How to Make Frankenstein Halloween Rice Krispie Treats
Step 1: Prepare Your Dish
Butter a 9 x 13 casserole dish thoroughly to prevent sticking.
Step 2: Melt the Butter
In a large pot over low-medium heat, melt the unsalted butter.
Step 3: Add Marshmallows
Once melted, add the mini marshmallows. Stir continuously until they become smooth and fully melted.

Common Mistakes to Avoid

Overheating the Marshmallows: If you cook the marshmallows too long, they can become hard. Melt them slowly over low heat and stir until just smooth.

Not Buttering the Dish Properly: Skipping this step can lead to treats sticking to the dish. Ensure you coat the casserole dish evenly with butter.
-
Skipping the Cooling Time: Cutting treats too soon will result in a messy situation. Allow them to cool for at least 30 minutes before slicing.
-
Using Too Much Candy Melt: If you dip the treats too deeply in candy melts, they can lose their shape. Dip only the top and let excess drip off.
-
Forgetting Decorations: Leaving out eyes or sprinkles makes them less fun. Make sure to add these details for a festive look!
