Ingredients You’ll Need
This line-up is delightfully short and sweet, using straightforward pantry staples to create the magic. Every ingredient pulls its weight in transforming a simple batter into the dazzling, gooey Funfetti Blondies we all crave.
- Unsalted Butter (melted): Infuses richness and helps deliver that classic chewy blondie texture. Melted butter also makes hand-mixing a breeze!
- Light Brown Sugar (packed): Gives the blondies their characteristic caramel notes and keeps the crumb moist.
- Large Egg: The binding superstar, adding tenderness and structure with the perfect amount of lift.
- Vanilla Extract: Deepens the flavor, making every bite taste like pure vanilla cake bliss.
- Almond Extract (optional): Adds a soft, bakery-style flair that makes Funfetti Blondies extra special.
- All-purpose Flour: The sturdy base for that tender-but-thick blondie bite we all love.
- Baking Powder: Just enough to give a little lightness without losing the dense, chewy texture.
- Salt: Balances sweet flavors—don’t skip it, even if it seems small.
- White Chocolate Chips: Creamy pockets of sweetness that pair beautifully with the colorful sprinkles.
- Rainbow Sprinkles (plus extra for topping): The heart and soul of Funfetti Blondies—use jimmies for the best look and color pop!
How to Make Funfetti Blondies
Step 1: Prep the Pan and Preheat
Start by preheating your oven to 350°F (175°C). Line an 8×8-inch baking pan with parchment paper, leaving a little overhang on the sides. This trick makes it ultra-easy to lift your Funfetti Blondies out in one neat slab, so slicing them is a breeze. Trust me, you’ll thank yourself when it’s time to serve!
Step 2: Whisk Butter and Sugar
In a large mixing bowl, whisk the melted butter and packed brown sugar until the mixture looks creamy and shiny. This step ensures the sugar fully dissolves and helps create those dreamy chewy blondie edges.
Step 3: Add the Egg and Extracts
Mix in the egg, vanilla extract, and almond extract (if you’re using it). Beat well until everything is combined and your batter becomes lighter and a bit thicker. The extracts bring that irresistible bakery aroma, so don’t skimp!
Step 4: Stir in Dry Ingredients
Gently add in the flour, baking powder, and salt. Mix with a spatula until just incorporated—too much stirring here can make your Funfetti Blondies tough instead of tender, so stop as soon as the flour disappears.
Step 5: Fold in the Fun
Now comes the best part—folding in the white chocolate chips and rainbow sprinkles. Use a gentle hand so the colors stay bright. Your dough should look like a party in a bowl!
Step 6: Bake and Top
Spread the thick, colorful batter evenly into your prepared pan and add a few extra sprinkles on top for good measure. Bake for 22 to 25 minutes, or until the edges are golden and the top has a beautiful crinkle. A toothpick inserted in the center should come out mostly clean with a few moist crumbs clinging on—it’s the secret to that soft, fudgy bite!
Step 7: Cool and Slice
Patience pays off here! Let your Funfetti Blondies cool completely in the pan—they’ll set as they rest and become much easier to slice into perfect squares. Grab the parchment “handles” and lift the whole slab out before cutting.
How to Serve Funfetti Blondies

Garnishes
Go ahead and have extra fun with garnishes! Add a cloud of whipped cream, a scoop of vanilla or birthday cake ice cream, or a drizzle of white chocolate. And, of course, a final flurry of extra rainbow sprinkles never hurts—it makes every square look as festive as it tastes.
Side Dishes
Because these blondies are sweet and celebratory, pair them with lighter sides like fresh strawberries or a bright citrus fruit salad. For all-out dessert happiness, serve alongside a cold glass of milk or frothy café latte. The contrast cuts through the sweetness and brings everything into delicious harmony.
Creative Ways to Present
Funfetti Blondies are delightful as classic squares, but you can totally get creative! Cut them into bite-sized cubes for a party platter, stack them in a “blondie cake” tower with candles for birthdays, or wrap individual pieces in colorful parchment for charming lunchbox treats. They even make sweet little favors at parties or picnics.
Make Ahead and Storage
Storing Leftovers
Keep your Funfetti Blondies ridiculously fresh by storing them in an airtight container at room temperature. They’ll stay soft and chewy for up to four days—just keep them away from heat or sunlight, which can melt the sprinkles and dry out the blondies.
Freezing
If you want to make these ahead or save extras, freezing is a fantastic option! Cut cooled blondies into squares, wrap each piece tightly in plastic wrap, then place them all in a freezer-safe bag or container. They’ll keep beautifully for up to three months, always ready for a colorful dessert emergency.
Reheating
When you’re ready for a treat, thaw blondies at room temperature for an hour or so. Fancy a warm, gooey bite? Pop a square in the microwave for five to eight seconds—just enough to soften the white chocolate pockets and make your Funfetti Blondie taste oven-fresh again!
FAQs
Can I use dark brown sugar instead of light?
Absolutely! Dark brown sugar will add a deeper molasses flavor and a slightly richer color to your Funfetti Blondies. It’s a great swap if you love a more caramel-forward taste, though the blondies will be just as soft and delicious either way.
Which sprinkles work best for Funfetti Blondies?
For picture-perfect blondies, stick with jimmies-style sprinkles—they hold their shape and rainbow punch during baking without bleeding color. Nonpareils and sanding sugars are less reliable since they can melt or blur into the batter.
Can I double the recipe for a bigger crowd?
Yes! To serve a party full of happy snackers, double the ingredients and bake in a 9×13-inch pan. Keep an eye on the bake time (it may need 3-5 extra minutes), and don’t forget to up the sprinkle quotient for major impact.
How do I get super chewy blondies?
Be careful not to overbake—pull the blondies from the oven when the center is just set and a toothpick shows a few moist crumbs. Also, avoid over-mixing the flour; both steps help guarantee that dense, gooey blondie texture everyone adores in Funfetti Blondies.
Can I make these gluten-free?
You sure can! Substitute the all-purpose flour with your favorite gluten-free baking blend (measure-for-measure style). Just check that your sprinkles and white chocolate chips are gluten-free, and you’ll be all set for golden squares of gluten-free joy.
Final Thoughts
There’s just something magical about a tray of Funfetti Blondies—each square is its own little party, bursting with color and big, nostalgic flavor. Whether you’re baking for someone special or simply treating yourself, give these blondies a try and watch happiness spread with every single bite!
