These key lime pie cookie cups are seriously the cutest version of key lime pie I’ve ever made! And I’ve made a lot, y’all. The only thing different from my OG recipe is I swap out the graham cracker crust for pre-made sugar cookie dough. It holds the filling better and makes life easier when you have a crowd to feed. That’s why I keep these in rotation for birthdays, baby showers, or after-dinner sugar cravings.

How to Make Key Lime Cookie Cups
Bake the Cookie Cups

Step 1: Roll the cookie dough into balls and place each one in the bottom of each muffin tin. Bake the cookies until golden brown.

Step 2: Press the center of each cookie with a spoon to form the cup shape, let them cool in the pan, then carefully transfer to a rack to finish cooling.
Make the Filling

Step 3: Combine the egg yolks, key lime juice, sweetened condensed milk, and pure vanilla extract in a medium bowl. Whisk together until creamy and well-mixed.

Step 4: Cook the mixture in a pot over medium-low heat, stirring until warmed through, then take it off the heat and let it cool.

Ingredients
- 1 package Pillsbury Ready to Bake! Sugar Cookie Dough
- 3 large egg yolks
- ½ cup key lime juice
- 14 ounces sweetened condensed milk 1 can
- 1 teaspoon pure vanilla extract
- Whipped cream and lime zest for garnish
Instructions
For the Cookie Cups:
- Preheat oven to 350 degrees.
- Spray a 24 mini muffin pan with non-stick baking spray.
- Roll each separate cookie into a ball and place in the bottom of each muffin tin.
- Bake cookies for 10-12 minutes or until golden brown. Remove cookies from oven and gently press a spoon in the center of each baked cookie to make the shape of the cup.
- After 10 minutes, gently remove cookie cups from the muffin pan and place on a cooling rack until completely cooled.
For the Key Lime Filling:
- Whisk together egg yolks, key lime juice, sweetened condensed milk, and pure vanilla extract.
- Pour into a medium sized pot and saute over medium to low heat to cook through the eggs.
- Keep on heat and stir for 12-14 minutes until nice and warm. Remove and allow to cool.
To Assemble:
- Fill a ziploc bag with snipped side or piping bag with key lime curd mixture.
- Pipe key lime curd into direct centers of each cookie cup until filled.
- Next garnish with whipped cream and lime zest and refrigerate for at least one hour and serve.
Notes
- Zest your limes before you juice them. It’s way easier to get the zest off while the limes are still whole. And don’t go too deep, boos! Avoid the bitter white pith under the green skin. There’s nothing worse than bitter key lime pie cups.
- Roll your limes on the counter before juicing. Press down with your palm and give them a good roll to get the most juice out.
- Check your cookie cups early. Some ovens run hot, so peek in a couple minutes before the timer to keep them from overbaking.
- Shape the cups while they’re still hot. Grab a spoon and press the centers down gently while the cookies are fresh out the oven. They’ll firm up quick as they cool.
- Fridge: Store your key lime pie cups in an airtight container. They will keep for up to 5 days. If possible, wait to add the whipped cream topping right before serving.
- Freezer: I don’t recommend freezing the full key lime pie cups with the filling boos, but you can bake the cookie cups ahead of time and freeze those on their own. Just pop them in a freezer-safe container and they’ll be good for up to 2 months.

Recipe Help
Yup, just go with something soft like sugar cookie dough, oatmeal, or chocolate chip. You want dough that’s easy to press into the muffin tin for this cookie cups recipe.
Keep an eye on the edges, boos. Once they start to turn golden and the centers look set (not raw), they’re good.
Yep, just divide the dough into 12 balls instead of 24. Follow the same steps, but you will probably need to bake them a couple minutes longer since they’re bigger.
I can’t wait to try these! Didn’t I see a tool somewhere that would push the cookie down evenly in the little mini pan? Was it hard to do with a spoon? Also, I want to say that here in Ohio, I sometimes see Key Lime pies that are green! Yuk! Your filling is the real thing! Thank you!
Hi Nancy! I can’t wait for you to try these either. They are super simple to make. You can actually just use a small spoon and you won’t have any problems at all. I believe real key lime pie isn’t green! Thanks again Nancy!
These are too cute! Key lime pie is good on its own, but the cookie crust brings it over the top!
Yes it is a fun twist! I really enjoyed these!
I don’t like bought cookie dough wonder if there is home made dough I can make instead ?
Hi Heidi, I haven’t tried it with homemade dough but I say go for it. Make sure that your dough is a more chewy cookie dough instead of a harder one since the dough needs to be bendable for the cups. Enjoy! Can’t wait to hear how they turn out!
These are so adorable! Perfect for Spring. 🙂
Thanks so much Dana!!

Chicago has had a brutal winter, and I am not sure it is over yet. I can see why these Key Lime cookie cups got your attention- it is like being in the Florida Keys ( south Florida). These are delightful!

Nope I don’t think winter is over just yet but I hope it is soon.
This is one of those recipes that I can almost taste while reading, Jocelyn! I absolutely adore lemon curd, so I know I’d love these with lime curd in. What a fabulous recipe invention. Pinning these for sure!
Thanks so much Helen! I too am a huge fan of lemon curd!!
