Add all ingredients except butter to blender and process until smooth. Let sit while the skillet is heating.
Heat a cast iron skillet or griddle with a medium flame until hot and then add 1 teaspoon of butter.
Slowly pour pancake mix into skillet to make 3 inch pancakes. When bubbles begin to form, flip pancakes. Continue until all batter has been used. Use the second teaspoon of butter, half way through, to grease pan.
Serve with butter and maple syrup.
If pancakes spread out too much, the griddle or skillet is not hot enough.
