- 2 ½ cups all-purpose flour - 1 teaspoon baking soda - ½ teaspoon salt The dry ingredients form the base of our cookie bars. I use all-purpose flour for a soft and chewy texture. Baking soda gives the bars a light lift, while salt adds balance to the sweetness. - 1 cup (2 sticks) unsalted butter, softened - 1 cup granulated sugar - ½ cup brown sugar, packed - 2 large eggs - 2 teaspoons vanilla extract For the wet ingredients, I start with softened unsalted butter. It mixes well and creates a rich flavor. The granulated and brown sugars blend together, adding sweetness and depth. Eggs help bind the mixture, while vanilla extract gives a warm aroma. - ½ cup rainbow sprinkles (plus extra for topping) - 1 cup white chocolate chips - Optional: Frosting ingredients Sprinkles are key to the fun in Funfetti bars! I fold in half a cup into the dough for color and crunch. White chocolate chips add a creamy sweetness. If you want frosting, I suggest using a mix of butter, powdered sugar, cream, and vanilla for a smooth finish. These ingredients come together to create a treat that is fun, colorful, and oh-so-delicious! First, preheat your oven to 350°F (175°C). This step is key to baking your bars evenly. Next, grab a 9x13-inch baking dish. Line it with parchment paper, leaving some paper hanging over the edges. This helps you lift the bars out easily when they’re done. In a medium bowl, whisk together the dry ingredients. You need 2 ½ cups of flour, 1 teaspoon of baking soda, and ½ teaspoon of salt. This mixture is the base of your cookie dough. In a large mixing bowl, beat the soft butter, granulated sugar, and brown sugar until creamy. This takes about 2-3 minutes. Next, add 2 large eggs one at a time, mixing well after each. Stir in 2 teaspoons of vanilla extract for a sweet flavor. Now, gradually add the dry mix to the wet mix. Stir until just combined. It’s important not to overmix, or your bars may turn tough. Fold in ½ cup of rainbow sprinkles and 1 cup of white chocolate chips. Use a spatula to make sure they spread evenly. Then, pour the dough into the prepared dish. Spread it out evenly. Bake the bars in the preheated oven for 22-25 minutes. They are done when the edges are golden and the center looks set. A toothpick should come out with a few moist crumbs, but not wet batter. Once baked, let them cool before frosting, if you choose to add it. To get the best texture for your Funfetti Sugar Cookie Bars, avoid overmixing the dough. When you combine the wet and dry ingredients, mix just until they come together. Overmixing can make the bars tough. After baking, check for doneness with a toothpick. Insert the toothpick in the center of the bars. If it comes out mostly clean with a few moist crumbs, they are ready. For a smooth and fluffy frosting, keep your butter at room temperature. Soft butter blends well with powdered sugar. If your frosting is too thick, adjust the consistency with heavy cream or milk. Just add a little at a time until it is perfect for spreading. To cut the bars for uniform pieces, use a sharp knife. Clean the knife between cuts to keep edges neat. You can serve them plain for a simple treat. For a fun twist, add frosting and extra sprinkles on top. This makes each bite even more joyful and festive! {{image_2}} You can make funfetti sugar cookie bars even more fun! Try different sprinkles, like chocolate or pastel colors. Want to add more texture? You can mix in nuts like walnuts or pecans. Dried fruits, such as cranberries or raisins, also work well. These changes will give your bars a unique twist. Do you need a vegan option? Substitute butter with coconut oil or a plant-based butter. For eggs, use mashed banana or applesauce as an egg replacer. If you’re gluten-free, swap out regular flour with almond or coconut flour. These swaps will keep your bars tasty and safe for everyone. Make your funfetti bars fit any season! Use themed sprinkles for holidays like Christmas or Halloween. You can even change flavors to match the time of year. Think pumpkin spice in fall or peppermint in winter. These small changes can make your cookie bars festive and fun for any occasion! To keep your Funfetti sugar cookie bars fresh for 3-5 days, store them in a cool, dry place. Place the bars in a single layer on a plate or in a small container. If you stack them, use parchment paper between layers to prevent sticking. This simple step helps maintain their soft texture and yummy flavor. Freezing these bars is easy and smart if you want to enjoy them later. Once the bars cool completely, cut them into squares. Wrap each square tightly in plastic wrap or foil. Place the wrapped bars in a freezer-safe bag or container. This way, they can stay fresh for up to three months. When you want to eat one, just let it sit at room temperature for about an hour, or warm it in the microwave for a few seconds. For optimal freshness, use airtight containers to store your Funfetti bars. Glass or plastic containers with a secure lid work best. These containers keep air out and moisture in. This method helps preserve the bars’ delicious taste and soft texture. Plus, it makes grabbing a treat quick and easy! Yes, you can use different types of chocolate chips. Milk chocolate chips add sweetness. Dark chocolate chips bring a rich flavor. You can mix and match to suit your taste. Just keep the amount the same, about one cup. To store leftover bars, place them in an airtight container. Keep the container at room temperature for 3-5 days. If you want them to last longer, freeze them. Wrap each bar in plastic wrap, then put them in a freezer bag. This helps prevent freezer burn. If you want a vegan option, use flaxseed meal or applesauce. For flaxseed, mix one tablespoon with three tablespoons of water. Let it sit until it thickens. This replaces one egg. Use a quarter cup of applesauce for one egg too. Both options work well in the recipe. Yes, you can serve these bars without frosting. They taste great on their own. Just cut them into squares after they cool.

Ingredients
  

2 ½ cups all-purpose flour

1 teaspoon baking soda

½ teaspoon salt

1 cup (2 sticks) unsalted butter, softened

1 cup granulated sugar

½ cup brown sugar, packed

2 large eggs

2 teaspoons vanilla extract

½ cup rainbow sprinkles (plus extra for topping)

1 cup white chocolate chips

Frosting (optional):

1 cup unsalted butter, softened

4 cups powdered sugar

2 tablespoons heavy cream (or milk)

1 teaspoon vanilla extract

Instructions
 

Preheat your oven to 350°F (175°C) and line a 9x13-inch baking dish with parchment paper, leaving some overhang for easy removal later.

    In a medium bowl, whisk together the flour, baking soda, and salt. Set aside.

      In a large mixing bowl, beat the softened butter, granulated sugar, and brown sugar together until creamy and fluffy, about 2-3 minutes.

        Add in the eggs one at a time, mixing well after each addition. Then, stir in the vanilla extract.

          Gradually add the flour mixture to the wet ingredients, mixing until just combined. Be careful not to overmix.

            Fold in the rainbow sprinkles and white chocolate chips with a spatula until evenly distributed.

              Pour the cookie dough into the prepared baking dish and spread it evenly with the spatula.

                Bake in the preheated oven for 22-25 minutes, or until the edges are golden and the center is set. A toothpick should come out mostly clean with a few moist crumbs.

                  While the bars are cooling, prepare the frosting (if using): In a large bowl, beat the softened butter until creamy, about 2 minutes. Gradually add powdered sugar, heavy cream, and vanilla extract and beat until fluffy and well combined.

                    Once the cookie bars have cooled completely, spread the frosting evenly on top and sprinkle extra rainbow sprinkles on top for decoration.

                      Use the parchment paper overhang to lift the bars out of the baking dish. Cut into squares and serve.
