortening to thin it out.

Step 9: Dip Treats

Dip the top of each rice krispie treat into the green candy melts, ensuring they are well-coated. Then dip them into black jimmies sprinkles for added texture.

Step 10: Add Eyes

Place two royal icing eyes on each treat for that spooky effect.

Step 11: Melt Black Candy Melts

In another small bowl, melt black candy melts in the microwave using increments of 10-15 seconds until smooth.

Step 12: Pipe Stitches

Pour melted black candy melts into a piping bag. Carefully pipe stitches onto each treat to complete their Frankenstein look.

Step 13: Allow to Set Completely

Let decorated treats sit until all chocolate has set before serving or packaging them away for later enjoyment.

Common Mistakes to Avoid

When making Frankenstein Halloween Rice Krispie Treats, it’s easy to overlook a few key steps. Avoid these common mistakes to ensure your treats turn out perfectly.

Skipping the Butter: Not greasing the casserole dish can cause the treats to stick. Always butter the dish thoroughly before adding the mixture for easy removal.
Overheating Marshmallows: Melting marshmallows too quickly can make them hard. Use low-medium heat and stir gently until they are completely smooth for a perfect consistency.
Not Pressing Firmly: Failing to press down the mixture can lead to crumbly treats. Ensure you pack the rice krispies tightly in the dish for a sturdy texture.
Rushing Cooling Time: Cutting treats before they cool can result in messy shapes. Allow at least 30 minutes for them to set properly before slicing.
Ignoring Candy Melt Consistency: Using thick candy melts may cause uneven coating. If needed, add a teaspoon of vegetable shortening to achieve a smoother melting texture.
