Ingredients
  

  • 1/4 cup salted butter
  • 10 ounce bag of mini marshmallows
  • ½ teaspoon sea salt
  • 4 cups Rice Krispies cereal
  • 3 cups Fruity Pebbles Cereal

Instructions
 

  • Prep an 11×7 or 9×9 pan with non-stick cooking spray or by lining with parchment paper. Set aside.
  • In a large pot or saucepan, melt the salted butter over low heat.
  • Once butter is melted, add mini marshmallows and salt. Stir continuously as the marshmallows are melting. This will take about 2 minutes to get a nice creamy consistency. Do NOT over cook as that will make the marshmallow mixture set too hard.
  • As soon as the marshmallows are melted, remove pot from heat and pour in cereal.
  • Stir well, making sure the cereal if fully combined into the marshmallow cream.
  • Pour mixture into prepared pan and press flat.
  • Let cool for at least 30 minutes so the bars 'set'.
  • Tip pan upside down onto a cutting board and cut into squares. (If you used parchment paper, just lift the bars out.)
  • Serve.

Notes

  • After cooled to room temp, place your Rice Krispie Treats into an airtight container. They typically stay fresh for 3-5 days on the counter top.
  • You can also substitute out other cereal varieties if you'd like.

How To Store Your Rainbow Rice Krispie Treats

  • After cooling to room temp, place your Rice Krispie Treats into an airtight container. They typically stay fresh for 3-5 days on the countertop.
  • These bars also work well wrapped individually in plastic wrap. They are a sturdy option that travels well in lunch pails.
  • You can also place the air-tight container in the refrigerator for up to a week but I suggest you bring the bars to room temp before serving as they are harder to eat cold.
  • I do not recommend freezing them as they dry out easily.

Frequently Asked Questions:

  1. Can I use other cereal flavors? In short, yes. Feel free to substitute the plain Rice Krispies for any holiday version currently available. You can also use the Fruity Pebbles with Marshmallows if you’d like.
  2. What happens if I cook the marshmallows too long? If the marshmallows are cooked on too high of a heat, they tend to burn or have a slightly burnt taste. And if you overcook them, they will result in a bar that hardens too firmly to eat. Be patient during the marshmallow melting step as those two minutes make all the difference.
  3. Do I have to stir constantly when cooking? Yes, it’s important to scrape the bottom of your pot continuously when melting the marshmallows to ensure they don’t burn to the pot. A constant slow, gentle mixing technique is all you need. You don’t have to be aggressive.
  4. Why are my bars falling apart? If you don’t press the cereal mixture firmly enough into your pan, your bars won’t set well. They will become loose and crumbly and that’s when you find they’ll fall apart. If you’re struggling to get a good press, coat your rubber scraper with non-stick cooking spray to help.

Love this recipe. What's great is both cereals are gluten free so it's safe for that group too. Looks lovely.

These are so pretty! I have never made rice Krispie treats with Fruity Pepples but have always thought it would be really good. I am definitely going to make some with my kiddos now!
