Make traditional Rice Krispie bars: Melt butter in a large pot, then stir in marshmallows until melted. Add Rice Krispies cereal and mix well. Add sprinkles: Stir in the colorful sprinkles for that extra pop of color and fun! 🎉 Press into an 8×8 pan: Gently press the mixture into the pan, making it double the thickness of regular bars. Top with M&M’s: Press M&M’s into the top while they’re still warm. 🍫 Pro Tip: For even more gooeyness, use extra marshmallows! 🤩
