Sugar cookie bars have all the delicious traits of classic vanilla cookies, but in a cookie bar! These easy frosted sugar cookie bars can be made for any occasion, and are finished with a simple buttercream frosting.

Hi hi! Just popping in to share the recipe for these super easy sugar cookie bars! These soft and chewy frosted sugar cookie bars are made a cookie bar version of my classic vanilla cookies.
These super simple sugar cookie bars are finished with an easy buttercream frosting and sprinkles, to make them perfect to suit any occasion. I love making them for a crowd as the recipe scales beautifully!


How to convert a cookie recipe into a bar recipe
This sugar cookie bar recipe is super simple - it is essentially a batch of classic vanilla cookie dough pressed into a pan and baked rather than being baked into individual drop cookies.
Baking a cookie bar into a pan not only saves you time but gives you a whole different textural experience - the middle pieces stay soft and chewy, while the outside edges get nice and crinkly, so you can choose what piece you get.
I often convert my homemade cookie recipes into cookie bar recipes - usually the only tweak I found I needed to make in the recipe testing process is reducing the leavening agent a little to stop them being as puffy, and deciding what pan to use. Here is how I typically decide pan size (for my recipes at least)
- If it is a larger cookie recipe such as my vanilla cookies, I will choose a 9x13" pan. I tried this sized batch in a 9" square pan and it did not go well.
- If it is a smaller batch recipe like my brown butter chocolate chip cookies or my M&M cookies, I will put it either into a 9" pan or an 8" pan (see my chocolate chip cookie bars and my M&M cookie bars). I tend to go for 8" for recipes like this as I like them slightly thicker, but if you want them thinner and a little crispier, go for a 9" pan.



The most satisfying part - frosting!
I finished the cooled cookie bars off with a super simple American buttercream frosting (butter, powdered sugar etc) - this is totally an optional step, but I will never turn down the opportunity to do some frosting swooping.
I tinted the buttercream with a little gel food coloring and finished the cookie bars off with sprinkles. You can really choose your own adventure here and do what you like. If you wanted a nostalgic chocolate frosting you could use my brownie frosting recipe (you may have to scale it up a little). You could also add on a cream cheese frosting if you wanted, or add some freeze dried raspberry powder like I did for this funfetti cake. You do you here.
If you don't want to frost the sugar cookie bars you can leave them plain and they are also delicious - just give the surface of the sugar cookie batter a generous sprinkle with granulated sugar before it goes into the oven. I like to do this regardless of if I am frosting them or not. You could also frost half of them and leave half of them plain, I cannot stress enough that this is a choose your own adventure situation.

How to get clean cuts on a cookie bar
I have a few tricks to doing this which I use for my brownie recipes especially. If you don't care about clean cuts on your baking then you do you here, but here is how I get nice clean cuts on my baked goods:
- Chill the cookie bars slightly. Yes, I also chill my cookie bars, just a little bit. This gives the frosting time to set and to also crust over, which gives a nice clean cut. You can also leave it at room temperature uncovered for a little to help it crust, but chilled will give you the cleanest cut here.
- Use a ruler. This is the only way I find to get nice even cuts - otherwise no matter how well I think I have done at eyeballing it, my cookie bars come out wonky.
- Use a sharp knife. I use a chef's knife that has a huge 12" blade on it which means I can do cuts all in one go. Having a super sharp knife helps a lot too though.
- Wipe the blade between cuts. This seems super annoying but I promise to get a nice clean cut on your sugar cookie bars, wiping the blade between each cut will help a lot here.

