  • Yield: 16 rice krispie squares 1x


These Rice Krispie Treats with Marshmallow Fluff are one of my favorite treats! Only 3 ingredients and 10 minutes of prep time. Perfect for the Holiday season.


  • 3 tablespoons salted butter
  • 7 ounce container of Marshmallow Fluff or Creme
  • 4 cups Kelloggs Rice Krispie Cereal


  1. Line the bottom of an 8x8 pan with parchment paper. Set aside.
  2. In a large pot, melt the butter over medium low heat.
  3. Add in the marshmallow fluff and stir for a few minutes to combine with the butter and warm it up.
  4. Turn off the heat on the stovetop. Pour in the rice krispie cereal and stir until combined.
  5. Pour the rice krispie treat mixture into the 8x8 pan. Slice a large piece of parchment paper and lay it on top of the rice krispie treats and press down with your hands to pack them down into the pan and even them out. Note: It's important to really pack them in so they don't fall apart when sliced.
  6. Add sprinkles if desired. Allow the fluff rice krispies to sit for an hour, preferably 2 hours before slicing into squares.
  7. Slice into squares or rectangles and enjoy!


  • Use an 8x8 pan for this recipe. A 9x13 will result in really thin rice krispie treats.
  • To avoid the rice krispie squares from falling apart, it's really important to press down on the surface of the rice krispies with parchment paper to pack them into the pan.
  • Allow the rice krispies to sit for at least 1 hour before slicing them.
