Ingredients
To make the best Funfetti Sugar Cookie Bars, you need a few key ingredients. Here is what you’ll need:
– 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
– 1 tablespoon vanilla extract
– 2 large eggs
– 1 cup sprinkles (jimmies recommended)
– ½ cup white chocolate chips (optional)
Each ingredient plays a vital role. The flour gives structure, while butter adds richness. Sugar makes them sweet, and brown sugar adds moisture. Baking soda helps the bars rise, and salt balances the sweetness. Vanilla adds flavor, and eggs bind everything together. Sprinkles bring that festive touch, while white chocolate chips add extra sweetness.
Using jimmies for sprinkles is key. They hold their shape during baking. You can skip the chocolate chips if you prefer a classic cookie flavor. This simple list keeps it fun and easy to make these bars.

Step-by-Step Instructions
Preheat and Prepare the Pan
First, set your oven temperature to 350°F (175°C). This step is key for even baking. Then, line a 9×13 inch baking pan with parchment paper. Make sure to leave some overhang. This makes it easy to lift out the cookie bars later.
Mixing the Dry Ingredients
In a medium bowl, combine 2 ½ cups of all-purpose flour, 1 teaspoon of baking soda, and ½ teaspoon of salt. Whisk them together until they blend well. Set this bowl aside for now. This mix gives your cookie bars a nice rise.
Creaming the Butter and Sugars
In a large bowl, mix 1 cup of softened unsalted butter with 1 cup of granulated sugar and ½ cup of packed brown sugar. Use an electric mixer for about 2-3 minutes. You want the mixture to be light and fluffy. This step adds air, making your bars soft.
Incorporating Wet Ingredients
Next, add 1 tablespoon of vanilla extract and 2 large eggs to the creamed mixture. Beat everything until well combined. The eggs help bind the ingredients together, creating a smooth texture.
Combining Mixtures
Now, gently fold in the dry ingredients. Do this until just combined. Be careful not to over-mix. Then, add in 1 cup of sprinkles and ½ cup of white chocolate chips, if you choose. Fold these in carefully so they spread evenly.
Baking the Cookie Bars
Spread the dough evenly in the prepared pan. Smooth the top with a spatula. Bake in your preheated oven for 20-25 minutes. They are done when the edges are golden brown. You can check doneness by inserting a toothpick into the center. If it comes out clean, they are ready! Let the cookie bars cool in the pan for about 15 minutes. Then, lift them out using the parchment paper and let them cool completely on a wire rack. After cooling, cut into squares or rectangles and serve!
Tips & Tricks
Achieving the Perfect Texture
To avoid over-mixing, mix just until you see no dry flour. Over-mixing makes the bars tough. It’s all about the gentle touch. Once you add the dry ingredients, use a spatula to fold them in slowly. This keeps the cookie bars soft and chewy.
Best Baking Practices
Check for doneness by looking at the edges. They should be golden brown. Insert a toothpick in the center; it should come out clean. Once done, let the bars cool in the pan for 15 minutes. This helps them set up before moving them. Use parchment paper to lift them out easily. After that, cool them completely on a wire rack.
Enhancing Flavor Options
Want to boost flavor? Try adding a dash of almond extract. It adds a nice twist. You can also mix in nuts or different types of chips. Dark chocolate or peanut butter chips work great. These simple changes can make your Funfetti bars even more fun!
Pro Tips
- Use Room Temperature Butter: Softened butter helps achieve a creamy texture, which is essential for fluffy cookie bars.
- Don’t Overmix the Dough: Mix just until the flour is incorporated to keep the bars tender and chewy.
- Choose the Right Sprinkles: Jimmies are best for baking as they hold their shape and color better than nonpareils.
- Cool Completely Before Cutting: Allowing the bars to cool fully prevents them from crumbling when you cut them.

Variations
Funfetti Theme Ideas
Funfetti sugar cookie bars fit many fun themes. You can use them for birthdays, holidays, or parties. Change the sprinkles to match the theme. For a birthday, use bright colors. For holidays, pick red and green or pastel colors. These cookie bars can brighten any event.
Alternative Add-ins
You can customize your bars with different mix-ins. Instead of white chocolate chips, try dark chocolate or milk chocolate chips. You can also add chopped nuts like walnuts or pecans for crunch. Another tasty option is to mix in peanut butter chips or caramel bits. Each choice gives a new flavor twist.
Dietary Adjustments
If you need gluten-free bars, swap all-purpose flour for gluten-free flour. Make sure it’s a blend that works for baking. For a dairy-free option, use vegan butter and dairy-free chocolate chips. These swaps will keep the bars tasty while meeting dietary needs. Enjoy the same joy with different choices!
Storage Info
Best Storage Practices
Store your Funfetti sugar cookie bars in an airtight container. This keeps them fresh and soft. Place parchment paper between layers to avoid sticking. Keep the container in a cool, dry place, away from sunlight. If you want to enjoy them longer, refrigerate the bars. They stay fresh and tasty in the fridge.
Freezing Instructions
To freeze cookie bars, first, let them cool completely. Then, cut them into squares. Wrap each piece tightly in plastic wrap. Place the wrapped bars in a freezer-safe bag. Squeeze out any extra air before sealing. To thaw, take them out of the freezer and let them sit at room temperature for about 30 minutes. Enjoy your thawed treat!
Shelf Life
When stored at room temperature, these cookie bars last about 3 to 5 days. If you store them in the fridge, they can stay fresh for up to a week. Freezing extends their life to about 3 months. Just make sure they are well-wrapped to prevent freezer burn.
FAQs
Can I use cold butter instead of softened?
No, you should not use cold butter. Softened butter mixes better with sugars. It helps to create air pockets, making your cookie bars light and soft. Cold butter does not blend well, leading to dense bars. Always let your butter sit out for about 30 minutes. This will make it easy to cream with the sugars.
What can I substitute for eggs?
If you need an egg substitute, you have options. You can use unsweetened applesauce. Use 1/4 cup of applesauce for each egg. You can also use mashed banana, with the same ratio. Another option is flaxseed meal. Mix 1 tablespoon of flaxseed meal with 2.5 tablespoons of water. Let it sit for five minutes, and it becomes gel-like. Each of these choices works well in the recipe.
How do I make these without sprinkles?
If you want to skip the sprinkles, you can use chocolate chips instead. White chocolate chips or milk chocolate chips add a nice touch. You can also fold in nuts like walnuts or pecans. If you want to keep it simple, just leave them out. The bars will still taste great without sprinkles.
Can I double the recipe?
Yes, you can double the recipe! Just use a larger pan, like a 12×18 inch pan. Make sure to adjust the baking time. Check for doneness a few minutes earlier, as larger batches can cook differently. More cookie bars mean more fun, so feel free to share!
