Easy Frosted Sugar Cookie Bars
The Easiest Way to Enjoy Classic Holiday Sugar Cookies
There is no denying that classic cut-out sugar cookies are a beloved holiday tradition, but let’s be honest: they are also incredibly time-consuming. Between chilling the dough, rolling it out to the perfect thickness, stamping out individual shapes, and meticulously frosting each one, it can easily turn into an all-day project. If you are craving that nostalgic, buttery bakery flavor but simply do not have the time (or the patience) for the traditional method, these frosted sugar cookie bars are the ultimate lifesaver.
By baking the dough in a single square pan, you get all the classic holiday flavor you love with a fraction of the effort. These bars bake up incredibly thick, soft, and dense, with a texture that is wonderfully chewy in the center. Because the dough does not need to hold a specific shape, there is absolutely zero chilling or rolling required. You simply mix, press, and bake.
The crowning glory of this dessert, however, is the thick layer of homemade pink buttercream frosting. It is rich, sweet, and perfectly complements the delicate vanilla and almond notes in the cookie base. Topped with a heavy shower of festive holiday sprinkles, these squares look gorgeous on any dessert table and are incredibly easy to slice and serve to a crowd. Prepare to have a new go-to recipe for last-minute holiday parties!

Ingredients
For the Cookie Bars
- Unsalted butter: Must be softened to room temperature so it creams perfectly with the sugar, creating a light and tender crumb.
- Granulated sugar: Sweetens the cookie base while keeping the color beautifully pale.
- Large egg: Acts as the binder. Ensure your egg is at room temperature so it incorporates smoothly without breaking the butter mixture.
- Vanilla extract: A staple for that classic sugar cookie flavor profile.
- Almond extract: The secret ingredient! Just a tiny splash provides that iconic, slightly nutty flavor that distinguishes a good sugar cookie from a great one.
- All-purpose flour: Gives the bars their structure. Be sure to spoon and level your flour so the dough isn’t too dry.
- Baking powder: Provides just enough lift to keep the bars soft and slightly cakey.
- Salt: Balances out the sweetness of the thick buttercream frosting.
For the Buttercream Frosting
- Unsalted butter: Again, softened to room temperature to guarantee a silky, lump-free frosting.
- Powdered sugar: Also known as confectioners’ sugar. It provides the structure and sweetness for the buttercream.
- Milk: Just a splash to thin the frosting into a perfectly spreadable consistency.
- Vanilla extract: Adds warmth and flavor to the sweet icing.
- Pink food coloring: A single drop gives the frosting a beautiful, bakery-style pink hue. You can use liquid or gel.
- Holiday sprinkles: Classic jimmies or nonpareils add a wonderful crunch and festive flair.
Step-by-Step Instructions
Step 1: Prep the Baking Pan
Begin by preheating your oven to 350°F (175°C). Take a standard 9×9 inch square baking pan and line it carefully with parchment paper. Make sure to leave a couple of inches of parchment hanging over the edges of the pan. This creates a highly convenient “sling” that allows you to lift the entire block of baked cookie out of the pan later for perfectly clean slices.
Step 2: Cream the Butter and Sugar
In the bowl of a stand mixer fitted with the paddle attachment (or a large bowl using an electric hand mixer), combine the softened unsalted butter and granulated sugar. Beat them together on medium-high speed for about two to three minutes. The mixture should look visibly lighter in color and very fluffy.
Step 3: Add the Wet Ingredients
Once the butter and sugar are perfectly creamed, scrape down the sides of the bowl with a rubber spatula. Beat in the room-temperature egg, the vanilla extract, and the almond extract until everything is smooth and well combined.
Step 4: Incorporate the Dry Ingredients
Turn your mixer down to its lowest speed setting. Add the all-purpose flour, baking powder, and salt. Mix just until the dry white streaks of flour disappear into the dough. It is very important not to overmix at this stage; overworking the dough will develop the gluten and result in tough, dense bars instead of soft, tender ones.
Step 5: Press and Bake
Transfer the thick cookie dough into your prepared baking pan. Because the dough is somewhat sticky, it can be helpful to lightly flour your hands or spray a rubber spatula with a little non-stick cooking spray. Press the dough firmly and evenly into the bottom of the pan, making sure it reaches all four corners.
Bake in the preheated oven for 15 to 18 minutes. You want to pull them out when the edges are just starting to turn a light golden brown, but the center still looks slightly soft and pale. Let the bars cool completely in the pan while resting on a wire rack.
Step 6: Whip the Buttercream
While the cookie base cools, make your frosting. In a clean mixing bowl, beat the softened butter on medium-high speed for a full 2 minutes until it is incredibly creamy and pale. Gradually add the powdered sugar, milk, vanilla extract, and a drop of pink food coloring. Once the sugar is incorporated, turn the mixer to high and beat for 3 full minutes. This whips air into the frosting, making it exceptionally light and fluffy.
