Ingredients 

  • 8 tablespoons butter ½ cup or 1 stick
  • 16 ounces mini marshmallows divided
  • 1 teaspoon vanilla extract
  • 7 cups Fruit Pebbles crispy cereal

Instructions

  • Prepare a 13x9-inch baking pan by greasing it well with butter.
  • Optional: Toast cereal in a dry skillet over medium heat, stirring frequently, for about 5 minutes until lightly toasted and crunchy.
  • In a large pan on the stove, melt the butter over medium heat.
  • Reduce the heat to medium-low; add all of the marshmallows EXCEPT for 1 cup.
  • Stir constantly, until the marshmallows are melted.
  • Remove from the heat, and stir in the vanilla.
  • Add the cereal and the remaining one cup of mini marshmallows, and stir to combine well, making sure there are no dry pockets of cereal.
  • Add the cereal to the prepared pan, and use a spatula to spread it out to an even layer, taking care not to press or smash it down. If a spatula isn’t cutting it, get your hands lightly damp, and gently press out the cereal. A buttered bottom of a measuring cup also works well.
  • Let the rice crispy treats cool for 30 minutes before cutting and serving.

Notes

Marshmallow Tip: Melt your marshmallows at a low temperature. Use fresh marshmallows and stick to the mini ones. They melt more easily and the cup of them thrown in with the cereal looks so cute.
Perfect Texture: Don’t push the mixture too firmly into the pan. You want them to be light and airy so gently spread them but don't smash it down.
Seasonal Variations: Holiday-themed cereals make these treats perfect for any celebration - try them with Christmas Crunch or Halloween cereals. You can also add food coloring to the marshmallow mixture to match party themes.
Cutting Technique: Use a sharp, buttered knife to cut clean squares without dragging or tearing the treats. Wipe the blade between cuts for neat presentation, or use a pizza cutter for uniform pieces.
