Ingredients
List of Ingredients
- 1 cup unsalted butter (melted)
- 1 cup brown sugar (packed)
- 1/2 cup granulated sugar
- 2 large eggs
- 2 teaspoons vanilla extract
- 2 cups all-purpose flour
- 1 teaspoon baking powder
- 1/2 teaspoon salt
- 1/2 cup rainbow sprinkles (plus more for topping)
- 1/2 cup white chocolate chips (optional)
To make funfetti blondies, gather these simple ingredients. Start with a cup of unsalted butter. Melt it down to bring out its rich flavor. You’ll need both brown sugar and granulated sugar for sweetness. Use a cup of brown sugar, packed tight, and half a cup of granulated sugar.
Next, crack in two large eggs. These will help bind the mix. Add two teaspoons of vanilla extract for a lovely aroma.
Now, let’s get to the dry ingredients. Measure out two cups of all-purpose flour. This forms the base of your blondies. Sprinkle in one teaspoon of baking powder to help them rise. Don’t forget half a teaspoon of salt to balance the sweetness.
Finally, it’s time for the fun part! Add half a cup of rainbow sprinkles for color and joy. You can also toss in half a cup of white chocolate chips if you like a creamy touch. This mix of flavors will create a delicious treat that everyone loves!

Step-by-Step Instructions
Preheating and Preparing the Pan
First, set your oven to 350°F (175°C). This helps the blondies bake evenly. Next, take a 9x13 inch baking dish and grease it. You can also line it with parchment paper for easy removal later.
Mixing the Wet Ingredients
In a large bowl, combine 1 cup of melted unsalted butter, 1 cup of packed brown sugar, and 1/2 cup of granulated sugar. Mix these well until the mixture is smooth. Now, add 2 large eggs, one at a time. Make sure to stir well after each egg. Finally, add 2 teaspoons of vanilla extract. This will give your blondies a lovely flavor.
Combining Dry Ingredients
In another bowl, whisk together 2 cups of all-purpose flour, 1 teaspoon of baking powder, and 1/2 teaspoon of salt. This step ensures even mixing of the dry ingredients. Gradually add this dry mix to your wet ingredients. Stir just until everything is combined. Don't overmix, or your blondies may become tough.
Folding in Sprinkles and Chips
Now comes the fun part! Gently fold in 1/2 cup of rainbow sprinkles and 1/2 cup of white chocolate chips if you like them. Use a spatula to mix until the sprinkles and chips are evenly spread throughout the batter.
Baking Procedure
Pour the batter into your prepared baking dish. Spread it out evenly with a spatula. For a fun touch, sprinkle a few extra rainbow sprinkles on top. Bake in the oven for 20-25 minutes. To check if they are done, insert a toothpick in the center. It should come out with a few moist crumbs.
Cooling and Serving
Let the blondies cool in the dish for at least 10 minutes. Then, transfer them to a wire rack to cool completely. Once cool, cut them into squares or bars. Now, you're ready to enjoy these sweet treats!
Tips & Tricks
Storage Tips for Funfetti Blondies
Store your Funfetti Blondies in an airtight container. They stay fresh for up to a week. If you want to keep them longer, freeze them. Wrap each bar tightly in plastic wrap. Then place them in a freezer-safe bag. They will stay good for about three months.
Tips for Perfectly Soft Blondies
To get soft blondies, do not overmix the batter. Mix just until the flour disappears. Also, do not bake them too long. A toothpick should come out with a few moist crumbs. Let them cool in the pan for a bit before slicing. This helps keep them soft and chewy.
Common Mistakes to Avoid
One common mistake is using cold butter. Always melt it first for the best texture. Another mistake is not measuring the flour correctly. Too much flour can make the blondies dry. Finally, don’t skip the sprinkles; they add fun and color.
Pro Tips
- Check for Doneness: Insert a toothpick into the center; it should come out with a few moist crumbs for perfectly baked blondies.
- Storage Tips: Store blondies in an airtight container at room temperature for up to a week or refrigerate for longer freshness.
- Customize Your Mix-ins: Feel free to swap in your favorite mix-ins like nuts or different types of chocolate for a unique twist.
- Let Them Cool: Allow blondies to cool completely before cutting to ensure clean edges and prevent them from falling apart.
Variations
Funfetti Blondies with Nut Additions
You can make funfetti blondies even better with nuts. Try adding chopped walnuts or pecans. Nuts add a nice crunch and flavor. Use about 1/2 cup of nuts. Mix them in when you fold in the sprinkles. This gives your blondies a tasty twist.
Gluten-Free Funfetti Blondies
If you need gluten-free blondies, swap the all-purpose flour. Use a gluten-free flour blend instead. Make sure the blend has a good mix of starches. This keeps the texture soft and chewy. Follow the same steps in the recipe. Your blondies will still be fun and colorful!
Vegan Funfetti Blondies
To make vegan funfetti blondies, replace the eggs. Use flaxseed meal mixed with water instead. Mix 1 tablespoon flaxseed meal with 2.5 tablespoons water. Let it sit for five minutes to thicken. Also, swap the butter for coconut oil or vegan butter. This keeps the blondies moist and delicious.

Best Storage Methods
To keep your Funfetti Blondies fresh, store them in an airtight container. This helps prevent them from drying out. You can place parchment paper between layers to avoid sticking. Keep the container at room temperature for up to 3 days. If you want them to last longer, consider refrigeration. This extends their life to about a week. However, they may lose some of their soft texture when cold.
Freezing Funfetti Blondies
You can freeze Funfetti Blondies for later enjoyment. First, let them cool completely. Then, cut them into squares. Wrap each piece tightly in plastic wrap. After that, place the wrapped pieces in a freezer-safe bag. Remove as much air as possible. They can stay in the freezer for up to 3 months. When you're ready to eat, just thaw them at room temperature.
Reheating Instructions
Reheating Funfetti Blondies is simple. To enjoy them warm, preheat your oven to 350°F (175°C). Place the blondies on a baking sheet. Heat them for about 5 to 10 minutes. You can also microwave them for about 10-15 seconds. Be careful not to overheat them, or they may dry out. Enjoy them warm for a gooey treat!
FAQs
Can I use different types of sprinkles?
Yes, you can use different sprinkles. I often try chocolate sprinkles or heart-shaped ones. Each type adds a new look and taste. Just make sure they are safe for baking. Some sprinkles melt, while others hold their shape.
What can I substitute for eggs?
You can replace eggs with applesauce or mashed bananas. Use 1/4 cup for each egg. This keeps your blondies moist and sweet. You can also try flaxseed meal. Mix 1 tablespoon of flaxseed with 2.5 tablespoons of water. Let it sit for a few minutes to thicken.
How do I know when blondies are done baking?
Check for a toothpick test. Insert a toothpick in the center. If it comes out with a few moist crumbs, they are ready. The top should look set and slightly golden. Don’t overbake them. They should stay soft and chewy.
Can I make these blondies in advance?
Yes, you can make them ahead of time. They stay fresh for a few days at room temperature. Just cover them well to keep them soft. You can also freeze them. Cut into squares and wrap them in plastic. They last for up to three months in the freezer.
