Step‑by‑Step Instructions for Frankenstein Rice Krispie Bars

Step 1: Prepare Your Pan
Start by greasing and lining a 9x13-inch baking pan with parchment paper, leaving some overhang for easy removal later. This will ensure your Frankenstein Rice Krispie Bars are easy to lift out and cut. Set the prepared pan aside as you move on to the next step.

Step 2: Melt the Butter and Marshmallows
In a large saucepan over medium heat, melt the ¼ cup of unsalted butter. Once melted, add the 1 cup of mini marshmallows, stirring continuously until they're completely melted and combined. This usually takes about 2-3 minutes. Remove from heat as soon as the mixture is smooth and glossy.

Step 3: Mix in the Rice Krispies
Pour the 6 cups of Rice Krispies into the melted marshmallow mixture. Using a spatula, mix until the cereal is fully coated, which should take about 1-2 minutes. The mixture will be quite sticky, but make sure it's evenly combined to form a solid base for your bars.

Step 4: Press the Mixture into the Pan
Transfer the mixture to your prepared baking pan. With lightly greased hands or the spatula, firmly press the mixture down into an even layer, smoothing the top. Aim for a thickness of about an inch, as this will help your Frankenstein Rice Krispie Bars hold their shape when they cool.

Step 5: Melt the Green Coating
In a microwave-safe bowl, combine the 12 oz of green candy melts with 1 tablespoon of coconut oil. Heat in the microwave in 30-second intervals, stirring between each, until the mixture is smooth and glossy. This should take about 1-2 minutes total. Let it cool slightly before pouring.

Step 6: Coat the Rice Krispie Bars
Carefully pour the melted green candy coating over the pressed Rice Krispie mixture in the pan. Use a spatula to spread it evenly, ensuring every corner is covered with the vibrant green color. Allow the coating to set for about 15-20 minutes at room temperature.

Step 7: Add the Whimsical Decorations
Once the coating has set, it’s time to bring your Frankenstein Rice Krispie Bars to life! Use candy eyes to create adorable faces and black decorating gel to add spooky details. Be creative—each bar can be a unique little monster to liven up your Halloween festivities.

Step 8: Cut and Serve
When your decorations are complete, lift the bars out of the pan using the parchment overhang. Place them on a cutting board and cut into squares or rectangles, depending on your preference. Your Frankenstein Rice Krispie Bars are now ready to be shared and enjoyed by family and friends!
