Buttermilk Apple Corn Oat Pancakes

I used to hand grind all of my flour as a multi grain (and seed) mixture in my grain mill and let the batter sit overnight (to soften) and make these in the morning to arouse sleeping guests. But now that our ceilings are falling down and we can't afford to heat our home above 45 degrees, we encourage people to stay elsewhere.

1 cup whole wheat flour
1/4 cup cornmeal
1/4 cup rolled oats
3 tablespoons sugar or favorite sweetener
1 1/2 teaspoons baking powder
1/2 teaspoon baking soda
1 teaspoon salt
1 1/2 cups low-fat buttermilk
1 tablespoon vegetable oil
2 large eggs
chop apple into thin slices and place a few on raw side of pancake.

Combine flour sugar, baking powder, baking soda, and salt in a large bowl. Combine buttermilk, oil, eggs, stirring; add to flour mixture, stirring until moistened.
