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!
