Ingredients for 4th of July Cookie Bars
For the cookie bars:
- 1/2 cup unsalted butter, softened
- 3/4 cup granulated sugar
- 1 egg
- 1 1/2 teaspoons vanilla extract
- 1 3/4 cups all-purpose flour
- 1/2 teaspoon baking powder
- 1/4 teaspoon salt
- 2 to 4 tablespoons 4th of July sprinkles
For the frosting:
- 1/2 cup unsalted butter, softened
- 2 cups powdered sugar
- 1 to 2 tablespoons milk
- 1/2 teaspoon vanilla extract
- Extra 4th of July sprinkles for topping
How to Make 4th of July Cookie Bars
1. Preheat your oven to 350°F. Line an 8×8-inch baking pan with parchment paper.
2. In a large mixing bowl, cream the softened butter and granulated sugar together until the mixture looks light and smooth. Add the egg and vanilla extract, then mix again until everything is combined.
3. Add the flour, baking powder, and salt. Mix just until a soft dough forms. Try not to overmix here, since that can make the bars less soft. Gently fold in the sprinkles.
4. Press the dough evenly into your prepared pan. The dough will be thick, so I like to use clean hands or the back of a spoon to help smooth it out into the corners.
5. Bake for 18 to 22 minutes, or until the center looks set and the edges are just lightly golden. You do not want to overbake these if you want that soft sugar cookie bar texture.
6. Let the bars cool completely in the pan before frosting.
7. To make the frosting, beat the softened butter until smooth. Add the powdered sugar, vanilla extract, and 1 tablespoon of milk. Beat until creamy. If needed, add a little more milk until the frosting is spreadable.
8. Spread the frosting over the cooled bars, then top with extra patriotic sprinkles. Slice into squares and serve.
Pro Tips for 4th of July Frosted Sugar Cookie Bars
- Use jimmies-style sprinkles if you can. They usually hold their color better in the dough and won’t bleed as much as nonpareils or sanding sugar.
- Do not overbake the bars. The edges should be lightly golden, but the center should still look soft and set. That’s what gives these frosted sugar cookie bars their soft texture.
- Make sure the bars are completely cool before frosting them. If they’re still warm, the frosting will melt and slide around instead of staying fluffy on top.
- If your dough feels sticky, lightly flour your hands before pressing it into the pan. That makes it much easier to spread evenly.
- For a little extra bakery-style flavor, you can add a tiny splash of almond extract to the dough or frosting. I would keep it light so it doesn’t overpower the vanilla (like maybe ¼-½ teaspoon for the cookie dough and definitely only a ¼ teaspoon for the frosting).
- These bars are easy to decorate for all kinds of summer gatherings, so you can swap the sprinkle colors if you want to use the same recipe for another occasion later.
FAQs
What do these 4th of July cookie bars taste like?
They taste like soft sugar cookies in bar form, topped with a sweet vanilla frosting. If you like classic sugar cookies, you’ll probably love these.
Can I make these frosted sugar cookie bars ahead of time?
Yes. You can bake the bars a day ahead, then frost and decorate them once they’ve cooled. They also keep well for a couple of days, which makes them great for parties and holiday prep.
How should I store these bars?
Store them in an airtight container at room temperature for about 2 days, or in the refrigerator for a little longer. I actually like them kind of chilled, because if I’m taking them to some kind of event or party, I feel like they stand a better chance in the heat that way. Plus, there’s just something about the flavor of a chilled sugar cookie that I love. However, you can serve at room temperature as long as your environment isn’t so hot and humid the frosting melts.
Can I use store-bought frosting?
Yes, if you want to save time, store-bought vanilla frosting will work. I do think homemade frosting tastes better here, but either option is fine if you’re keeping things simple.
Can I double this recipe?
Yes. This version is made for an 8×8 pan, but you can double it for a 9×13 pan if you want to make more Fourth of July treats for a crowd.
What kind of sprinkles work best?
Red, white, and blue jimmies are my favorite for this recipe. I found some sprinkles that had jimmies and disc type sprinkles, but the discs were star-shaped. They look festive and tend to bake up nicely in the dough and on top of the frosting.
These 4th of July cookie bars are one of my favorite easy 4th of July desserts because they’re simple, cute, and so easy to share. The soft sugar cookie base and creamy frosting make them feel classic, while the patriotic sprinkles make them perfect for summer celebrations. If you need Fourth of July treats that are easy to make but still look fun on a dessert table, these frosted sugar cookie bars are such a good choice.