Description
Sugar cookie bars have all the delicious traits of classic vanilla cookies, but in a cookie bar! These easy frosted sugar cookie bars can be made for any occasion, and are finished with a simple buttercream frosting.
Ingredients
Sugar Cookie Bars
- 225g unsalted butter, at room temperature
- 300g granulated sugar
- 1 large egg (50g not including the shell), at room temperature
- 1 tsp vanilla bean paste or vanilla extract
- 320g all-purpose flour
- 1 tsp kosher salt
- ¼ tsp baking soda
- Granulated sugar for the top
American Buttercream Frosting
- 170g unsalted butter, at room temperature
- 380g powdered sugar, sifted
- 1 tsp vanilla bean paste or vanilla extract
- ½ tsp salt
- 2 tbsp cream or milk, plus more if needed
- Gel food coloring if desired
- Sprinkles for finishing
Instructions
SUGAR COOKIE BARS
- Preheat the oven to 350°f / 180°c. Grease and line a 9x13" (20x30cm) pan with parchment paper, leaving a little overhang or piece sticking out so that you can remove the cooled cookie bars once done.
- In the bowl of a stand mixer fitted with the paddle attachment or using a handheld electric mixer, cream the butter and sugar together on high speed until light and fluffy. Add the egg and vanilla and mix to combine. Sift together the flour, salt, and baking soda in a small bowl. Add to the mixer, and mix until just combined.
- Transfer the cookie dough to the prepared pan, and spread out into an even layer using an offset spatula.
- Sprinkle the top of the cookie bars with granulated sugar if desired.
- Bake the sugar cookie bars for 20 to 25 minutes, until they are lightly golden brown on the tops and the center looks set. They will crinkle a little around the edges of the pan and the cookie bars will deflate slightly when removed from the oven.
- Remove the cookie bars from the oven and place the pan on a wire rack to cool completely.
AMERICAN BUTTERCREAM FROSTING
- In the bowl of a stand mixer fitted with the paddle attachment, whip the butter, vanilla bean paste and salt until pale and creamy. Sift in the powdered sugar, and mix on medium speed until well combined.
- If needed, add cream a tablespoon at a time, until the frosting is light and fluffy, and a spreadable consistency. Add gel food colouring until the desired colour is reached.
- Run the mixer on low speed for 2-3 minutes to help remove any air bubbles from the frosting. You will need to use the frosting immediately or place a piece of plastic wrap directly against the surface to stop it from crusting.
- Remove the cooled cookie bars from the pan using the parchment paper and place onto a cutting board or serving platter.
- Transfer the frosting to the cookie bars and swoop it on using the back of a spoon or an offset spatula. Add sprinkles if you like.
- Chill the cookie bars just until the frosting is set to help cut them into clean pieces. Cut into pieces with a sharp knife, wiping the knife between cuts.
- Store cookie bars in an airtight container in the fridge or at room temperature for up to five days.
Notes
These sugar cookie bars are great because you can make them ahead of time and store in an airtight container either at room temperature or in the fridge, depending on how cool your kitchen is.
I haven't tried freezing the cookie bars themselves, but you could probably freeze the baked cookie bars before you frost them in an airtight container - I tend to not freeze frosting once it has been applied as it is better if you can re whip it before it goes onto the bars.
If you only have salted butter that is fine - I use unsalted butter in my recipes as I have a global audience and butter is salted differently worldwide. Just omit the salt in the recipe if you are using salted butter.
If you would like to add additional extracts to your cookie bars go ahead! I don't personally like almond extract but I know a lot of people do, so if that's your thing, then go for it. You could also rub some lemon zest into the sugar before starting to make the cookie bars, which would give them a lovely subtle lemon flavor.
You could also add sprinkles to the mix like I did with my funfetti cookies - now that I think about it i'm bummed I didn't do it earlier, and now need to try this asap.

