Whisk 1 cup each whole-wheat flour and cornmeal, 1/2 cup sugar, 1 teaspoon baking soda and 1/2 teaspoon kosher salt in a large bowl. Whisk 1 cup buttermilk, 2 eggs and 1/2 stick melted butter; whisk into the flour mixture. Transfer to a buttered 9-inch cast-iron skillet and sprinkle with sesame seeds and pepitas. Bake at 400 degrees F until a toothpick comes out clean, 18 to 20 minutes.
