Buttery-soft sugar cookie bars topped off with a sweet buttercream frosting and plenty of colorful sprinkles! These cookie bars make a great treat any time of the year, but they’re easily customizable with festive sprinkles for the holidays or special occasions!
One more cookie recipe for you before Christmas! Ok, these don’t quite look like traditional cookies, but these sugar cookie bars are just as good, and if you’ve been putting off your holiday cookie baking you’ll be relieved to hear that these are a total breeze to make. There’s no chilling, cutting, or rolling required (I’m looking at you, classic sugar cookies), no scooping or waiting for your cookie sheets to cool to drop another batch into the oven, just spread your sugar cookie bar dough into the pan, bake it, and top with this sweet, simple 4 ingredient frosting. And with sprinkles, of course.
If you’re still in holiday baking mode, these sugar cookie bars can totally be decorated with festive red and green sprinkles for Christmas or colorful confetti sprinkles for New Years.
Obviously I went with the confetti sprinkles here 😍
With their thick, chewy bases and their sweet buttercream frosting, these sugar cookie bars all but melt in your mouth.
To make the bases so soft, I add a small amount (2 oz) of cream cheese into the dough. This not only makes the cookie bar base extremely soft, but it also gives it a great flavor and helps keep them from being too sweet. Make sure to allow your cream cheese (and butter) soften to room temperature so that they’ll completely cream together when you go to combine them.
This sugar cookie bar dough will be thinner than your average cookie dough, but it’s still pretty thick and sticky and can be hard to spread into a parchment-lined baking pan. You can just grease and flour your pan, but I really love to use the parchment as it makes it so easy for me to just lift the sugar cookie bars out of the pan once they’re done cooling and I can easily decorate and slice them (plus pan cleanup is super easy that way, too!). For me, it’s worth the trouble of wrestling the dough over the parchment paper.
I topped these sugar cookie bars off with a very simple buttercream frosting. The frosting is just four ingredients — butter, sugar, vanilla, and a pinch of salt for added flavor.
I typically tend to find buttercream to be almost too sweet for me, so I keep the frosting layer pretty thin. Even then I liked to cut these sugar cookie bars into even smaller pieces than you see in the pictures, as they’re still fairly sweet.
It probably doesn’t help that I like to go totally overboard with the sprinkles, either…
Alright, well I have a ton of gift wrapping to do and not a whole lot of confidence that I can finish it in 3 days… so wish me luck, and I hope that you love these sugar cookie bars!
