Ingredients

  • 6 tablespoons butter cut into 6 to 8 pieces
  • 1 teaspoon vanilla extract
  • 1 (9-oz) crispy rice cereal
  • 16 ounces large marshmallows

Optional Toppings

  • 12 ounces white chocolate meltables plus 1 ½ tablespoons cooking oil for ghost shapes
  • 32 mini chocolate chips or candy eyes
  • sprinkles fall colored

Instructions

  • Preheat the oven to 350 degrees F (180 degrees C). Lightly grease a 9x13-inch baking dish.
  • Place butter pieces in bottom of the prepared dish. Add vanilla to baking dish, then add in marshmallows. Carefully pour cereal over marshmallows.
  • Bake in the preheated oven until until very lightly browned and marshmallows have melted, 13 to 15 minutes.
  • Stir mixture carefully until well combined. Press mixture into dish; let stand 1 hour to cool completely; mixture should be very well held together. Lightly grease a knife and cut into 12 or 16 squares.

Optional Toppings

  • Mini Ghosts: Melt white chocolate in a heatproof bowl over simmering water; stir occasionally or according to package instructions. Then, mix in 1 ½ tablespoons of cooking oil (like vegetable oil). To make the ghosts, drop 1 tablespoon of white chocolate onto a parchment or wax paper-lined baking sheet. Using a teaspoon, quickly spread into a ghost shape. Add mini chocolate chip eyes and refrigerate for 5 minutes.
  • Sprinkles: For a festive touch, scatter fall harvest colored sprinkles over the top of the Rice Krispies treats while they cool and set. Lay a mini ghost over the sprinkles.

Notes

  1. Sprinkles: Add sprinkles while warm so they adhere.
  2. Pressing Rice Krispies Treats: When mixed, lightly press the mixture into the pan—don’t compact too much or bars will be hard.
  3. White Chocolate Ghosts: When cutting the treats into 16 portions (4 rows by 4 rows), aim for each ghost to measure about 2.5 inches. When cutting into 12 portions (3 rows lengthwise and 4 rows in width), create ghosts approximately 3.5 to 4 inches in size.
