Key lime pie cookies - Crumbl copycat

So technically in my mind this was my sign and let me tell you…!!! It was so exciting because I remembered this cookie tasting insanely good.

    This recipe is toooo good! But my filling turned out to be a little bit runny. Is there any way to fix it? Thanks!

    1. Chahinez says:

      Allowing the filling to chill will help it set better!

    Easter 2024… these were the bomb! I followed the recipe subbing vanilla as I did not have the emulsion. Very soft cookie, excellent taste and so yummy!

    I just need to figure out a way to store these layered in the fridge. I tripled the batch. One batch was the full sized cookie… way too much at once for me. The other two batches made 12 cookies…

    So yummy! I had extra filling so serving as a dip for some vanilla wafers.

    Everyone asked for the recipe!

    Can these be frozen?

    1. Chahinez says:

      It sounds like your Easter cookies were a hit! Freezing should be fine for these cookies. Just make sure they are stored in an airtight container to prevent freezer burn. When you’re ready to enjoy them, let them thaw in the refrigerator overnight before serving. If you want to freeze them with the filling, consider placing a piece of wax paper between each cookie to prevent them from sticking together.

      Was absolutely delicious. We opted to just buy a premade ground cracker crust and make one large pie and I used fresh regular lime juice that I got in a big bag from Aldi‘s and I left the lime pulp in. I used 8 ounces of cream cheese and 8 ounces of sweetened condensed milk Because I didn’t know what else to do with the cream cheese. So I added the lime bits with a quarter cup of the lime juice plus I added two more limes. I guess it was more like a3 cup because I made a bigger batch but using your recipe it was absolutely good. I topped it with coconut and let me tell you it’s barely chilled and I can’t even get my fingers my mouth, my spoons off of it. It is so heavenly and delicious and tangy and sour but sweet and just amazing and one day I’ll make it with a little individual cups. In fact, the graham cracker wasn’t the best. It’s rather crumbly in the big pie shape that I prepackaged, but I did it to save time. I stuck it in the fridge for 10 minutes and I kind of ate some of it already. It is absolutely good. It is so good that you wanna lick the batter.

      1. Chahinez says:

        Yay!! So glad it worked out 🙂

  3. Meredith says:

    How can I substitute the vanilla butter emulsion for just vanilla extract and butter? Is it a 1:1 substitution?

    1. Chahinez says:

      Use 1:1 vanilla extract instead of the butter vanilla emulsion!

    These are the best Key lime cookies! Every recipe I get from this page has been absolutely amazing. Keep them coming love!!💗💗

    The batter was a little dryer than I expected and it made for a drier, less chewy cookie. Still tasty luckily!

    1. Chahinez says:

      Sorry about that. Try to use a food scale to measure instead of measuring cups for more accurate measurements. Maybe something was just a bit off. Glad it still turned out tasty!

  6. Sasha says:

    Followed the recipe exactly but the custard came out too thin. Should I just add more cream cheese to thicken it up?

    1. Chahinez says:

      First thing I would try is chilling the filling longer before adding to the cookies. that usually firms it up nicely without changing the flavor balance too much. If you still need to, you can add a little more cream cheese.

  7. Bethany says:

    Making these today and I can’t wait!!! Can these be frozen for a couple of weeks until I get to my family’s for Christmas? Fingers crossed they can!

    1. Chahinez says:

      Yes! You can freeze them for up to 2–3 weeks. Just freeze without the lime wedge or whipped cream topping, then add those fresh after thawing.

  8. ALICIA says:

    Have you tried to do sandwich cookies with this recipe?

    1. Chahinez says:

      I haven’t but that would be delicious! You could bake them slightly smaller and then fill and sandwich them with the key lime filling once both halves are chilled.

  9. jael corinne says:

    if i used graham cracker crumbs how much should i use?

    1. Chahinez says:

      For the main dough, use 1 cup finely crushed graham cracker crumbs (about 7 full sheets). For rolling before baking, use 1/3 cup crumbs (about 2 sheets).

  10. Alicia says:

    do you have to use key limes or can I use a regular lime? having trouble finding key limes now.

    1. Chahinez says:

      Regular limes work fine! The flavor is a bit less tangy than key limes, but still delicious.
