Ingredients You’ll Need

¾ cup (170g) unsalted butter, softened: Adds a rich flavor and tender texture. Make sure it’s at room temperature for easy creaming.
¾ cup (150g) granulated sugar: This sweetener is essential for that sweetness and flakiness. You can use coconut sugar for a healthier alternative.
1 egg: The egg binds everything together, providing moisture and richness. Room temperature eggs work best for this recipe.
1 teaspoon vanilla extract: Pure vanilla extract lends a delightful and familiar flavor.
½ teaspoon almond extract (optional): Adds a unique twist; feel free to skip it if you’re not a fan.
½ teaspoon baking soda: This leavening agent helps the bars rise while keeping them soft and chewy.
½ teaspoon cream of tartar: Works with baking soda to stabilize the dough and enhance the texture.
½ teaspoon salt: Just a pinch enhances all the flavors.
2 cups (248g) all-purpose flour: The foundation of your cookie bars. For gluten-free options, substitute with a 1:1 gluten-free flour blend.
½ cup (113g) unsalted butter (for frosting), softened: Ensures your frosting is creamy and smooth.
¼ teaspoon salt (for frosting): Balances the sweetness of the powdered sugar.
3 cups (339g) powdered sugar: Provides sweetness and structure to the frosting. Sift it to avoid clumps.
1 teaspoon vanilla extract (for frosting): Enhances the flavor of your frosting, making it more delightful.
1-3 tablespoons (5-15ml) milk or heavy whipping cream: Adjusts consistency for a smooth frosting texture. Use as needed.
Sprinkles and/or food coloring (if desired): Brightens up your bars and makes them fun and festive!

How to Make Sugar Cookie Bars

Preheat and Prepare: Set your oven to 350°F (175°C). Line a 9×13-inch pan with foil and spray it generously with nonstick cooking spray to ensure easy removal.
Cream Butter and Sugar: In the bowl of a stand mixer fitted with the paddle attachment, cream together ¾ cup (170g) softened unsalted butter and ¾ cup (150g) granulated sugar until light and fluffy. This should take about 2 minutes.
Add Egg and Extracts: Beat in 1 egg, along with 1 teaspoon vanilla extract and ½ teaspoon almond extract (if using). Mix well until fully combined.
Mix in Dry Ingredients: Add ½ teaspoon baking soda, ½ teaspoon cream of tartar, and ½ teaspoon salt to the mixture. Gradually mix in 2 cups (248g) all-purpose flour until just incorporated. Avoid overmixing to keep the bars tender.
Spread the Dough: Transfer the dough to your prepared pan and press it evenly into the corners. It should be smooth and level.
Bake: Slide the pan into the preheated oven and bake for 14-19 minutes, or until the edges are just golden and the center looks slightly underdone.
Cool Completely: Once baked, allow the bars to cool completely in the pan before frosting.

Make the Frosting

Beat the Butter: In a mixing bowl, beat ½ cup (113g) softened unsalted butter with a hand or stand mixer until creamy.
Add Salt and Sugar: Mix in ¼ teaspoon salt, then gradually add in 3 cups (339g) powdered sugar until the mixture is crumbly.
Combine with Vanilla and Cream: Pour in 1 teaspoon vanilla extract and 1 tablespoon milk or heavy cream. Beat until the frosting is smooth and creamy. Adjust the consistency with more milk if necessary.
Add Color: If you want to tint your frosting, now’s the time! Stir in food coloring until you achieve your desired hue.
Frost the Bars: Once the bars are completely cool, spread the frosting evenly over the top. Top with sprinkles if desired.

Storing & Reheating

Store your sugar cookie bars in an airtight container at room temperature for up to 3 days for the best flavor and texture. If you need them to last longer, refrigerate the bars in the same container for up to a week. For longer storage, you can freeze the bars—just wrap them tightly in plastic wrap and then place them in a freezer-safe container. They can be frozen for up to 3 months. When ready to enjoy, simply thaw them at room temperature for a few hours. Keep in mind that the frosting might lose some of its freshness, so a quick whip can revive it!

Chef’s Helpful Tips

Be sure the butter is softened adequately; cold butter will not cream well with sugar, leading to dense bars.
Watch the baking time closely. The edges should turn golden, while the center appears slightly underbaked—this helps create that perfect chewy texture.
Allow the bars to cool completely before frosting; otherwise, the heat will melt the frosting.
Don’t skip the cream of tartar; it helps maintain softness and adds a slight chewiness.
Feel free to experiment with flavorings in the frosting—switch out vanilla extract for lemon or almond for a unique twist.

These sugar cookie bars are a wonderfully simple dessert that’s bound to please. Their soft, chewy texture paired with creamy frosting makes them a joy to eat. These bars are not just about flavor; they’re also about bringing a little sweetness to life’s everyday moments.

Recipe FAQs

Can I make these sugar cookie bars gluten-free?

Absolutely! Simply substitute the all-purpose flour with a gluten-free flour blend that is a 1:1 ratio. You might also want to add a teaspoon of xanthan gum for better texture if your blend doesn’t include it.

How can I store leftover bars?

To keep your sugar cookie bars fresh, store them in an airtight container at room temperature for up to 3 days. For longer storage, you can refrigerate them for up to a week or freeze them for up to 3 months.

What can I use instead of almond extract?

If you prefer not to use almond extract, you can simply omit it or replace it with an additional teaspoon of vanilla extract for a pure vanilla flavor.

Can I use dairy-free butter for the frosting?

Yes, using a dairy-free butter alternative works beautifully in the frosting and for the bars themselves, making this a great option for those with dairy allergies. Just ensure the alternative behaves similarly in baking.
