Funfetti Rice Krispie Treats

These cake batter flavored Funfetti Rice Krispie Treats are so colorful and fun. Each marshmallow cereal treat bar is loaded with rainbow-colored sprinkles and is flavored to taste like a slice of yellow cake. These rice crispy treats are perfect for a birthday party or just a simple afternoon snack.

If you love a big slice of frosted birthday cake piled high with rainbow sprinkles then you are going to love this cake batter flavored Funfetti Rice Krispie Treats recipe.

Each bar tastes like a crispy version of a birthday cake.

To make these treats I started with our amazing Rice Krispie Treat Recipe, which has the perfect proportions of salted butter, marshmallows, and Rice Krispies Cereal. Then I added a splash of cake batter flavoring and lots of sprinkles.

You may have seen cake batter rice crispy recipes that call for adding actual powdered cake mix but I do not personally feel good about eating raw cake mix, so I would not recommend doing that.

Cake batter flavoring comes in a bottle, is safe to eat, and is really yummy. It makes rice Krispie treats taste like yellow cake.

Of course, these Funfetti Rice Krispie Treats also need to be speckled with lots of sprinkles. I chose to use rainbow sprinkles, also known as jimmies, sugar strands, or hundreds-and-thousands, but you can use single colors or blend your own color combination for any holiday or occasion.

Be sure to check out our Rice Krispie Treat FAQ page for great tips and tricks for making cereal treats including information about measuring marshmallows.

How to make Funfetti Treats

You will need:

• 4 tablespoons European-style Salted Butter (for the very best flavor)
• 10 ounces marshmallows (we recommend using Kraft Jet-Puffed Marshmallows)*
• 4 ⅔ cup Rice Krispies Cereal
• 4 tablespoons rainbow sprinkles
• an 8-inch or 9-inch square pan

*Some store brand marshmallows, like those from Kroger, have a nice flavor but are far too sticky for our recipe. If that is what you choose to use, you will want to add more cereal, about ½ cup to this recipe. Just know that your cereal mixture will be a little stickier to mix.

If you are using a pan with a nice non-stick surface your treats will most likely come right out, but I always grease my pan with a bit of butter or non-stick cooking spray just to ensure they will slide out easily.

Ingredients for a larger batch:

• 6 tablespoons European-style Salted Butter
• 16 ounces Kraft Jet-Puffed marshmallows
• 7 cups Rice Krispies Cereal (add an extra 1 cup if using store brand marshmallows)
• 6 tablespoons sprinkles
• a 9-inch by 13-inch pan

How many cups of marshmallows are in my bags?

Mini Marshmallows:

• Each cup of mini marshmallows weighs approximately 1.67 ounces.
• A 10-ounce bag contains approximately 6 cups of mini marshmallows.
• A 16-ounce bag contains approximately 9 ⅔ cups of mini marshmallows.

Standard (large) Marshmallows:

• Each large marshmallow is approximately 0.24 ounces.
  • Each brand of marshmallow weighs slightly different amounts.
  • 7-8 marshmallows = 1 cup of mini marshmallows
• There are approximately 40-48 marshmallows in a 10-ounce bag and 64-70 in a 16-ounce bag.
• Kraft Jet-Puffed Marshmallows are lighter than some other brands. If using them you’ll need 40 marshmallows for a recipe calling for 10 ounces and 64 for a 16-ounce recipe.
