How to Prepare Funfetti Blondies Recipe

Get your oven preheated, and let’s dive into the step-by-step process to make these incredible Funfetti Blondies!
Step 1: Preheat the Oven
Preheat your oven to 350°F (175°C) and line your baking pan with parchment paper for easy removal.
Step 2: Mix the Wet Ingredients
In a large mixing bowl, whisk together the melted butter, dark brown sugar, and granulated sugar until well combined. Add the egg and vanilla extract, and mix until smooth and creamy.
Step 3: Combine the Dry Ingredients
In another bowl, whisk together the all-purpose flour, baking powder, and kosher salt.
Step 4: Combine Wet and Dry Ingredients
Gradually add the dry ingredients to the wet ingredients, stirring until just combined. Be careful not to overmix, as this can lead to tough blondies.
Step 5: Fold in the Sprinkles
Gently fold in the sprinkles, ensuring they are evenly distributed throughout the batter.
Step 6: Bake the Blondies
Pour the batter into the prepared baking pan and spread it out evenly. Bake for 20-25 minutes, or until the edges are golden brown and a toothpick inserted in the center comes out with a few moist crumbs.
Step 7: Cool and Serve
Allow the blondies to cool in the pan for about 10 minutes before transferring them to a wire rack to cool completely. Once cool, cut them into squares and enjoy!
Year-Round Variations

These Funfetti Blondies can be adapted for different occasions and seasons:
- Holiday Themes: Use themed sprinkles for holidays like red and green for Christmas or pastel colors for Easter.

- Frosted Fun: Top with a simple vanilla frosting for an extra indulgent treat.
Easy-to-Miss Gotchas
When making these Funfetti Blondies, keep these tips in mind:
- Be sure the butter is cooled before mixing it with the sugars; hot butter can cook the egg.
- Don’t overmix the batter; this will ensure your blondies remain soft and chewy.
- Check for doneness a few minutes before the baking time is up; ovens vary in temperature.
- Allow cooling time before cutting to ensure clean edges and prevent crumbling.
Freezer-Friendly Notes
These Funfetti Blondies are great for making ahead of time!
- Once cooled, wrap the blondies tightly in plastic wrap or foil, then place them in an airtight container.
- They can be frozen for up to three months. To enjoy, simply thaw at room temperature.
- For an extra treat, warm them in the microwave for a few seconds before serving!
Top Questions & Answers
Can I use different types of sugar?
Yes! You can substitute light brown sugar for dark brown sugar, but this may slightly alter the flavor. Granulated sugar is essential for sweetness and texture.
What can I substitute for butter?
If you’re looking for a dairy-free option, you can use melted coconut oil or a vegan butter substitute, though the flavor will change slightly.
How do I store leftovers?
Store leftover blondies in an airtight container at room temperature for up to five days or in the refrigerator for up to a week.
Can I double the recipe?
Absolutely! To double the recipe, simply double each ingredient and use a larger baking pan. Adjust the baking time as necessary, checking for doneness.
