BEST Fruity Pebble Cereal Treats

I thought these fun and pretty cereal treats would be a good way to celebrate this week. Why? Because Jordan, my baby, turns 13 tomorrow! Somehow I went from a little baby to a 5-year-old to a teenager. (Honestly, I don’t know what’s worse: having a teenager or knowing I’m old enough to have a teenager…)

As hard as this new stage of parenting has become (and as hard as it will get over the next few years), I love watching Jordan grow up. Every age is my favorite, but I love having her be older and like gossip and Riverdale and shopping. I just have to remind myself when she’s talking to me like I know nothing that I love having her as a Starbucks buddy. She really is one of my best friends, and I cannot wait to see what the next few years bring us.

(I know what the next few years are going to bring me: lots of wine to cope.)

I post every year for Jordan’s birthday. Until recently, her favorite dessert for me to make was something Chocolate Mint related. After all, February 19 is National Chocolate Mint Day so when it be came her favorite dessert it was kind of fitting. I’ve made her Chocolate Mint Poke Cake, a Mint Chocolate Chip Cake Roll, and Mint Chocolate Brownie Cupcakes for past birthdays. Most recently, she’s fallen in love with Elmer’s Brown Sugar Pecan Pie, which is what she asked for last year and again this year for her birthday treat. (And HE has to make it. I’m not allowed to.)

The only other thing Jordan loves more than that pie is cereal. She’s obsessed with cereal; she’d eat it for every meal if I let her. Honey Nut Cheerios are what I make her eat for normal breakfasts because it’s sweet but not as bad for you as her favorites: Capt’n Crunch and Fruity Pebbles.

That’s why I decided that Fruity Pebble Krispie Treats were what I should make for her birthday post this year. Happy 13th my sweet girl!

Favorite Cereal Treats

If I’m being totally honest, plain old Rice Krispie Treats are not something I’d choose for dessert. If you add Butterfingers, then I’m more likely to say yes, but I still prefer pie. However, I do have a Pebbles Cereal addiction. I’ve made a few recipes with Fruity Pebbles: muffins and cookies, as well as a no bake dessert with Cocoa Pebbles and cookies with Cinnamon Pebbles. Basically, I like the cereal, a lot, but I’ve never made cereal treats with them, until now.

How to make Fruity Pebbles Rice Krispie Treats

  1. Use just the right amount of butter and marshmallows. I find the regular Krispie treat recipe on the box to be a bit dry for my taste. I want a gooey treat, not one that cuts the roof of my mouth.
  2. For goodness sake, use FRESH cereal, no matter the flavor. Stale cereal really tastes stale when you make these. Same goes for the marshmallows! FRESH ingredients, please.
  3. Use any Krispie or Pebbles cereal flavor you like (ahem, COCOA PEBBLES).
  4. To press the cereal in the pan and not have it stick to your hands, spray wax paper with nonstick cooking spray and use it to press down the treats. Works like a charm with no messy hands!

Just be sure to serve these to someone who will love them, like a 13 year old or her mother. 🙂

  1. Excellent recipe! I ended up only having a little over 6 cups of fruity pebbles and they still turned out perfect! We stored ours in the fridge to keep them a little more solid. They were soooo good and were devoured within 2 days!
