Heat the oven to 400° and spray a mini muffin pan with cooking spray.

Use a large circle or flower cookie cutter and cut out as many circles as possible from the pie crust.

Gently press the circles into the pan, careful not to tear a hole.

Whisk the brown sugar, corn syrup, eggs, melted butter and vanilla together, then add the chopped pecans.

Carefully fill the pies nearly full, but do not overfill. Add one pecan half in the middle of the top of each mini pie, if you wish.

Place in the oven and bake for 20 minutes or until lightly browned. Careful not to overbake.

Remove and allow to cool before serving.
