Why You'll Love Funfetti Blondies
Chewy blondie texture: These bake up dense and soft in the center rather than light like cake.
Even sprinkle distribution: The sprinkles stay mixed throughout the bars instead of sinking or bleeding.
White chocolate balance: White chocolate adds sweetness without overpowering the vanilla base.
One-pan baking: Everything bakes in a single 8×8 pan, which keeps prep and cleanup simple.
Good for sharing: The bars hold together well and are easy to portion for parties or casual desserts.
Key ingredients
- Butter: Melted butter gives the blondies their rich flavor and chewy texture without needing a mixer.
- Eggs: Help bind the batter and give the bars structure while keeping the center soft.
- Granulated sugar: Sweetens the blondies and contributes to their dense, classic blondie texture.
- White chocolate chips: Add pockets of sweetness that pair well with the vanilla base.
- Rainbow sprinkles: Provide color and a light crunch; jimmies-style sprinkles work best to prevent bleeding.

Easy Substitutions & Variations
- Brown sugar swap: Replace half of the granulated sugar with brown sugar for a slightly deeper flavor and softer texture.
- Sprinkle choice: Jimmies work best, but if using nonpareils, fold them in quickly to reduce color bleeding.
- Chip swap: Milk chocolate or semi-sweet chocolate chips can be used instead of white chocolate if preferred.
- Pan size: Bake in a 9×9 pan for slightly thinner blondies and reduce the bake time by a few minutes.
- Flavor add-in: A small splash of almond extract can be added for a subtle bakery-style flavor.
How to Make Funfetti Blondies
- Step 1: Preheat the oven to 350°F and grease an 8×8 baking pan. In a large bowl, beat the melted butter, eggs, and vanilla extract.
- Step 2: Add the flour, granulated sugar, salt, and baking powder, mixing just until incorporated.
- Step 3: Fold in the white chocolate chips and rainbow sprinkles, being careful not to over mix. Spread the batter evenly into the prepared pan.
- Step 4: Bake for about 25 minutes, until the edges are set. Let the blondies cool completely before slicing and serving.
Recipe Notes & Tips
- Do not over bake: Funfetti blondies are best when the center is just set; over baking will make them dry instead of chewy.
- Use jimmies-style sprinkles: Jimmies hold their color better and won't streak the batter as it bakes.
- Mix gently: Overmixing once the flour is added can make the blondies tough rather than soft.
- Check the center: The edges should be set while the middle still looks slightly soft when you pull them from the oven.
- Let them cool fully: Cooling allows the bars to firm up and develop their final texture before serving.
Make-Ahead & Freezing Options
- Make ahead: Funfetti blondies can be baked a day in advance and stored covered at room temperature once fully cooled.
- Short-term storage: Keep leftovers in an airtight container at room temperature for up to 2 days or refrigerate for up to 4 days.
- Freeze the blondies: Wrap the fully cooled bars tightly or store in a freezer-safe container for up to 2 months.
- Freeze individual portions: Slice the blondies first, then freeze pieces separately for easy thawing.
- Thawing tips: Thaw at room temperature until softened before serving.
Funfetti Blondies faqs
Funfetti blondies turn dry when they're over baked or when too much flour is added. Pulling them from the oven when the center is just set helps keep the texture soft and chewy.
Using jimmies-style sprinkles instead of nonpareils helps prevent color bleeding in funfetti blondies. Folding them in gently at the end also reduces streaking.
Funfetti blondies are done when the edges are set and lightly golden and the center looks just set, not glossy or raw. A toothpick inserted should come out with moist crumbs, not wet batter.
