instructions.
Combine the sugar, corn syrup, eggs, butter, and vanilla in a small saucepan and cook over medium heat stirring often.
Mix brownies according to package instructions.
Pour brownie batter into a greased 13×9 inch pan and place in oven to bake for 20 minutes. * see note about cooking time below
As the brownies bake the filling in the saucepan should have thicken enough to coat your spoon (about 15 minutes). Stir the pecans into the mixture and continue to cook for 2-3 minutes until the mixture reaches the consistency of runny oatmeal. You want it to be loose enough to pour over the brownies but not liquid.
When the brownies have finished pre-baking remove them from the oven and pour the pecan pie filling over them spreading it out to cover the brownies completely.
Place them back in the oven and bake for 25-30 minutes or until the filling only jiggles slightly in the middle when you move the pan.
Let cool to room temperature before cutting.
