Preheat oven to 350° and lightly spray (2) 12 cup muffin tin(s) with non-stick cooking spray.
In a medium mixing bowl, combine flour and brown sugar together.
Using a pastry cutter, add butter and cut mixture until it resembles coarse crumbs.
Press mixture into the prepared muffin pan and bake for 8-10 minutes, then remove from the oven.
While the crust is in the oven, whisk eggs, corn syrup, sugar, vanilla and salt until well combined.
Stir in pecans and spoon pecan mixture over the crust.
Reduce temperature to 275° and bake for 30 minutes or until filling is set.
Cool on a wire rack.
