Key lime cooler cookies, made with heaps of lime zest and stored in the fridge. The best summertime cookies!

Iโm a citrus girl, through and through. Itโs pretty great to be me, actually. I can breeze right past a display case of fancy chocolates and order the humble lemon tart. I can pass up a triple chocolate something-or-other in favor of a lemon pรขte de fruit. And when it comes to cookies, I like a small batch chocolate chip cookie as much as the next girl, but the cookies that keep me coming back, stealing one after another all afternoon long? KEY LIME COOLER COOKIES.
These โcoolersโ are sometimes called snowball cookies or Russian tea cakes (and I made pistachio lime matcha snowball cookiesย once before). Iโve also heard them called polvorones or Mexican wedding cookies. I call them delicious. And addicting.
Theyโre basically crisp little cookies covered in powdered sugar. They melt in your mouth. And the punch of key lime is exactly what I need in the summertime.
I actually keep these cookies covered in the fridge, because thereโs nothing like a cold little cookie on a hot day.
But I have even better news than a cold cookie on a hot day! You guys know of my love for butter. Itโs rich, creamy, and the best. Itโs a game changer when it comes to baking. Iโve been working with Kerrygold since the year this blog started (2010โyikes!), and I have faithfully dealt with their half-pound butter bricks. Anytime I would bake, I would just pull out my scale and measure the butter by weight.
It worked just fine, but I silently plead for a butter stick that I could slice a little easier. And then Kerrygold answered my buttery prayers: they started making butter sticks just for baking! I couldnโt believe my eyes when I saw them. I feel like they personally made the sticks for meโlike they knew of my kitchen cries, the poor wrapping job I would do on my remaining butter brick, and my kitchen scale covered in butter.
Kerrygold just gets me. Like a cold cookie on a hot day. Itโs true love. In stick form!
Key Lime Cooler Cookies
Key lime cookies, small batch makes 1 dozen cookies.
Ingredients
- 1/4 cup crushed graham crackers (from about 3 graham cracker sheets)
- 1/4 cup granulated sugar
- zest from 4 Key limes (or 2 regular limes)
- 4 tablespoons Kerrygold unsalted butter (1/2 a stick!), cold
- 1 large egg
- 1/2 cup + 2 tablespoons all-purpose flour
- 1/4 teaspoon salt
- 1/2 cup powdered sugar
Instructions
- Preheat the oven to 350, and line a small baking sheet with parchment paper.
- Crush the graham crackers to get 1/4 cup of crumbs, and set aside.
- In a small bowl, beat together with an electric mixer the sugar and Key lime zest for about 30 seconds.
- Next, slice the cold butter into about 16 pieces, and then add it to the bowl.
- Beat the butter into the sugar until creamy and fluffy, about 45 seconds. Add the egg and beat just until combined.
- Next, sprinkle the flour, graham crumbs, and salt evenly over the surface, and beat until just combined. The dough will be crumbly, use the warmth of your hands to bring it together.
- Have the powdered sugar ready in a shallow dish.
- Scoop out 12 balls of dough, and roll lightly in powdered sugar before placing on the baking sheet, evenly spaced. Reserve the remaining powdered sugar
- Bake for 15 minutes; the cookies will not turn brown. Do not over bake.
- While the cookies are still warm, roll them each in powdered sugar again.

Iโm with you โ cookies from the fridge are so much better in the summer! Canโt wait try these out!
Iโm not sure I see where the crushed graham crackers come in? But these sound delicious!
Sorry, Rebecca! I fixed it :)
Iโm with Rebeccaโฆis the graham โflourโ added with the AP flour?
Yes, I fixed the recipe, sorry.
UM, can you say YUM? These are perfect for summer, adding them to my must make list.
Oh yes, anything lime!! Iโll definitely be trying this one.????
What size cookie scoop do you use for these? Also how long do they last?
Thank you.
Itโs just a small scoopโฆit holds about 2 teaspoons of dough. I would try to eat them in less than 2 days, but they never last that long.
Thank you. Iโm making them now and they flattened some. Any ideas what I should do differently next time? I live in Phoenix if that helps.
How do I avoid flattening of the cookies? I tried them out, the taste was amazing but not the shape.
What else could I roll these in? Powdered sugar makes my teeth itch.
I made them, they were easy to make and delicious but they were flat as a pancake. Any recommendations?
This is so strange! Did you use cold butter? Most cookie recipes call for softened or even room temp butter, but this one intentionally uses cold. It sounds like your butter was warm and the cookies just melted :(
Can you substitute lemon or orange for the lime?
Yes :) Sounds delicious!
