If you’re looking for an easy way to brighten up your favorite blondies, just add sprinkles. These chewy funfetti blondies are buttery, soft, and perfectly sweet — with colorful rainbow sprinkles folded right into the batter. They’re made in just one bowl and come together with simple pantry staples, making them perfect for birthdays, celebrations, or any day that needs a little extra joy.
Funfetti may technically just be vanilla with sprinkles, but there’s something nostalgic and irresistible about those pops of color in every bite.
What Are Funfetti Blondies?
Think of blondies as brownies’ golden sibling. They have the same chewy, fudgy texture, but instead of chocolate, they’re flavored with rich vanilla and butter.
Funfetti blondies take that classic vanilla base and mix in rainbow sprinkles for a festive twist. They’re:
- Soft and buttery
- Perfectly chewy
- Easy to make (no mixer required)
- A guaranteed crowd-pleaser
Sometimes you want brownies. Sometimes you want something just as indulgent — but brighter and more playful.
Ingredients You’ll Need
You only need 8 simple ingredients:
- Butter (melted)
- Granulated sugar
- 1 egg + 1 egg yolk
- Vanilla extract
- All-purpose flour
- Baking powder
- Salt
- Rainbow sprinkles
Because this recipe is simple, quality matters. Use good butter and pure vanilla extract — they provide most of the flavor in blondies.
How to Make Funfetti Blondies
1. Prep
Preheat oven to 350°F. Line an 8×8-inch pan with parchment paper.
2. Mix Wet Ingredients
In a large bowl, whisk together melted butter and sugar. Add the egg, egg yolk, and vanilla extract and mix until smooth.
3. Add Dry Ingredients
Stir together flour, baking powder, and salt in a separate bowl. Add to the wet ingredients and fold until just combined. Do not overmix.
4. Fold in Sprinkles
Gently fold in the rainbow sprinkles.
5. Bake
Spread the batter evenly in the prepared pan and bake for about 30 minutes, until the edges are set and lightly golden. The center may look slightly underdone — that’s perfect. They’ll continue to set as they cool.
Let cool completely before slicing into squares.
Tips for Perfect Blondies
Don’t overmix.
Overmixing develops gluten and makes blondies tough. Mix only until the flour disappears.
Use high-quality vanilla and butter.
Since there’s no chocolate, these flavors shine through.
Don’t overbake.
An overbaked blondie is dry and crumbly. Pull them out when the center still looks slightly soft.
Fun Ways to Customize
Blondies are a blank canvas. Try:
- Stirring in white chocolate chips
- Drizzling with a simple vanilla glaze
- Topping with buttercream frosting
- Serving warm with vanilla ice cream
And of course… more sprinkles never hurt.
These funfetti blondies are soft, chewy, buttery, and bursting with color. Whether you’re celebrating something special or just want a cheerful dessert, this one-bowl recipe makes it easy to bake up a little happiness.
