Whisk the eggs and milk together to combine. Add in the flour, and beat until the batter is smooth and lump free. Add in any option add-ins you like here.
Heat a nonstick pan over low-medium heat with cooking oil spray. Wipe over excess; pour about 1/3 cup of batter per pancake. Cook pancakes for 1 to 2 minutes, or until bubbles appear on the surface and the bases are golden brown. Flip and cook until golden; transfer to a warmed plate; repeat with remaining batter (spraying/greasing pan between ever second or third pancake if needed).
Serve immediately with yoghurt, ice cream, whipped cream, maple syrup, berries, or any other toppings you like.
