Step 1

Preheat your oven to 350°F (180°C) and line an 8-by-8-inch (20-by-20 cm) metal pan with parchment paper.

Step 2

In a stand mixer fitted with the paddle attachment, beat the butter, sugar, and salt on medium-high speed until light and fluffy, about 2 minutes. Incorporate the eggs, 1 at a time, beating well after each addition. Be sure to scrape the sides of the bowl well.

Step 3

Pause the machine and add the cornmeal, all-purpose flour, whole-wheat flour, and baking powder. With the mixer on low speed, mix until incorporated. Then pour in the milk, buttermilk, oil, and honey and mix just until combined. This should yield a very loose, runny batter. (Small lumps of butter are no problem, but avoid any lumps of flour. If you see them, mix the batter just a little longer or work them out with your fingertips or the tines of a fork.)

Step 4

Pour the batter into the pan and bake for 45 to 50 minutes, or until a tester comes out clean. You’re going to want to start checking the cornbread after 30 minutes, and if the surface turns perfectly golden brown before the time is up, loosely cover the pan with aluminum foil. Let the cornbread cool ever so slightly in the pan on a wire rack prior to slicing. This buttermilk cornbread is best served the day it’s made but keeps for up to 2 days if wrapped well.