Soooo good 10/10

I have baked these three time since Christmas(chronically ill with fibromyalgia so wanted one large cookie to decorate as opposed to cutting and decorating 40 tiny ones) The recipe is easy to follow and absolutely delicious. Crispy edged and slightly chewy centers and lightly frosted they were very delicious and tasted like my childhood. So far I used butter but I'll be trying the recipe with plant based butter this weekend for my mostly dairy free son who gets eczema flare ups from dairy.
Jacqueline Shepherd says
I've had my eye on these for a while and finally baked them this weekend. They were DELICIOUS and such a hit with my friends! I also love that you can be so versatile with the colors and make them to match any theme/occasion!
Lauren says
Delicious! Big hit in our household
nicolette Limbrick says
Loved the slice went down a treat with the new mum i made it for too thanks !! Simple and very pretty without being too overly sweet
Nico
Steph says
These have so many 5 star reviews and deserve EVEN MORE HYPE! Super quick and easy to make and big hit. I find they crust over enough overnight to stack them with layers of parchment or wax paper between which makes transporting them extra easy.
Janna says
Has anyone tried storing these in the freezer or fridge for a longer shelf life? I want to make them ahead of time for a party and I was hoping that freezing might preserve freshness?
Erin Clarkson says
Hi! Yes you can make them ahead and freeze - I would leave them unfrosted though and frost once they are thawed 🙂
Tanya says
I have frozen them frosted with sprinkles and they are just as good as fresh baked.
I have frozen them two different ways.
Cut into small squares and cut the whole cookie in half.
I feel the trick to keeping them fresh when freezing is to let the frosting crust over, stack between parchment paper, put the cookies into freezer bags and then put them into a plastic container with a lid.
When you are ready to eat them, take them out of the freezer and let them come to room temperature.

