Soft and chewy sugar cookie bars loaded with extra sprinkles and topped with thick vanilla frosting. And more sprinkles… of course.
These gorgeous pastel sugar cookie bars are about 5 years in the making. I’ve been dying to make sugar cookie bars with light ‘n sweet frosting for ages now. And I finally got around to it this past weekend. Let’s just call it my TV celebration treat. 🙂
In all their soft-baked, mile high frosting, sprinkles-to-the-max goodness… I can honestly say that these charming little treats were well worth the wait. I mean, just look at ’em.
The frosting is as thick as the cookie!! Have mercy.
Today’s recipe is as soft as my favorite soft-baked cookie, as chewy as my favorite blondie, and as sprinkly as my entire cookbook. You’ll find sprinkles in the cookie bar base AND on top of the frosting. Is there such a thing as too many sprinkles? Because I’m pretty sure we test those limits here on my blog.
To make the frosted sugar cookie bars ultra soft, I add a touch of cornstarch. Trust me on this! Think about it: often used as a thickening agent, cornstarch gives your gravy, pie fillings, soups, and glazes a more bodied and full texture. The same goes for your cookie dough – cornstarch will help your dough remain soft, thick, and puffy during the baking process. The small 1.5 teaspoons used is certainly a heavy lifter in this recipe!
To make the cookie bars ultra chewy, I add an extra egg yolk. I do this with a few of my cookie recipes because that little extra yolk adds so much moisture, tenderness, and chew to the cookie. And it does the same thing to the sugar cookie bar base in this recipe. You’re going to love their rich, tender texture.
What’s great about this recipe is that you don’t have to chill the cookie dough. Just press the dough into the pan and bake right away. Bake the bars in a square baking pan – 8 inch or 9 inch is fine. Only about 25 minutes. You want to slightly underbake the cookie bars in order to avoid the edges from getting too crispy and brown.
Allow the bars to cool completely before frosting. This will feel like an eternity.
If you’re the kind of person who eats cake just for the frosting, you’re going to love this recipe. And we would also get along very well. I may or may not have eaten the frosting off this cake before actually getting to the cake underneath. Uh, can you blame me?
You’ll use my basic vanilla frosting recipe for these bars. Classic, fluffy, and simple. I like to add a touch of salt to cut the frosting’s sweetness. With the sweet sugar cookie bar underneath, that tiny pinch of salt will help tame a sugar rush. Don’t get me wrong, these bars are still plenty sweet! Don’t bring them to your dentist.
And as you can see, the frosting layer is just as thick as the cookie layer. In some spots, even thicker – those were the best bites. The frosting recipe as written makes a ton, so don’t be afraid to frost the bars with a heavy hand.
Don’t want that much frosting? It’s ok, I forgive you. Feel free to halve the frosting recipe.
