Preheat oven to 325° F. Spray 2 muffin tins with nonstick spray.
Using a 3 ½ inch or 4” round cookie cutter, cut out pie crust and place in circles of dough in muffin tin.
Sprinkle pecans and chocolate evenly in bottom of piecrust; set aside.
Combine corn syrup and next 3 ingredients in a large saucepan,and bring to a boil over medium heat.
Cook, stirring constantly, 3 minutes. Remove from heat.
Whisk together eggs and next 4 ingredients.
Gradually whisk about one-fourth hot mixture into egg mixture; add to remaining hot mixture, whisking constantly. (If some of your egg bits solidify, pour it through fine mesh strainer before pouring into your pie shell.)
Pour filling into prepared piecrust, carefully trying not to overfill. Overfilling will make the mini pies harder to remove from the muffin tin. (I used a 1 ounce cookie/ ice cream scoop to add the filling to the pie crusts.)
Top each pie once filled with a pecan half.
Bake at 325° for approximately 25 minutes or until set.
Cool in pan 5 – 10 minutes, then remove pies from muffin tin to cool completely on wire rack.