Hi Erin,
I made these for Easter and they were a big hit with my family. So easy to make. I will be making them again. Thanks for the great recipe and wonderful blog.
Erin says
These are so delicious and nostalgic! Thank you for the recipe!
Monique says
This recipe is a favourite of mine. It involves super simple ingredients that I already have in the pantry. Always goes down a treat at a shared morning tea. No-one needs to know about the row I keep home for myself 😂
Ashley says
Wow!!! What a delicious recipe! Made these for my husband and it’s his new favorite alongside the small batch chocolate chip cookies recipe. They came out exactly as described. Will be making this a staple.
Kate says
I make this regularly, it’s so easy and such a hit. I’ve been adding freeze dried raspberries to the icing to make it pink - delicious!
Julie Baker says
These were absolutely delicious and easy to make! I wanted something simple and quick to bake for a party and these were a big hit!
Chocoholic says
This were so quick and easy and delicious!
Fiona says
I’ve made this many times now! Super easy and yum, I do it with the ‘poo icing’ (or super easy brownie icing recipe) instead which makes it more time effective for me to make as a family treat. Easily made dairy free too with swapping out butter with margarine.
Lynette says
Just made these! Absolutely delish! Recipe was perfect, I love when something tastes exactly as you imagine it will! Thank you!
cali says
hi erin! could I half this recipe and make it in an 8x8 pan?
Erin Clarkson says
Hi! I have a pan size calculator on my website which will do the maths for you on scaling! 🙂
Pip says
Yum! Easy to make and delicious. Thanks for the warning it deflates while cooling otherwise there’d’ve be some panic. Used a bit of raspberry liquid milkshake syrup to colour + flavour the icing and now I want to make it again with lime.
Kristin Rogers says
Perfection. Excellent cookie to buttercream ratio. Really went for it with the sprinkles too bc why not? Love the measurements in grams. So much easier to measure with a kitchen scale. And best results with precise measures.
Erin Clarkson says
I loveeeee these! Mega unicorn vibes! So happy you loved
Colleen Pagaard says
I've made these or a variation of these at least half a dozen times and they literally. Never. Fail. So easy, so much reward for so little effort. I've had the best feedback from adding dried cranberries and orange zest, and icing with a simple orange drizzle. Fan-freaking-tastic.
Steph Carr says
So yummy! Used this recipe to make Olympics themed bars for our summer olympics watch party. My friends dusted them off within minutes!
As always, super detailed post and recipe is clear and easy to follow. Thanks!!!
Erin Clarkson says
Ahhh they are so so cute! Perfect!
Kelsey Alexander says
These are fantastic. But I find it nearly impossible to spread the dough even with the spatula. Is there a trick?
Erin Clarkson says
Hi, crumble the dough into the pan first and then pat it down. Make sure that your pan is greased underneath the parchment paper so that you have some resistance to go against
Emily says
Can you tell me if I have the conversions correctly converted on the following ingredients? I do not have a scale I use for baking.
Dough:
1 + 1/16 cup butter (225g)
1 + 3/4 cup sugar (300g)
2 + 1/2 cup AP flour (320g)
Frosting:
3/4 cup butter (170g)
2 + 7/8 powdered sugar (308g)
Erin Clarkson says
Hi Emily, I don't have the conversions sorry as I only test in grams so if you're comfortable using those measurements go ahead but those aren't conversions I would use!
D says
I do agree with Erin, scale is more accurate than volume measurements. Most scales have both volume/grams measurements and are inexpensive. Should check out Amazon for kitchen scales with volume/gram conversions.
D says
Conversions for Emily:
DOUGH:
225g butter = tad less than 2 sticks butter or 1 cup
300g granulated sugar = 1-1/2 cups
320g all-purpose flour = 2-2/3 cups
FROSTING;
170g butter = 1-1/2 sticks butter or 3/4 cup
308g powdered sugar = tad more than 2-1/2 cups
Erin Clarkson says
Please note that these quantities haven't been tested - if people use them and the recipe doesn't work that's on them, not me!
Lilly says
I made these for my son’s birthday party and they were the biggest hit!! I added some Dutch cocoa powder to the icing recipe (I measured with my heart, I’m sorry) and they turned out incredible! Thank you Erin for sharing your wonderful recipes 🙂
Trish says
These are so great! Couldn’t be easier and were a fun party dessert.
Erin says
Made these with a hand mixer as my Kitchenaid broke. They came out perfectly. The cookie is so tender and I love the generous frosting to cookie ratio.
Rachelle says
Honestly, can’t say enough good things about these bars. Not too sweet, so soft but gods their shape. I did use cream cheese buttercream instead of regular American buttercream which I also think added a nice little tang.
Mary says
Have made this recipe several times and it's so easy but so good!
Today I made it for a GBB drop to the local hospice
Thanks Erin!
Abbie P says
Made these for the kids and have carried on making them mostly for myself ever since usually hiding them from said kids because they are SO DARN DELICIOUS! Soft base and the icing is just 11/10. Love love love
Kendra Lombardi says
I think I died and went to cookie heaven. Absolutely delicious!! We definitely used fake butter too! 😉We didn’t even frost them and they were so damn good! Erin, your recipes are epic and you are my “got-to” when needing any baked goods! Thank you!!
Katherine says
The last two recipes I made of yours that have salt and baking soda were very salty (at first I thought it was the baking soda but now I think it's the salt). I'm in NZ and using iodized table salt. Having just googled kosher salt, I'm guessing that's my issue?
Erin Clarkson says
Hi! Yep table salt is twice as salty as kosher salt 🙂
Drew H says
I made these to bring into work for 'cookie week' and here is some of the feedback I received:
"Those were some dangerously good cookies"
"I loved the cookies you brought in today"
"Dem sugar cookies were legittt"
"Absolute fire"
"I'm breaking my diet just to eat this cookie"
"Commuting into work today was worth it just for this cookie"
Erin Clarkson says
Haha yusss I love it!
Olivia says
Oh my gosh, this recipe is fantastic! So simple and quick, but also absolutely delicious. 5 stars, no notes.
Deb says
I cannot stop making these! They’re simple but taste like you worked really hard. And the way you can experiment with different colors, flavor extracts, and sprinkles in the frosting makes it feel like a new bar every time! Instant classic!!
Madison says
I can't remember if I made a comment already so I'm making another one to be sure I've sung the praises of these bars! We call this recipe "cookie cake" in our house and we make it for so many special occasions (birthdays, potlucks, holidays, etc). They are soft, chewy and the slight hit of salt ensures they aren't oversweet. They are so simple to make and so much fun to decorate. Three cheers for cookie cake!
Hannah May Gunther says
These are soooo good! I made an icing with Bonne Maman rhubarb and strawberry icing to go on top - it was the perfect combo!
