Heat a griddle or large frying pan over medium-low to medium heat; grease with butter.

Beat the eggs, milk, and vanilla until light and foamy, about 3 minutes at high speed of a stand or hand mixer. Stir in the melted butter or oil.

Add the flour, salt, baking powder, and sugar, stirring just to combine. A few lumps are OK. Set the batter aside to rest for a couple of minutes.

Drop the batter by 1/4 cupfuls onto the prepared pan. Sprinkle 1 tablespoon berries on top of the pancake.

Cook the cakes till they're golden brown on the bottom, about 2 minutes. Flip them over, and cook till the other side is golden, 2 to 2 1/2 minutes.

Serve the pancakes immediately. Or transfer them to a platter, cover, and keep warm in a 200°F oven. Enjoy with butter and maple syrup.
