Loved by kids and adults alike, these Frosted Sugar Cookie Bars offer a delightful balance of flavors and textures. The cookie base is wonderfully soft and chewy, with a subtle vanilla essence that isn’t overly sweet, creating the perfect canvas for the creamy frosting.

Beyond flavor, simply changing the frosting color and adding a variety of fun sprinkles or edible decorations can completely transform these bars for Valentine’s Day, a patriotic 4th of July barbecue, adorable baby showers, or any theme you desire.

The Convenience Factor: Why These Easy Dessert Bars Are a Must-Try

As someone who loves to host, I am always on the lookout for easy dessert recipes that can be prepared in advance, and these Frosted Sugar Cookie Bars fit the bill perfectly.

Simply wrap it tightly in plastic wrap and store it in your refrigerator until you’re ready to bake. This make-ahead capability is a lifesaver when planning for busy events!

This is hands down one of my absolute favorite sugar cookie recipes, and I’ve successfully made these easy sugar cookie bars for countless occasions: Halloween parties, engagement celebrations, school bake sales, classroom parties, and even a large family reunion. Their incredible versatility ensures they’re a hit during any holiday season or special event, consistently delivering delicious results that everyone raves about.

Essential Ingredients for the Best Sugar Cookie Bars Recipe

To achieve these perfectly delicious frosted treats, you’ll need a few key ingredients for both the cookie base and the luscious frosting. For a complete list of ingredients with precise measurements and detailed instructions, please scroll down to the bottom of this post for the full printable recipe card.

For the Sugar Cookie Bars:

  • Butter: Unsalted butter is highly recommended. Using unsalted butter gives you complete control over the total salt content in your recipe, allowing for a more balanced flavor profile.

  • Sugar: Stick with classic white granulated sugar for that quintessential sugar cookie sweetness and tender crumb.

  • Eggs: Essential for binding the ingredients and adding richness and moisture to the cookie dough, contributing to its chewy texture.

  • Vanilla extract: Pure vanilla extract is crucial for a deep, authentic vanilla flavor. A good quality extract makes a noticeable difference.

  • Flour: All-purpose flour is the backbone of this recipe, providing the necessary structure for the cookie bars.

  • Salt: A pinch of salt balances the sweetness and enhances all the other flavors in the cookie.

  • Baking powder: This leavening agent helps the cookie bars rise slightly, giving them a softer, more cake-like texture compared to flatter, crispier cookies.

For the Rich and Fluffy Frosting:

  • Butter: Again, unsalted butter is preferred for consistency in flavor. Ensure it’s softened for optimal creaming.
  • Shortening: This is a key ingredient for achieving a super stable and thick frosting. Unlike butter, shortening is 100% fat and doesn’t melt as readily, which helps the frosting hold its shape beautifully, especially in warmer conditions. Using both butter and shortening gives you the best of both worlds: the delicious buttery flavor with enhanced stability.

  • Almond or Vanilla extract: Or, for the most exquisite flavor, a delightful combination of both! The almond extract provides a lovely, subtle nutty undertone that pairs wonderfully with the vanilla.

  • Powdered sugar:Also known as confectioners’ sugar, this fine sugar is crucial for a smooth, lump-free frosting texture.

  • Milk: Any choice of dairy milk or plant-based milk will work as a thinning agent for the frosting, allowing you to achieve your desired consistency.

Ingredients for the frosting, including butter, shortening, powdered sugar, and milk.

  • Food coloring and sprinkles: These are entirely optional but highly encouraged! They add a vibrant, festive touch that makes these cookie bars truly pretty and perfect for any theme.

Simplified Steps: How to Make Frosted Sugar Cookie Bars

Making these delightful Frosted Sugar Cookie Bars is a straightforward process. Follow these simple steps to create a batch of perfect homemade treats:

STEP ONE: Prepare Your Baking Pan and Preheat the Oven. Begin by preheating your oven to 375 degrees Fahrenheit (190°C). Generously grease a 13×18 inch baking pan with nonstick cooking spray. For easy removal and cleanup, line the greased pan with a piece of parchment paper, leaving a slight overhang on the sides.

Step 1: Preparing the baking pan with parchment paper.

STEP TWO: Combine Wet Ingredients for the Cookie Dough. In a large mixing bowl, using a stand mixer with the paddle attachment or a hand mixer, cream together the softened unsalted butter and granulated sugar until light and fluffy. Once combined, beat in the vanilla extract and eggs one at a time, ensuring each egg is fully incorporated before adding the next. This creates a smooth, well-aerated base for your cookies.

STEP THREE: Mix Dry Ingredients and Form the Dough. In a separate medium bowl, whisk together all the dry ingredients: all-purpose flour, salt, and baking powder. Gradually add this flour mixture to the wet mixture in your large bowl, mixing on low speed until just combined. Be careful not to overmix, as this can lead to tough cookies. Once the dough comes together, spread it evenly into the prepared baking pan. For best results, use your hands or a rubber spatula to press the dough into an even layer. Bake for 10-15 minutes, or until the edges are lightly golden brown and a toothpick inserted into the center comes out clean.

Step 2-3: Mixing the cookie dough in a large bowl.

STEP FOUR: Prepare the Fluffy Frosting. While your cookie bars are baking or cooling, begin preparing the frosting. In a clean large bowl, cream together the softened unsalted butter, shortening, your chosen extracts (vanilla and/or almond), and a pinch of salt using an electric mixer on medium speed. Gradually add the powdered sugar, one cup at a time, alternating with splashes of milk, mixing until the frosting becomes wonderfully light, smooth, and fluffy. If desired, you can add a few drops of food coloring to achieve a vibrant hue.

Step 4: Preparing the frosting in a mixing bowl.

