Prepare pie dough either from scratch using your favorite recipe or use a store bought, ready-to-bake pie dough.
Once the dough is placed in the pie dish, using a fork, prick small holes along the bottom part of the pie dough. Place in the heated oven for about 20 minutes or until just turning slightly brown. Take out of the oven and set aside to cool.
In a saucepan over low heat, or in a double boiler, melt the butter and chocolate chips. Set aside.
In a large mixing bowl whisk together eggs and brown sugar until fully incorporated. Add vanilla, Lyle’s Golden Syrup and Dark Kayro Syrup to fully blended. Stir in chopped pecans and melted chocolate chips and butter mixture. Set aside.
Remove the chocolate bar from the package, reserving 5 – 7 pieces for topping the pie. Chop the remaining chocolate bar into small pieces and place in the bottom of the baked pie crust. Pour the egg, sugar and chocolate mixture over to fill the pie dish.
Using the ¼ cup pecan halves, place them in a decorative manner around the edge of the pie dish, with 3 – 5 in the center. Place the reserved 5 – 7 pieces of chocolate around the pecan halves in the center of the pie.
Place in the oven on the middle rack and bake for 25 – 30 minutes. Check the pie after this amount of time, and place foil around the edges to protect the crust from turning too brown. Continue to cook for another 20 minutes or until done. Check for doneness by gently and carefully shaking the oven rack to see if the pie mixture giggles. If it still giggles, then it is not done yet.
Once the pie is done, remove from the oven and place on a cooling rack to rest for 20 – 30 minutes before cutting into serving pieces.
