Funfetti Cake Batter Blondies

I think Funfetti gets its name because it just tastes fun.

And blondies that taste like cake batter are pretty fun, too.

Funfetti Cake Batter Blondies - Super soft & buttery blondies that taste Funfetti Cake Batter! Made from scratch in less time than it takes to use a boxed mix!

The recent tragedy that’s been all over the news has served as a reminder that no matter how busy my life is, and how many different directions I’m being pulled in, that my almost six-year old daughter is my greatest gift and to savor and appreciate each day I have with her even more, stop and smell more roses, give more hugs, and eat more blondies. I made these for my pink-loving princess and wanted her eyes to light up upon seeing them.

I combined two of my favorite flavors, Funfetti and yellow cake batter, for these sweet and easy blondies, complete with semi-sweet and white chocolate chips, and plenty of sprinkles. Sprinkles put the fun in Funfetti.

Many cake batter-flavored recipes that I read online use cake mix, which isn’t a shocker since cake mix is a logical ingredient in cake batter. However, I wanted to create cake batter-flavored without using a mix, just because I like to complicate things.

The from-scratch batter comes together quicker than if cake mix was used, can be mixed by hand in less than five minutes, and the blondies are ready from start to finish in thirty minutes. So take that, boxed mix.


Make the batter by melting one stick of butter, add brown and granulated sugars, an egg, and a healthy dose of vanilla. There’s a higher ratio of brown to granulated sugar, which keeps the blondies extra moist and they stay moist for days. Brown sugar draws in moisture from the air as time passes, and helps to keep baked goods soft over time. Unlike my other blondie recipes that strictly rely on brown sugar, a bit of granulated is used here to provide more authentic yellow cake flavor.

The secret ingredient that provides that telltale yellow birthday cake meets Funfetti flavor quality comes from the vanilla. If you think I’m going to say I used high-end, expensive, real vanilla extract, you’re wrong. This is a rare situation in baking where imitation vanilla extract, specifically clear, is preferred to real.


I learned from the Momofuku Milk Bar cookbook that imitation vanilla provides a nostalgic, classic Americana flavor. Taking a whiff of clear imitation vanilla is akin to burying my nose in a box of yellow or Funfetti cake mix crossed with a white grocery-store bakery cake, complete with inch-thick white frosting. I grew up with white sheetcake birthday cakes and clear imitation vanilla brings me right back to 1986, the roller rink, blowing out my birthday candles, and it’s perfect in the blondies.

Clear imitation vanilla is typically sold next to real vanilla extract for a fraction of the cost. Real vanilla extract may of course be used here, but for $2.99 clear imitation is fun to keep around, especially for white cakes or white frosting. It lends a comforting flavor profile and doesn’t impart any twinges of brown in frosting I want to keep bright white. This reminds me of the butter extract discussion.


After adding one tablespoon of vanilla, flour, white and semi-sweet chips, or mix-and-match as desired because there’s no wrong way to do Funfetti, I added a heaping quarter cup of sprinkles to the batter. After pouring the batter into the pan, I sprinkled with an additional tablespoon, mostly for a visual pop of color. Being skimpy with sprinkles is never good.

Bake the blondies just until the top has set, taking care not to overbake. They’re meant to be soft and tender.


They’re moist, dense, and taste like Funfetti birthday-cake cake batter. The vanilla adds a special touch and gives the blondies that luscious cake-batter scent. They remind me of all the beaters coated in cake batter I ever licked.

The chocolate chips and white chocolate chips add just enough chocolate and their presence is nice and noted, but they don’t overpower the more delicate cake batter flavor. And having little bits of sprinkles between my teeth in each bite adds welcome texture to the soft, doughy blondies.

My job was done when I saw the smile on my daughter’s face as she bit into this.

Prep time
Cook time
Total time
The flavors of Funfetti and yellow cake batter are paired in these sweet and easy blondies, complete with semi-sweet and white chocolate chips, and plenty of sprinkles. They don't rely on boxed cake mix, and the from-scratch batter can be mixed by hand in less than 5 minutes. The blondies are dense, soft, ultra-moist, and Fun.
Serves: one 8-by-8-inch pan, 9 generous squares
  • ½ cup unsalted butter, melted (1 stick)
  • 1 large egg
  • ¾ cup light brown sugar, packed
  • ¼ cup granulated sugar
  • 1 tablespoon clear imitation vanilla extract (real vanilla extract may be used, see note below)
  • 1 cup all-purpose flour
  • ¼ teaspoon salt, optional and to taste
  • ½ heaping cup white chocolate chips
  • ½ cup semi-sweet chocolate chips
  • ¼ cup rainbow-colored sprinkles, for batter
  • 1 tablespoon rainbow-colored sprinkles, for sprinkling top surface
  1. Preheat oven to 350F. Line an 8-by-8-inch pan with aluminum foil, spray with cooking spray; set aside. In a medium microwave-safe bowl, melt the butter, about 90 seconds. To the melted butter (allow it to cool slightly so you don't scramble the egg), add the egg, sugars, vanilla, and whisk to combine. Note regarding vanilla extract - clear, imitation vanilla extract helps provide classic Funfetti cake batter flavor in a nostalgic, classic, Americana birthday-cake kind of way. It's sold in clear bottles next to real vanilla extract, for a fraction of the cost. Real vanilla extract may be used, but it will darken the batter slightly and isn't quite as spot-on for flavor, but is acceptable.
  2. Add the flour, salt, and stir until just combined, taking care not to over-mix or the bars will be tough. Fold in white and semi-sweet chocolate chips (or a combination of your favorite kinds of chips) and ¼ cup (or more) sprinkles. Pour batter into prepared pan, smoothing it lightly with a spatula or offset knife if necessary. Sprinkle with about 1 tablespoon additional sprinkles for a nice visual pop of color.
  3. Bake for 18 to 24 minutes, or until center is set and golden or until edges begin to slightly pull away from sides of pan, or a toothpick comes out clean; do not overbake. Allow blondies to cool completely in pan before slicing and serving, at least one hour. Blondies may be stored in an airtight container at room temperature or in the refrigerator for up to 1 week, or in the freezer for up to 3 months.
  4. To keep gluten-free, use your favorite gluten-free flour blend, taking care that all other ingredients used are acceptable for your dietary needs.

