Summary list of ingredients:

Rice Krispies or puffed rice cereal – While the classic Rice Krispies brand works great, any puffed rice cereal will do the trick. Use whatever you have in your pantry!

Mini marshmallows – The essential ingredient for that gooey, melty texture that holds your treats together.

Rainbow sprinkles – For that signature Funfetti flair! I love using classic rainbow jimmies, but any colorful sprinkle will add fun and flavor.

Butter – Helps create that soft, chewy texture and adds rich flavor when melted with the marshmallows.

White vanilla extract – Just a splash (or more, if you're feeling generous) enhances the sweetness and depth of flavor in these Rice Krispie treats.

Instructions

  1. Line a baking dish with parchment paper for easy removal and cleanup.

  2. In a large pot over medium heat, melt the butter until it begins to brown slightly and smells nutty—this should take about 2–3 minutes. Browning the butter adds a rich, toasty flavor to your Rice Krispie treats.

  3. Remove the pot from heat and stir in the mini marshmallows. Mix until fully melted and smooth.

  4. Add vanilla extract and salt, then pour in the Rice Krispies cereal. Mix until everything is evenly coated in the gooey marshmallow mixture.

  5. Gently fold in the rainbow sprinkles to give your Rice Krispie treats that classic Funfetti look.

  6. Transfer the Funfetti Rice Krispie mixture to your prepared baking dish. Press it gently into an even layer. For extra fun, sprinkle a few more rainbow sprinkles on top!

  7. Let the treats sit at room temperature for at least 1 hour to firm up. Once set, lift them out of the pan using the parchment paper, slice into squares, and enjoy your colorful, chewy no-bake dessert!

Pro tip: Avoid refrigerating your Funfetti Rice Krispie treats—cold temperatures can make them hard and brittle. For best texture, store them at room temperature in an airtight container.
