Ingredients
Detailed List of Ingredients
- 2 ½ cups all-purpose flour
- 1 teaspoon baking soda
- ½ teaspoon salt
- 1 cup unsalted butter, softened
- 1 cup granulated sugar
- ½ cup brown sugar, packed
- 2 large eggs, at room temperature
- 2 teaspoons pure vanilla extract
- ½ cup rainbow sprinkles (plus extra for topping)
- 1 cup white chocolate chips (optional)
When I make Funfetti Sugar Cookie Bars, I always start with fresh ingredients. Fresh butter and eggs really help the taste. The flour should be all-purpose. It's the best choice for soft and chewy bars. I love using both granulated and brown sugar. They give the bars a nice balance of sweetness and depth.
For that fun burst of color, rainbow sprinkles are key. Use half a cup in the dough and sprinkle more on top. This makes the bars look festive! If you're a fan of white chocolate, add the chips. They melt beautifully and add a rich flavor.
Measurement Tips
When measuring flour, spoon it into the cup and level it off. This helps avoid using too much. A kitchen scale can also help you get it just right, especially for baking. If you need gluten-free options, use a gluten-free flour blend. For vegan bars, swap eggs for flax eggs or applesauce.
Essential Tools Needed
- Mixing bowls
- Electric mixer or whisk
- Baking dish (9x13-inch)
- Spatula
Having the right tools makes baking easier. A good mixing bowl helps with combining ingredients. An electric mixer speeds up the creaming process, but a whisk works too. A 9x13-inch baking dish is perfect for these bars. A spatula is great for spreading the dough evenly. With these tools, you're all set to create these colorful treats!

Step-by-Step Instructions
Prepping the Ingredients
- Preheat the oven to 350°F (175°C).
- Prepare a 9x13-inch baking dish. Grease it with butter or line it with parchment paper.
Mixing the Dough
- In a bowl, whisk together 2 ½ cups all-purpose flour, 1 teaspoon baking soda, and ½ teaspoon salt.
- In another bowl, cream together 1 cup softened butter, 1 cup granulated sugar, and ½ cup packed brown sugar. Beat until it is light and fluffy.
- Add 2 large eggs, mixing after each one. Stir in 2 teaspoons of pure vanilla extract.
Finalizing the Cookie Dough
- Gradually mix the dry ingredients into the wet mixture until combined. Be careful not to overmix.
- Fold in ½ cup of rainbow sprinkles and 1 cup of white chocolate chips if you want. Ensure they are evenly mixed.
Baking the Bars
- Spread the dough evenly in the prepared baking dish. Add extra sprinkles on top if you like.
- Bake for 20-25 minutes. Check for doneness with a toothpick. It should come out clean.
- Let the bars cool in the pan for 10-15 minutes. Use the parchment paper to lift them out and cool completely on a wire rack.
Tips & Tricks
Baking Tips for Perfect Bars
- Avoiding overmixing: Mix the dough gently. Overmixing can make the bars tough.
- Temperature tips for optimal texture: Ensure all ingredients are at room temperature. Cold butter or eggs can lead to uneven baking.
Decorating Ideas
- Creative ways to top with sprinkles: After spreading the dough, add extra sprinkles on top. This gives a fun and colorful look.
- Serving suggestions with ice cream: Serve warm bars with a scoop of vanilla ice cream. The melt will add a nice touch.
Common Mistakes to Avoid
- Ensuring correct baking time: Check at 20 minutes. Bars should be golden on the edges and soft in the middle.
- Proper cooling methods: Let bars cool in the pan for a bit. Then transfer them to a wire rack to cool completely. This helps keep them soft and chewy.
Pro Tips
- Use Room Temperature Ingredients: Ensuring your butter and eggs are at room temperature will help create a smoother batter and result in a better texture for your cookie bars.
- Don’t Overmix: When combining the dry ingredients with the wet mixture, mix just until combined. Overmixing can lead to tough cookie bars.
- Check for Doneness: Since oven temperatures can vary, start checking your cookie bars a few minutes before the suggested baking time to avoid overbaking.
- Storage Tips: Store any leftover cookie bars in an airtight container at room temperature for up to a week for the best freshness.
Variations
Flavor Customizations
You can change the sprinkles to fit your taste. Try chocolate sprinkles for a rich twist. Rainbow sprinkles add color and fun. You can also add nuts or dried fruit. Chopped walnuts or dried cherries bring extra flavor and texture.
Dietary Modifications
If you need gluten-free options, swap all-purpose flour for a gluten-free blend. Make sure the blend has a good taste. For vegan adaptations, use plant-based butter and egg replacements. Flax eggs or applesauce work well to bind the mix.
Seasonal Variations
For holidays, use themed sprinkles. Red and green for Christmas or pastels for Easter look great. You can adjust the flavors too! Add peppermint extract for winter or citrus zest for summer. Each season brings new chances for tasty fun!
Storage Info
Best Storage Practices
Store your Funfetti Sugar Cookie Bars in an airtight container. This keeps them fresh longer. Use a container that fits the size of your bars well. I recommend glass or plastic containers with a tight seal. If you stack them, place parchment paper between layers to avoid sticking.
Freezing Options
You can freeze these cookie bars for later. First, let them cool completely. Then, wrap each bar in plastic wrap. Place the wrapped bars in a freezer-safe bag or container. They can last up to three months in the freezer. When you want to eat them, take out the desired amount. Let them thaw in the fridge overnight for the best taste.
Shelf Life of Cookie Bars
When stored at room temperature, these cookie bars last about 3-5 days. Keep them in a cool, dry place. If you store them in the fridge, they can last up to a week. The cold helps keep them moist and fresh. However, they may become a bit firmer after chilling. If you prefer them soft, let them sit at room temperature for a few minutes before eating.
FAQs
How can I make my Funfetti Sugar Cookie Bars chewy?
To make your Funfetti Sugar Cookie Bars chewy, use less flour. Measure flour correctly by spooning it into the cup and leveling it off. Overmeasuring flour can make your bars dry. Also, avoid overbaking. Keep an eye on them in the oven. Baking for the right time keeps them soft and chewy.
Can I substitute ingredients for allergies?
Yes, you can substitute ingredients for allergies. For a dairy-free option, use vegan butter or coconut oil. You can replace eggs with flax eggs or applesauce. If you need gluten-free bars, use a gluten-free flour blend. Just ensure the substitutes match the original recipe’s texture.
What’s the best way to cut cookie bars evenly?
To cut cookie bars evenly, let them cool completely. Use a sharp knife for clean cuts. You can score the top lightly before cutting to help guide your slices. For perfect squares, cut into rows and then cut those rows into squares.
Can I use a different type of chocolate chips?
Yes, you can use other chocolate chips. Dark chocolate, milk chocolate, or even peanut butter chips work well. The flavor will change, but that’s part of the fun! Choose your favorite to make the bars more unique.
How do I know when the cookie bars are done baking?
You know the cookie bars are done when the edges are golden. Insert a toothpick in the center; if it comes out clean or with a few crumbs, they are ready. Be careful not to overbake, as they will firm up while cooling.
