Preheat the oven to 350 degrees. Grease a 9x13 baking dish with nonstick cooking spray.
In a large mixing bowl, add the 1 ¼ cups all-purpose flour, ¼ cup brown sugar, ½ cup granulated sugar, 2 teaspoons baking powder, and ¼ teaspoon salt. Whisk until combined.
Add the ¾ cup whole milk and 1 teaspoon vanilla extract to the dry ingredients. Whisk until all ingredients are combined.
Pour the batter into the prepared baking dish. Set aside.
In a separate bowl, add the melted ½ cup salted butter, ½ cup brown sugar, and 1 ¾ cups chopped pecans. Mix until combined.
Evenly sprinkle the pecan mixture over the batter in the baking dish. Don’t mix.
Gently pour the 1 cup hot water over the top. Don’t mix.
