How to Make Christmas Sugar Cookie Bars
Step 1: Prep Your Pan and Oven
Begin by preheating your oven to 350°F (175°C). Line a 9×13-inch baking dish with parchment paper, letting the edges hang over slightly for easy lifting. If you’re out of parchment, a good greasing works too. This first step means your bars won’t stick and makes clean-up a breeze.
Step 2: Cream Butter and Sugar
In a large mixing bowl, beat the softened butter and granulated sugar together until the mixture is visibly lighter in color and nice and fluffy. This aerates the dough, yielding those coveted soft, melt-in-your-mouth bars.
Step 3: Add Egg and Vanilla
Crack in the egg and pour in the vanilla extract. Mix on medium speed until everything’s fully incorporated—watch as the batter gets creamy and glossy. This is where the sugar cookie magic starts building!
Step 4: Mix Dry Ingredients Separately
In another bowl, whisk together your all-purpose flour, baking powder, and salt. This step ensures even distribution, so every bite of your Christmas Sugar Cookie Bars rises just right and tastes perfectly balanced.
Step 5: Combine Wet and Dry Mixtures
Gradually add the dry ingredients to your wet mixture, mixing on low and scraping the sides as needed. Stop as soon as a soft, uniform dough forms—overmixing can lead to tough bars, so gentle is the way!
Step 6: Press Dough Into Pan
Transfer the dough to your prepared pan. Use clean hands or an offset spatula to press it evenly to the edges. Aim for an even layer so every bite bakes up with the same blissful texture.
Step 7: Bake
Slide your pan into the preheated oven and bake for 18 to 22 minutes. The edges should turn lightly golden while the center sets, but don’t overbake—these bars are best soft. Let them cool completely in the pan before moving on.
Step 8: Decorate
Once cooled, spread your vanilla buttercream frosting generously over the cookie base, and get creative with your favorite holiday sprinkles or sanding sugar. This is the festive finish that makes Christmas Sugar Cookie Bars so joyful!
Step 9: Slice and Serve
Lift the bars out of the pan using the parchment paper, slice into even squares, and serve. Each slice is a delicious burst of holiday spirit!
How to Serve Christmas Sugar Cookie Bars
Garnishes
A generous scattering of holiday sprinkles or a dusting of sparkling sanding sugar is the ultimate finishing touch. If you’re feeling extra festive, you can even use tinted buttercream for fun color contrasts—think swirls of red, green, or even gold.
Side Dishes
Pair these bars with mugs of hot cocoa, spiced chai, or a good old-fashioned glass of cold milk. They also look lovely alongside a platter of other seasonal treats at your dessert table—think gingerbread men or chocolate crinkle cookies.
Creative Ways to Present
Arrange your Christmas Sugar Cookie Bars on a tiered stand for visual impact, or package individual squares in cellophane bags with a ribbon for the ultimate edible holiday gift. They’re also perfect for stacking in a festive tin for cookie swaps or handing out to neighbors.
Make Ahead and Storage
Storing Leftovers
Keep any leftover bars in an airtight container at room temperature for up to three days. They’ll stay soft and delicious, especially if you press a piece of parchment over the top to keep them from drying out.
Freezing
If you want to get ahead on holiday prep, you can freeze the unfrosted cookie bars. Simply wrap the cooled slab tightly in plastic wrap and foil, then freeze for up to two months. When ready to serve, thaw, frost, decorate, and enjoy!
Reheating
While these bars don’t really need reheating, you can bring them back to that just-baked coziness by letting them sit at room temperature for about 30 minutes—or give an individual bar a five-second zap in the microwave for a gooey, buttercream-soft treat.
FAQs
Can I make Christmas Sugar Cookie Bars ahead of time?
Absolutely! You can bake the cookie base one or even two days ahead; just keep it tightly covered. Frost and add your sprinkles the day you plan to serve for the freshest look and taste.
Do I have to use homemade frosting?
Homemade vanilla buttercream adds that tender, real-deal vibe, but if you’re in a crunch, a good-quality store-bought frosting will work. Feel free to flavor or color your frosting to match your favorite holiday hues!
Can I customize the decorations?
Definitely! Part of the fun with Christmas Sugar Cookie Bars is getting creative. Try colored sugars, crushed candy canes, or even edible glitter for extra sparkle.
Can I make these gluten free?
Yes, you can substitute a good 1:1 gluten-free all-purpose flour blend. Your bars may have a slightly different texture, but they’ll still be every bit as delicious and festive.
Why do my bars seem dry or crumbly?
That usually happens from overbaking or too much flour. Be sure to measure your flour correctly (spoon it into the measuring cup and level off) and keep an eye on baking times for the ideal soft texture.
