In a large bowl, sift together the dry ingredients…flour, baking powder, salt and sugar.
Make a well in the middle and pour in wet ingredients…milk, egg and melted butter; mix until smooth.
Oil the Abeleskiver pan well with a brush. Fill each slot with batter, leaving a little bit of room on top for the pancake to puff up. Optional: place 2 or 3 blueberries on each puff before turning.
After about 30-40 seconds, use chopsticks or a toothpick and carefully turn the puff 90 degrees to cook the side. After about another 30 seconds, turn another 90 degrees to completely cook the puff on all sides.
Once the last side is cooked and golden, about 30 seconds, remove the puffs from pan and set aside to cool.
You can top each puff with fresh blueberries and use a toothpick to hold it in place. Dust the puffs with a light coating of confectioner's sugar.
