Step‑by‑Step Instructions for Funfetti Blondies
Step 1: Preheat and Prepare Pan
Begin by preheating your oven to 350°F (175°C). Line an 8×8 inch baking pan with parchment paper, allowing some to overhang for easy removal later, or lightly spray the pan with cooking spray. This preparation ensures minimal sticking and helps you achieve those beautiful Funfetti Blondies without any fuss.
Step 2: Whisk Eggs and Sugars
In a medium mixing bowl, add the large egg along with both the granulated and brown sugars. Using a hand mixer, whisk on medium-high speed for 3-4 minutes until the mixture becomes pale and glossy—this will add air and create the signature chewy texture of your Funfetti Blondies.
Step 3: Melt Butter and Mix in Vanilla
Next, melt the unsalted butter in a microwave-safe bowl until just melted, which should take about 30 seconds. Remove it from the microwave and stir in the vanilla extract, allowing the buttery aroma to fill your kitchen. Ensure the butter isn’t too hot to avoid cooking the egg mixture in the next step.
Step 4: Combine Butter with Egg Mixture
Gradually pour the melted butter mixture into the egg and sugar mix while whisking at low speed. Once combined, increase the speed to medium-high and mix for an additional 10 seconds, ensuring everything is well integrated and that your Funfetti Blondies have a rich flavor base.
Step 5: Add Dry Ingredients and Fold in Sprinkles
Now, gently fold in the all-purpose flour, cornstarch, and salt using a spatula until just combined. Be careful not to overmix; some streaks of flour are perfectly fine. Finally, add in the colorful sprinkles, folding them until evenly distributed throughout the batter to bring that festive touch to your blondies.
Step 6: Spread Batter in the Pan
Carefully pour the batter into your prepared baking pan, using a spatula to spread it out evenly. Ensure the top is smooth and even for consistent baking. This step is vital for achieving those beautiful Funfetti Blondies with the perfect chewy texture in each delicious square.
Step 7: Bake to Perfection
Place the pan in the preheated oven and bake for 23-25 minutes. To check for doneness, insert a toothpick in the center—the goal is to see moist crumbs clinging to the toothpick, indicating your Funfetti Blondies are perfectly fudgy and not overbaked.
Step 8: Cool and Cut Blondies
Once baked, remove the pan from the oven and set it aside to cool for 15 minutes. After this initial cooling, lift the blondies out using the parchment paper overhang and transfer them to a wire rack. Allow them to cool completely before cutting into squares, ready to share these delightful Funfetti Blondies with friends and family!

Expert Tips for Funfetti Blondies
-
Whisk with Care: Whisking eggs and sugars vigorously is essential for achieving that light, crinkly top characteristic of blondies.
-
Butter Temperature Matters: Make sure the melted butter is warm, not hot. Hot butter can cook the egg mixture, affecting the final texture.

Precise Measurements: Use a kitchen scale for measuring flour; improper flour measurements can lead to denser blondies.
-
Avoid Overbaking: Check for doneness a bit early; moist crumbs on a toothpick indicate the perfect fudgy texture in your Funfetti Blondies.
-
Don’t Skip the Salt: A pinch of salt enhances the sweetness and balances out the flavors, preventing the blondies from tasting overly sweet.
-
Cool Before Cutting: Let the blondies cool completely before cutting to ensure clean, neat squares that are perfect for sharing!

Funfetti Blondies Recipe FAQs
Can I use different types of flour?
Absolutely! You can substitute all-purpose flour with a gluten-free flour blend if needed. Just ensure that the blend you choose contains a starch to maintain the soft texture. I often recommend almond flour for a nutty flavor that complements the sweetness beautifully!
How long can I store Funfetti Blondies?
Keep your Funfetti Blondies in an airtight container at room temperature for about 3 days. For even longer storage, refrigerate them, which will keep them fresh for up to 7 days. They’ll stay delicious and chewy, just ready to be enjoyed!
Can I freeze these blondies?
Yes, you can freeze Funfetti Blondies! To do so, wrap each blondie individually in plastic wrap and then place them in a zip-top bag. They can stay in the freezer for up to 2 months. When you’re ready to enjoy, let them thaw at room temperature for about 30 minutes, then if desired, pop them in the microwave for 10-15 seconds for a warm treat.
What should I do if my blondies turn out too dense?
If your blondies are denser than expected, it’s usually due to overmixing the batter or using too much flour. When you fold in the dry ingredients, be gentle and stop mixing as soon as no streaks of flour are visible. It’s better to leave a few light streaks than to overmix! Consider using a kitchen scale for accurate measurements to avoid this in the future.
Are there any allergy considerations with this recipe?
Yes, if you have allergies, you might want to avoid certain ingredients. The recipe uses eggs and butter, which could be a concern for those with dairy or egg allergies. I recommend using a flax egg as a vegan alternative and substituting with melted coconut oil for a dairy-free option. Always double-check with your guests regarding dietary restrictions before serving!
Can I make these blondies more colorful?
Absolutely! To elevate their festive appearance, you can use different colors of sprinkles to match any celebration theme. Alternatively, consider incorporating different mix-ins like mini chocolate chips or crushed candies for added fun and texture!
