  • 1
    Place waxed paper on a large work surface where you will build your rainbow. Separate Fruity Cheerios™ into five colors. You need 1-1/4 cup of each color.
  • 2
    In microwave-proof bowl, put 10 large marshmallows and one pat of butter (about 1-1/2 tbsp). Microwave on high for 45 seconds. Remove from microwave and stir. Return to microwave and cook another 45 seconds on high.
  • 3
    Remove marshmallow mixture from microwave and stir it well, until it is smooth and completely mixed. It will be very liquid. Add 1-1/4 cups of the purple cereal to the marshmallow mixture. Mix well and place on waxed paper to cool just a bit.
  • 4
    Spray hands with cooking spray. When mixture is cool enough to handle but still warm enough to shape, mold the mixture into a long rope and place it in an arc around a 7 inch diameter bowl, pressing and pulling the cereal mixture until it is uniform thickness.
  • 5
    Repeat Steps 2-4 for the other colors in this order: green, yellow, orange and red. Press each color to the one before it so the colors stick to each other to form the rainbow.
  • 6
    Allow the rainbow to set completely before moving to a tray. Cut into thin slabs to serve.

More About This Recipe
These marshmallow-cereal bars shine in the brightest colors this side of Oz…

Turns out, Fruity Cheerios are good for a whole lot more than doing the back stroke in a bowl of milk. These colors were meant to morph into rainbow stripes in these Rainbow Fruity Cheerios Bars!

If  you rocked at the sorting game when you were a kid, you’ll totally kick buns at sorting a box of Fruity Cheerios into the five separate colors. Turn on the timer – really – this is a competitor’s idea of a good time.

The goal is to go from this:

To this:

That’s about 1-1/4 cup of each beautilicious color. Then it’s just a matter of the 3 M’s:

Microwave -- In a microwave-proof bowl, microwave marshmallows and butter on high for 45 seconds. Stir, and microwave another 45 seconds.

Mix -- Stir the mixture until it’s super smooth, then add the purple cereal and mix well.

Mold -- Place the mixture on waxed paper and let it cool just a titch. When it’s cooled enough not to send you to the burn unit, spray some non-stick cooking spray on your hands and mold the colored marshmallow menagerie into a long thin rope.

Wrap the rope around a bowl, pulling and pressing the mixture so it makes an even stripe. So, now the purple stripe is done. Just 4 more colors to go.

Here’s how it shapes up:

Pay no attention to the man behind the curtain, but grab your ruby slippers and check out the rainbow you just made!

Chop off the ends so they’re level and put your rainbow out on a nice big tray for all to admire. What a cool centerpiece for your next party! (Just keep Toto away. Way away.)

To serve it, just cut ‘er up into slabs of rainbow heaven:

Then pop your 70th anniversary edition of the Wizard of Oz into the DVD player, and start munchkin munchin'!
