How to Make Frankenstein Halloween Rice Krispie Treats
Step 1: Prepare Your Dish
Butter a 9 x 13 casserole dish. This will prevent the treats from sticking.
Step 2: Melt the Butter
In a large pot over low-medium heat, melt the unsalted butter until it’s completely liquid.
Step 3: Add Marshmallows
Add the mini vegan marshmallows to the melted butter. Stir continuously until they have completely melted and formed a smooth mixture.
Step 4: Combine with Cereal
Pour in the rice krispie cereal. Use a spatula to stir until every piece is well coated with the melted marshmallow mixture.
Step 5: Set in Dish
Spoon the mixture into your prepared casserole dish. Press down firmly to create an even layer across the bottom.
Step 6: Cool Down
Allow the mixture to set at room temperature for about 30 minutes or until firm enough to cut.
Step 7: Cut Treats into Shapes
Once set, remove from the dish and cut into rectangles of various sizes for fun presentation.
Step 8: Melt Green Candy Melts
Place a bowl over a small pot of boiling water. Add green candy melts to this bowl and stir until fully melted. If too thick, add a teaspoon of vegetable shortening for smoother consistency.
Step 9: Dip Treats
Dip the top of each rice krispie treat into the melted green candy melts, then immediately dip into black jimmies sprinkles for decoration.
Step 10: Add Eyes
Secure two royal icing eyes on each treat while the candy melts are still wet.
Step 11: Pipe Stitches
Melt black candy melts in a microwave-safe bowl using 10-15 second intervals. Once melted, pour into a piping bag and pipe stitches onto each treat for an extra spooky touch.
Step 12: Final Set
Allow all decorations to set completely before packaging or serving.
