Preheat oven to 350 degrees and grease a Bundt pan.
Whisk the melted butter, brown sugar, corn syrup and salt until combined. Add in the pecans and mix again. Pour into the bottom of the bundt pan and set aside.
In a large bowl, beat all of the cake batter ingredients until just combined (be careful not to overmix). Pour over the butter mixture.
Bake for 40-45 minutes or until a toothpick inserted in the center comes out clean. Remove from oven.
Let it sit for 10 minutes, then run a knife along the edges to release the cake from the pan. Flip onto a plate and let it fully cool before slicing. Enjoy!
