In a large pan, preferably 10×15, grease the bottom of the pan or I prefer to use parchment paper to line. Pour the crust mixture onto the greased pan and press firmly to create a crust. Bake in the oven for 10 minutes at 350 degrees.
In a separate bowl, or standing mixer with bowl, combine eggs, corn syrup, sugar, brown sugar, melted butter, vanilla extract, and chopped pecans; mix well. Set aside until the crust is done baking.
After 10 minutes, remove the crust from the oven.
Pour the prepared pecan filling mixture on top of the hot crust. Use a spatula or spoon to distribute evenly.
Place back in the oven. Bake for 35 minutes at 350 degrees
Let cool and serve.
