ingredients in sugar cookie bars

Flour: Use all-purpose flour and be sure to measure it correctly.

Baking Powder: This keeps the bars nice and soft like sugar cookies should be.

Unsalted Butter: Be sure to soften your butter before making the cookies. If you need to substitute salted butter, omit the salt in the recipe.

Eggs: Needed for structure in cookie bars.

Sugar: Sugar cookies typically use granulated sugar. You’ll also need powdered sugar for the frosting.

Vanilla: Used for flavor in both the frosting and cookie bars.

Sprinkles: You can use nonpareils or jimmies. I prefer jimmies, but either one works. Find red and blue sprinkles on amazon!

Milk: This is for the frosting. You can use regular milk or heavy cream.

Substitutions and Tips

  • Flavoring: Add 1 teaspoon almond or lemon extract to the bars for extra flavor.
  • Use ANY color sprinkles for any occasion.
  • Jimmie sprinkles are best for baking as they tend not to dissolve.
  • Want semi-homemade? Use a can of frosting to save time.
  • Color your frosting red and blue or make a flag decoration on top.

How do you know sugar cookie bars are done baking?

These need the toothpick test. I also look to see if they have just lost their glossy sheen.

How to store cookie bars?

Store these in an airtight container on the counter for up to 2 days or in the refrigerator for up to 4 days.

Can you freeze fireworks sugar cookie bars?

Yes you can! Freeze them with or without frosting.

  • 4 ¼ cup (558g) all-purpose flour
  • 1 teaspoon baking powder
  • ¼ teaspoon salt
  • 1 cup (226g) unsalted butter , softened
  • 1 ⅔ cup (334g) granulated sugar
  • 3 large eggs
  • 1 teaspoon vanilla extract
  • ½ cup patriotic sprinkles


  • ½ cup (113g) unsalted butter , softened
  • 2 ½ cups (283g) powdered sugar
  • Pinch salt
  • 1 teaspoon vanilla extract
  • 1 ½ tablespoons whole milk
  • Patriotic sprinkles for garnish
  • Preheat the oven to 375°F. Line a 9×13 baking dish with parchment paper or foil and spray with cooking spray, set it aside. In a large bowl whisk together the flour, baking powder, and salt, set aside.

  • In the body of a stand mixer with the paddle attachment cream the butter with the sugar until light and fluffy, 2 minutes. Scrape down the sides. Add the eggs one at a time, letting the first egg mix all the way in before adding the next. Add the vanilla and mix it in until combined. Add the flour mixture and stir it in until combined, scrape down the sides, and mix it in a few more times until fully mixed in. Add the sprinkles and stir them in.

  • Press the cookie dough into the prepared baking dish until even. Bake for 25-28 minutes until lightly golden and a toothpick inserted into the center comes out clean. Place on a wire rack to cool completely.

  • While the bars cool, make the frosting by placing the butter into a large bowl with an electric hand mixture and whipping until smooth. Add in the powdered sugar a little at a time until fully mixed. Add the salt, vanilla, and 1 tablespoon milk, mix it in until combined then place the mixer on medium-high speed and whip for 3 minutes until light and fluffy, adding more milk as needed for consistency.

  • Once the cookie is cool, take it out of the baking dish and frost the top. Add more sprinkles if desired. Cut into bars and serve.

  • Store in an airtight container in the refrigerator for up to 3 days or freeze for up to 2 months.

  • These sugar cookie bars are thicker than your normal sugar cookie bar. They cook up nice and thick with a terrific chew. They taste just like frosted sugar cookies but in bar form.
  • Add your favorite extract flavors to mix up the flavor of the bars. You can also dye the frosting whatever color you like.
  • I use jimmie style sprinkles because they tend not to bleed.
