Funfetti Rice Krispie Treats Recipe
The best part about this Funfetti Rice Krispie Treats recipe is the amazing cake batter flavor that comes from Funfetti cake mix mixed right in! We'll heat treat the cake mix to make sure it's safe to add in, and it gives these treats such amazing festive flavor!
Ingredients
Ready to get started? Here's what you'll need:
- butter - I like to use salted butter to help bring out the flavors in these birthday cake rice krispie treats! You can also use browned butter for even more flavor!
- marshmallows - you'll need mini marshmallows to get that gooey texture! Save some to add in later to have gooey marshmallows showing when you cut individual treats!
- cake mix - for the funfetti look and birthday cake flavor, you can use white cake mix with sprinkles added, or funfetti cake mix (we'll quickly heat treat the cake mix to make sure – see the recipe card below for instructions)
- vanilla - even when making classic rice krispie treats, I always use a high-quality pure vanilla extract. Or better yet, check out my post on how to make vanilla extract at home with just 2 ingredients!
- Rice Krispie cereal - forms the base of our rice krispie treats! Be sure to measure out your crispy rice cereal ahead of time so you can easily add it in!
- rainbow sprinkles - in the recipe card below I say use ⅓ cup, but measure with your heart! Plus, you'll need extra to add on top!
- frosting - and what's cake without a layer of frosting? I like to make this rice krispies treats recipe super easy and use store-bought frosting to spread on top of the bars, but you can always make a double or triple batch of the frosting from my Mini Vanilla Cake!
See recipe card below for ingredient measurements.
Equipment
First, you'll need a large bowl to mix everything in, and a sheet pan or a small bowl for heat-treating your cake mix. You'll also want a rubber spatula to mix everything up!
Once it's mixed, you'll put everything into an 8x8 baking pan to cool. You can also use a round cake pan! Check below for more tips to make this no bake dessert even more festive!
Instructions
Scroll down to the recipe card below for full instructions, but here are the basic steps for this birthday rice krispie treats recipe:
Melt butter in microwave in a large mixing bowl. Add most of marshmallows (save about a cup) and cake mix and heat again in microwave to melt.
Stir melted marshmallows mixture until smooth, then add remaining marshmallows, sprinkles, and cereal.
Press cereal mixture into a buttered 8x8 cake pan (or one that has been lined with plastic wrap for easy clean-up).
Let cool completely to firm up, then spread frosting on top and add lots of sprinkles!
Hint: Let your birthday rice krispie treats cool completely at room temperature, uncovered. This will allow any moisture to evaporate to prevent soggy treats.
Rice Krispie Treat Cake Ideas
How can you make this birthday cake rice krispie treats recipe even more party perfect? Here are some ideas:
- Round cake pan - use an 8-inch round cake pan instead of a square pan to make
- Layer cake - split this cake into two cake pans and layer frosting in between and on top to make it into a delicious layered birthday cake!
- Chocolate covered - Top it with melted chocolate or chocolate ganache (equal parts chocolate and heavy cream) instead of frosting!
- Color options - Add colorful frosting, or switch out the sprinkles for different colors depending on your preference, or the season!
- Candles - don't forget the birthday candles!

Heat Treating your Cake Mix for Birthday Rice Krispie Treats
It's important to note that cake mix is NOT safe to eat straight from the box. It's a common misconception that wheat flours (and cake mixes containing flour) are safe from germs because they don't contain raw eggs. On the contrary, "germs are only killed when flour is baked or cooked" (CDC).
So to make these delicious birthday cake rice krispie treats as safe as possible, we'll heat treat our cake mix! Simply measure out the cake mix you'll need for this recipe (½ cup) and add it to a microwave-safe bowl. Heat on high for 30 seconds, stir, and measure the temperature with a food thermometer. If it hasn't reached 165 degrees Fahrenheit, heat it for another 30 seconds, repeating the process in 30 second intervals until the temperature reads 165 degrees.
Storage
For the best results, I would recommend enjoying these treats the day you make them. But if you do store them for later, be sure to let your rice krispie treats cool completely so any excess liquid can evaporate before storing.
They should be good at room temperature for up to 3 days in an airtight container, or they can be frozen, well wrapped in plastic wrap or parchment paper, for up to 2 months.
Top Tip
Don't forget to heat treat your cake batter! Whether you microwave it or heat it in the oven, use a food thermometer to check that it has reached at least 165 degrees F before mixing it in.
Frequently Asked Questions
In my experience, it's much more affordable to make your own -- you can make several batches from one box of crispy rice cereal, and with only three base ingredients, it definitely won't break the bank!
But more importantly, the taste and texture difference is off the charts! I can't imagine buying packaged rice krispie treats when it's this easy to make them myself and they're SO much better!
I would make this birthday cake rice krispie treats recipe no more than 2 days before you plan to enjoy them!
It's every year on September 18th! Definitely one of my favorite food holidays because it's so easy to celebrate! Try my Fancy Rice Krispie Treats with Brown Butter and White Chocolate Ganache for an even more decadent treat!
