Collect all your ingredients: pecans, cake mix, butter, and any extras you love!
Set your oven to 350°F (175°C) and let it warm up while you prepare.
Grease a 9x13 inch baking dish with butter or cooking spray for easy cleanup.
Start by spreading the pecans evenly at the bottom of the dish.
Sprinkle the dry cake mix over the pecans, covering them completely.
Melt the butter and drizzle it over the cake mix, ensuring even coverage.
Pour water over the entire mixture, but don’t stir! Let the magic happen.
Place the dish in the oven and bake for 45-50 minutes, or until golden brown.
Let it cool for a few minutes, then scoop and serve warm. Enjoy!
