In a medium bowl, whisk together the flour, brown sugar, baking powder, baking soda and salt. In another larger bowl, whisk the eggs until blended. Then whisk in the Greek yogurt, milk and vanilla extract.
Stir the dry ingredients into the wet ingredients until just combined, being careful not to over mix; a few lumps are okay.
Heat a large nonstick pan over medium heat. Spray with nonstick cooking spray.
Using a ⅓-cup measuring cup, pour 3-4 circles of batter into the pan. Cook until the pancakes are puffed on top and golden brown on the bottom, 2-3 minutes, then flip and cook on the other side until risen and cooked through, 1-2 minutes more.
Serve with maple syrup, and fresh fruit, as desired.
