To bake Funfetti Sugar Cookie Bars, you need these simple ingredients. First, use all-purpose flour for the base. Baking powder and baking soda help the bars rise. A touch of salt balances the sweetness.

Step-by-Step Instructions
Preparing the Baking Pan
Start by preheating your oven to 350°F (175°C). This step is key to ensure even baking. Next, take a 9x13-inch baking pan. You can grease it lightly with butter or spray. Alternatively, line it with parchment paper. This makes it easy to remove the bars later.
Mixing the Dry Ingredients
In a medium bowl, measure out the flour, baking powder, baking soda, and salt. Whisk them together until they mix well. This helps the leavening agents spread evenly in your dough. Set this bowl aside for later.
Creaming the Butter and Sugars
In a large bowl, add the softened butter, granulated sugar, and brown sugar. Using an electric mixer, beat these together. Mix on medium speed for about 2-3 minutes. You want it to become light and fluffy. This step adds air, making your bars soft.
Adding Eggs and Vanilla
Now, add the eggs one at a time. Beat well after each egg. This ensures they blend in fully. Then, pour in the vanilla extract. Mixing it in adds a lovely flavor and aroma to your batter.
Combining Wet and Dry Ingredients
Gradually add the dry mixture to the wet ingredients. Do this in batches for the best results. Mix on low speed until just combined. Be careful not to overmix. This keeps the texture tender and light.
Adding Funfetti Touches
Next, gently fold in the rainbow sprinkles and white chocolate chips with a spatula. Make sure they are evenly spread throughout the batter. This folding method keeps the sprinkles intact and adds that signature funfetti look.
Baking Process
Pour the cookie batter into your prepared pan. Spread it out evenly with a spatula. For a festive touch, sprinkle some extra rainbow sprinkles on top. Place the pan in the preheated oven and bake for 25-30 minutes. The edges should turn golden brown, and the center will be set but may jiggle a bit.
Cooling and Serving
Once baked, remove the pan from the oven. Let the bars cool in the pan on a wire rack for at least 30 minutes. This cooling time helps them firm up. After cooling, slice them into squares for serving. Enjoy these delightful treats with friends or family!
Tips & Tricks
Achieving the Perfect Texture
To get the best texture in your Funfetti sugar cookie bars, it is key not to overmix. Overmixing can make the bars tough. Mix just until the flour disappears. This keeps them soft and chewy.
For accurate ingredient measurements, I recommend using a kitchen scale. Weighing ingredients gives you the best results. If you don’t have one, use dry measuring cups. Level off the flour with a knife for an accurate measure.
Enhancing Flavor and Presentation
You can elevate the look of these cookie bars with some fun toppings. Try adding a drizzle of melted white chocolate on top. You can also sprinkle extra rainbow sprinkles for a pop of color.
For serving, place the bars on a bright platter. This adds to their festive vibe. You can garnish each slice with a few sprinkles. It makes each piece look even more inviting.
Baking Time Adjustments
To check for doneness, look at the edges. They should be golden brown. The center can have a slight jiggle; that’s fine. It will set as the bars cool.
Ovens can vary, so keep an eye on your bars. If your oven runs hot, check them a few minutes early. Adjust the baking time as needed for your specific oven. This ensures you get perfect cookie bars every time.
Pro Tips
- Use Room Temperature Ingredients: Make sure your butter and eggs are at room temperature for better incorporation, leading to a smoother batter and more tender cookie bars.
- Don't Overmix: When combining the dry ingredients with the wet, mix just until combined. Overmixing can result in tougher bars due to gluten development.
- Customize Your Sprinkles: Feel free to use different types of sprinkles, such as star-shaped or seasonal colors, to match the occasion and add a personal touch.
- Check for Doneness: Since ovens can vary, start checking for doneness a few minutes before the suggested baking time. The edges should be golden brown while the center may still have a slight jiggle.
Variations
Gluten-Free Funfetti Sugar Cookie Bars
If you want to make gluten-free funfetti bars, you can use different flours. Almond flour or a gluten-free all-purpose blend works well. You might also try oat flour for a unique taste. When baking gluten-free, you often need to add a binding agent like xanthan gum. This helps hold your bars together. Always check your flour mix for the best results.
Vegan Funfetti Sugar Cookie Bars
To make these bars vegan, you can swap out the eggs. Use flax eggs or applesauce as a great substitute. For each egg, mix one tablespoon of ground flaxseed with two and a half tablespoons of water. Let it sit until it thickens. For the butter, use dairy-free options like coconut oil or vegan butter. Make sure to choose vegan-friendly sugar too.
Flavor Variations
You can make these bars even more fun by adding flavors. Try mixing in almond or coconut extract for a twist. You can also change up the mix-ins. Swap white chocolate chips for dark or milk chocolate chips. Adding nuts like walnuts or pecans can give your bars a nice crunch. Don't be afraid to get creative with your ingredients!
Storage Info
Best Storage Practices
Store your Funfetti sugar cookie bars at room temperature. They stay soft and tasty this way. Use an airtight container to keep them fresh. A container with a tight seal works best. You can also place parchment paper between layers to avoid sticking.
Freezing Instructions
To freeze your cookie bars, let them cool completely. Then, cut them into squares. Wrap each piece in plastic wrap. Place the wrapped bars in a freezer-safe bag or container. This keeps them safe from freezer burn. To thaw, take them out and let them sit at room temperature. You can also warm them in a microwave for a few seconds to regain softness.
Shelf Life
These cookie bars last about a week at room temperature. If you freeze them, they can last up to three months. Watch for signs of spoilage. If they smell off or have a hard texture, it’s best to toss them. Enjoy your sweet treats while they are fresh!
FAQs
Can I use different types of sprinkles?
Yes, you can use many sprinkle types! Try chocolate sprinkles for a twist. You can also use star shapes or hearts for fun themes. Keep in mind that darker sprinkles may color the dough. Choose bright colors for a cheerful look.
How do I make sure my cookie bars are chewy?
To keep your bars chewy, do not overmix the dough. Mix until just combined. Use fresh ingredients for the best texture. Also, avoid overbaking; a slight jiggle in the center is okay. Let them cool in the pan to maintain moisture.
Can I halve the recipe?
Yes, you can easily halve the recipe. Use 1 ⅜ cups of flour and adjust other ingredients. Bake in a smaller pan, like an 8x8-inch, for about 20-25 minutes. Keep an eye on them to prevent overbaking.
What's the best way to cut the cookie bars?
To cut your cookie bars cleanly, let them cool completely. Use a sharp knife for straight cuts. Wipe the knife with a damp cloth between cuts to prevent crumbling. This keeps the edges neat and tidy.
How to fix over-baked cookie bars?
If your cookie bars are dry, try adding a glaze or frosting. This adds moisture and flavor. You can also serve them with ice cream or whipped cream. For next time, check for doneness earlier to avoid overbaking.
You now know how to make perfect Funfetti Sugar Cookie Bars. From gathering ingredients to mixing and baking, each step is crucial. Remember to measure carefully and not overmix for the best texture.
