A few weeks ago, the middle child was "Superstar" at school. Lest this requires an explanation, over the course of the year, each first grader has a turn to be class Superstar for one week. The Superstar gets to share a poster with the class full of facts and photos of them. The Superstar's family is invited to eat lunch with him/her. The Superstar's parent(s) visit the classroom one afternoon to read a story. And the Superstar gets to bring a treat of some sort to share with the entire class.

Well, let me just say that after waiting all school year for his turn, my 7-year-old was WAY excited to finally have his moment week in the Superstar sun. And since his favorite desserts have always been lemony, he asked me to whip up some special lemon treats for the occasion.
I thought about making traditional lemon bars, but I was worried they'd be too messy. However, I like doing bars of some sort when baking for a large group, since slapping cookie dough in a pan is a lot faster than forming individual cookies.

I decided to take my ever-popular Chewy Snickerdoodle Bars recipe and see if it would translate to a lemon version. I omitted the brown sugar, cinnamon, and cream of tartar and added lemon juice, lemon zest, and a splash of lemon extract.
And while I've seen other lemon sugar cookie bars that were frosted, I wanted mine to be sugary on top. So I sprinkled the unbaked bars with a combination of granulated sugar and sparkling sugar, for simultaneous coverage and crunch. Then I crossed my fingers and popped 'em in the oven.

(Might I add here that I made a double recipe to have enough bars for all of my son's classmates and teachers -- meaning two 9- by 13-inch pans' worth -- so I really hoped the recipe was going to work on the first try!)
And...drumroll, please...I'm happy to report that my Lemon Sugar Cookie Bars turned out perfect! They're soft, light, and slightly chewy. The flavor is lusciously lemony but not overpowering. And the sugar cookie tops are sweet and crackly and crunchy (←my favorite part).
These were a hit with my son's class and they were a hit with our family at home (because having doubled the recipe, there were enough bars to save a few back for us as well...not by accident). But most importantly, these Lemon Sugar Cookie Bars were a huge hit with the Superstar himself! In fact, I think Mr. Resident Lemon Lover may just have a new favorite bar recipe... 😉

My bars are currently cooling, but there was just a change in plans for the birthday boy. Would these freeze well and if so how would I go about it?
Hi Kylie! Yes, you can freeze these. I would individually wrap the cooled bars in a doulbe layer of plastic wrap and then store them in an airtight container in the freezer for up to 3 months. You can just set them out at room temperature to thaw when you're ready.
These were so yummy. I cut the recipe in half and baked for 20 minutes in an 8X8 pan. Used the zest from two lemons and added some lemon powder to amp the lemon flavor. Ate half the pan immediately after a 20 minute cool 🙂
Can this recipe be cut in half and baked in an 8x8 pan?
Yes! You'll just need to check the bars for doneness sooner. 🙂
I just did this: cut the recipe in half and baked in an 8X8 pan for 20 minutes. I wasn't sure they were done but the toothpick came out clean. Perfection.
