Key Lime Pie Cookies

If there’s one thing I could make every day for the rest of my life, it’d be pie. I like the rolling and the crimping and the filling and the … well, everything. And I (usually) like the thinking pie-making brings. I get all existential and have thoughts like, “is my hand really moving now?! it’s weird that we even exist at all, right now, right here…”

You know, crazy thoughts I used to have more in college when I read too many books and had too many feelings. I remember one night in college staying up all night, listening to this song and thinking way too much about the fact that we all actually exist. (Do you think I’m weird right now? Probably and sorry.) Art school made me angsty; or I went to art school because I was angsty–I’m not sure which one came first. But I do know that pie-making brings back that angst.

The other day I wanted the flavor of pie without my brain going to weird places. I wanted to cut the time in half, but when I closed my eyes, I wanted the flavor to scream key lime pie. So…key lime pie cookies! YES.

Key Lime Pie Cookies

As a person who was raised half my life in Florida, I feel like somewhat of an authority on key lime pie. Here’s the thing: the juice has gotta be fresh. And key limes are like no other. A lot of key lime pie trickery goes on and it usually involves bottled key lime juice or just straight up lime juice. No. And the graham crackers for the crust need to be on point.

In this instance graham crackers are made. No graham flour! Thank the heavens because who wants to go out and buy graham flour for one lil’ ol’ recipe. No one.

Key Lime Pie Cookies


The marshmallow glaze is actually similar to a seven-minute frosting that’s actually more like a three-minute frosting.

When a torch is put up against it, it browns beautifully.

The flavor of key lime pie is here. It’s present in this little cookie.

Serving Size: 24 cookies



  • 1 3/4 cups, plus 1 tablespoon, all-purpose flour
  • 1/2 cup dark brown sugar
  • 1/2 teaspoon baking soda
  • 1/2 teaspoon fine-grain sea salt
  • 3 1/2 tablespoons 50 grams unsalted butter, cut into 1-inch cubes and very cold
  • 2 1/2 tablespoons honey
  • 2 1/2 tablespoons whole milk
  • 1 tablespoons pure vanilla extract

Marshmallow Glaze:

  • 1/4 cup sugar
  • 1 egg white
  • 1/8 teaspoon cream of tartar
  • Pinch salt
  • 1 teaspoon key lime juice
  • Zest from 3-4 key lime


  • Combine the flour, brown sugar, baking soda, and salt in the bowl of a food processor fitted with the steel blade. Pulse or mix on low to incorporate. Add the butter and pulse on and off on and off, or mix on low, until the mixture is the consistency of a coarse meal.
  • In a small bowl, whisk together the honey, milk, and vanilla extract. Add to the flour mixture and pulse on and off a few times or mix on low until the dough barely comes together. It will be very soft and sticky. Lay out a large piece of plastic wrap and dust it lightly with flour, then turn the dough out onto it and pat it into a rectangle about 1-inch thick. Wrap it, then chill it until firm, about 2 hours or overnight.
  • Sift an even layer of flour onto the work surface and roll the dough into a long rectangle about 1/8 inch thick. The dough will be sticky, so flour as necessary. Using a 3-inch scalloped (or not scalloped) biscuit cutter, cut out as many cookies as you can. Reroll the scraps and cut out more. Using a toothpick or skewer (I like to use the blunt end of a wooden skewer for more dramatic dots), prick the dough to form two dotted rows about 1/2 inch for each side of the dividing line. Place the crackers on one or two parchment-lined baking sheets. Chill until firm, about 15 to 20 minutes in the fridge.
  • Preheat the oven to 350 degrees F. Bake for 15 to 25 minutes, until browned and slightly firm to the touch, rotating the sheets halfway through to ensure even baking. Cool the cookies on a cooling rack until room temperature.
  • Meanwhile, make the marshmallow glaze. In a large metal bowl, whisk together 2 tablespoons water, sugar, egg white, cream of tartar, salt and key lime juice. Set bowl over pan of barely simmering water and mix with handheld electric mixer at low speed. Gradually increase speed to high, beating until mixture thickens and becomes a very smooth glaze, about 3-4 minutes. Spread about a teaspoon on each cookie. Using a kitchen torch, torch the tops of each cookie and top with a liberal sprinkling of key lime zest. Note: These get a little funny if they sit out for too long in the heat (hello summer!). If you'd like to make them ahead of time, I recommend making the cookies and then proceeding with the marshmallow glaze just before serving them.

    These are remarkable. They look very attractive as if some piece of art. Well, cooking or baking should is a skill that needs art in it too for presentation. This really works for me. Great job.

    I was raised in Tampa and fully support key lime pie consumption as long as I’m not in charge of juicing all those tiny balls of citrus. Where did you go to art school?

      I feel you! Luckily this recipe doesn’t call for very much key lime juice. I went to University of North Carolina School of the Arts!

    Love that toasted marshmallow glaze!

    As a Floridian, how is it that I’ve never tried key lime pie before? This looks incredibly delish πŸ™‚

      Whaaaa?! Gurl you need to get down to Key West and get you some. I wish I knew the name of the place that serves the best key lime pie down there. But it’s a little shack and the pies are INCREDIBLE!

    Oh hello, love! Lime or lemon anything makes me so happy. This is a very clever and easy way to get similar flavours without needing to fiddle with pie crust. I mean, summer and so much cold cold butter don’t get along very well, do they? At least this only calls for 3.5 tbsp. Not too bad.
