I’ve also made a Maple Pecan Pie and it’s outstanding! Will my Pecan Pie Be runny if I don’t use Corn Syrup? Feel free to try maple syrup or molasses in place of the vanilla. No 2 cups of corn syrup in this pie that’s for sure! Occasionally I’ve added a dollop of molasses instead of vanilla it works well. They called for brown sugar and just a little white sugar. I was surprised that the traditional pecan pie recipes didn’t call for molasses or pure maple syrup as a corn syrup substitute.
