Step‑by‑Step Instructions for Funfetti Blondies
Step 1: Preheat the Oven
Begin by preheating your oven to 350°F (175°C). As it warms, prepare an 8×8 inch baking pan by lining it with parchment paper, or lightly spraying it with non-stick cooking spray. This ensures your delicious Funfetti Blondies will release easily after baking, preserving their chewy texture and vibrant colors.
Step 2: Whisk Together the Egg and Sugars
In a large mixing bowl, combine the large egg, granulated sugar, and brown sugar. Using a handheld mixer set to medium-high speed, whisk the mixture for about 3-4 minutes, until it becomes pale and glossy. This step is crucial for achieving that signature crackly top on your Funfetti Blondies, so mix well!
Step 3: Melt the Butter and Add Vanilla
Melt the unsalted butter in a microwave-safe bowl. Heat it in 30-second intervals until fully melted, then let it cool slightly. Once cooled, stir in the vanilla extract until combined. This fragrant mixture introduces depth of flavor that will complement the sweetness of your blondies beautifully.
Step 4: Combine Wet and Dry Ingredients
With the mixer still on low speed, slowly pour the butter and vanilla mixture into the egg and sugar mixture. Gradually whisk until just combined, then increase the speed to medium-high for an additional 10 seconds. This integration of wet ingredients is essential for achieving the fudgy texture of your Funfetti Blondies.
Step 5: Fold in Dry Ingredients and Sprinkles
Using a spatula, gently fold in the all-purpose flour, cornstarch, salt, and colorful sprinkles. Be careful not to overmix; you want the batter to be just combined for that perfect chewy contrast. The sprinkles will be suspended beautifully in the batter, ready to add a pop of color when baked.
Step 6: Spread the Batter in the Pan
Pour the batter into your prepared 8×8 inch pan, spreading it evenly with a spatula. This uniform layer helps each Funfetti Blondie bake consistently, ensuring a delightful chewy center and slightly crisp edges. Smooth out any lumps, making sure the sprinkles are evenly distributed throughout.
Step 7: Bake to Perfection
Place the pan in your preheated oven and bake for 23-25 minutes. You’ll know they’re done when the edges are lightly golden, and a toothpick inserted in the center comes out with moist crumbs. It’s important to keep an eye on them, as overbaking can reduce that fudgy goodness.
Step 8: Cool and Serve
Once baked, take your fun Funfetti Blondies out of the oven and let them cool in the pan for about 15 minutes. Then, carefully transfer them to a wire rack to cool completely before cutting. After they cool, slice them into squares and enjoy the colorful, chewy delights that are sure to brighten your day!

How to Store and Freeze Funfetti Blondies
Room Temperature: Store your Funfetti Blondies in an airtight container at room temperature for up to 3 days. This keeps them soft and chewy, ready for snacking!
Fridge: For extended freshness, you can refrigerate the blondies in an airtight container for up to one week. Just allow them to come to room temperature before serving.
Freezer: To enjoy these treats later, wrap individual blondies tightly in plastic wrap and freeze for up to 3 months. Thaw them overnight in the fridge before enjoying!
Reheating: If you prefer a warm treat, microwave a chilled blondie for about 10-15 seconds. This will revive their fudgy texture, making them even more delightful!

Funfetti Blondies Recipe FAQs
How do I choose the right ripeness of ingredients?
Absolutely! For the best Funfetti Blondies, use fresh ingredients. A large egg should be at room temperature, which improves the mixing process. Check your butter; it should be soft but not melted for optimal blending. If you notice dark spots on your egg, it may be overripe, so it’s best to choose a fresher one.
What’s the best way to store Funfetti Blondies?
To keep your Funfetti Blondies at their best, store them in an airtight container at room temperature for up to 3 days. This ensures they maintain their delightful softness and chewy texture. If you want to enjoy them longer, refrigerate them in an airtight container for about a week.
How can I freeze Funfetti Blondies?
Very easy! To freeze your Funfetti Blondies, wrap each individual piece tightly in plastic wrap and place them in a freezer-safe bag. They will stay fresh for up to 3 months. When you’re ready to enjoy them, simply thaw overnight in the fridge or let them sit at room temperature for a few hours.
What if my blondies come out too dense?
If your blondies turn out denser than expected, it might be due to overmixing the flour into the batter or using too much flour. Make sure you measure accurately, especially if using a kitchen scale, and fold the dry ingredients gently to maintain that light chewy texture. Remember, we want to keep it fun and enjoyable!
Are there any dietary considerations for Funfetti Blondies?
Absolutely! If you need a vegan option, swap the egg with a chia egg (1 tablespoon chia seeds mixed with 2.5 tablespoons water, let it sit to thicken) and use margarine or coconut oil instead of butter. For those with gluten sensitivities, a gluten-free flour blend can replace all-purpose flour without sacrificing taste. Just remember to check your sprinkles for any allergens!
Can I use different types of sugar?
Very much so! While granulated and brown sugar create the ideal sweetness and texture in Funfetti Blondies, feel free to experiment. For a healthier twist, coconut sugar is a great substitute, though it may slightly alter the taste and color. Always remember: the more the merrier when it comes to sweetness!
