1 cup milk
1 cup whole wheat flour or whole grain pancake batter
1/4 cup granulated sugar
1 teaspoon vanilla extract
4 T butter
Preheat oven to 450 degrees. Place the oven rack on the middle rack of the oven. Place a large, cast iron skillet in the oven until hot and sizzling. While pan is heating, prepare your batter.
In a large bowl or blender, beat the eggs until light and frothy. Add milk, flour, sugar, and vanilla extract. Beat for 5 minutes more. The batter will be thin, but very smooth and creamy.
Pull out the oven rack with pot holders and add the butter to the skillet. Be very careful because the pan will be super hot, so I don't touch it directly at all.
In a minute, open the oven door and tilt the pan, evenly coating the bottom of the pan with the butter. Pour the prepared batter into the hot skillet, all at once, and immediately return the skillet to the oven. Bake for 15 mins.
