48Marias cookies,plus more for garnish, about 1 ½ (4.9-oz) packages
Lime zest,for garnish
Instructions
Add the sweetened condensed milk, evaporated milk, key lime juice, and vanilla extract to a blender and blend until smooth. Set aside.
Line a 7x7-inch baking pan with an even layer of Maria’s cookies. I used 12 cookies per layer - 9 cookies side by side, then 3 cut in half and placed in the empty spaces.
Pour a thin layer of the lime mixture (about ¼ of the mixture) over the cookies. Spread it out evenly. Repeat this layering process with the remaining Maria’s cookies and lime mixture until all the ingredients are used, creating a total of 4 layers. The final top layer will be the lime mixture.
Cover and refrigerate for at least 4 hours until firm and set.
Garnish with lime zest and a couple of crushed Marias cookies for crunch.
Notes
Can’t find key limes? You can use regular limes or even lemon; it just won’t have as sharp a flavor.
Pan size: If you don’t have a 7x7 pan, you can use an 8x8. You can also double the recipe and use a 9x13-inch baking dish.
Texture: Carlota de limón is a soft-set dessert like an icebox cake. If you want a more firm texture, you can place it in the freezer until it reaches your desired firmness.
Cookies: Traditionally, this dessert is made using Marias cookies, but you can use graham or animal crackers.
