Ingredients You’ll Need
The ingredient list for Funfetti Blondies keeps things refreshingly simple but absolutely irresistible. Each element serves a unique purpose, from tenderness to taste, and most are pantry staples you likely already have. Here’s what you’ll need to craft these festive bars:
- All-purpose flour: Gives the blondies structure while keeping the crumb perfectly tender and chewy.
- Baking powder: A little leavening ensures just the right lift without losing the dense, fudgy texture blondies are known for.
- Salt: A pinch sharpens the sweet notes and balances all the flavors.
- Unsalted butter, melted: Adds rich flavor and moisture; melting it makes for extra fudgy bars.
- Light brown sugar, packed: The molasses in brown sugar gives these blondies depth, chewiness, and that signature caramel taste.
- Large egg: Binds everything together while adding structure and that beautiful golden hue.
- Vanilla extract: Rounds out the sweetness and brings a comforting, aromatic note to the batter.
- White chocolate chips: Creamy bursts of sweetness in each bite, perfectly complementing the fun texture of the sprinkles.
- Rainbow sprinkles: The star of the show! They add a playful crunch, irresistible color, and celebratory flair.
How to Make Funfetti Blondies
Step 1: Prep the Pan and Oven
Start by preheating your oven to 350°F (175°C). Line an 8×8-inch baking pan with parchment paper, leaving a bit of overhang on the sides so you can effortlessly lift out your Funfetti Blondies after baking. This little trick makes cleanup a breeze and ensures cleaner slices every single time.
Step 2: Mix the Dry Ingredients
In a medium bowl, whisk together the flour, baking powder, and salt. This quick mix helps the leavening and salt disperse evenly throughout the flour, setting you up for blondies with a uniform, craveable texture in every bite.
Step 3: Combine the Wet Ingredients
In a large mixing bowl, whisk your melted butter and brown sugar until the mixture becomes smooth and shiny. This step builds the blondie’s signature butterscotch base, and the warmth of the melted butter melds with the sugar for maximum chewiness.
Step 4: Add Egg and Vanilla
Crack in the egg and pour in that fragrant vanilla extract. Whisk until everything is fully combined—your batter will look dreamy and luscious, just begging to be scooped.
Step 5: Bring It All Together
Gradually add your dry ingredients to the wet mixture, stirring just until you no longer see streaks of flour. Over-mixing can toughen your bars, so use a gentle hand for blondies that stay moist and tender.
Step 6: Fold in White Chocolate Chips and Sprinkles
Gently fold in the white chocolate chips and, of course, those envy-inducing rainbow sprinkles! Distribute them evenly so every Funfetti Blondie delivers that burst of color and creamy chocolate in every bite.
Step 7: Fill the Pan and Bake
With a spatula, spread the batter evenly into your prepared pan, smoothing the top. Pop the pan in the oven and bake for 22–25 minutes, just until the edges are set and the center appears slightly soft. This is key for getting that irresistible fudgy, chewy center.
Step 8: Cool and Slice
Let your Funfetti Blondies cool completely in the pan—patience here pays off with cleaner, more even squares. Once cool, use the parchment to lift them onto a cutting board, then slice into squares and admire your rainbow-spangled creations!
How to Serve Funfetti Blondies

Garnishes
For a little extra dazzle, sprinkle a few additional rainbow sprinkles or even a light dusting of powdered sugar over the top just before serving. If you’re feeling decadent, a tiny drizzle of white chocolate or a dollop of whipped cream will make your Funfetti Blondies even more festive.
Side Dishes
Funfetti Blondies pair beautifully with a cold glass of milk, a scoop of vanilla ice cream, or fresh berries. Their creamy, sweet profile is the perfect companion to coffee or a frothy latte for a pick-me-up treat any time of day.
Creative Ways to Present
Stack the blondie squares in a colorful tower, wrap them individually in wax paper as party favors, or use cookie cutters to shape them into hearts or stars for special occasions. Funfetti Blondies are picture-perfect for birthday trays, bake sales, or just because!
Make Ahead and Storage
Storing Leftovers
Keep your Funfetti Blondies soft and chewy by storing them in an airtight container at room temperature. They will stay fresh for up to 4 days, making them fabulous as a grab-and-go lunchbox treat or midnight snack.
Freezing
Yes, you can absolutely freeze Funfetti Blondies! Wrap individual squares tightly in plastic wrap and stash them in a freezer-safe bag. They’ll keep beautifully for up to 2 months—just thaw at room temperature when you’re ready for a colorful pick-me-up.
Reheating
For that fresh-baked magic, pop a blondie square in the microwave for 5 to 10 seconds. This revives the gooey white chocolate chips and brings back the just-baked softness. Be careful not to overheat, so the sprinkles don’t melt away!
FAQs
Can I use dark or white chocolate chips instead?
Absolutely! While white chocolate chips add a creamy touch, you can easily substitute dark or milk chocolate chips if you’d like a different flavor profile. Even butterscotch chips are an amazing twist for Funfetti Blondies.
What kind of sprinkles work best?
The classic rainbow “jimmies” (long, rod-shaped sprinkles) are ideal, as they hold their shape and color during baking. Nonpareils (tiny balls) can bleed into the batter, so stick with jimmies for that true Funfetti magic.
Can I double this recipe?
Yes! Simply double all of the ingredients and bake in a 9×13-inch pan. You may need to add an extra 5 minutes to the baking time, so keep an eye on the edges and the center’s softness.
Are Funfetti Blondies gluten-free?
This recipe uses all-purpose flour, but you can swap in your favorite 1-to-1 gluten-free baking blend. Just make sure any mix-ins, like white chocolate chips, are also gluten-free to ensure everyone can enjoy them.
Can I make these Funfetti Blondies vegan?
With a few swaps—like using vegan butter, a flax egg, and dairy-free chocolate chips—you can absolutely make plant-based Funfetti Blondies. The joy and vibrant color are 100 percent included.
Final Thoughts
If you’re searching for a treat that will light up both your taste buds and your day, give these Funfetti Blondies a whirl. Every chewy, sprinkle-packed square is loaded with good vibes and happiness. Go ahead—bake, share, and celebrate the little things with every vibrant bite!
