Step 1

Preheat your oven to 350 degrees F. Grease a 9-inch x 13-inch baking pan (glass or metal) and set aside.

Step 2

Prepare the brownie batter according to package directions. Pour the brownie batter into the prepared baking pan.

Step 3

Bake for 20 minutes (or 10 minutes less than the package directions indicate).

Step 4

While the brownies bake, mix together the sugar, corn syrup, eggs, butter, and vanilla in a medium mixing bowl. Stir in pecans.

Step 5

After brownies have partially baked, remove the pan from the oven and pour the pecan pie filling over the top. Spread the topping into an even layer.

Step 6

Place the brownies back in the oven and bake for 25 to 35 minutes or until the filling only jiggles slightly in the middle when you move the pan.

Step 7

Remove the brownies from the oven and let cool to room temperature before cutting into 20 squares.
