Frankenstein Rice Krispie Treats are spooky, sweet, and no-bake—perfect for Halloween! These gooey green squares, decorated with frosting hair, candy eyes, and pretzel bolts, are monstrously fun to make and eat.
To keep treats soft, don’t press the mixture too firmly into the pan. Store in an airtight container at room temperature with wax paper between layers. Use fruity marshmallows or chocolate Rice Krispies for fun flavor twists, but adjust coloring to maintain that signature green.
