Meanwhile, if you'll be using an electric skillet, heat it to 350 degrees Fahrenheit. Otherwise, heat a heavy cast iron skillet or nonstick griddle over medium-low heat. You’re ready to start cooking your pancakes once the surface of the pan is hot enough that a drop of water sizzles on contact.
Pour the liquid mixture into the dry mixture. Stir until combined, so only a few lumps remain (don't over-mix or your pancakes will be tough!). If you'd like to mix in any totally optional add-ins (like chocolate chips or blueberries), gently fold them in now. Let the batter rest for 5 minutes so your pancakes will be nice and fluffy.
In a mixing bowl, whisk together the flour, baking powder and salt. In a 2-cup liquid measuring cup or another mixing bowl, whisk together the milk, oil, maple syrup and vanilla extract until thoroughly blended. (If your coconut oil solidifies on contact with the cold milk, gently warm it in the microwave just until it liquifies again.)
