Easy Christmas Sugar Cookie Bars with Frosting are what I bake when I want the flavor of holiday cutout cookies without turning the kitchen into a flour storm. The dough presses into one pan, bakes up soft and buttery, and gives you neat little squares once the frosting sets.
The texture lands between a tender sugar cookie and a soft bakery bar. Almond extract gives that old-school cookie tray flavor, but you can leave it out if your family likes plain vanilla.
Let the base cool all the way before you frost it. That one patient step keeps the buttercream thick, smooth, and easy to slice.
Easy Christmas sugar cookie bar ingredients
The ingredient list is simple, so use fresh butter, good vanilla, and flour measured with a light hand. Softened butter should bend under a finger but not look shiny or melted.
- Unsalted butter. Gives the bars their tender crumb and lets you control the salt.
- Granulated sugar. Sweetens the dough and helps the edges bake lightly crisp.
- Egg. Holds the dough together and keeps the bars sliceable.
- Vanilla extract. Adds warm bakery flavor to both the dough and frosting.
- Almond extract. Gives the bars a classic holiday sugar cookie taste. Use less or skip it if you prefer.
- All-purpose flour. Builds the soft cookie base without needing to roll or chill the dough.
- Baking powder. Adds a small lift so the bars are tender instead of dense.
- Powdered sugar. Makes the buttercream smooth and fluffy.
- Milk or cream. Loosens the frosting so it spreads without tearing crumbs from the cookie base.
- Holiday sprinkles. Add color and a little crunch on top.
Bake, cool, frost, slice
- Mix the dough. Beat softened butter and sugar until creamy, then mix in the egg, vanilla, and almond extract. Add the dry ingredients just until the flour disappears.
- Press into the pan. Line a 9x13-inch pan with parchment, leaving overhang on two sides. Press the dough into an even layer so the corners bake at the same pace as the center.
- Bake until pale. Bake at 350 F until the edges are barely golden and the center no longer looks wet, about 15-18 minutes. Do not wait for deep browning.
- Cool completely. Let the pan cool on a rack until the cookie base is room temperature. Warm bars will melt the frosting.
- Whip the frosting. Beat butter until smooth, then add powdered sugar, vanilla, salt, and enough milk to make it fluffy and spreadable.
- Decorate and cut. Spread the frosting over the cooled bars, add sprinkles right away, then chill briefly before lifting out and slicing.
Measure flour with care
Sugar cookie bars are forgiving, but flour is where they can turn tough. Do not scoop straight from the bag with the measuring cup. That packs in extra flour and makes the dough crumbly before it even reaches the oven. Fluff the flour, spoon it into the cup, and level it with a flat edge. The dough should feel soft and moldable, almost like thick play dough.
A little caution matters with raw dough too. The CDC raw dough guidance notes that uncooked flour and eggs should not be tasted before baking. If you want a cookie tray with both bars and classic shapes, pair these with soft Christmas sugar cookies and keep the same frosting colors for a tidy platter.
The soft-center timing
The best moment to pull these from the oven is before they look fully golden. The edges should be set with just a hint of color, while the middle should look puffed and matte. The hot pan keeps cooking the base for a few minutes after it comes out. If you wait for the whole top to brown, the bars will slice neatly but taste dry.
Use a metal pan if you have one. Glass holds heat longer and can make the edges bake faster, so check early if that is what you are using. For an even richer version with a tangy topping, the site's sugar cookie bars with frosting are a good cousin to this recipe.
Frosting that slices neatly
The frosting should be fluffy, not runny. Start with softened butter and beat it until it looks lighter before adding powdered sugar. Add milk slowly. One extra tablespoon can take buttercream from spreadable to loose, especially in a warm kitchen. If it gets too soft, beat in more powdered sugar a spoonful at a time.
Spread the frosting with an offset spatula and stop before you scrape up crumbs from the cookie base. Sprinkles go on right away because buttercream crusts as it sits. For another frosted holiday bar with a bolder flavor, try these peppermint mocha cookie bars alongside the vanilla ones.
Decorating without fuss
You do not need piping bags to make these look festive. A smooth layer of white frosting and a heavy shower of red and green sprinkles is enough. For cleaner squares, chill the pan for 15-20 minutes after decorating. Then lift the bars out with the parchment and cut on a board.
If you want a more decorated look, divide a small spoonful of frosting into a separate bowl and tint it red or green. Drag thin lines through the white frosting before adding sprinkles. Keep it simple if the bars are traveling. Tall frosting swirls look pretty, but flat frosting packs better in cookie tins. These also fit nicely next to Christmas sugar cookie bars when you want a few styles from the same flavor family.
Storage and holiday trays
Store the sliced bars in an airtight container at room temperature for 2 days, or refrigerate them for up to 5 days if your kitchen runs warm. Separate layers with parchment so the frosting stays neat. The FoodSafety.gov FoodKeeper resource is helpful when you are planning bigger holiday storage.
For freezing, place the frosted bars on a tray until firm, then wrap and freeze. Thaw them in the refrigerator overnight. Sprinkles can bleed a little after freezing, so add a fresh pinch before serving if appearance matters. The flavor stays sweet, buttery, and very much worth making ahead.
FAQs
- Can I make Christmas sugar cookie bars ahead of time?
Yes. Bake the cookie base one day ahead, cover the cooled pan tightly, and frost it the next day. You can also frost and slice the bars up to 24 hours before serving if you store them in a single layer.
- Can I use cream cheese frosting instead?
Yes. Cream cheese frosting works well and gives the bars a tangier finish. Keep cream cheese frosted bars refrigerated, then let them sit at room temperature for 15-20 minutes before serving.
- Why are my sugar cookie bars dry?
Dry bars usually come from too much flour or overbaking. Spoon flour into the measuring cup, level it off, and pull the pan from the oven when the center looks set but still pale.
- How do I get clean slices through frosting?
Chill the frosted bars for 15-20 minutes, then use a large sharp knife. Wipe the blade between cuts so the frosting does not drag crumbs across the top.
- Can I freeze frosted sugar cookie bars?
Yes. Freeze the bars uncovered until the frosting is firm, then wrap them well and store them for up to 2 months. Thaw in the refrigerator and add fresh sprinkles if the colors bleed.
- Can I make these without almond extract?
Yes. Replace the almond extract with more vanilla extract. The bars will taste a little simpler, but still buttery and sweet.
