For the cornbread mix: In extra-large bowl, combine flour, cornmeal, sugar, and salt. Whisk until well combined. Set fine-mesh strainer over bowl. Add baking powder to fine‑mesh strainer and tap side of strainer to sift baking powder into bowl.
Whisk until very well combined, about 1 minute. Transfer cornbread mix to large airtight storage container. (Cornbread mix can be stored at room temperature for at least 2 months.)
To make one batch of cornbread: Adjust oven rack to middle position and heat oven to 375 degrees. Spray inside bottom and sides of 8-inch square metal baking pan with vegetable oil spray.
In large bowl, whisk milk, melted butter, and eggs until combined.
Add 2¾ cups Cornbread Mix and stir with rubber spatula until just combined and no dry mix is visible. Use rubber spatula to scrape batter into greased baking pan and spread into even layer.
Place baking pan in oven and bake until golden brown and toothpick inserted in center comes out clean, 25 to 30 minutes.
