Preheat oven to 350°f
Whisk together the eggs, corn syrup, sugar, oil, vanilla, and salt. Mix in the pecans and pour into a round pie dish.
Separately, whisk together the flour, sugar, baking powder, and salt. Add the chilled butter and press with a fork into the dough. Add the milk and lightly stir until a dough is formed. Transfer dough to a lightly floured surface and press into a 1 inch thick circle. Using a 2-inch round cookie cutter, cut out circles and place them on top of the pecan filling until there is no more dough left.
Brush a little extra milk on top of each biscuit and sprinkle with coarse sugar.
Bake for 45 minutes. Cool completely before slicing.
Sprinkle with a little extra coarse salt before serving, for decoration and to cut the sweetness.
