The BEST Sugar Cookie Bars

If you love soft sugar cookies, you’re going to be obsessed with these easy Sugar Cookie Bars. Inspired by The Best Sugar Cookies you’ll find around Southern Utah (yes, similar to those iconic Swig sugar cookies), this recipe transforms a classic favorite into a thick, frosted dessert bar that’s easy to make at home. I find myself reaching for this recipe all year long, whether it’s for Valentine’s Day, birthdays, summer gatherings, or potlucks.

SUGAR COOKIE BARS

Not only are these delicious, but they are easier to make than the classic sugar cookie. There’s no rolling pin, no cookie cutters, no chilling required, and you don’t have to scoop individual portions of dough. Instead, the dough is spread throughout a baking pan. After they’re done baking and cooled, they are topped with a generous amount of homemade frosting and colorful sprinkles! It’s one of the fastest and best sugar cookie bar recipes for beginners and busy bakers. The hint of birthday cake extract (or vanilla) gives it that nostalgic flavor everyone knows and loves. These cookie bars will always remain in my top 5 favorite desserts. They are so soft, chewy, and festive!

The BEST Sugar Cookie Bars

Ingredients

Sugar Cookie Bars

  • 3 cups all-purpose flour
  • 1 teaspoon baking powder
  • 1 teaspoon baking soda
  • 1/2 teaspoon salt
  • 3/4 cup butter, softened
  • 1 1/2 cups granulated sugar
  • 3 large eggs
  • 1 heaping Tablespoon sour cream
  • 1 teaspoon vanilla or birthday cake extract (I prefer this Birthday Cake Extract)

Frosting

  • 3/4 cup butter, softened
  • 4 cups powdered sugar
  • 1/4 cup milk
  • 1 teaspoon vanilla or birthday cake extract
  • 1/4 teaspoon salt
  • Food coloring (optional)
  • Sprinkles

Instructions

For The Sugar Cookie Bars

Preheat oven to 350 degrees F. Line a 9×13-inch baking pan with parchment paper. Set aside.

Combine flour, baking powder, baking soda and salt in a medium bowl. Set aside.

In a large bowl or stand mixer, cream together the butter and sugar until light and fluffy, about 2 minutes. Add the eggs and combine well. Add the sour cream and vanilla; mix until combined. Slowly add the flour mixture just until combined.

Press the mixture evenly into the bottom of the prepared pan. You can spray a little cooking spray on your hands, so the batter doesn’t stick to them. Bake for 17 to 20 minutes only! Or just until edges become slightly golden. Remove from the oven and let cool completely before frosting.

For The Frosting

In a medium bowl, beat together the butter, 2 cups of powdered sugar, and milk until combined. Slowly add in the remaining two cups of powdered sugar until combined. Then add the vanilla and salt.

Optional: Drop several drops of the desired color of food dye into the frosting and beat until creamy and the desired color.

Frost with frosting and sprinkle with lots of sprinkles. Cut into bars and serve!

Servings

Yields: 16 sugar cookie bars. You can cut each bar in half, creating 32 smaller bars if serving a large crowd.

Storage

Store your frosted sugar cookie bars in an airtight container at room temperature for up to 2-3 days, placing parchment paper between layers if stacking to prevent sticking. For longer freshness, refrigerate them for up to 5 days and let them sit at room temperature for 20-30 minutes before serving so the frosting softens. You can also freeze the bars (frosted or unfrosted) by wrapping them tightly and storing in a freezer-safe container for up to 2 months; thaw overnight in the refrigerator or at room temperature before enjoying.

Holly’s Tips for The Best Sugar Cookie Bars with Frosting:

  • Soften The Butter First: Your butter should be soft to the touch but not melted. This helps create a smooth, creamy dough and ensures the bars bake up light and tender; not greasy or dense.
  • Avoid Overmixing: Once you add the dry ingredients, mix just until combined. Overmixing can lead to tough, dense bars instead of soft and chewy ones.
  • Press Dough Evenly Into Pan: Take a minute to spread the dough into an even layer. Lightly greasing your hands or using parchment paper helps prevent sticking and gives you a smooth surface for even baking.
  • Keep An Eye On Baking Time: The key is to not overbake! Bake just until the edges are set and the center looks slightly underdone. Overbaking will make the bars dry instead of soft and chewy.
  • Allow Bars To Cool Completely Before Frosting: Let the bars cool fully before adding frosting. If they’re even slightly warm, the frosting will melt and lose that thick, fluffy texture.
  • Before Serving: For neat, bakery-style squares, use a sharp knife and wipe it clean between cuts. You can even chill the bars briefly before slicing for extra clean edges.

Frequently Asked Questions:

Can I make Sugar Cookie Bars ahead of time?

Yes! These bars are perfect for making ahead. You can bake and frost them 1–2 days in advance. Just store them in an airtight container at room temperature or in the refrigerator for longer freshness.

Do Sugar Cookie Bars need to be refrigerated?

They don’t have to be, but you can refrigerate them if you prefer. At room temperature, they’ll stay fresh for about 2-3 days. In the fridge, they’ll last up to 5 days. Just let them come to room temperature before serving for the best texture.

Why are my Sugar Cookie Bars dry?

Dry bars are usually the result of overbaking or adding too much flour. Be sure to measure your flour correctly and remove the bars from the oven when the center is just set.

Can I use unsalted butter instead of salted butter?

Yes, you can substitute unsalted butter. Just add an extra pinch of salt to both the bars and the frosting to balance the sweetness.

How can I make Sugar Cookie Bars vegan?

To make Sugar Cookie Bars vegan, you’ll need a few simple swaps while keeping the same easy method. Replace the butter in both the bars and frosting with a plant-based vegan butter (stick-style works best for structure). Swap the eggs for a vegan egg substitute, such as flax eggs, and use a dairy-free sour cream or plain vegan yogurt. For the frosting, use plant-based butter and your choice of dairy-free milk (like almond, oat, or soy). Make sure your sugar and sprinkles are certified vegan. Mix, bake, and frost as directed.

How can I make Sugar Cookie Bars gluten-free?

To make Sugar Cookie Bars gluten-free, simply substitute the all-purpose flour with a 1:1 gluten-free baking flour blend that contains xanthan gum for the best texture. Keep all other ingredients the same, including the butter, sugar, eggs, sour cream, and extracts. Mix the dough just until combined, press it into the pan as directed, and bake as usual, just keep an eye on them since gluten-free flours can sometimes bake a little faster or slightly differently. Let them cool completely before frosting for the best results.
