Heat a large skillet (or use griddle) over medium heat. The pan is ready if when you splatter a little water onto the pan surface, the water dances around the pan and eventually evaporates.
Make a well in the center of the flour mixture, pour milk mixture into the well and use a fork to stir until you no longer see clumps of flour. It is okay if the batter has small lumps – it is important not to over-mix the batter.
Lightly brush skillet with melted butter (this is optional if you have a high-quality non-stick pan). Use a 1/4-cup measuring cup to spoon batter onto the skillet. Gently spread the batter into a 4-inch circle.
When edges look dry, and bubbles start to appear and pop on the top surfaces of the pancake, turn over. This takes about 2 minutes. Once flipped, cook another 1 to 2 minutes or until lightly browned and cooked in the middle. Serve immediately with warm syrup, butter, and berries.
