How to Make Frankenstein Halloween Rice Krispie Treats
Step 1: Prepare Your Casserole Dish
Start by buttering a 9 x 13 casserole dish. This step is crucial because it keeps the treats from sticking, making it easier to cut them later.
Step 2: Melt the Butter
In a large pot over low-medium heat, melt 4 tablespoons of unsalted butter. This creates a rich base for your marshmallow mixture and adds incredible flavor.
Step 3: Stir in Vegan Marshmallows
Once the butter is melted, add one entire bag of mini vegan marshmallows. Stir constantly until they’re completely melted and smooth. This gooey mixture is what binds your rice krispie cereal together!
Step 4: Add Rice Krispie Cereal
Pour in 6 cups of rice krispie cereal. Using a spatula, gently fold the cereal into the melted marshmallow mixture until every piece is evenly coated. This step is important so each bite is deliciously chewy.
Step 5: Press into Dish
Spoon the mixture into your prepared casserole dish and press it down firmly until it’s flat on top. Making sure it’s compact helps your treats hold their shape when cut.
Step 6: Let It Set
Allow your rice krispie treats to cool and set for about 30 minutes. Patience is key here; letting them cool properly ensures they stay together nicely when you slice them!
Step 7: Cut into Shapes
Once cooled, remove from the dish and cut into rectangles of various sizes. Having different sizes adds character and makes them even more fun!
Step 8: Melt Green Candy Melts
To decorate, set up a double boiler by placing a bowl over a small pot of boiling water and add your green candy melts. Stir until melted. If it’s too thick for dipping, don’t hesitate to add a teaspoon of vegetable shortening.
Step 9: Dip in Candy Melts
Dip the top of each treat into the melted green candy melts, allowing any excess to drip off before coating with black jimmies sprinkles.
Step 10: Add Eyes
Gently place two royal icing eyes on top of each treat while the candy melt is still soft.
Step 11: Pipe Stitches
Melt the black candy melts in short bursts in the microwave (10-15 seconds). Once melted, pour into a piping bag and pipe little stitches onto each treat for that extra cute touch.
Step 12: Let Set Completely
Allow everything to set completely before packaging or serving. This will ensure all decorations stay perfectly in place!
Now you’re ready to enjoy these delightful Frankenstein Halloween Rice Krispie Treats! They’re bound to be gobbled up quickly—so make sure you save some for yourself!

- Use Fresh Ingredients: Always check the expiration dates on your marshmallows and candy melts. Fresh ingredients help achieve the best taste and texture, making your treats even more enjoyable.
- Grease Your Hands: When pressing the mixture into the casserole dish, grease your hands with a little butter or cooking spray. This prevents the sticky mixture from clinging to your fingers, making it easier to work with.
