Instructions
Preheat the oven to 325-degrees and grease a 9-inch by 13-inch baking dish.
Bottom Layer
Add the cake mix to a medium-sized bowl.
Next, add the melted butter, one egg, and mix well.
Scoop out 2/3 of a cup and set it aside.
Press the remainder of the cake batter into the baking dish and bake for 15-20 minutes or until the edges are light golden brown.
Top Layer
Add the reserved 2/3 cup of batter (from the bottom layer) to a large bowl.
Next, add three eggs, brown sugar, corn syrup, and vanilla extract and mix well.
Add the chopped pecans and mix. Pour the top layer over the cooked bottom layer and bake again for 50-60 minutes or until a cake tester or toothpick comes out clean.
Cool and serve. Enjoy!!!
