Step-by-Step Instructions
Preheat and Prepare the Baking Pan
Start by setting your oven to 350°F (175°C). Take a 9×13-inch baking pan and grease it with butter or cooking spray. Line the pan with parchment paper, leaving some overhang. This makes it easy to lift out the cookie bars later.
Mixing Dry Ingredients
In a medium bowl, whisk together 2 ½ cups of all-purpose flour, 1 teaspoon of baking powder, ½ teaspoon of baking soda, and ½ teaspoon of salt. Mix these well and set the bowl aside for later.
Creaming Butter and Sugars
In a large bowl, add 1 cup of softened unsalted butter. Then, add 1 cup of granulated sugar and ¾ cup of packed light brown sugar. Use a mixer on medium speed to cream these together. Mix until it gets light and fluffy, about 3-4 minutes.
Incorporating Eggs and Vanilla
Next, add 2 large eggs to the butter mix. Do this one at a time, mixing well after each egg. Then, add 2 teaspoons of pure vanilla extract. Stir until it is fully blended.
Combining Dry and Wet Ingredients
Gradually add your dry flour mix to the wet mixture. Mix on low speed until everything is just combined. Be careful not to overmix, as this can make the bars tough.
Folding in Sprinkles and Chocolate Chips
Now, take a spatula and gently fold in ½ cup of rainbow sprinkles and 1 cup of white chocolate chips. Make sure they are evenly spread throughout the dough.
Spreading and Decorating the Cookie Dough
Transfer the cookie dough into your prepared baking pan. Use the back of a spoon or an offset spatula to spread it out evenly. For a fun touch, sprinkle more rainbow sprinkles on top.
Baking Time and Temperature
Place the pan in your preheated oven. Bake for 20-25 minutes. The edges should turn golden, and a toothpick should come out clean or with a few crumbs.
Cooling and Serving Suggestions
Once done, take the pan out of the oven and let it cool completely on a wire rack. When cool, lift the bars out using the parchment paper. Cut them into squares for serving. Enjoy your funfetti sugar cookie bars on a colorful platter!
Tips & Tricks
Baking Tips for Perfect Cookie Bars
For perfect funfetti sugar cookie bars, keep a few tips in mind:
– Use Room Temperature Ingredients: Make sure your butter and eggs are at room temperature. This helps create a smooth batter.
– Measure Flour Correctly: Spoon the flour into your measuring cup, then level it off. This prevents dense bars.
– Avoid Overmixing: Mix just until the ingredients combine. Overmixing can lead to tough bars.
Common Mistakes to Avoid
Many bakers make simple mistakes. Here are some to watch for:
– Not Preheating the Oven: Always preheat your oven to 350°F. This ensures even baking.
– Skipping the Parchment Paper: Use parchment paper to help remove the bars easily.
– Baking Too Long: Check the bars a few minutes early. They should be golden around the edges.
How to Ensure Chewy Texture
For a chewy texture, follow these steps:
– Use Brown Sugar: The brown sugar adds moisture and chewiness.
– Chill the Dough: If you have time, chill the dough for 30 minutes. This helps the bars stay thick.
– Do Not Overbake: Remove the bars when they are slightly underbaked. They will continue to cook in the pan.
Pro Tips
- Use Room Temperature Ingredients: Ensure your butter and eggs are at room temperature for a smoother batter and better texture in your cookie bars.
- Don’t Overmix the Dough: Mix just until the dry ingredients are incorporated to avoid tough cookie bars. A few lumps are okay!
- Chill the Dough (Optional): For thicker cookie bars, consider chilling the dough for 30 minutes before baking. This helps them hold their shape better.
- Check for Doneness: Since ovens vary, start checking for doneness a few minutes before the minimum baking time to avoid overbaking.
Variations
Flavor Variations
You can switch up the flavors in these bars. Try using dark chocolate chips instead of white. It adds a rich taste that many love. You can also mix in butterscotch chips for a sweet twist. For a fruity flavor, add chopped dried cherries or cranberries. Remember, the key is to balance the sweetness with these flavors.
Frosting Options for the Cookie Bars
Frosting can make these bars even better! A simple vanilla buttercream pairs well. Just mix butter, powdered sugar, and vanilla until smooth. If you want a splash of color, use food coloring. Cream cheese frosting works great, too. It adds a tangy flavor that kids adore. Try drizzling melted chocolate on top for an extra treat.
Seasonal Add-ins
Make your funfetti bars fit any season with fun add-ins. For spring, use pastel-colored sprinkles. In summer, try adding mini marshmallows for a s’mores feel. Fall brings pumpkin spice chips, which add warmth to each bite. For winter holidays, use red and green sprinkles for a festive touch. These simple swaps make the bars special for any occasion.
