I love making these Fruity Pebbles Rice Crispy Treats that bring a twist on a classic favorite using unsalted butter, mini marshmallows, and vanilla extract combined with Rice Krispies and vibrant Fruity Pebbles. A pinch of salt balances the sweetness, making every bite a delightful burst of colorful flavor.

I recently discovered the coolest twist on an old favorite and I just have to share it. Let me tell you, these Fruity Pebbles Rice Krispies Treats are super fun to make and even more awesome to eat.
I started with 3 Tbsp of unsalted butter and melted it up with 1 (10 oz) bag of mini marshmallows, adding a dash of vanilla extract to kick things up a notch. Then I mixed in 4 cups of Rice Krispies cereal with 4 cups of Fruity Pebbles cereal and a pinch of salt and I couldnt believe how colorful and fun the result was.
This crispy, sweet treat really gives a new life to the classic recipe and its a great option for a quick snack or party dessert. Its by far one of the best Fruity Pebbles Rice Crispy Treats ive ever made and you gotta try it yourself!

FAQ
Fruity Pebbles Rice Krispies Treats Recipe Substitutions and Variations
- If you run out of unsalted butter, you can use salted butter or even a bit of coconut oil to keep the flavor nice.
- Don’t have mini marshmallows? Try using marshmallow fluff or even melt a few regular marshmallows until they’re soft to mix in.
- No vanilla extract available? A splash of almond extract could work or you can just leave it out.
- Instead of Rice Krispies, you might try using Rice Chex or another puffed rice cereal if that’s what you have on hand.
- If Fruity Pebbles are out, consider using Trix or any other colorful cereal to keep the fun look and taste.
Pro Tips
1. Make sure your pan is really well greased so the treats dont stick when you’re taking them out later.
2. Keep stirring the melted marshmallows constantly over the heat so they dont burn; its easy to overcook them if you get distracted.
3. When you mix the cereals into the warm marshmallow mix, be gentle so you dont end up crushing the cereal too much.
4. Press the mixture evenly into the pan using a spatula or your greased hands; a firm press makes the treats hold together better and makes cutting them into neat squares a lot easier.
