Easy Chilled Crumbl Lemon Bar Cookies (2025)

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.

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.

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!
