1/2 sticks (12 tablespoons) unsalted butter, plus more for serving
1/3 cup maple syrup
1 cup cold buttermilk
1/4 cup whole milk
3 eggs, lightly beaten
1 1/2 cups cornmeal
1/2 cup all-purpose flour
1/2 cup whole-wheat flour
1/4 cup sugar
1/2 tablespoons baking powder
1 1/2 teaspoons salt
1/2 teaspoon baking soda
Instructions
Set the oven to 375 degrees Fahrenheit.
Melt the butter in a sizable cast-iron skillet over medium heat, stirring the pan to cover the bottom and sides. The butter should next be heated until it stops foaming and turns a light brown color. Keep an eye on it to prevent burning. Place the skillet aside and pour the brown butter into a big bowl. Butter, buttermilk, and whole milk are all whisked into the butter after the maple syrup. Next, whisk the eggs in. Cornmeal, all-purpose flour, whole wheat flour, sugar, baking soda, baking powder, and salt should all be added. Mix everything together by whisking.
Fill the cast-iron skillet with the cornmeal batter. Bake for about 20 minutes, or until the middle is firm, the sides are golden brown, and a toothpick inserted into the center comes out clean. After a little cooling period, serve warm with butter.
