Begin by warming a skillet on the stove to about medium heat.
Whisk the milk kefir, sugar, baking soda, baking powder, salt, oil, cinnamon, vanilla, and eggs in a bowl until well combined.
Next, whisk in three cups of flour a little at a time until it is all incorporated.
Add splashes of milk and stir if batter is to thick.
Add mini chocolate chips or blueberries to batter if desired.
Add coconut oil or butter to the pan/griddle and swoosh it around until the pan is well coated.
Using a 1/4 measuring cup, scoop out batter and pour it onto the pan.
Allow the pancakes to cook until you see small bubbles forming on top, then flip. Continue to cook them until they are done all the way through.
