Step 1In a large bowl, whisk the flour with the baking powder, baking soda and salt.
Step 2With a spatula, push the dry ingredients to one side of the bowl. Add the egg to the empty side. Whisk the yogurt (or milk mixture) into the egg, then add the sugar and vanilla.
Step 3Once the wet ingredients are whisked together on one side of the bowl, use the spatula to quickly mix the wet with the dry ingredients. Just stir until blended together; do not over-mix.
Step 4Heat a grill or skillet over medium heat, greasing it with butter or oil. When the grill or skillet is hot, spoon the batter into the desired-size pancakes; the recipe will make about 6 pancakes of about 5 inches in diameter. Cook until the top starts to bubble. Flip over and cook until the other side is lightly browned and cooked through, about 2 minutes.