STEP FIVE: Frost and Decorate Your Cookie Bars. Once the sugar cookie bars have completely cooled (this is crucial to prevent the frosting from melting!), spread the prepared frosting evenly over the top. The best tool for a smooth, professional finish is an offset spatula. After frosting, unleash your creativity! You can add a generous layer of sprinkles, colorful candy bits, or even fresh fruit for a delightful garnish.

Frequently Asked Questions About Sugar Cookie Bars

  • Why are my frosted sugar cookies so dry? If you notice your cookie dough is dry and crumbly before baking, you can try adding a teaspoon of milk or water, one at a time, until the mixture just binds together. The most common reason for dry cookies after baking is simply overbaking. Keep a close eye on them in the oven! If your baked bars turn out a bit dry, don’t despair – a generous application of that rich, fluffy frosting can often help to moisten them up and make them delicious again!

  • How long can frosted sugar cookies last at room temperature? For optimal freshness and flavor, store your Frosted Sugar Cookie Bars in an airtight container at room temperature for up to seven days. This keeps them soft and delicious. If you need to extend their shelf life, they can be stored in the refrigerator for up to two weeks, or frozen for up to three months. When freezing, wrap them tightly in plastic wrap and then aluminum foil to prevent freezer burn.

  • Do frosted sugar cookies need to be refrigerated? Generally, no, frosted sugar cookies do not immediately require refrigeration. They are perfectly fine sitting on your counter in an airtight container for about a week, allowing them to remain soft and accessible for easy snacking. However, if you’re not baking the dough right away, it’s crucial to refrigerate your sugar cookie dough to keep it fresh and safe. Always refrigerate after the initial week at room temperature for longer storage.

  • How do you keep the middle of the cookie bars from sinking and ensure they are fully cooked? To prevent your sugar cookie bars from sinking in the middle, the key is to ensure they are thoroughly cooked. Look for signs of doneness: the edges of the bars should be lightly golden brown, and when you insert a toothpick or a small knife into the center, it should come out clean. An underbaked center is a common cause of sinking, so a little extra baking time (without overbaking) can make all the difference.

  • What’s the difference between butter and shortening in frosting? Butter is a dairy product, a mixture of fat and about 15-20% water, which gives frosting a rich, creamy flavor but can also make it less stable and prone to melting. Shortening, on the other hand, is 100% solid fat, typically vegetable-based. Because it contains no water and has a higher melting point, shortening provides significantly more stability and structure to frosting, making it thicker and less likely to sag or melt. Using both butter and shortening, as in this recipe, allows you to enjoy the delicious, classic buttery flavor while benefiting from the enhanced stability and firm texture that shortening provides.

Creative Substitutions for Your Sugar Cookie Bars

Don’t hesitate to get creative in the kitchen! When it comes to making substitutions in recipes, remember that adapting ingredients to suit your personal taste, dietary preferences, or what you have on hand is part of the joy of cooking. Make this recipe truly your own!

  • Almond extract alternatives: While almond extract provides a uniquely rich, sweet, and nutty flavor that beautifully complements vanilla, it can certainly be interchanged with pure vanilla extract for a more classic taste. For a similar sweet, nutty profile, you might also consider trying hazelnut extract. Other options include lemon, orange, or even peppermint extract for seasonal variations.

  • Shortening substitutes: Although I don’t typically recommend a full substitution for shortening in this frosting due to its unique stability benefits, in a pinch, you can use an equal amount of butter (1 cup shortening = 1 cup butter). Be aware that an all-butter frosting will be softer and may melt more easily, especially in warmer environments. You might need to add a bit more powdered sugar to achieve a firmer consistency, or chill the frosted bars longer.

  • Milk alternatives in frosting: Milk primarily acts as a thinning agent in the frosting, allowing you to achieve the perfect spreadable consistency. Therefore, almost any liquid can work! Feel free to use heavy cream for an even richer frosting, or simply water if you’re out of milk. For flavored frostings, you could experiment with a small amount of lemon juice for a tangy kick, or even cold coffee for a subtle mocha flavor.

Top Tips & Tricks for Perfect Frosted Sugar Cookie Bars

Achieving perfect Frosted Sugar Cookie Bars is easier than you think with these helpful tips and tricks:

  • Invest in a Mixer: This recipe involves a fair amount of creaming and mixing, especially for the frosting. I highly recommend using a stand mixer with a paddle attachment. It will save your arm muscles and ensure your ingredients are thoroughly combined and aerated for the best texture.

  • Prepare Dough Ahead of Time: One of the greatest conveniences of this recipe is its make-ahead potential. You can prepare the cookie dough up to three to five days in advance and keep it tightly wrapped in plastic in your refrigerator. For even longer storage, the dough can be wrapped and frozen for up to three months. Just thaw in the fridge before baking.

  • Proper Storage for Freshness: To keep your frosted treats soft and delicious, store them in an airtight container (like Tupperware or a resealable bag) at room temperature for up to a week. If you need to store them for a few more days beyond that, transfer them to the refrigerator.

  • Perfect for Gifting & Selling: These Frosted Sugar Cookie Bars are ideal for bake sales, potlucks, or as thoughtful homemade gifts. Package individual bars in clear cellophane bags tied with a ribbon for an attractive presentation for work events, school parties, or simply sharing with friends and neighbors.

  • Creative Shapes (and Leftovers!): While designed as bars, you can also use cookie cutters on the baked and cooled sheet of cookie bars to create fun shapes – think Valentine’s Day hearts, spooky Halloween pumpkins, or festive stars. Don’t waste the leftover pieces! Crumble them over ice cream, yogurt, or use them as a topping for other desserts for an easy and yummy bonus treat.
