Stir eggs, baking powder, buttermilk, vanilla bean, and sugar together in a bowl. The batter should be smooth and without lumps. 

Gently fold the blueberries into the batter. 

Heat a large pan and melt butter on it. Drop spoonfuls of batter onto the pan, and fry them for a couple of minutes on each side.

Serve the blueberry pancakes warm with the remaining fresh blueberries, syrup, and Greek yogurt. You can serve the blueberry pancakes with any toppings you desire - try, for example, fresh banana, some chopped chocolate, or homemade jam. 

They are perfect for the brunch table on a Sunday morning, as a dessert, or a delicious afternoon snack.