Step 7: Frost and Slice
Ensure the cookie block is 100% cooled to room temperature before proceeding. If it is even slightly warm, your buttercream will melt into a puddle! Use an offset spatula to spread the thick layer of pink buttercream evenly across the cookie block. Immediately top with a generous shower of holiday sprinkles before the frosting sets. Use the parchment paper overhang to lift the entire block out of the pan, place it on a cutting board, and slice it into 16 even squares.
Expert Cooking Tips
- Use the parchment paper sling: Do not try to slice these bars while they are still in the pan. The parchment overhang lets you lift the entire slab onto a cutting board, guaranteeing clean, sharp, bakery-style edges.
- Do not overbake: To achieve that soft, chewy, melt-in-your-mouth texture, the center of the pan should still look a tiny bit underbaked when you pull it from the oven. It will continue to set as it cools in the hot pan.
- Cool completely: Buttercream is exactly what it sounds like—mostly butter. If the cookie is even slightly warm to the touch, the frosting will melt and slide right off the edges. Be patient and wait for it to cool entirely.
- Whip the frosting well: Do not rush the buttercream! Beating the frosting for a full 3 minutes at the end incorporates necessary air, transforming it from a dense sugary paste into a light, airy, melt-in-your-mouth topping.
- Wipe your knife between cuts: For the cleanest, most professional-looking slices, wipe your knife completely clean with a damp paper towel after every single cut.
Variations to Try
- Cream Cheese Frosting: If buttercream is too sweet for your taste, swap it out for a tangy, rich cream cheese frosting to balance the sweetness of the cookie base.
- Lemon Sugar Cookie Bars: Swap the almond extract for a tablespoon of fresh lemon juice and a tablespoon of lemon zest in the dough for a bright, citrusy twist.
- Funfetti Style: Gently fold half a cup of colorful jimmies directly into the cookie dough before pressing it into the pan to make funfetti bars.
- Brown Butter Base: Brown the 1/2 cup of butter and let it solidify back to room temperature before creaming it with the sugar for an incredibly deep, nutty, caramel flavor profile.
What to Serve With Frosted Sugar Cookie Bars
These thick, decadent bars are incredibly satisfying and pair perfectly with your favorite cozy drinks. Serve them with:
- A tall, ice-cold glass of milk.
- A freshly brewed mug of dark roast coffee to balance the sweet buttercream.
- Warm apple cider garnished with a cinnamon stick.
- A festive dessert spread alongside fudgy brownies and salty pretzel treats.
Storage & Reheating
Refrigerator
You can store these cookie bars in an airtight container at room temperature for up to 3 days. However, if your kitchen is very warm, the buttercream may become too soft. In that case, store them in the refrigerator in an airtight container for up to 5 days. Let them sit on the counter for 15 minutes before serving so the frosting softens slightly.
Freezer
These bars freeze beautifully, either frosted or unfrosted. To freeze frosted bars, slice them, place them on a baking sheet until the frosting is frozen solid, and then transfer them to a freezer-safe container with wax paper between the layers. They will keep for up to 3 months. Thaw at room temperature.
Reheating
Because they are topped with a thick layer of buttercream, you should never reheat these bars in the oven or microwave. Enjoy them at room temperature or slightly chilled!
Frequently Asked Questions
Can I bake these in a 9×13 inch pan instead?
This specific recipe is scaled for a 9×9 inch pan to yield thick, bakery-style bars. If you stretch this exact dough into a 9×13 pan, the bars will be very thin and easily overbaked. If you want to use a 9×13 pan, you need to double all of the ingredients for both the dough and the frosting.
Why is my dough so crumbly and not coming together?
If your dough is too crumbly to press into the pan, you likely measured your flour incorrectly. Scooping flour directly with a measuring cup packs it down, resulting in too much dry ingredient. Always use the spoon-and-level method. If it’s just a little dry, you can knead it slightly with your hands to help the butter bind it.
Can I use store-bought frosting to save time?
Absolutely! While homemade buttercream provides the best texture and flavor, a tub of store-bought vanilla or cream cheese frosting works perfectly in a pinch. Just give the store-bought frosting a quick whip with a hand mixer before spreading it to lighten the texture.
Do I have to use almond extract?
You do not have to use almond extract, but it is highly recommended. It is the secret ingredient that gives sugar cookies their distinct, nostalgic “bakery” flavor. If you have an allergy or simply dislike the taste, you can omit it and add an extra half teaspoon of vanilla extract instead.
How do I get perfectly clean slices without smearing the frosting?
The secret to pristine slices is chilling the cookie block. Once you have frosted the cooled bars, place the entire pan in the refrigerator for about 30 minutes to let the buttercream firm up. Then, lift the block out using the parchment paper and slice with a large, sharp knife, wiping the blade clean after every cut.
Final Thoughts
When the holiday rush sets in and you simply don’t have the time to roll and cut out individual cookies, these frosted sugar cookie bars are the ultimate baking hack. They deliver all the buttery, nostalgic flavor and beautiful festive colors you want, but they come together in a fraction of the time. The combination of the soft, chewy cookie base and that impossibly fluffy pink buttercream is guaranteed to make these a massive hit with both kids and adults alike. Grab your favorite sprinkles and enjoy the easiest holiday baking project of the year!
