Christmas Sugar Cookie Bars
These sugar cookie bars are adapted from my super popular M&M’S Christmas Cookie Bars and are just as delicious. There is something about frosted sugar cookies that immediately sets the mood for the holidays.
Start by mixing the sugar cookie dough in a stand mixer. Then add a cup of Christmas color sprinkles, not nonpareils. Save the nonpareils for sprinkling on top of the frosting. If you mix them into the sugar cookie dough, they will run and make the cookie dough a muddy brown color.
Line a 9×13 glass baking dish with foil and spray with non-stick cooking spray. Once they have cooled and been frosted, this will allow you to easily remove the entire pan and cookie bars and slice them evenly. Transfer the cookie dough to the baking pan. The dough should be thick.
Bake for 35 minutes, until edges are golden brown and middle is just set. Do not over bake, cookie bars will continue to cook as they cool.
Once the cookie bars are completely cooled, prepare the buttercream frosting. You can hurry the cooling process along by placing the pan in the refrigerator or freezer once they have cooled for about 30 minutes.
I like to use nonpareils on these Christmas Sugar Cookie Bars, but you can also use the same sprinkles you added to the sugar cookie dough.

Do you use salted butter?
I usually do because that’s what I have on hand. I haven’t noticed any difference between salted and unsalted butter in the cookie bars. ?
What a fun way to make sugar cookies look Christmas-ey! I am so excited to try this recipe!
These sugar cookie bars are one of our favorite treats for the holiday cookie platters!
My kids really loved this treat!! So good!
I have a question. These bars look mouth wateringly good, but I don’t really like sprinkles. Do they add anything to the taste? If I leave them out or use less, will it change the taste?
I LOVE your chocolate peppermint cookies. I may just have to work my way through all your cookie and bar recipes this Christmas! Thank you!
Thanks, Jan! I think they will be great without sprinkles!
