Preheat the oven to 325 degrees. Line a 9X9 baking dish with parchment paper and spritz with non-stick cooking spray.
In a food processor, pulse the ingredients for the crust. Transfer to a baking dish and press into an even layer.
Bake for 12 to 15 minutes. Remove from the oven and allow to cool.
Meanwhile, melt butter with the granulated monkfruit in a medium-sized saucepan over medium heat. Bring to a boil and allow to brown without stirring until it reaches a deep caramel color, about 5 to 7 minutes.
Remove from heat and stir in the vanilla and brown sugar substitute.
Add pecans to the crust in an even layer. Pour syrup over the pecans.
Bake for 17 to 20 minutes or until the syrup bubbles.
Cool completely on a wire rack before slicing and serving.
