Lemon curd cookies are a life-changing thing, I can promise you that. First, I made the lemon poppy seed copycat cookies from Crumbl and they were absolutely adored by everyone.
So naturally now, I feel like it’s time to make the Crumbl lemon bar cookies. The cookie base isn’t too crazy. Just a simple lemon butter cookie but the lemon curd topping will blow your mind!
This is the best lemon bar cookie recipe ever!
This Crumbl cookie was inspired by our favorite lemon bars, you know the ones with a custard lemon topping that is baked in the oven with the crust underneath.
The difference when it comes to this cookie though is that the curd will only be used as a topping instead of it being baked on the cookie.

Ingredients for this lemon bar cookie recipe
Here are the ingredients you will need to make this lemony cookie. Make sure to scroll down to the recipe card for the full detailed ingredient measurements.
- Butter– You can use salted or unsalted butter for this recipe.
- Granulated sugar & powdered sugar- The combination of both sugars will yield a super moist and chewy cookie.
- Egg– The egg is the binding agent. Make sure it is at room temperature.
- Butter vanilla emulsion– This will give our cookies that authentic buttery flavor you get from Crumbl cookies.
- Lemon flavoring– Can’t have a lemon cookie without the lemon flavoring.
- Lemon zest– The lemon zest will also add that extra zing to our cookies.
- Flour– AP flour works great here.
- Salt– Always use a little salt in your baked goods to balance out the flavors.
- Baking powder– This will give our cookies a little height.
- Lemon curd– You can either make homemade lemon curd or use store-bought. Both would work great but making it homemade would take a little more time since it has to set in the fridge for a few hours. The flavor of the homemade one is a million times better though!
Do I have to make homemade lemon curd?
No, you don’t. But I highly recommend it because it tastes a million times better than regular lemon pie filling.
It is tangier and lemony, and the creaminess is seriously unmatched. Plus it’s a great opportunity to practice making your own homemade lemon curd using my recipe.

Frequently asked questions – FAQ
WHAT IF MY COOKIES LOOK UNDERBAKED WHEN I PULL THEM OUT OF THE OVEN?
Crumbl cookies often look a tad bit underbaked when you pull them out of the oven. But don’t worry about that they will continue baking as they cool.
Make sure to let these cookies cool down before you top them with the curd.
How to store lemon bar cookies?
Since these cookies are meant to be served chilled, you can store them in an air-tight container in the fridge for up to 3 days.
You can store them for longer if they are unfrosted. They will last in an air-tight container in the fridge for up to 7 days. Once ready to enjoy, top them with the lemon curd and enjoy!
Can I freeze lemon bar cookies?
These cookies freeze beautifully. Keep in mind that I made this recipe with my homemade lemon curd recipe so I know that that curd will frost well.
I can’t guarantee that storebought or other recipes of lemon curd will set the same.
To freeze these cookies, flash freeze them on a flat surface for (baking sheet, plate…) for a few hours to set, then transfer to an airtight container and freeze for up to 2 months.
Once ready to enjoy, pull them out and let them thaw on a flat surface (baking sheet, plate…) in the fridge overnight or on the countertop for a few hours before enjoying!
How to make mini Crumbl lemon bar cookies?
To make the mini catering crumbl cookies, instead of making 7 large cookies, you will make 14 smaller ones.
And instead of baking them for 11minutes, bake them for 8 minutes. The rest of the steps are all the same and you will get cute little cookies out of this.

Is it important to use vanilla butter emulsion ? Because I can’t find it in Europe (only online) but I really want to cook those cookies because I adore lemon desserts❣️
Use vanilla extract 🙂 ! Enjoy!
I couldn’t find a usage for the lemon zest in the recipe.
When do I use it.
Also, if I made it without the lemon zest would it matter?
You mix it in with the egg, butter vanilla emulsion, and lemon extract in step 3. The lemon zest just adds a punch of flavor that would be a noticeable difference without the lemon zest.
Wow it’s really easy to make and the cookies turned out looking so good and absolutely delicious!
Thank you so much Phuong! I appreciate it.
You are my favorite for any dessert recipes! Thank you! Just a small error I noticed on the blog recipe; it says “Make the confetti cookies” under the instructions <3
Thank you for catching that Christine! 🙂
These turned out fantastic. The curd is just tart enough and the cookies are very soft. Perfect lemon bar in cookie form.
the vanilla butter emulsion?? did you mean the sugar butter emulsion??
No I mean vanilla butter emulsion. I use the one from Lorann’s! It makes the cookies so good. I was able to find mine at Walmart.
These cookies were so delicious! Perfect amount of lemon!
Just made these! Going to bring some to my friend who just lost her husband. My only critique is that the cookie itself did not have a lot of lemon flavor. It was very shortbread like but still had a soft bite to it. I will probably double the amount of lemon juice next time and maybe even add some lemon zest in the cookie dough. The true star is the lemon curd! Never thought it would be that easy to make homemade. It truly makes this cookie special. My family rates it an 8.5/10 🙂
Thanks for sharing!
Thank you for trying the recipe Bre! 🙂
Whisk in the egg, the vanilla butter emulsion, and the lemon extract and mix until combined.…
This is the first mention of vanilla butter emulsion, what is that?
The vanilla butter emulsion is a flavoring that doesn’t evaporate too much when you bake it making your cookies extra buttery and flavorful! That’s what Crumbl uses I heard. It can be found online or at Walmart!
Yummy! Fresh decadent tender cookie …and that lemon curd… Holy Smokes!
I found emulsions a while ago and have been using them in place of extracts in recipes ever since. Well worth the investment.
The cookie freezes very well, and the lemon curd needs to become a staple in my refrigerator! (Make it! You’ll see what I mean!)
Best lemon cookie I’ve ever made and/or tasted ❤
Oh! So glad you created these – how did you know this is just what I was hoping for?
Where in the recipe is the lemon zest supposed to be added?
In step 3 when mixing the egg, the vanilla butter emulsion, and the lemon extract 🙂
