In a large bowl, combine the flour, butter, and salt. Use a pastry cutter or two knives to cut the butter into the flour until the mixture resembles coarse crumbs.
Slowly add the cold water, a few tablespoons at a time, and mix until the dough comes together. Form the dough into a ball and wrap in plastic wrap. Refrigerate for at least 30 minutes.
Preheat oven to 350 degrees F (175 degrees C). Grease a 12-cup muffin pan.
On a lightly floured surface, roll out the dough to 1/4-inch thickness. Cut circles using a 3-inch round cutter and fit into the muffin cups. Trim off any excess dough.
In a medium bowl, combine the eggs, sugar, vanilla extract, and evaporated milk. Mix until well blended.
Fill each muffin cup with the egg mixture. Bake for 25 to 30 minutes, until golden brown.
Allow to cool before serving.
