Latin American quiz...
bushwick girl is always a trustworthy source :) but in case you want to look at other options...
I got chowser's cookie link from a chow search, but sometimes sometimes there's just too much to wade through here, although there are a few interesting flavor variations for the tres leches in your link, chocolate, coconut, plus I have a recipe in lime, if the OP is interested. Always good to have options.
You're the search queen. Thanks for the kind word, ghg. :)
My favorite tres leches cake recipe, you can't miss with these guys:
I've had this recipe for some time, don't know where it came from. They're easy and good:
Alfajores de Maicena
Cornstarch Shortbread Cookies filled with Dulce de Leche
2 sticks unsalted butter at room temperature
1/2 cup granulated sugar
1 egg plus one yolk
1 teaspoon vanilla, or more, to taste
2 cups flour
1 cup cornstarch
1 teaspoon baking powder
1/2 teaspoon table salt
1-2 cups dulce de leche (make your own or store bought is fine
)powdered sugar (optional)
In the bowl of a stand mixer, cream the butter and the sugar. Add in the egg, yolk and vanilla and beat over medium speed until incorporated. In a separate bowl, mix the flour, cornstarch and baking powder together. Add the flour mixture to the butter mixture and continue mixing until it forms a consistent dough. You don't need a stand mixer to make these, I do it by hand.
Remove the dough from the mixer and divide the dough into two balls. Wrap the balls in plastic wrap and refrigerate for at least half an hour or overnight.
Preheat the oven to 350 degrees Fahrenheit. Unwrap the dough and roll it out (it will be cold and stiff at first) onto a floured surface. Roll the dough out to about 1/4 inch thickness, then cut with a small round cutter (or a juice glass). Repeat the rolling and cutting until you have used all the dough. Place the cookies on a parchment-paper lined cookie sheet, and bake for 15 minutes, just until the edges start to brown.
Let the cookies cool completely, and then place a generous spoonful of dulce de leche on one cookie and top with another cookie to make a sandwich. Gently press cookie together. Cover in sifted powdered sugar, if desired, or dip half way into melted dark chocolate.