  3. These look like they’ll be a fun and yummy bar to make. Seeing the joy and the smile on a child’s face is the best feeling ever. Or even listening to them sing b/c their so happy always makes my heart soar. Hold your daughter real close and doing even little things that make her happy and feel very loved and safe is something she’s always going to remember and treasure when she grows up.

  4. I agree with you – when crazy, tragic things happen as it did last week, it reminds me to have FUN, to let loose and smile more. Enjoying a tray of blondies with the ones we love definitely qualifies!

  5. Love the bright and colorful funfetti cakes but I’ve never seen them in blondies before. Great idea!

  6. I keep a jar of sprinkles around to put on my banana soft serve….and putting them in blondies would be fun! This is a nice dose of cheer after last week’s news. Children these days seem to be growing up in crazy times…such a shame because the potential risks and dangers they face are ones I never had to think about. No doubt Skylar loved these!

    • Only one jar of sprinkles kept around? Oh wow, the cupboard space I’d free up if I could do that :) And you’re so right…when I was a kid, we rode bikes all over town by ourselves when we were like 7 years old. Can’t even imagine that today!

  7. hmmm i love any dessert with “cake batter” in it, and funfetti makes everything better! i am a 5th grade teacher and need to make a treat this week for our holiday party… i bet they would LOVE these!!

  8. Definitely hugging our children a little tighter. And sprinkles bring smiles to anyone’s face. These look great Averie!

  9. “Sprinkles put the fun in Funfetti” — yes, yes they do. ;) I love your homemade version of Funfetti, you are much more ambitious than I am, ha! But let’s be serious, from scratch or from a box, anything involving sprinkles and sugar is bound to be a success. :)

  10. You said it girl. We all need to appreciate everyone we have in our lives every day.

    I love the sound of these bars and even more so love that they don’t actually have cake mix! WIN.

  11. Love funfetti and it’s so wonderful you made these for your daughter. I try to stay very present in life and treasure it, but terrible events like in Connecticut serve as a reminder that life is very fragile. I made the Momofuku confetti cookies using imitation vanilla as stated and loved them but not that weird artificial aftertaste. I still like the flavor of real vanilla no matter the dish.

  12. I love that you didn’t use a cake mix for these! They sounds SO easy!

  13. I was reminded of the same things this weekend…to never take for granted the lives that have been entrusted to us. And to cherish the hugs, smiles, holding hands and more that my littles give to me even more than I already do! These funfetti bars sure are perfect for getting a smile from anyone!!! They look soft and chewy and perfect!!

  14. The real reason I never have done funfetti bars or cookies is because I wasn’t crazy about using a boxed mixed. Problem solved! These just look happy :-) Must be the sprinkles!

  15. I could absolutely go for a blondie right now. Next time totally adding sprinkles.

  16. I agree with freeing up cupboard space with less sprinkles! I think I’ve got about 6 different ones right now. My youngest daughter’s birthday is coming up, I know she would love these, as she too is a pink-loving princess. Plus, everything is better with sprinkles, right?

  17. I think we deal with the news from CT the same way: we bake. I baked so much this weekend and cried and hugged my kids tighter. I love these blondies. Sprinkles are bound to make you smile!

  18. Love these blondies, Averie! I bet your daughter savored each one! :)

  19. I am salivating!

    Amazing recipes!

  20. I love that we’re so often on the same wavelength when it comes to our oven creations. :D Your blondies remind of a fabulous 90’s slumber party-with midnight fridge raids, NKOTB gossip, Truth or Dare?, and discussions about the latest Babysitter’s Club book. Awesome! I’ll remember to pick up some imitation vanilla the next time I’m out shopping!

    • Thanks for the Pin my friend :) And our oven creations are eerily similar many times! NKOTB and can I get a friendship bracelet to go with that and some Rave hairspray please? :) Omg we must have grown up in the same town with babysitter’s book club and maybe some Debbie Gibson and a Trapper Keeper, too!

  21. Love these. And what a lovely, lovely treat for your precious daughter. I hope you have the chance to share a special moment, some hugs, and maybe a few blondies with her today.

  22. Interesting notes about the imitation vanilla, now I have to buy some! I love funfetti, though I have never made it. The combo with the blondies is brilliant!

  23. Yummy! They look so good. I LOVE sprinkles.

  24. These look fabulous, from the chewy center to the slightly crispy top.

  25. Mmmmm, I love funfetti! I gave up using cake mix a long time ago, but I would definitely make these blondies… like right now.
