Four Grain Waffles

Four-Grain Waffles
1 1/2 cups buttermilk
2 large eggs
1/4 cup vegetable oil plus extra for greasing
3/4 cup all-purpose flour
1/2 cup whole wheat flour
1/2 cup oat flour
1/4 cup cornmeal
2 Tbs sugar [which I reduced to 1 Tbs, you can probably omit altogether]
1Tbs baking powder
Preheat a waffle iron to medium heat.
Combine the buttermilk, eggs and oil in a large bowl.
In a separate bowl, combine the flours, cornmeal, sugar and baking powder. Add the liquid ingredients to the dry ingredients and mix by hand with a wooden spoon just until the batter is evenly moistened.
Lightly brush the preheated waffle iron with vegetable oil. Ladle about 1/3 cup of batter (check the waffle iron manufacturer’s instructions, since sizes may vary) into the waffle iron and cook until the waffles are golden brown and the iron opens easily without tearing the waffles, about 3 minutes. If necessary, keep warm in a 200°F/ 90°C oven while you finish cooking the remaining batter.
