- 2 ¾ cups all-purpose flour - 1 teaspoon baking powder - ½ teaspoon baking soda - ½ teaspoon salt - 1 cup unsalted butter, softened - 1 cup granulated sugar - ½ cup brown sugar, packed - 2 large eggs - 2 teaspoons vanilla extract - ½ cup rainbow sprinkles (plus more for topping) - 1 cup white chocolate chips (optional) When I make Funfetti Sugar Cookie Bars, I start with fresh, high-quality ingredients. The flour forms the base, giving the bars their structure. Baking powder and baking soda help them rise and stay soft. Salt balances the sweetness and enhances flavor. Using unsalted butter is key. It should be soft but not melted, so it creams well with the sugars. Granulated and brown sugars add sweetness and moisture. Brown sugar brings a slight caramel flavor. Eggs provide moisture and help bind everything. Vanilla extract adds a warm, inviting aroma. Rainbow sprinkles give the bars a fun, festive look and a bit of crunch. You can add white chocolate chips for extra sweetness, but it's optional. Feel free to get creative! Different types of sprinkles or chocolate can change the flavor and look. {{ingredient_image_1}} 1. Preheat oven and prepare baking pan Set your oven to 350°F (175°C). Grab a 9x13 inch baking pan. Line it with parchment paper. Leave some paper hanging over the sides for easy lifting later. 2. Mix dry ingredients In a medium bowl, whisk together 2 ¾ cups of all-purpose flour, 1 teaspoon of baking powder, ½ teaspoon of baking soda, and ½ teaspoon of salt. This mix is key for the bars' texture. 3. Cream butter and sugars In a large bowl, use an electric mixer to beat 1 cup of softened butter with 1 cup of granulated sugar and ½ cup of packed brown sugar. Mix until light and fluffy, about 2-3 minutes. 4. Add eggs and vanilla Beat in 2 large eggs, one at a time. Then add 2 teaspoons of vanilla extract. Mix well after each addition to build flavor. 5. Mix dry and wet ingredients Gradually add the dry mixture to the wet ingredients. Mix until just combined. Avoid overmixing, as this can make the bars tough. 6. Fold in sprinkles and chocolate chips Gently fold in ½ cup of rainbow sprinkles and 1 cup of white chocolate chips if you want them. This adds fun and sweetness to your bars. 7. Spread dough in pan Spread the dough evenly into your prepared pan. Make sure to smooth the top with a spatula. 8. Bake time and doneness check Bake for 20-25 minutes. The edges should be golden. Insert a toothpick in the center; it should come out clean. 9. Cooling and slicing instructions Let the bars cool in the pan for 10-15 minutes. Lift them out using the parchment paper. Cool completely on a wire rack. Once cool, slice them into bars. Enjoy! - Avoid overmixing the batter: Mix just until combined for soft bars. If you mix too much, the bars can turn tough. This step helps keep them light and chewy. - Ensure proper baking temperature: Always preheat your oven to 350°F (175°C). An oven that is too hot can burn the edges. Use an oven thermometer for accuracy if you have one. - Arranging bars on a platter: Once your bars cool, cut them into squares. Place them on a bright platter. This adds color and makes them fun to serve. - Adding extra sprinkles or toppings: Top your bars with more rainbow sprinkles. You can also drizzle melted chocolate on top for a special touch. This makes them look even more festive and inviting! Pro Tips Use Room Temperature Ingredients: Make sure your butter and eggs are at room temperature for better mixing and a smoother dough. Don’t Overmix: Mix the dry ingredients into the wet just until combined to keep your bars from becoming tough. Check for Doneness: Keep an eye on the edges; they should be golden brown and a toothpick should come out clean from the center. Cool Completely: Allow the bars to cool completely on a wire rack before slicing to ensure clean cuts and prevent them from crumbling. {{image_2}} You can switch up the sprinkles you use. Try using chocolate sprinkles for a rich taste. You could also use pastel or seasonal sprinkles for special occasions. This adds a fun twist to your dessert. Substituting chocolate chips is another great option. You can use milk chocolate, dark chocolate, or even peanut butter chips. Each choice brings a new layer of flavor to your cookie bars. Don't be afraid to mix and match to find your favorite combo! If you need a gluten-free option, you can use gluten-free flour. Look for a blend that works well in baking. This allows everyone to enjoy these treats without worry. For a vegan version, replace the butter with a plant-based alternative. Use flax eggs or applesauce instead of regular eggs. These swaps keep the dessert delicious while meeting dietary needs. Enjoy the same great taste in a friendly way! To keep your Funfetti Sugar Cookie Bars fresh, follow these tips: - Short-term storage: Place the bars in an airtight container. They stay tasty for up to a week at room temperature. If you want them to last longer, keep them in the fridge. This can add a nice chill to the bars. - Long-term freezing instructions: For longer storage, slice the bars and wrap each piece tightly in plastic wrap. Then, put them in a freezer-safe bag. They can stay in the freezer for up to three months. When you're ready to enjoy, just thaw them at room temperature. When you want to serve your Funfetti Sugar Cookie Bars warm, here are easy steps: - Warm-up tips for serving: Preheat your oven to 300°F (150°C). Place the bars on a baking sheet. Heat for about 5-10 minutes until warm. You can also microwave a single bar for about 15-20 seconds. Enjoy them warm for a soft, gooey treat! How do I make Funfetti Sugar Cookie Bars from scratch?

For a fruity twist, consider using dried fruit or chopped nuts. All these options will add delicious flavor to your cookie bars. Why are my cookie bars too dry?
